LIVE WALLPAPER DISPLAY METHOD AND APPARATUS, AND ELECTRONIC DEVICE

TECHNICAL FIELD

Embodiments of this application relate to the terminal display field, and more specifically, to a live wallpaper display method and apparatus, and an electronic device.

BACKGROUND

Currently, for example, where an electronic device is a mobile phone, screen ratios of most mobile phones are 16:9 or 20:9. Consequently, the screen ratio is close to 2:1, and a portrait mode is used in most scenarios. Therefore, both a home screen application page and a lock screen application page on the mobile phone are in a portrait orientation. However, on some large-screen electronic devices (such as a foldable screen device or a tablet computer), to meet a use habit of a user, system applications such as home screens and lock screens of the electronic devices can be displayed in a system direction. However, a current live wallpaper (for example, a super wallpaper live theme) and always-on display support in only the portrait orientation. If a live wallpaper theme is introduced to the large-screen device, a final display direction of the live wallpaper, and a final always-on display direction, may be different from a current system direction of the electronic device, resulting in a reduction in user experience.

Therefore, a new live wallpaper display method urgently needs to be provided, so that when the live wallpaper (for example, the super wallpaper theme) is introduced to the electronic device, animations of home screen display, lock screen display, and always-on display of the electronic device can be associatively displayed, thereby improving use experience of the user.

SUMMARY

This application provides a live wallpaper display method and apparatus, and an electronic device. According to the method, a lock screen display and an always-on display can be performed based on a system direction of an electronic device. When a live wallpaper is a super wallpaper theme, animations of home screen display, the lock screen display, and the always-on display of the electronic device can be associatively displayed, thereby improving use experience of a user.

According to a first aspect, a live wallpaper display method is provided, where the method is applied to an electronic device, the electronic device uses a live wallpaper theme, and the method includes: displaying a screen-off wallpaper; and when a screen-on operation is detected, displaying, to a screen-on wallpaper, from animation effect of switching from the screen-off wallpaper to the screen-on wallpaper, where display directions of the animation effect and the screen-on wallpaper can change with rotation of a body of the electronic device, and the live wallpaper theme includes the screen-off wallpaper and the screen-on wallpaper.

Optionally, the screen-on wallpaper includes a lock screen wallpaper and/or an unlocking wallpaper.

The unlocking wallpaper may also be referred to as a home screen wallpaper, and the screen-off wallpaper may also be considered as an always-on display.

Optionally, the screen-on operation may be an unlocking operation.

Optionally, that display directions of the animation effect and the screen-on wallpaper can change with rotation of a body of the electronic device includes: if a body direction of the electronic device rotates from a vertical direction or a partially vertical direction to a horizontal direction or a partially horizontal direction, changing the display directions of the animation effect and the screen-on wallpaper from a portrait orientation to a landscape orientation.

In embodiments of this application, for a problem that the live wallpaper theme can only be displayed in a portrait orientation and cannot be displayed in different system directions of the electronic device in the conventional technology, the live wallpaper display method in which the live wallpaper theme can be displayed in different directions based on the body direction of the electronic device is proposed. When a screen of the electronic device is turned on, the animation effect of switching from the screen-off wallpaper to the screen-on wallpaper is displayed, and the screen-on wallpaper is displayed. The display directions of the animation effect and the screen-on wallpaper can change with the rotation of the body of the electronic device, the screen-off wallpaper can also be displayed in different directions, and visual experience of a user can be improved.

With reference to the first aspect, in an implementation, the method includes: when the screen-on operation is detected, in response to unsuccessful unlocking of the electronic device, displaying, to the lock screen wallpaper, from animation effect of switching from the screen-off wallpaper to the lock screen wallpaper.

In other words, if the electronic device fails to be unlocked, in this case, because the unlocking operation is performed, the screen of the electronic device is turned on, displays the animation effect of switching from the screen-off wallpaper to the lock screen wallpaper, and ends up as a lock screen page after display of the animation effect is completed.

The case in which the electronic device fails to be unlocked may be a case in which a fingerprint does not match, facial recognition fails, an unlocking control is incorrectly pressed, or the like. This is not limited in this application.

In embodiments of this application, the unlocking operation is performed on the electronic device when the screen-off wallpaper is displayed. Even if the unlocking fails, the animation effect of switching from the screen-off wallpaper to the lock screen wallpaper is displayed, and the screen ends up as a lock screen wallpaper display page. In this way, even if the user fails to unlock the electronic device, the user can still obtain good visual experience.

With reference to the first aspect, in an implementation, the method includes: when the screen-on operation is detected, in response to successful unlocking of the electronic device, displaying, to the unlocking wallpaper, from animation effect of switching from the screen-off wallpaper to the unlocking wallpaper, or displaying, to the unlocking wallpaper, from animation effect of switching from the lock screen wallpaper to the unlocking wallpaper.

In an implementation, the electronic device is unlocked when the electronic device is in an always-on display state. When the unlocking succeeds for one time, the screen of the electronic device displays the animation effect of switching from the screen-off wallpaper to the unlocking wallpaper, and ends up as an unlocking page after the display of the animation effect is completed.

In another implementation, the electronic device is unlocked when the electronic device is in an always-on display state. The unlocking fails for one time. In this case, because the unlocking operation is performed, the screen of the electronic device is turned on, displays the animation effect of switching from the screen-off wallpaper to the lock screen wallpaper, and ends up as a lock screen page after the display of the animation effect is completed. In this case, when the electronic device is unlocked for another time and the unlocking succeeds, the screen of the electronic device displays the animation effect of switching from the lock screen wallpaper to the unlocking wallpaper, and ends up as an unlocking page after the display of the animation effect is completed.

In embodiments of this application, the unlocking operation is performed on the electronic device when the screen-off wallpaper is displayed. Regardless of whether the unlocking succeeds after one attempt or after a plurality of attempts, wallpaper display corresponding to the electronic device has good visual continuity.

With reference to the first aspect, in an implementation, the live wallpaper theme is a super wallpaper theme. In a display process of the super wallpaper theme, themes of the screen-off wallpaper and the screen-on wallpaper of the electronic device are the same, and pictures of the screen-off wallpaper and the screen-on wallpaper are in continuity with each other.

In embodiments of this application, when the live wallpaper is the super wallpaper theme, screen-off wallpaper display and screen-on wallpaper display (the lock screen wallpaper and/or the unlocking wallpaper) can end up achieving live wallpaper animation effects associatively in different directions of the electronic device, which further improves the use experience of the user.

With reference to the first aspect, in an implementation, the displaying a screen-off wallpaper includes: when an always-on display style is used, storing display resources in a first direction and a second direction; and obtaining display resources in a third direction and a fourth direction based on the display resources in the first direction and the second direction; and displaying the screen-off wallpaper based on the body direction of the electronic device and the display resources. The first direction and the third direction have an included angle of 180° in the horizontal direction, and the second direction and the fourth direction have an included angle of 180° in the vertical direction.

For example, the electronic device is a mobile phone. A natural coordinate system of the mobile phone is used as a basis, a first direction is one of a positive direction of an x-axis and a negative direction of the x-axis, and a third direction is the other of the positive direction of the x-axis and the negative direction of the x-axis. The second direction is one of a positive direction of a y-axis and a negative direction of the y-axis, and the fourth direction is the other of the positive direction of the y-axis and the negative direction of the y-axis.

System directions include the first system direction, the second system direction, the third system direction, and the fourth system direction. When the electronic device is placed vertically, the first system direction and the third system direction are perpendicular to the left side of the electronic device, and form an included angle of 180° on a plane on which the screen of the electronic device is located. The second direction and the fourth direction are perpendicular to the upper side of the electronic device, and form an included angle of 180° on the plane on which the screen of the electronic device is located.

Optionally, the display resource in the first system direction includes a bitmap resource in the first system direction, and may further include another display resource. This is not limited in this application.

Optionally, the display resource in the second system direction includes a bitmap resource in the second system direction, and may further include another display resource. This is not limited in this application.

Optionally, the display resource in the third system direction includes a bitmap resource in the third system direction, and may further include another display resource. This is not limited in this application.

Optionally, the display resource in the fourth system direction includes a bitmap resource in the fourth system direction, and may further include another display resource. This is not limited in this application.

The electronic device performs byte reversal on the display resources (for example, the bitmap resources) in the first system direction and the second system direction, to obtain the display resources in the third system direction and the fourth system direction, thereby implementing the always-on display in different system directions. Optionally, the bitmap is stored in AGRB_4444 and RGB565 formats, two bytes represent one pixel, and bitmap reversal is implemented by reversing a byte sequence (that is, reordering bytes).

In embodiments of this application, always-on display in the four system directions of the electronic device can be implemented based on the current system direction, a display location in the current system direction, and display resources in two system directions, and the display resources corresponding to the four system directions do not need to be stored. The byte reversal only needs to be performed on display resources in two mutually perpendicular system directions, to implement the always-on display in the four system directions, and reduce storage occupation of the electronic device. In addition, a byte rotation speed in embodiments of this application is far faster than a picture rotation speed used in the conventional technology, and display efficiency of the electronic device can be improved.

With reference to the third aspect, in an implementation, the performing always-on display on a screen-off page based on the current system direction of the electronic device includes: calculating shift information in the current system direction relative to the screen based on a ratio of a screen height in the current system direction to a screen height in an original system direction; and performing the always-on display based on the current system direction and the shift information.

The original system direction is a system direction before the system direction of the electronic device is switched to the current system direction. For example, the system direction of the electronic device is the first system direction. The user changes the device posture of the electronic device, so that the system direction of the electronic device is switched to the second system direction. In this case, the current system direction of the electronic device is the second system direction, and the original system direction of the electronic device is the first system direction.

The shift information includes one or more of a top margin, a shift range, and a shift distance, and may further include other information. This is not limited in this application.

In addition, an interval at which the shift occurs is not limited in this application. The shift may be performed at any equal intervals, or may be performed at any unequal intervals.

In embodiments of this application, for the always-on display in different system directions, a fixed initial location, shift range, and shift distance are no longer used. Instead, the proper shift information is adaptively calculated by using the height in the current screen direction, and the always-on display and pixel shift for screen burn-in protection in different system directions are implemented based on the shift information, so that screen burn-in caused by the always-on display can be prevented more effectively, and a service life of the electronic device is prolonged.

With reference to the third aspect, in an implementation, the method further includes: receiving a notification of unlocking the electronic device; displaying the live wallpaper on the lock screen page based on the current system direction of the electronic device; and displaying a home screen wallpaper on the home screen based on the current system direction of the electronic device.

The home screen wallpaper may be understood as an unlocking wallpaper.

It should be understood that when the user performs an unlocking operation on the electronic device, the electronic device receives the notification of unlocking the electronic device. Before the unlocking operation is performed on the electronic device, the electronic device is in a screen-off state or on an always-on display page.

Optionally, when the electronic device is unlocked, if the current system direction of the electronic device is different from a display direction of the screen-off page, the lock screen page displays pictures of the live wallpaper dynamically rotating from the display direction of the screen-off page to the current system direction.

In embodiments of this application, the electronic device uses the live wallpaper. When a display interface of the electronic device is on the screen-off page, and the current system direction of the electronic device is the same as the display direction of the screen-off page, the user performs a screen unlocking operation on the electronic device when the current system direction does not change, and the display interface of the electronic device sequentially displays a screen-off wallpaper, a lock screen wallpaper (the live wallpaper), and the home screen wallpaper. In addition, display directions of the screen-off wallpaper, the lock screen wallpaper, and the home screen wallpaper are the same as the current system direction, and can conform to visual inertia of the user. In addition, when the live wallpaper is the super wallpaper theme, the animations of the always-on display, the lock screen display, and the home screen display of the electronic device can be associatively displayed, which improves the use experience of the user.

Alternatively, when a display interface of the electronic device is on the screen-off page, and the current system direction of the electronic device is different from the display direction of the screen-off page, the user performs a screen unlocking operation on the electronic device. There is a process of a direction, of the live wallpaper displayed on the lock screen page, dynamically rotating from the original system direction (the display direction of the screen-off page) to the current system direction, so that the screen-off wallpaper displayed on the screen-off page and the live wallpaper displayed on the lock screen page can be visually in continuity with each other, and a direction of the home screen wallpaper displayed on the home screen is the same as a direction (the current system direction) obtained when the live wallpaper display on the lock screen page ends. In this way, when the screen of the electronic device is unlocked, even if a direction of an always-on display wallpaper is inconsistent with the current system direction, the animations of the always-on display, the lock screen display, and the home screen display of the electronic device can be associatively displayed, which further improves the use experience of the user.

With reference to the third aspect, in an implementation, the method further includes: when it is determined that the electronic device does not need to display the live wallpaper based on the system direction, displaying the live wallpaper on the lock screen page of the electronic device in a portrait orientation.

In embodiments of this application, when the electronic device does not need to display the live wallpaper based on the system direction, the electronic device displays the live wallpaper in the portrait orientation by default, and both the home screen display and the always-on display of the electronic device are in a portrait orientation that is the same as a direction of the lock screen display. In this way, when the live wallpaper is the super wallpaper theme, the animations of the always-on display, the lock screen display, and the home screen display of the electronic device can alternatively be associatively displayed, and a plurality of requirements of the user can be met.

According to a fourth aspect, a live wallpaper display apparatus is provided, where the apparatus includes: a receiving module, configured to receive a notification of locking a screen of an electronic device; a first display module, configured to display a live wallpaper on a lock screen page based on a current system direction of the electronic device; and a second display module, configured to perform always-on display on a screen-off page based on the current system direction of the electronic device.

Optionally, the apparatus further includes a determining module, configured to: when a screen of the electronic device is locked, determine whether the electronic device needs to display super wallpaper animation based on the system direction; and when determining that the live wallpaper needs to be displayed based on the system direction, display the live wallpaper on the lock screen page based on the current system direction of the electronic device.

Optionally, the apparatus further includes an obtaining module, and the obtaining module is configured to obtain the current system direction of the electronic device.

That the obtaining module obtains the current system direction of the electronic device may be obtaining, by the obtaining module, the current system direction of the electronic device based on a current device posture of the electronic device, or may be described as obtaining, by the obtaining module, the current system direction of the electronic device based on a body direction of the electronic device. For example, when the body direction of the electronic device is a horizontal direction or a near-horizontal direction, the system direction of the electronic device is perpendicular to the body direction of the electronic device and is upward along the screen. When the body direction of the electronic device is a vertical direction or a near-vertical direction, the system direction of the electronic device is parallel to the body direction of the electronic device and is upward along the screen.

In embodiments of this application, for a problem that a live wallpaper theme can only be displayed in a portrait orientation and cannot be displayed in different system directions of the electronic device in the conventional technology, the live wallpaper display control apparatus that can display the live wallpaper theme in different directions of the electronic device based on the system direction is provided. When the screen of the electronic device is turned off, the lock screen page can display the live wallpaper based on the current system direction, and always-on display in different system directions can be implemented based on stored display locations and display resources, so that visual experience of a user can be improved. In addition, when the live wallpaper is a super wallpaper theme, home screen display, lock screen display, and the always-on display can end up achieving live wallpaper animation effects associatively in different system directions of the electronic device, which further improves use experience of the user.

With reference to the fourth aspect, in an implementation, the first display module is further configured to: when the electronic device is in a lock screen page display state, and the current system direction of the electronic device changes, display, on the lock screen page, animation of the live wallpaper dynamically rotating from an original system direction of the electronic device to the current system direction of the electronic device.

With reference to the fourth aspect, in an implementation, the apparatus further includes: a storage module, configured to: when an always-on display style is used, store display resources in a first system direction and a second system direction; and a processing module, configured to obtain display resources in a third system direction and a fourth system direction based on the display resources in the first system direction and the second system direction. In addition, the second display module is configured to perform the always-on display on the screen-off page based on the current system direction of the electronic device and a display resource in the current system direction. System directions include the first system direction, the second system direction, the third system direction, and the fourth system direction. When the electronic device is placed vertically, the first system direction and the third system direction are perpendicular to the left side of the electronic device, and form an included angle of 180° on a plane on which the screen of the electronic device is located. The second system direction and the fourth system direction are perpendicular to the upper side of the electronic device, and form an included angle of 180° on the plane on which the screen of the electronic device is located.

The processing module performs byte reversal on the display resources (for example, the bitmap resources) in the first system direction and the second system direction, to obtain the display resources in the third system direction and the fourth system direction, thereby implementing the always-on display in different system directions.

Optionally, the bitmap is stored in AGRB_4444 and RGB565 formats, two bytes represent one pixel, and bitmap reversal is implemented by reversing a byte sequence (that is, reordering bytes).

With reference to the fourth aspect, in an implementation, the processing module is further configured to: calculate shift information in the current system direction relative to the screen based on a ratio of a screen height in the current system direction of the electronic device to a screen height in an original system direction. The second display module is further configured to perform the always-on display based on the current system direction and the shift information.

The shift information includes one or more of a top margin, a shift range, and a shift distance, and may further include other information. This is not limited in this application. It should be understood that the shift information provides a shiftable area for pixel shift for screen burn-in protection of the always-on display of the electronic device, and always-on display content adaptively shifts in the shiftable area when the display direction does not change relative to the screen.

In addition, an interval at which the shift occurs is not limited in this application. The shift may be performed at any equal intervals, or may be performed at any unequal intervals.

In embodiments of this application, for the always-on display in different system directions, a fixed initial location, shift range, and shift distance are no longer used. Instead, the proper shift information is adaptively calculated by using the height in the current screen direction, and the always-on display and pixel shift for screen burn-in protection in different system directions are implemented based on the shift information, so that screen burn-in can be prevented more effectively, and a service life of the electronic device is prolonged.

With reference to the fourth aspect, in an implementation, the receiving module is further configured to receive a notification of unlocking the electronic device. The first display module is further configured to display the live wallpaper on the lock screen page based on the current system direction of the electronic device. In addition, the apparatus further includes a third display module, configured to display a home screen wallpaper on the home screen based on the current system direction of the electronic device.

The home screen wallpaper may be understood as an unlocking wallpaper.

Optionally, when the electronic device is unlocked, if the current system direction of the electronic device is different from a display direction of the screen-off page, the first display module is further configured to display, on the lock screen page, pictures of the live wallpaper dynamically rotating from the display direction of the screen-off page to the current system direction.

Optionally, the first display module is further configured to: when the foldable screen device is in an unfolded state, display the live wallpaper on the lock screen page based on a current system direction of the foldable screen device, where the unfolded state includes a fully unfolded state and/or a partially unfolded state.

In embodiments of this application, when the electronic device is the foldable screen device, the foldable screen device can determine, based on whether the foldable screen device is in the unfolded state, whether the live wallpaper and the screen-off wallpaper need to be displayed based on the system direction. When the foldable screen device is in the unfolded state, by default, the live wallpaper and the screen-off wallpaper need to be displayed based on the system direction. This can meet different requirements of the user when the user uses the foldable screen device in different statuses, and can further improve the use experience of the user.

With reference to the fourth aspect, in an implementation, the first display module is further configured to: when it is determined that the electronic device does not need to display the live wallpaper based on the system direction, display the live wallpaper on the lock screen page in a portrait orientation.

The pressure sensor 180A is configured to sense a pressure signal, and can convert the pressure signal into an electrical signal. In some embodiments, the pressure sensor 180A may be disposed on the display 194. There are a plurality of types of pressure sensors 180A, for example, a resistive pressure sensor, an inductive pressure sensor, and a capacitive pressure sensor. The capacitive pressure sensor may include at least two parallel plates made of conductive materials. When a force is applied to the pressure sensor 180A, capacitance between electrodes changes. The electronic device 100 determines pressure strength based on the change in the capacitance. When a touch operation is performed on the display 194, the electronic device 100 detects strength of the touch operation by using the pressure sensor 180A. The electronic device 100 may also calculate a touch location based on a detection signal of the pressure sensor 180A. In some embodiments, touch operations that are performed in a same touch location but have different touch operation strength may correspond to different operation instructions. For example, when a touch operation whose touch operation strength is less than a first pressure threshold is performed on an SMS message application icon, an instruction for viewing an SMS message is performed. When a touch operation whose touch operation strength is greater than or equal to the first pressure threshold is performed on the SMS message application icon, an instruction for creating an SMS message is performed.

The gyroscope sensor 180B may be configured to implement image stabilization during photographing. For example, when the shutter is pressed, the gyroscope sensor 180B detects an angle at which the electronic device 100 jitters, calculates, based on the angle, a distance for which a lens module needs to compensate, and allows the lens to cancel the jitter of the electronic device 100 through reverse motion, to implement image stabilization. The gyroscope sensor 180B may be further used in a navigation scenario and a motion-sensing game scenario.

The barometric pressure sensor 180C is configured to measure barometric pressure. In some embodiments, the electronic device 100 calculates an altitude by using a barometric pressure value measured by the barometric pressure sensor 180C, to assist in positioning and navigation.

The electronic device 100 detects infrared reflected light from a nearby object by using the photodiode. When sufficient reflected light is detected, it may be determined that there is an object near the electronic device 100. When insufficient reflected light is detected, the electronic device 100 may determine that there is no object near the electronic device 100. The electronic device 100 may detect, by using the optical proximity sensor 180G, that the user holds the electronic device 100 close to an ear for a call, to automatically turn off a screen for power saving. The optical proximity sensor 180G may also be used in a smart cover mode or a pocket mode to automatically unlock or lock the screen.

The ambient optical sensor 180L is configured to sense ambient light brightness. The electronic device 100 may adaptively adjust brightness of the display 194 based on the sensed ambient light brightness. The ambient optical sensor 180L may also be configured to automatically adjust white balance during photographing.

In some embodiments, the electronic device 100 executes a temperature processing policy by using the temperature detected by the temperature sensor 180J. For example, when the temperature reported by the temperature sensor 180J exceeds a threshold, the electronic device 100 lowers performance of a processor nearby the temperature sensor 180J, to reduce power consumption for thermal protection. In some other embodiments, when the temperature is less than another threshold, the electronic device 100 heats the battery 142 to prevent the electronic device 100 from being shut down abnormally due to a low temperature. In some other embodiments, when the temperature is lower than still another threshold, the electronic device 100 boosts an output voltage of the battery 142 to avoid abnormal shutdown caused by a low temperature.

For example, touch operations performed on different applications (for example, photographing and audio playing) may correspond to different vibration feedback effect. The motor 191 may also correspond to different vibration feedback effect for touch operations performed on different areas of the display 194. Different application scenarios (for example, a time reminder, information receiving, an alarm clock, a game) may also correspond to different vibration feedback effect. Touch vibration feedback effect may be further customized.

The indicator 192 may be an indicator light, and may indicate a charging status and a power change, or may indicate a message, a missed call, a notification, and the like.

The SIM card interface 195 is configured to connect to a SIM card.

The electronic device 100 interacts with a network by using the SIM card, to implement functions such as calling and data communication. In some embodiments, the electronic device 100 uses an embedded SIM (eSIM) card, that is, an embedded SIM card. The eSIM card may be embedded into the electronic device 100, and cannot be separated from the electronic device 100.

The resource manager provides various resources such as a localized character string, an icon, a picture, a layout file, and a video file for an application.

The notification manager enables an application to display notification information in a status bar, and may be configured to convey a notification message. The notification manager may automatically disappear as a short pop-up without requiring a user interaction. For example, the notification manager is configured to notify download completion, provide a message notification, and the like. The notification manager may alternatively be a notification that appears in a top status bar of the system in a form of a graph or a scroll bar text, for example, a notification of an application running on the background or a notification that appears on a screen in a form of a dialog window. For example, text information is displayed in the status bar, an alert sound is played, the electronic device vibrates, or the indicator light blinks.

The kernel layer is a layer between hardware and software. The kernel layer includes at least a display driver, a camera driver, an audio driver, and a sensor driver.

It should be understood that the technical solutions in embodiments of this application may be applied to systems such as Android, IOS, and HarmonyOS.

The technical solutions in embodiments of this application may be applied to an electronic device that has a screen and a lock screen function. For example, the method may be applied to a large-screen terminal device like a foldable screen device or a tablet computer. A main application scenario may be implementing, on the large-screen terminal device, screen-on/off animation display in different directions and always-on display in different directions. Different directions are different directions of a display picture on a display of the terminal device relative to the display.

The electronic device in embodiments of this application may be a television, a desktop computer, or a notebook computer; may be a portable electronic device like a mobile phone, a tablet computer, a camera, a video camera, or a video recorder; or may be another electronic device having a screen display function, an electronic device in a 5G network, an electronic device in a future evolved public land mobile network (PLMN), or the like. This is not limited in this application.

Currently, for example, a live wallpaper is a super wallpaper theme. An application scope of the super wallpaper theme includes a desktop, a lock screen page, and a screen-off page of the electronic device. Associative animation of the super wallpaper theme is displayed by the lock screen page of the electronic device. The lock screen page plays associative animation of the super wallpaper theme in a form of live wallpaper. The associative animation, and home screen display content and always-on display content that are of the electronic device are in a same theme, and pictures are in continuity with each other. Further, animations of the three scenarios, home screen display, lock screen display, and always-on display, of the electronic device can be associatively displayed.

However, in the conventional technology, the super wallpaper theme supports only a portrait orientation on an electronic device, and super wallpaper animation display in different directions is not supported. The super wallpaper theme cannot be adapted to an electronic device (for example, a foldable screen device or a tablet computer) that supports display in different directions. In addition, the always-on display in different directions of the electronic device is not supported, and a same direction cannot be maintained for a lock screen application and a home screen application on the electronic device (the foldable screen device, the tablet computer, or the like) that supports the display in different directions. As a result, the associative animation of the super wallpaper theme cannot be displayed.

In view of this, this application provides a live wallpaper display control method and apparatus, and an electronic device. The method can implement live wallpaper display in different system directions and always-on display in different system directions, so that a display direction of a live wallpaper on a lock screen page can be the same as a display direction (a current system direction) of a home screen, and an always-on display direction can be the same as the display direction of the live wallpaper on the lock screen page. This can conform to visual inertia of a user. In addition, when the live wallpaper is a super wallpaper theme, animations of home screen display, lock screen display, and the always-on display of the electronic device can be further associatively displayed, which further improves use experience of the user.

Terms used in the following embodiments are merely intended to describe particular embodiments, but are not intended to limit this application. The singular expression “one”, “a/an”, “said”, “the foregoing”, “the” and “this” as used in this specification and the appended claims of this application are also intended to include expressions such as “one or more”, unless otherwise specified in the context clearly. It should be further understood that, in the following embodiments of this application, “at least one” or “one or more” means one, two, or more. The term “and/or” is used to describe an association relationship between associated objects and represents that three relationships may exist. For example, A and/or B may represent the following three cases: Only A exists, both A and B exist, and only B exists, where A and B may be singular or plural. The character “/” generally indicates an “or” relationship between the associated objects.

Reference to “an embodiment”, “some embodiments”, or the like described in this specification means that one or more embodiments of this application include a feature, structure, or characteristic described with reference to the embodiments herein. Therefore, statements such as “in an embodiment”, “in some embodiments”, “in some other embodiments”, and “in other embodiments”, that appear at different places in this specification do not necessarily mean referring to a same embodiment, instead, they mean “one or more but not all of the embodiments”, unless otherwise emphasized. The terms “include”, “contain”, “have”, and their variants all mean “include but are not limited to”, unless otherwise emphasized.

To better understand the solutions in this application, the following first describes related terms in embodiments of this application.

1. Home Screen Display, Lock Screen Display, and Always-on Display of an Electronic Device

When a user performs a lock screen operation on the electronic device when the electronic device is in an application screen or a main screen, a display of the electronic device sequentially presents pictures of the home screen display, the lock screen display, and the always-on display. A lock screen application and a screen-off application of the electronic device are bound together. When the lock screen operation is performed on the electronic device, the display of the electronic device automatically enters an always-on display page after displaying a lock screen picture.

Similarly, when the user performs an unlocking operation on the electronic device when the electronic device is in an always-on display state or a screen-off state, the display of the electronic device sequentially presents pictures of the always-on display, the lock screen display (which may also be considered as unlocking display), and the home screen display. The lock screen application and the screen-off application of the electronic device are bound together. When the unlocking operation is performed on the electronic device, the display of the electronic device automatically enters a lock screen display page after displaying a screen-off picture.

2. Super Wallpaper

The super wallpaper indicates streamlining always-on display, lock screen display, and home screen display, which have been independent from each other when a display of an electronic device is turned on or off, into a whole, and sharing one wallpaper theme, to achieve associative effect of the always-on display, the lock screen display, and the home screen display for display pictures. A lock screen page displays animation of a super wallpaper theme. For example, in the conventional technology, real models such as Mars and Earth are reconstructed, and the models are made into live wallpapers. In addition, after a dark mode is enabled, the reconstructed models also enter a night mode. When the super wallpaper made based on the foregoing description is applied to the electronic device, the home screen display, the lock screen display, and the always-on display of the electronic device can jointly present the foregoing models completely and coherently, and the lock screen page presents the live wallpaper that is made based on the foregoing models. Therefore, the application of the super wallpaper can make lock screen and unlocking experience of the electronic device more consistent with visual inertia of a user, thereby enhancing use experience of the user.

It should be noted that the electronic device described in embodiments of this application is any electronic device, for example, a device like a smartphone, a tablet computer, or a smartwatch, that has a display and that can perform the lock screen or unlocking operation.

For example, FIG. 3 (a), FIG. 3 (b), and FIG. 3 (c) are a diagram of an interface for displaying a live wallpaper in the conventional technology according to an embodiment of this application.

As shown in FIG. 3 (a), FIG. 3 (b), and FIG. 3 (c), an electronic device 300 uses a live wallpaper theme, and the electronic device 300 is in a landscape mode (that is, a current system direction is a landscape orientation). A direction of a home screen wallpaper is consistent with the current system direction, that is, a landscape orientation. When a user performs a lock screen operation on the electronic device 300, a display interface of the electronic device 300 changes from home screen display (as shown in FIG. 3 (a)) to lock screen display (as shown in FIG. 3 (b)). In this case, a lock screen page displays a live wallpaper, and a display direction of live wallpaper animation on the lock screen page is a portrait orientation that is different from the current system direction. After the live wallpaper display on the lock screen page ends, the display interface of the electronic device 300 changes from the lock screen display (as shown in FIG. 3 (b)) to always-on display (as shown in FIG. 3 (c)). However, a direction of a screen-off wallpaper displayed on a screen-off page is also the portrait orientation that is different from the current system direction.

Therefore, when the electronic device (for example, a tablet computer or a foldable screen device) is in a landscape orientation state or an unfolded-state display state, and the live wallpaper theme is used, the landscape orientation of the lock screen page and the screen-off page of the electronic device cannot be implemented in the conventional technology. Further, a display direction cannot be adaptively adjusted based on the current system direction. As a result, when a screen of the electronic device is locked, an abrupt display direction change between the home screen display and the lock screen display may bring poor visual experience to the user. In addition, when the live wallpaper theme is a super wallpaper theme, super wallpaper theme pictures may be split, and visual continuity of the user is damaged. Therefore, when the electronic device uses the super wallpaper theme, associative effect of the home screen display, the lock screen display, and the always-on display of the electronic device cannot be achieved, and use experience of the user is affected.

For example, for the foregoing technical problem, FIG. 4 (a), FIG. 4 (b), and FIG. 4 (c) are a diagram of an interface for displaying a live wallpaper according to an embodiment of this application.

As shown in FIG. 4 (a), FIG. 4 (b), and FIG. 4 (c), an electronic device 400 uses a live wallpaper theme, and the electronic device 400 is in a landscape mode (that is, a current system direction is a landscape orientation). A direction of a home screen wallpaper is consistent with the current system direction, that is, a landscape orientation. When a user performs a lock screen operation on the electronic device 400, a display interface of the electronic device 400 changes from home screen display (as shown in FIG. 4 (a)) to lock screen display (as shown in FIG. 4 (b)). In this case, a lock screen page displays a live wallpaper, and a display direction of live wallpaper animation on the lock screen page is consistent with the current system direction, and is also the landscape orientation. After the live wallpaper display on the lock screen page ends, the display interface of the electronic device 400 changes from the lock screen display (as shown in FIG. 4 (b)) to always-on display (as shown in FIG. 4 (c)). A direction of a screen-off wallpaper displayed on a screen-off page is also consistent with the current system direction, that is, the landscape orientation.

In other words, in the solutions according to embodiments of this application, when the user performs the lock screen operation on the electronic device, the direction of the live wallpaper displayed on the lock screen display page, the direction of the home screen wallpaper before the screen is locked, and the direction of the screen-off wallpaper displayed on the screen-off page are all consistent with the current system direction. This conforms to visual inertia of the user and has visual continuity.

It should be understood that the current system direction described in embodiments of this application is not a fixed direction, but changes with a current device posture of the electronic device.

Similarly, in another live wallpaper display scenario, the electronic device 400 uses the live wallpaper theme, and the electronic device 400 is in a portrait mode (that is, the current system direction is a portrait orientation). The display direction of the home screen wallpaper is consistent with the current system direction, and is the portrait orientation. When the user performs the lock screen operation on the electronic device 400, both the direction of the live wallpaper displayed on the lock screen page and the direction of the screen-off wallpaper displayed on the screen-off page are consistent with the current system direction, that is a portrait orientation.

Optionally, the screen of the electronic device 400 may be locked in any one of the following operation manners: touching a power button, tapping a lock screen button in a shortcut button area in a swipe-down notification panel, setting a fixed period to perform automatic screen lock, and performing the lock screen operation according to a voice lock screen instruction. In addition, the lock screen operation may be performed in another manner. This is not limited in this application.

It should be understood that whether a display status of the electronic device in embodiments of this application is in the portrait orientation or the landscape orientation is determined based on the current device posture of the electronic device. For example, when an included angle between a near-ground side of the electronic device and a horizontal plane is less than or equal to 45°, and the near-ground side is a short side, the electronic device performs display in the portrait orientation. When the included angle between the near-ground side of the electronic device and the horizontal plane is less than or equal to 45°, and the near-ground side is a long side, the electronic device performs display in the landscape orientation. In addition, there may be another determining manner. This is not limited in this application.

It should be understood that embodiments of this application are merely example description provided for better understanding of the solutions of this application, and constitute no limitation on this application in any form.

In embodiments of this application, when the electronic device uses the live wallpaper, the live wallpaper and the screen-off page wallpaper can be displayed in different directions of a display, so that both an always-on display direction and a lock screen display direction are consistent with the current system direction. When a screen-off operation is performed on the electronic device system, the lock screen page plays a live wallpaper picture based on the current system direction, and the screen-off page also performs always-on display based on the current system direction. This can conform to the visual inertia of the user. In addition, when the live wallpaper is a super wallpaper theme, animations of the home screen display, the lock screen display, and the always-on display of the electronic device can be further associatively displayed, which further improves use experience of the user.

Optionally, for example, FIG. 5 is a diagram of an interface on which a user sets a rotation enabling function according to an embodiment of this application. As shown in FIG. 5, an example in which an electronic device is a mobile phone is used. The user may enable a screen rotation function of the electronic device by tapping an auto-rotation icon on a notification panel of the mobile phone.

Optionally, it may also be described as: The electronic device first receives a user setting operation; and enables a first function in response to the setting operation. The first function includes a function of changing a display direction of a live wallpaper with rotation of a body of the electronic device.

The user setting operation may be enabling a screen auto-rotation function on the notification panel of the electronic device; may be disabling a screen direction locking function on the notification panel of the electronic device; or may be another operation that can enable the first function. This is not limited in this application.

The following uses an example in which a live wallpaper theme is a super wallpaper theme. For example, FIG. 6 (a), FIG. 6 (b), FIG. 6 (c), FIG. 6 (d), and FIG. 6 (e) are a diagram of an interface for displaying a super wallpaper theme according to an embodiment of this application.

As shown in FIG. 6 (a), FIG. 6 (b), FIG. 6 (c), FIG. 6 (d), and FIG. 6 (e), an electronic device 600 uses the super wallpaper theme, and the electronic device 600 is in a landscape mode (that is, a current system direction is a landscape orientation). A direction of a home screen wallpaper is consistent with the current system direction (as shown in FIG. 6 (a)), that is, a landscape orientation. When a user switches the current system direction of the electronic device 600 to a portrait orientation by changing a device posture of the electronic device (for example, the user directly faces the electronic device 600, and rotates a screen of the electronic device 600 clockwise by) 90°, the display direction of the home screen wallpaper of the electronic device 600 rotates from an original system direction to the current system direction (as shown in FIG. 6 (b)). When the user continues to perform a lock screen operation on the electronic device 600, a display interface of the electronic device 600 changes from home screen display to lock screen display (as shown in FIG. 6 (c)). In this case, a lock screen page displays super wallpaper animation, and a display direction of the super wallpaper animation on the lock screen page is consistent with the current system direction, and is the portrait orientation. When the user switches the current system direction of the electronic device 600 to the landscape orientation by changing the device posture of the electronic device (for example, the user directly faces the electronic device 600, and rotates the screen of the electronic device 600 counterclockwise by) 90° in a play process of the super wallpaper animation on the lock screen page, the displayed super wallpaper animation dynamically rotates from the original system direction (which herein refers to the portrait orientation) to the current system direction (which herein refers to the landscape orientation) (as shown in FIG. 6 (d)). After the super wallpaper animation display on the lock screen page ends, the display interface of the electronic device 600 changes from the lock screen display to always-on display (as shown in FIG. 6 (e)). A direction of a screen-off wallpaper displayed on a screen-off page is also consistent with the current system direction, that is, the landscape orientation.

According to the embodiment shown in FIG. 6 (a), FIG. 6 (b), FIG. 6 (c), FIG. 6 (d), and FIG. 6 (e), for example, FIG. 7 (a), FIG. 7 (b), FIG. 7 (c), FIG. 7 (d), and FIG. 7 (e) are a diagram of still another interface for displaying a super wallpaper theme according to an embodiment of this application.

As shown in FIG. 7 (a), FIG. 7 (b), FIG. 7 (c), FIG. 7 (d), and FIG. 7 (e), an electronic device 700 uses the super wallpaper theme, and the electronic device 700 is in a portrait mode (that is, a current system direction is a portrait orientation). A direction of a home screen wallpaper is consistent with the current system direction (as shown in FIG. 7 (a)), that is, a portrait orientation. When a user performs a lock screen operation on the electronic device 700, a display interface of the electronic device 700 changes from home screen display to lock screen display (as shown in FIG. 7 (b)). In this case, a lock screen page displays super wallpaper animation, and a display direction of the super wallpaper animation on the lock screen page is consistent with the current system direction, and is the portrait orientation. When the user switches the current system direction of the electronic device 700 to a landscape orientation by changing a device posture of the electronic device in a play process of the super wallpaper animation on the lock screen page (for example, the user directly faces the electronic device 700, and rotates a screen of the electronic device 700 counterclockwise by) 90°, the displayed super wallpaper animation dynamically rotates from an original system direction (which herein refers to the portrait orientation) to the current system direction (which herein refers to the landscape orientation) (as shown in FIG. 7 (c)). On this basis, when the user switches the current system direction of the electronic device 700 to a direction opposite to the direction shown in FIG. 7 (c) by changing the device posture of the electronic device for another time (for example, the user directly faces the electronic device 700, and rotates the screen of the electronic device 700 clockwise by 180°), the displayed super wallpaper animation dynamically rotates from the original system direction (which herein refers to the direction shown in FIG. 7 (c)) to the current system direction (which herein refers to the direction opposite to the direction shown in FIG. 7 (c)) (as shown in FIG. 7 (d)). After the super wallpaper animation display on the lock screen page ends, the display interface of the electronic device 700 changes from the lock screen display to always-on display (as shown in FIG. 7 (e)). A direction of a screen-off wallpaper displayed on a screen-off page is also consistent with the current system direction (which herein refers to the direction shown in FIG. 7 (d)).

In embodiments of this application, after the electronic device uses a live wallpaper theme, in a lock screen process of the electronic device, when the current system direction of the electronic device changes in a play process of live wallpaper animation on the lock screen page, the played live wallpaper animation correspondingly and dynamically rotates from the original system direction (a system direction that does not change yet) to the current system direction, and a display direction of the screen-off page that is immediately entered is also the same as the current system direction (a system direction obtained when the lock screen display ends) of the electronic device. In this way, even if the user changes the current system direction of the electronic device in the lock screen process, effect of playing the live wallpaper is not affected. When the live wallpaper is the super wallpaper theme, animations of the home screen display, the lock screen display, and the always-on display of the electronic device can be associatively displayed, which further improves use experience of the user.

For example, FIG. 8 (a), FIG. 8 (b), FIG. 8 (c), FIG. 8 (d), FIG. 8 (e), and FIG. 8 (f) are a diagram of yet another interface for displaying a super wallpaper theme according to an embodiment of this application.

As shown in FIG. 8 (a), FIG. 8 (b), FIG. 8 (c), FIG. 8 (d), FIG. 8 (e), and FIG. 8 (f), the electronic device is a foldable screen device 800. The foldable screen device 800 has two states: a folded state and an unfolded state. The unfolded state of the foldable screen device 800 is divided into a first unfolded state and a second unfolded state. Screen display directions in the first unfolded state and the second unfolded state are perpendicular to each other.

The foldable screen device 800 uses the super wallpaper theme, and the foldable screen device 800 is in the first unfolded state. A current system direction is a direction that is from a side A to a side D and that is perpendicular to the side A, and a direction of a home screen wallpaper is consistent with the current system direction (as shown in FIG. 8 (a)). When a user performs a folding operation on the foldable screen device 800, to enable the state of the foldable screen device 800 to switch from the first unfolded state to the folded state, the current system direction does not change, but the display direction of the home screen of the foldable screen device 800 changes to a direction that is from a side B to a side C and that is perpendicular to the side B (as shown in FIG. 8 (b)). When the user continues to perform a lock screen operation on the foldable screen device 800, a display interface of the foldable screen device 800 changes to lock screen display (as shown in FIG. 8 (c)). In this case, a lock screen page displays super wallpaper animation, and a display direction of the super wallpaper animation on the lock screen page is the direction that is from the side B to the side C and that is perpendicular to the side B. When the user switches the state of the foldable screen device 800 from the folded state to the first unfolded state in a play process of the super wallpaper animation on the lock screen page, the displayed super wallpaper animation dynamically rotates from an original system direction (which herein refers to the direction that is from the side B to the side C and that is perpendicular to the side B) to the current system direction (which herein refers to the direction that is from the side A to the side D and that is perpendicular to the side A) (as shown in FIG. 8 (d)). On this basis, when the user switches, by changing a device posture of the foldable screen device (for example, the user directly faces the foldable screen device 800, and rotates a screen of the foldable screen device 800 counterclockwise by) 90°, the current system direction of the foldable screen device 800 to the direction that is from the side B to the side C and that is perpendicular to the side B, the displayed super wallpaper animation dynamically rotates from the original system direction (which herein refers to the direction that is from the side A to the side D and that is perpendicular to the side A) to the current system direction (which herein refers to the direction that is from the side B to the side C and that is perpendicular to the side B) (as shown in FIG. 8 (e)). After the super wallpaper animation display on the lock screen page ends, the display interface of the foldable screen device 800 changes from the lock screen display to always-on display (as shown in FIG. 8 (f)). A direction of a screen-off wallpaper displayed on a screen-off page is also consistent with the current system direction (which herein refers to the direction that is from the side B to the side C and that is perpendicular to the side B).

It should be understood that the unfolded state of the foldable screen device may further be classified into a fully unfolded state and a partially unfolded state. In addition, when the foldable screen device is in the partially unfolded state, a display status of the screen of the foldable screen device may be the same as an actual status of the fully unfolded state, or may be the same as an actual status of the folded state.

In embodiments of this application, when the electronic device is the foldable screen device, the foldable screen device can determine, based on whether the foldable screen device is in the unfolded state, whether a live wallpaper and the screen-off wallpaper need to be displayed based on the system direction. When the foldable screen device is in the unfolded state, by default, the live wallpaper and the screen-off wallpaper need to be displayed based on the system direction. This can meet different requirements of the user when the user uses the foldable screen device in different statuses, and can further improve use experience of the user.

In parallel with the embodiment shown in FIG. 4 (a), FIG. 4 (b), and FIG. 4 (c), for example, FIG. 9 (a), FIG. 9 (b), and FIG. 9 (c) are a diagram of still another interface for displaying a live wallpaper according to an embodiment of this application.

As shown in FIG. 9 (a), FIG. 9 (b), and FIG. 9 (c), an electronic device 900 uses a live wallpaper theme, and the electronic device 900 is in a landscape mode (that is, a current system direction is in a landscape orientation). A display interface of the electronic device is on an always-on display page. A display direction of a screen-off wallpaper is the same as the current system direction, and is in the landscape orientation (as shown in FIG. 9 (a)). When a user performs an unlocking operation on the electronic device 900 when the current system direction does not change, the display interface of the electronic device 900 changes from always-on display to lock screen display (as shown in FIG. 9 (b)), and a direction of the live wallpaper displayed on a lock screen page is the same as the current system direction, that is, the landscape orientation, and is the same as the direction of the screen-off wallpaper displayed on the screen-off page before unlocking. After the live wallpaper display on the lock screen page ends, the display interface of the electronic device 900 changes from the lock screen display to home screen display (as shown in FIG. 9 (c)), and a direction of a home screen wallpaper displayed on a home screen is also consistent with the current system direction, that is, the landscape orientation, and is the same as the direction of the live wallpaper displayed on the lock screen page.

Optionally, the electronic device 900 may be unlocked in any one of the following operation manners: touching a power button, recognizing a fingerprint, recognizing a face, inputting a password, recognizing a gesture, or performing the unlocking operation according to a voice unlocking instruction. In addition, the unlocking operation may be performed in another manner. This is not limited in this application.

Similarly, in another live wallpaper display scenario, the electronic device 900 uses the live wallpaper theme, and the electronic device 900 is in a portrait mode (that is, the current system direction is a portrait orientation). The display interface of the electronic device 900 is on the always-on display page, and the display direction of the screen-off wallpaper is consistent with the current system direction, and is the portrait orientation. When the user performs the unlocking operation on the electronic device 900 when the current system direction does not change, both a direction of live wallpaper animation displayed on the lock screen page and a direction of the screen-off wallpaper displayed on the home screen are consistent with the current system direction, that is, a portrait orientation.

In embodiments of this application, the electronic device uses the live wallpaper. When the display interface of the electronic device is on the screen-off page, and the current system direction of the electronic device is the same as the display direction of the screen-off page, the user performs the screen unlocking operation on the electronic device when the current system direction does not change, and the display interface of the electronic device sequentially displays the screen-off wallpaper, a lock screen wallpaper (the live wallpaper), and the home screen wallpaper. In addition, display directions of the screen-off wallpaper, the lock screen wallpaper, and the home screen wallpaper are the same as the current system direction, and can conform to visual inertia of the user. In addition, when the live wallpaper is the super wallpaper theme, animations of the home screen display, the lock screen display, and the always-on display of the electronic device can be further associatively displayed, which further improves use experience of the user.

An example in which a live wallpaper theme is a super wallpaper theme is used. For example, FIG. 10 (a), FIG. 10 (b), FIG. 10 (c), and FIG. 10 (d) are a diagram of still another interface for displaying a super wallpaper according to an embodiment of this application.

As shown in FIG. 10 (a), FIG. 10 (b), FIG. 10 (c), and FIG. 10 (d), an electronic device 1000 uses a super wallpaper theme, and the electronic device 1000 is in a portrait mode. A current system direction of the electronic device 1000 is a portrait orientation, and a display interface of the electronic device 1000 is on a screen-off page. A direction of a screen-off wallpaper displayed on the screen-off page is consistent with the current system direction, that is, a portrait orientation (as shown in FIG. 10 (a)). On this basis, a user enables, by rotating the electronic device 1000, the current system direction of the electronic device 1000 to switch from the portrait orientation to a landscape orientation. In this case, the display interface of the electronic device 1000 is still on the screen-off page, and the direction of the screen-off wallpaper displayed on the screen-off page does not change relative to a display of the electronic device. The screen-off wallpaper is still displayed in the portrait orientation, and the display direction of the screen-off wallpaper does not change with the current system direction (as shown in FIG. 10 (b)). In this case, the user performs an unlocking operation on the electronic device 1000, and the display interface of the electronic device 1000 changes from always-on display (as shown in FIG. 10 (b)) to lock screen display (which may also be considered as unlocking display, as shown in FIG. 10 (c)). In this process, the user may see that there is a process of a direction, of super wallpaper animation displayed on the lock screen page, dynamically rotating from the portrait orientation to the landscape orientation, so that the screen-off wallpaper displayed on the screen-off page and the super wallpaper animation displayed on the lock screen page can be visually in continuity with each other. After the super wallpaper display on the lock screen page ends, the display interface of the electronic device 1000 changes from the lock screen display (as shown in FIG. 10 (c)) to home screen display (as shown in FIG. 10 (d)). A direction of a home screen wallpaper displayed on a home screen is the same as the current system direction, that is, is the same as a direction obtained when the super wallpaper display on the lock screen page ends, that is, the landscape orientation.

It should be understood that when the electronic device is in a screen-off state, the direction of the screen-off wallpaper displayed on the screen-off page does not change with the current system direction of the electronic device.

In embodiments of this application, the electronic device uses the super wallpaper. When a display interface of the electronic device is on the screen-off page, and the current system direction of the electronic device is different from the display direction of the screen-off page, the user performs a screen unlocking operation on the electronic device, and the display interface of the electronic device sequentially displays the screen-off wallpaper, a lock screen wallpaper (the super wallpaper animation), and the home screen wallpaper. There is a process of the direction, of the super wallpaper displayed on the lock screen page, dynamically rotating from an original system direction (the display direction of the screen-off page) to the current system direction, so that the screen-off wallpaper displayed on the screen-off page and the super wallpaper animation displayed on the lock screen page can be visually in continuity with each other, and the direction of the home screen wallpaper displayed on the home screen is the same as the direction (the current system direction) obtained when the super wallpaper display on the lock screen page ends. In this way, when the screen of the electronic device is unlocked, even if a direction of an always-on display wallpaper is inconsistent with the current system direction, animations of the always-on display, the lock screen display, and the home screen display of the electronic device can be associatively displayed, which further improves use experience of the user.

An example in which a live wallpaper theme is a super wallpaper theme is used. For example, FIG. 11 (a), FIG. 11 (b), FIG. 11 (c), and FIG. 11 (d) are a diagram of still another interface for displaying a super wallpaper theme according to an embodiment of this application.

As shown in FIG. 11 (a), FIG. 11 (b), FIG. 11 (c), and FIG. 11 (d), an electronic device 1100 uses the super wallpaper theme, and the electronic device 1100 is in a portrait mode (that is, a current system direction is a portrait orientation). An always-on display direction is consistent with the current system direction (as shown in FIG. 11 (a)), that is, a portrait orientation. When a user performs an unlocking operation on the electronic device 1100, a display interface of the electronic device 1100 changes from always-on display to lock screen display (as shown in FIG. 11 (b)). In this case, a lock screen page displays super wallpaper animation, and a display direction of the super wallpaper animation on the lock screen page is consistent with the current system direction, and is the portrait orientation. When the user switches the current system direction of the electronic device 1100 to a landscape orientation by changing a device posture of the electronic device (for example, the user directly faces the electronic device 1100, and rotates a screen of the electronic device 1100 counterclockwise by) 90° in a play process of the super wallpaper animation on the lock screen page, the displayed super wallpaper animation dynamically rotates from an original system direction (which herein refers to the portrait orientation) to the current system direction (which herein refers to the landscape orientation) (as shown in FIG. 11 (c)). After the super wallpaper animation display on the lock screen page ends, the display interface of the electronic device 1100 changes from the lock screen display to home screen display (as shown in FIG. 11 (d)). A direction of a screen-off wallpaper displayed on a screen-off page is also consistent with the current system direction, that is, the landscape orientation.

In embodiments of this application, after the electronic device uses a live wallpaper theme, in an unlocking process of the electronic device, when the current system direction of the electronic device changes in a play process of live wallpaper animation on the lock screen page, the played live wallpaper animation correspondingly and dynamically rotates from the original system direction (a system direction that does not change yet) to the current system direction, and a display direction of a home screen that is immediately entered is also the same as the current system direction (a system direction obtained when the lock screen display ends) of the electronic device. In this way, even if the user changes the current system direction of the electronic device in the unlocking process, effect of playing the live wallpaper is not affected. When the live wallpaper is the super wallpaper theme, animations of the home screen display, the lock screen display, and the always-on display of the electronic device can be associatively displayed, which further improves use experience of the user.

For example, FIG. 12 (a), FIG. 12 (b), FIG. 12 (c), FIG. 12 (d), and FIG. 12 (e) are a diagram of yet another interface for displaying a super wallpaper theme according to an embodiment of this application.

As shown in FIG. 12 (a), FIG. 12 (b), FIG. 12 (c), FIG. 12 (d), and FIG. 12 (e), the electronic device is a foldable screen device 1200. The foldable screen device 1200 has two states: a folded state and an unfolded state. The unfolded state of the foldable screen device 1200 is divided into a first unfolded state and a second unfolded state. Screen display directions in the first unfolded state and the second unfolded state are perpendicular to each other.

The foldable screen device 1200 uses the super wallpaper theme, and the foldable screen device 1200 is in the folded state. A current system direction is a direction that is from a side C to a side B and that is perpendicular to the side C, and an always-on display direction is consistent with the current system direction (as shown in FIG. 12 (a)). When a user performs an unlocking operation on the foldable screen device 1200, a display interface of the foldable screen device 1200 changes to lock screen display (as shown in FIG. 12 (b)). In this case, a lock screen page displays super wallpaper animation, and a display direction of the super wallpaper animation on the lock screen page is the direction that is from the side C to the side B and that is perpendicular to the side C. When the user performs an unfolding operation on the foldable screen device 1200 in a play process of the super wallpaper animation on the lock screen page, to enable the state of the foldable screen device 1200 to switch from the folded state to the second unfolded state, the current system direction does not change, and the display direction of the super wallpaper animation on the lock screen page is still the same as the current system direction, and is the direction that is from the side C to the side B and that is perpendicular to the side C (as shown in FIG. 12 (c)). On this basis, when the user switches, by changing a device posture of the foldable screen device (for example, the user directly faces the foldable screen device 1200, and rotates a screen of the foldable screen device 1200 counterclockwise by) 90°, the current system direction of the foldable screen device 1200 to a direction that is from the side A to a side D and that is perpendicular to the side A, the displayed super wallpaper animation dynamically rotates from an original system direction (which herein refers to the direction that is from the side C to the side B and that is perpendicular to the side C) to the current system direction (which herein refers to the direction that is from the side A to the side D and that is perpendicular to the side A) (as shown in FIG. 12 (d)). After the super wallpaper animation display on the lock screen page ends, the display interface of the foldable screen device 1200 changes from the lock screen display to home screen display (as shown in FIG. 12 (e)). A direction of a home screen wallpaper displayed on a home screen is also consistent with the current system direction (which herein refers to the direction that is from the side A to the side D and that is perpendicular to the side A).

In embodiments of this application, when the electronic device is the foldable screen device, the foldable screen device can determine, based on whether the foldable screen device is in the unfolded state, whether a live wallpaper and a screen-off wallpaper need to be displayed based on the system direction. When the foldable screen device is in the unfolded state, by default, the live wallpaper and the screen-off wallpaper need to be displayed based on the system direction. This can meet different requirements of the user when the user uses the foldable screen device in different statuses, and can further improve use experience of the user.

To better understand the super wallpaper display control method according to embodiments of this application, for example, FIG. 13 is a flowchart of a live wallpaper display control method 1300 according to an embodiment of this application. As shown in FIG. 13, the method is applied to an electronic device, the current electronic device uses a live wallpaper theme, and a screen of the electronic device is on an application screen. The method 1300 includes the following steps.

Step S1301: After a user triggers a lock screen function of the electronic device, the electronic device determines whether the current electronic device supports live wallpaper display in different directions. If no, step S1302 is performed; or if yes, step S1303 is performed.

The operation of triggering the lock screen function of the electronic device may also be referred to as a screen-off operation on the electronic device.

Optionally, step S1301 may be replaced with: After the user triggers the lock screen function of the electronic device, the electronic device determines whether the current screen needs to display a live wallpaper based on a current system direction. If no, step S1302 is performed; or if yes, step S1303 is performed. Step S1301 may be further replaced with: After the user triggers the lock screen function of the electronic device, determine whether a display of the current electronic device is a large display. If no, step S1302 is performed; or if yes, step S1303 is performed.

Step S1302: A lock screen page displays the live wallpaper in a portrait orientation.

When the electronic device does not support the live wallpaper display in different directions, it is considered by default that the electronic device supports the live wallpaper display only in the portrait orientation. Correspondingly, the lock screen page displays the live wallpaper in the portrait orientation.

Step S1303: Obtain the current system direction.

The current system direction is a system direction in which the electronic device is currently located. The current system direction is relative to the display of the electronic device, and may be classified into the portrait orientation and a landscape orientation. The portrait orientation may be classified into two opposite directions, and the landscape orientation may also be divided into two opposite directions.

For example, when an included angle between a near-ground side of the electronic device and a horizontal plane is less than or equal to 45°, and the near-ground side is a short side, the electronic device is in a portrait orientation, the current system direction is the portrait orientation, and a positive direction of a picture displayed on the display is perpendicular to the near-ground side and upward. When an included angle between a near-ground side of the electronic device and a horizontal plane is less than or equal to 45°, and the near-ground side is a long side, the electronic device is in the landscape orientation, the current system direction is the landscape orientation, and a positive direction of a picture displayed on the display is perpendicular to the near-ground side and upward. In addition, there may be another determining manner. This is not limited in this application.

Optionally, the current system direction is determined by using a current device posture of the electronic device, and may be obtained by using a posture sensor in the electronic device. The posture sensor may include a gyroscope sensor or a triaxial acceleration sensor, and may further include another sensor. This is not limited in this application.

Step S1304: The lock screen page displays the live wallpaper in the current system direction.

For example, the electronic device is the foldable phone. For example, the current system direction of the electronic device is the x-axis positive direction, that is, a home screen is in the landscape orientation. In this case, the user performs the screen-off operation on the electronic device, and the lock screen page of the electronic device displays the live wallpaper in the x-axis positive direction.

Step S1305: The display of the electronic device enters a screen-off page.

After it is determined that the electronic device supports the live wallpaper display in different directions, when an application is in always-on display, the electronic device stores display locations and display resources in different system directions. In a screen-off process, the electronic device can implement the always-on display in the current system direction based on the stored display location and display resource.

Optionally, the always-on display may be implemented by using a display controller in the electronic device.

Optionally, the live wallpaper theme may be a super wallpaper theme.

It should be understood that step S1301 in embodiments of this application is an optional step.

In embodiments of this application, for a problem that the live wallpaper theme can only be displayed in a portrait orientation and cannot be displayed in different system directions of the electronic device in the conventional technology, the live wallpaper display control method in which the live wallpaper theme can be displayed in different directions of the electronic device based on the system direction is proposed. When the screen of the electronic device is turned off, a lock screen application displays the live wallpaper based on the current system direction, and the screen-off page can implement the always-on display in different system directions based on the stored display locations and display resources, so that visual experience of the user can be improved. In addition, when the live wallpaper is the super wallpaper theme, home screen display, lock screen display, and the always-on display can end up achieving live wallpaper animation effects associatively in different system directions of the electronic device, which further improves use experience of the user.

According to the embodiment shown in FIG. 13, FIG. 14 is a flowchart of another live wallpaper display control method 1400 according to an embodiment of this application. As shown in FIG. 14, the method is applied to an electronic device, the current electronic device uses a live wallpaper theme, and a screen of the electronic device is on an application screen. The method 1400 includes the following steps.

Step S1401: When the electronic device receives a lock screen notification, determine whether the electronic device supports screen folding. If yes, step S1402 is performed; or if no, step S1406 is performed.

Whether the electronic device supports screen folding is determined by a structure and performance of the electronic device.

Step S1402: When it is determined that the electronic device supports screen folding, further determine whether the screen of the electronic device is in an unfolded state. If yes, step S1403 is performed; or if no, step S1407 is performed.

The unfolded state of the screen of the electronic device may include a fully unfolded state and/or a partially unfolded state. The fully unfolded state means that two half screens folded over each other are located on a same plane, and there is an included angle of 180° between the two half screens. The partially unfolded state may mean that the included angle between the two half screens is less than 180°, or may mean that the included angle between the two half screens is greater than or equal to 90° and less than 180°.

Step S1403: Obtain a current system direction of the electronic device.

Explanation of the current system direction of the electronic device is described in detail in step S1303. For brevity, details are not described herein again.

Step S1404: A lock screen page of the electronic device displays a live wallpaper in the current system direction.

It should be understood that if the current system direction of the electronic device changes in a process in which the lock screen page of the electronic device displays the live wallpaper, a direction of the displayed live wallpaper is also correspondingly switched from an original system direction to the current system direction through dynamic rotation.

Step S1405: A screen-off page of the electronic device is in always-on display in the current system direction.

It should be understood that the always-on display in the current system direction described in this step is different from that described in step S1404. When playing of the live wallpaper on the lock screen page of the electronic device is completed, the screen of the electronic device is switched to the always-on display. In this case, an always-on display direction is the same as a direction obtained when the playing of the live wallpaper ends, so that the live wallpaper displayed on the lock screen page and the always-on display are visually in continuity with each other. In addition, after a display interface of the electronic device is switched to the always-on display, the always-on display direction does not change with a change of the current system direction of the electronic device.

Step S1406: When it is determined that the current electronic device does not support screen folding, further determine whether the electronic device supports super wallpaper display in different directions. If yes, step S1403 is performed; or if no, step S1407 is performed.

Explanation of step S1406 has been described in detail in step S1301. For brevity, details are not described herein again.

Step S1407: The lock screen page displays the live wallpaper in a portrait orientation.

When it is determined that the electronic device does not support live wallpaper display in different directions, it is considered by default that the electronic device supports the live wallpaper display only in the portrait orientation. Correspondingly, the lock screen page displays the live wallpaper in the portrait orientation.

Step S1408: The electronic device performs always-on display in the portrait orientation.

In embodiments of this application, when the screen of the electronic device is locked, whether the electronic device is a foldable screen device is first determined. When the electronic device is the foldable screen device and the screen of the electronic device is in the unfolded state, lock screen display and always-on display are performed based on the current system direction of the electronic device. When the electronic device is not the foldable screen device, whether the electronic device supports the live wallpaper display in different directions is further determined. When the electronic device supports the live wallpaper display in different directions, lock screen display and always-on display are performed based on the current system direction of the electronic device. In this way, visual experience of a user can be improved. In addition, when the live wallpaper is a super wallpaper theme, home screen display, the lock screen display, and the always-on display can end up achieving live wallpaper animation effects associatively in different system directions of the electronic device, which further improves use experience of the user. According to the embodiment shown in FIG. 8 (a), FIG. 8 (b), FIG. 8 (c), FIG. 8 (d), FIG. 8 (e), and FIG. 8 (f), that a live wallpaper is a super wallpaper is used as an example. FIG. 15 is a flowchart of a super wallpaper display control method 1500 according to an embodiment of this application. As shown in FIG. 15, the method is applied to an electronic device, the current electronic device uses a super wallpaper theme, and a screen of the electronic device is on an always-on display page. The method 1500 includes the following steps.

Step S1501: After a user triggers a screen unlocking function of the electronic device, screen display of the current electronic device changes from the always-on display page to a lock screen display page, and the lock screen page displays super wallpaper animation in a current system direction.

For example, the electronic device is a foldable phone. Based on a natural coordinate system of the phone, system directions of the foldable phone are: an x-axis positive direction, an x-axis negative direction, a y-axis positive direction, and a y-axis negative direction. The current system direction of the electronic device is the x-axis positive direction, and a direction of screen-off page display is the y-axis positive direction. When the user unlocks the electronic device, the super wallpaper animation displayed on the lock screen page dynamically rotates from the y-axis positive direction to the x-axis positive direction in a display process, to ensure associative display effect of the screen-off page display and lock screen page display.

For another example, the electronic device is a foldable phone. Based on a natural coordinate system of the phone, system directions of the foldable phone are: an x-axis positive direction, an x-axis negative direction, a y-axis positive direction, and a y-axis negative direction. The current system direction of the electronic device is the x-axis positive direction, and a direction of screen-off page display is also the x-axis positive direction. When the user unlocks the electronic device, a direction of the super wallpaper animation displayed on the lock screen page is the x-axis positive direction, to implement associative display effect of the screen-off page display and lock screen page display.

Step S1502: A home screen displays a home screen wallpaper in the current system direction.

It should be understood that the current system direction may change in a time period between screen locking and screen unlocking of the electronic device. However, when the current system direction changes, an always-on display direction does not change accordingly, and directions of lock screen display and home screen display that sequentially appear after unlocking are consistent with the current system direction. Therefore, in this case, after the screen of the electronic device is unlocked, there is a process of the direction, of the super wallpaper animation displayed on the lock screen page, dynamically rotating from an original system direction (the always-on display direction) to the current system direction, so that the super wallpaper animation displayed on the lock screen page and a screen-off wallpaper displayed on a screen-off page can be linked up, and visual continuity is provided.

In embodiments of this application, when the user unlocks the screen of the electronic device, directions of the unlocked lock screen page and the home screen display are consistent with the current system direction. In addition, when the current system direction is inconsistent with the always-on display direction, there is the process of the direction, of the super wallpaper animation displayed on the lock screen page, dynamically rotating from the original system direction (the always-on display direction) to the current system direction, so that associative display effect of the always-on display, the lock screen display, and the home screen of the electronic device in the unlocking process can be achieved. In addition, when the super wallpaper animation is applied to the electronic device, the always-on display, the lock screen display, and the home screen wallpaper of the electronic device are a complete set of themes. The associative display effect of the always-on display, the lock screen display, and the home screen is of great significance for presentation of the super wallpaper theme, and use experience of the user can be further improved.

In parallel with the embodiment shown in FIG. 13, for example, FIG. 16 shows still another live wallpaper display method according to an embodiment of this application. The method is applied to an electronic device, and the electronic device uses a live wallpaper theme. As shown in FIG. 16, the method includes the following steps.

Step S1601: Display a screen-off wallpaper.

Step S1602: When a screen-on operation is detected, in response to successful unlocking of the electronic device, display, to an unlocking wallpaper, from animation effect of switching from the screen-off wallpaper to the unlocking wallpaper.

The unlocking wallpaper may also be referred to as a home screen wallpaper, and the screen-off wallpaper may also be considered as always-on display.

Optionally, the screen-on operation may be an unlocking operation.

Optionally, that display directions of the animation effect and the unlocking wallpaper can change with rotation of a body of the electronic device includes: if a body direction of the electronic device rotates from a vertical direction or a partially vertical direction to a horizontal direction or a partially horizontal direction, changing the display directions of the animation effect and the unlocking wallpaper from a portrait orientation to a landscape orientation.

Step S1603: When a screen-on operation is detected, in response to unsuccessful unlocking of the electronic device, display, to a lock screen wallpaper, from animation effect of switching from the screen-off wallpaper to the lock screen wallpaper.

Optionally, that display directions of the animation effect and the lock screen wallpaper can change with rotation of a body of the electronic device includes: if a body direction of the electronic device rotates from a vertical direction or a partially vertical direction to a horizontal direction or a partially horizontal direction, changing the display directions of the animation effect and the lock screen wallpaper from a portrait orientation to a landscape orientation.

Step S1604: When the screen-on operation is detected and the electronic device is on the lock screen page, in response to successful unlocking of the electronic device, display, to the unlocking wallpaper, from animation effect of switching from the lock screen wallpaper to the unlocking wallpaper.

In embodiments of this application, the unlocking operation is performed on the electronic device when the screen-off wallpaper is displayed. Even if the unlocking fails, the animation effect of switching from the screen-off wallpaper to the lock screen wallpaper is displayed, and the screen ends up as a lock screen wallpaper display page. In addition, regardless of whether the unlocking succeeds after one attempt or after a plurality of attempts, wallpaper display corresponding to the electronic device has good visual continuity. In this way, a user can obtain good visual experience.

In the conventional technology, there are dynamic styles in always-on display of an electronic device. Display resources of these dynamic styles are implemented after frames of pictures are combined for display. Because there are a large quantity of frames, a large quantity of display resources need to be stored. To avoid an efficiency problem caused by picture decoding and storage of a display resource in a corresponding direction when a screen of the electronic device is turned off, the display resources of the dynamic styles are stored when a live wallpaper theme is used, and a group of live display resources need to be stored in each system direction. Therefore, to implement always-on display of the electronic device in four system directions, display resources in the four system directions need to be stored. As a result, large storage space is occupied.

For this problem, according to the embodiment shown in FIG. 13, for example, FIG. 17 is a flowchart of an always-on display control method 1700 according to an embodiment of this application. The method 1700 can implement always-on display in four system directions by using display resources in two system directions. As shown in FIG. 17, the method 1700 includes the following steps.

Step S1701: Determine whether a current electronic device needs to adapt to always-on display in different directions. If yes, step S1702 is performed.

When an always-on display style is used to the electronic device, it is determined whether the electronic device needs to adapt to the always-on display in different system directions.

Optionally, whether the always-on display in different directions needs to be adapted may be further determined by determining whether the current electronic device supports super wallpaper display in different directions. If the current electronic device supports the super wallpaper display in different directions, it is determined that the electronic device needs to adapt to the always-on display in different directions. It may be further determined whether a current screen needs to display a super wallpaper based on a current system direction. If yes, it is determined that the electronic device needs to adapt to the always-on display in different directions. Alternatively, it may be determined whether a display of the current electronic device is a large display. If yes, it is determined that the electronic device needs to adapt to the always-on display in different directions.

It should be understood that step S1701 is an optional step.

Step S1702: Store display resources in a first direction and a second direction.

The first direction and the second direction are two of the four system directions of the electronic device. The first direction and the second direction are perpendicular to each other and are at an included angle of 90°, and respectively represent a landscape orientation and a portrait orientation of the electronic device.

Optionally, a display resource in the first direction includes a bitmap resource in the first direction, and may further include another display resource. This is not limited in this application.

Similarly, a display resource in the second direction includes a bitmap resource in the second direction, and may further include another display resource. This is not limited in this application.

Step S1703: When a user performs a screen-off operation on the electronic device, the electronic device obtains display resources in a third direction and a fourth direction based on the display resources in the first direction and the second direction.

The third direction and the first direction are positive and negative directions of each other, and the fourth direction and the second direction are positive and negative directions of each other.

For example, the electronic device is a foldable phone. Based on a natural coordinate system of the phone, system directions of the foldable phone are: an x-axis positive direction, an x-axis negative direction, a y-axis positive direction, and a y-axis negative direction. The first direction and the second direction may be the x-axis positive direction and the y-axis positive direction respectively. Correspondingly, the third direction and the fourth direction are the x-axis negative direction and the y-axis negative direction respectively.

Optionally, a display resource in the third direction includes a bitmap resource in the third direction, and may further include another display resource. This is not limited in this application.

Similarly, a display resource in the fourth direction includes a bitmap resource in the fourth direction, and may further include another display resource. This is not limited in this application.

Optionally, the bitmap is stored in AGRB_4444 and RGB565 formats, two bytes represent one pixel, and bitmap reversal is implemented by reversing a byte sequence (that is, reordering bytes).

Step S1704: Perform always-on display in the current system direction.

The current system direction is determined by the electronic device based on a current device posture of the electronic device, and is one of the first direction to the fourth direction.

Optionally, the device posture of the electronic device may be represented by an orientation of the display on a body of the electronic device and an included angle between the body of the electronic device and the ground. For example, the display of the electronic device may face due south, and the body and the ground form an included angle of 45°.

In correspondence with the embodiment shown in FIG. 17, FIG. 18 is a diagram of an always-on display interface in different system directions according to an embodiment of this application. As shown in FIG. 18, when a user uses an always-on display style on an electronic device, and the user performs a screen-off operation on the electronic device, the electronic device obtains display resources in a third system direction and a fourth system direction based on display resources in a first system direction and a second system direction. In this way, the display resources in the four system directions are obtained, and always-on display in the four system directions is implemented.

The display resources in the first system direction and the second system direction are stored by the electronic device when the always-on display style is used.

Descriptions of the first system direction to the fourth system direction have been described in detail in the embodiment shown in FIG. 16. For brevity, details are not described herein again.

For always-on display in different directions, not only a displayed picture resource needs to be rotated, but also a display location needs to be rotated. Different layers have different rotation manners due to different relative locations.

It should be understood that a time display location on a display screen of the electronic device is a relative location in a base diagram, and a display location of another picture is an absolute location on the screen.

For example, with reference to FIG. 19 (a) and FIG. 19 (b), absolute location coordinate transformation and relative location coordinate transformation of an image displayed on the display screen of the electronic device are described.

FIG. 19 (a) is a diagram of always-on display (picture) when the screen of the electronic device rotates counterclockwise by 90°. A height and a width of the always-on display picture in a current system direction are known, and a screen width and a screen height in a first direction are known. In this case, a coordinate location of current always-on display can be calculated based on a current system direction coordinate system. A calculation process is as follows:

Always-on display coordinates in an original system direction are denoted as (L, T, R, B), and always-on display coordinates in the current system direction are denoted as (L1, T1, R1, B1).

Then, L1=screen height-B; T2=(screen width-picture width)/2; R1=L+picture height; and B1=T+picture width.

In this way, coordinates of an absolute location, on the screen, of a display location of the always-on display picture can be transformed.

FIG. 19 (b) is a diagram of always-on display (time) when the screen of the electronic device rotates clockwise by 90°. A system direction is switched from the second direction to the third direction. A screen height (base height) and a screen width (base width) in the second direction are known, and a to-be-calculated width and height of a digit are known. In this case, a coordinate location, in the base diagram, of clock digits in current always-on display can be calculated based on a current system direction coordinate system. A calculation process is as follows:

Always-on display coordinates in an original system direction are denoted as (L2, T2, R2, B2), and always-on display coordinates in the current system direction are denoted as (L3, T3, R3, B3).

Then, L3=base height−T2−digit height; T3=base width−L2−digit width (screen width−picture width); R3=L2+digit height; and B3=T+digit width.

In this way, coordinates of the relative coordinate location, in the base diagram, of the clock digits in the always-on display can be transformed.

In the conventional technology, in always-on display in a single system direction, the always-on display completes corresponding pixel shift for screen burn-in protection based on a fixed initial location, shift range, and shift distance, thereby avoiding a case in which a screen that is always-on affects a service life of an electronic device. However, always-on display, of the screen of the electronic device, in different system directions uses the fixed initial location, shift range, and shift distance, and cannot adapt to screen heights in different system directions.

For this problem, for example, FIG. 20 is a flowchart of another always-on display control method 2000 according to an embodiment of this application. As shown in FIG. 20, the method 2000 includes the following steps.

Step S2001: Calculate shift information in a current system direction relative to a screen based on a ratio of a screen height in the current system direction to a screen height in an original system direction.

The shift information includes one or more of a top margin, a shift range, and a shift distance. In addition, the shift information may further include other information. This is not limited in this application.

For example, the system direction of an electronic device is switched from a landscape orientation to a portrait orientation, that is, the original system direction is the landscape orientation, and the current system direction is the portrait orientation. It is assumed that the screen height in the current system direction is 2, the screen height in the original system direction is 1, and the ratio of the screen height in the current system direction to the screen height in the original system direction is 2:1. A ratio of a top margin in the current system direction to a top margin in the original system direction is equal to 2:1, a ratio of a shift range in the current system direction to a shift range in the original system direction is equal to 2:1, and a ratio of a shift distance in the current system direction to a shift distance in the original system direction is equal to 2:1.

Optionally, when the electronic device is switched from the portrait orientation to the landscape orientation, the shift information may be calculated according to this formula: (fixed distance/portrait screen height)×current screen height. The fixed distance is associated with a screen size of the electronic device, and may be a value, or may be a value range.

Step S2002: Perform pixel shift for screen burn-in protection based on the shift information.

Screen burn-in means that after a screen displays a still image for long time, a ghost image of the image is left at a display location. This ghost image is permanent and cannot be eliminated, and usually appears on plasma televisions and mobile phones with organic light-emitting diode (OLED) screens. The pixel shift for screen burn-in protection refers to shift of an image displayed on a display, to prevent an image from being displayed in a same pixel or a same pixel area for long time, thereby implementing a screen burn-in protection function.

It should be understood that the shift information provides a shiftable area for pixel shift for screen burn-in protection of always-on display of the electronic device, and always-on display content adaptively shifts in the shiftable area when a display direction does not change relative to the screen.

In addition, an interval at which the shift occurs is not limited in this application. The shift may be performed at any equal intervals, or may be performed at any unequal intervals.

In embodiments of this application, for always-on display in different system directions, a fixed initial location, shift range, and shift distance are no longer used. Instead, the proper shift information is adaptively calculated by using a height in a current screen direction, and the always-on display and pixel shift for screen burn-in protection in different system directions are implemented based on the shift information, so that screen burn-in can be prevented more effectively, and a service life of the screen can be prolonged.

In correspondence with the embodiment shown in FIG. 20, FIG. 21 is a diagram of pixel shift for screen burn-in protection of always-on display in different system directions according to an embodiment of this application. As shown in FIG. 21, when an always-on display direction of an electronic device is switched between a portrait mode and a landscape mode, a top margin, a shift range, and/or a shift distance are/is adaptively adjusted, so that the pixel shift for screen burn-in protection of the always-on display is adaptively performed on a display of the electronic device, and screen burn-in can be prevented more effectively.

Optionally, top margin coordinates are stored for always-on display (AOD), and a live wallpaper reads the top margin coordinates, to determine, by using the top margin coordinates, a location at which a screen-off picture is displayed.

FIG. 22 is a diagram of functional modules of a live wallpaper display control apparatus 2200 according to an embodiment of this application. As shown in FIG. 22, the apparatus 2200 includes:

- a determining module 2201, configured to: after a user triggers a lock screen function of an electronic device, determine whether the current electronic device supports live wallpaper display in different directions, where

- a first display module 2202, configured to display the live wallpaper on a lock screen page; and
- an obtaining module 2203, configured to obtain the current system direction.

Optionally, the current system direction is determined by the obtaining module 2203 by using a current device posture of the electronic device, and may be obtained by the obtaining module 2203 by using a posture sensor in the electronic device. The posture sensor may include a gyroscope sensor or a triaxial acceleration sensor, and may further include another sensor. This is not limited in this application.

Explanation of the current system direction is described in detail in embodiments shown in FIG. 13 and FIG. 15. For brevity, details are not described herein again.

The first display module 2202 is configured to display the live wallpaper on the lock screen page based on the current system direction.

A second display module 2204 is configured to perform the always-on display on the screen-off page based on the current system direction.

A third display module 2205 is configured to display a home screen wallpaper in the current system direction.

Two or more display modules of the first display module 2202, the second display module 2204, and the third display module 2205 may be integrated into one general display module, and the integrated general display module has all functions of the two or more display modules.

It should be understood that the determining module 2201 is an optional module.

Optionally, the apparatus 2200 may further include a receiving module, configured to: receive a notification of locking the screen of the electronic device, and receive a notification of unlocking the electronic device.

In embodiments of this application, for a problem that a live wallpaper theme can only be displayed in a portrait orientation and cannot be displayed in different system directions of the electronic device in the conventional technology, the live wallpaper display control apparatus that can display the live wallpaper theme in different directions of the electronic device based on the system direction is provided. When a screen-off operation is performed on the electronic device, a lock screen application displays the live wallpaper based on the current system direction, and the screen-off page can implement the always-on display in different system directions based on stored display locations and display resources, so that visual experience of the user can be improved. In addition, when the live wallpaper is a super wallpaper theme, home screen display, lock screen display, and the always-on display can end up achieving super wallpaper animation effects associatively in different system directions of the electronic device, which further improves use experience of the user.

According to the embodiment shown in FIG. 22, FIG. 23 is a diagram of functional modules of a live wallpaper display control apparatus 2300 according to an embodiment of this application. As shown in FIG. 23, based on the apparatus 2200, the following functional modules are added to the apparatus 2300.

A storage module 2301 is configured to: when an always-on display style is used, store display resources in a first direction and a second direction.

The first system direction and the second system direction are two of four system directions of an electronic device. The first system direction and the second system direction are perpendicular to each other and are at an included angle of 90°, and respectively represent a landscape orientation and a portrait orientation of the electronic device.

Similarly, the display resource in the second system direction includes a bitmap resource in the second system direction, and may further include another display resource. This is not limited in this application.

A processing module 2302 is configured to: when a user performs a screen-off operation on the electronic device, obtain display resources in a third system direction and a fourth system direction based on the display resources in the first system direction and the second system direction.

The third system direction and the first system direction are positive and negative directions of each other, and the fourth system direction and the second system direction are positive and negative directions of each other.

For example, the electronic device is a foldable phone. Based on a natural coordinate system of the phone, system directions of the foldable phone are: an x-axis positive direction, an x-axis negative direction, a y-axis positive direction, and a y-axis negative direction. The first system direction and the second system direction may be the x-axis positive direction and the y-axis positive direction respectively. Correspondingly, the third system direction and the fourth system direction are the x-axis negative direction and the y-axis negative direction respectively.

Similarly, the display resource in the fourth system direction includes a bitmap resource in the fourth system direction, and may further include another display resource. This is not limited in this application.

The processing module 2302 performs byte reversal on the display resources (for example, the bitmap resources) in the first system direction and the second system direction, to obtain the display resources in the third system direction and the fourth system direction, thereby implementing the always-on display in different system directions.

Optionally, the bitmap is stored in AGRB_4444 and RGB565 formats, two bytes represent one pixel, and the processing module 2302 implements bitmap reversal by reversing a byte sequence.

Optionally, in the always-on display, the processing module 2302 is further configured to calculate shift information in a current system direction relative to a screen based on a ratio of a screen height in the current system direction to a screen height in an original system direction.

For example, the system direction of the electronic device is switched from the landscape orientation to the portrait orientation, that is, the original system direction is the landscape orientation, and the current system direction is the portrait orientation. It is assumed that the screen height in the current system direction is 2, the screen height in the original system direction is 1, and the ratio of the screen height in the current system direction to the screen height in the original system direction is 2:1. A ratio of a top margin in the current system direction to a top margin in the original system direction is equal to 2:1, a ratio of a shift range in the current system direction to a shift range in the original system direction is equal to 2:1, and a ratio of a shift distance in the current system direction to a shift distance in the original system direction is equal to 2:1.

Optionally, the processing module 2302 is further configured to perform pixel shift for screen burn-in protection based on the shift information.

Explanation of the pixel shift for screen burn-in protection is described in detail in the embodiment shown in FIG. 20. For brevity, details are not described herein again.

In addition, for the always-on display in different system directions, a fixed initial location, shift range, and shift distance are no longer used. Instead, the proper shift information is adaptively calculated by using the height in the current screen direction, and the always-on display and pixel shift for screen burn-in protection in different system directions are implemented based on the shift information, so that screen burn-in can be prevented more effectively.
