With rapid development of electronic devices, an electronic device has more than one display. For example, a foldable mobile phone may include a large screen and a small screen. The large screen may be a display that is most frequently used by a user of the foldable mobile phone, has a complete display capability, and has a complete status bar, a navigation bar, a launcher icon, and the like. The user can complete most routine operations on the large screen. The small screen may be a smaller screen, has a weak display capability, and can display only some simple element content, for example, time, weather, and a battery level.

SUMMARY

Embodiments of this application provide a multi-screen unlocking method and apparatus, and an electronic device, to enrich screen lock display of a small screen, thereby implementing differentiated display on each screen and improving user experience.

To achieve the foregoing objectives, the following technical solutions are used in embodiments of this application.

According to a first aspect, an embodiment of this application provides a multi-screen unlocking method, applied to an electronic device. The electronic device includes a first display and a second display, the first display corresponds to a first application, and the second display corresponds to a second application. The method may include: In response to receiving a first operation performed by a user on the electronic device, the electronic device determines that a status of the electronic device is a screen-locked state. The first display displays a first screen lock interface by using the first application, and the second display displays a second screen lock interface by using the second application, where the first screen lock interface is different from the second screen lock interface. The second application sends a first message to the first application in response to receiving a second operation performed by the user on the second display. In response to the first message, the first application displays a first unlocked interface by using the first display, and indicates the electronic device to switch from the screen-locked state to an unlocked state. The first application sends a second message to the second application. In response to the second message, the second application displays a second unlocked interface by using the second display.

The first display may be a primary screen (or referred to as a large screen), and the second display may be a secondary screen (or referred to as a small screen). Certainly, the first display may be a secondary screen, and the second display may be a primary screen. This is not specifically limited in this embodiment of this application.

DESCRIPTION OF EMBODIMENTS

The following describes the technical solutions in embodiments of this application with reference to the accompanying drawings in embodiments of this application. In description in embodiments of this application, “/” means “or” unless otherwise specified. For example, A/B may represent A or B. In this specification, “and/or” describes only an association relationship for describing 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. In addition, in the descriptions in embodiments of this application, “a plurality of” means two or more.

The terms “first” and “second” mentioned below are merely intended for a purpose of description, and shall not be understood as an indication or implication of relative importance or implicit indication of the number of indicated technical features. Therefore, a feature limited by “first” or “second” may explicitly or implicitly include one or more features. In the descriptions of embodiments, unless otherwise specified, “a plurality of” means two or more.

Currently, an electronic device has more than one display. For example, the electronic device may be a foldable mobile phone. In FIG. 1A, the foldable mobile phone is in an unfolded state, 2 shown in FIG. 1A is a folding line, and the foldable mobile phone in FIG. 1B is in a folded state. The foldable mobile phone may include a primary screen 1 and a secondary screen 3. When both the primary screen and the secondary screen are in a screen-locked state, the primary screen 1 displays a screen lock interface 101 shown in FIG. 1A, and the secondary screen 3 displays a screen lock interface 102 shown in FIG. 1B. It can be learned that the screen lock interface 101 is the same as the screen lock interface 102. When a user unlocks the secondary screen, the user needs to perform an unlocking operation on the screen lock interface 101 of the primary screen. The primary screen of the foldable mobile phone receives the unlocking operation of the user. In response to the unlocking operation, the primary screen of the foldable mobile phone is unlocked, and the secondary screen of the foldable mobile phone is indicated to be unlocked. In this way, in a process in which the user unlocks the secondary screen of the foldable mobile phone, the user needs to operate the primary screen to perform unlocking, so as to unlock the secondary screen. Consequently, real-time unlocking performance of the secondary screen is low, and user experience is poor.

To resolve the foregoing technical problem, in this embodiment of this application, in response to receiving a first operation performed by the user on the electronic device, the electronic device determines that a status of the electronic device is a screen-locked state. In this case, a first display displays a first screen lock interface, and a second display displays a second screen lock interface, where the first screen lock interface is different from the second screen lock interface. A second application sends a first message to a first application in response to receiving a second operation performed by the user on the second display. In response to the first message, the first application displays a first unlocked interface by using the first display, and indicates the electronic device to switch from the screen-locked state to an unlocked state. The first application sends a second message to the second application. In response to the second message, the second application displays a second unlocked interface by using the second display. The first display is locked by using the first application, and the second display is locked by using the second application. The first application and the second application are two independent applications. In this way, the first display and the second display may display two different screen lock interfaces. In addition, the first display and the second display may further have different interaction behaviors. The user may independently operate the second display to perform unlocking, that is, the user may perform an unlocking operation on the second display, so that real-time unlocking performance is high, and user experience is improved. When the user operates one screen for unlocking, a screen lock interface of another screen is not affected.

That “the first application displays a first unlocked interface by using the first display, and indicates the electronic device to switch from the screen-locked state to an unlocked state” may be understood as that after the first application displays the first unlocked interface by using the first display, the first application indicates the electronic device to switch from the screen-locked state to the unlocked state; or in response to the first message, the first application displays the first unlocked interface by using the first display, and in response to the first message, the first application indicates the electronic device to switch from the screen-locked state to the unlocked state. In other words, in response to the first message, the first application may perform two things at the same time. One thing is to display the first unlocked interface by using the first display, and the other thing is to indicate the electronic device to switch from the screen-locked state to the unlocked state. This may not be specifically limited in this embodiment of this application.

To resolve the foregoing technical problem, in some other embodiments, in response to receiving a first operation performed by a user on the electronic device, the electronic device determines that a status of the electronic device is a screen-locked state. In this case, a first display displays a first screen lock interface, and a second display displays a second screen lock interface, where the first screen lock interface is different from the second screen lock interface. The second display displays a second unlocked interface in response to receiving a second operation performed by the user on the second display. A second application indicates the electronic device to switch from the screen-locked state to an unlocked state, and sends a first message to a first application. In response to the first message, the first application displays a first unlocked interface by using the first display. The first display is locked by using the first application, and the second display is locked by using the second application. The first application and the second application are two independent applications. In this way, the first display and the second display may display two different screen lock interfaces. In addition, the first display and the second display may further have different interaction behaviors. The user may independently operate the second display to perform unlocking, that is, the user may perform an unlocking operation on the second display, so that real-time unlocking performance is high, and user experience is improved. When the user operates one screen for unlocking, a screen lock interface of another screen is not affected.

The electronic device may be a device having a plurality of displays. A form of the electronic device is not specifically limited in this embodiment of this application. For example, the electronic device may be a foldable device, the electronic device may be a separable device, or the electronic device may be a device in a common form.

In some embodiments, the electronic device may include a foldable device. When the foldable device is in an unfolded state, the first display is unfolded on an expanded surface of the foldable device. When the foldable device is in a folded state, the second display is located on an outer surface of the foldable device. For example, the foldable device may be a foldable mobile phone. The first display is locked by using the first application, and the second display is locked by using the second application. The first application and the second application are two independent applications. In this way, the first display and the second display may display two different screen lock interfaces. FIG. 2A is a schematic diagram of a first screen lock interface of a first display 1 of a foldable mobile phone. FIG. 2B is a schematic diagram of a second screen lock interface of a second display 2 of the foldable mobile phone. As shown in FIG. 2A and FIG. 2B, a first screen lock interface 103 is different from a second screen lock interface 104. Certainly, the first screen lock interface and the second screen lock interface include but are not limited to the interfaces shown in FIG. 2A and FIG. 2B. This is not specifically limited in this embodiment of this application.

For example, the electronic device may be specifically a device like a mobile phone, a tablet computer, an in-vehicle device, a notebook computer, a smart screen, a wearable device (such as a smartwatch), an augmented reality (AR)/virtual reality (VR) device, an ultra-mobile personal computer (UMPC), a netbook, or a personal digital assistant (PDA). A device type of the electronic device is not limited in this embodiment of this application.

After being processed by the baseband processor, the low-frequency baseband signal is transmitted to the application processor. The application processor outputs a sound signal by using an audio device (which is not limited to the loudspeaker 370A, the receiver 370B, or the like), or displays an image or video by using the display 394. In some embodiments, the modem processor may be an independent device. In some other embodiments, the modem processor may be independent of the processor 310, and is disposed in a same device as the mobile communication module 350 or another function module.

There are a plurality of types of pressure sensors 380A such as 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 force is applied to the pressure sensor 380A, capacitance between electrodes changes. The device 100 determines strength of the pressure based on a change in the capacitance. When a touch operation is performed on the display 394, the device 100 detects strength of the touch operation based on the pressure sensor 380A. The device 100 may further calculate a touch position based on a detection signal of the pressure sensor 380A. In some embodiments, touch operations that are performed in a same touch position 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 executed.

The gyroscope sensor 380B may be configured to implement image stabilization during image shooting. For example, when the shutter is pressed, the gyroscope sensor 380B detects an angle at which the 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 device 100 through reverse motion, to implement image stabilization. The gyroscope sensor 380B may further be used in a navigation scenario and a motion-controlled gaming scenario.

The barometric pressure sensor 380C is configured to measure barometric pressure. In some embodiments, the device 100 calculates an altitude by using a barometric pressure value measured by the barometric pressure sensor 380C, to assist in positioning and navigation.

The light emitting diode may be an infrared light emitting diode. The device 100 transmits infrared light by using the light emitting diode. The device 100 detects infrared reflected light from a nearby object by using the photodiode. When plenty of reflected light is detected, it may be determined that there is an object near the device 100. When insufficient reflected light is detected, the device 100 may determine that there is no object near the device 100. The device 100 may detect, by using the optical proximity sensor 380G, whether the user holds the device 100 close to an ear to make a call, so as to automatically turn off the screen to save power.

The temperature sensor 380J is configured to detect a temperature. In some embodiments, the device 100 executes a temperature processing policy by using the temperature detected by the temperature sensor 380J. For example, when the temperature reported by the temperature sensor 380J exceeds a threshold, the device 100 lowers performance of a processor located near the temperature sensor 380J, to reduce power consumption to implement thermal protection. In some other embodiments, when the temperature is lower than another threshold, the device 100 heats the battery 342 to avoid abnormal shutdown of the device 100 caused by a low temperature. In some other embodiments, when the temperature is lower than still another threshold, the device 100 boosts an output voltage of the battery 342, to avoid abnormal shutdown caused by a low temperature.

The touch sensor 380K is also referred to as a “touch device”. The touch sensor 380K may be disposed on the display 394, and the touch sensor 380K and the display 394 form a touchscreen, which is also referred to as a “touchscreen”.

The touch sensor may transfer the detected touch operation to the application processor to determine a type of the touch event. The display 394 may provide a visual output related to the touch operation. In some other embodiments, the touch sensor 380K may alternatively be disposed on a surface of the device 100, or disposed in a position different from the display 394.

The bone conduction sensor 380M may obtain a vibration signal. In some embodiments, the bone conduction sensor 380M may obtain a vibration signal of a vibration bone of a human vocal-cord part. The bone conduction sensor 380M may further be in contact with a human pulse, to receive a blood pressure beating signal. In some embodiments, the bone conduction sensor 380M may alternatively be disposed in the headset, to obtain a bone conduction headset. The audio module 370 may obtain a voice signal through parsing based on the vibration signal that is of the vibration bone of the vocal-cord part and that is obtained by the bone conduction sensor 380M, to implement a voice function. The application processor may parse heart rate information based on the blood pressure beating signal obtained by the bone conduction sensor 380M, to implement a heart rate detection function.

The device 100 may receive input from the button, and generate button signal input related to user settings and function control of the device 100.

The motor 391 may generate a vibration prompt. The motor 391 may be configured to provide an incoming call vibration prompt and touch vibration feedback. For example, touch operations performed on different applications (for example, photographing and audio playing) may correspond to different vibration feedback effects. For touch operations performed on different areas of the display 394, the motor 391 may also correspond to different vibration feedback effects. Different application scenarios (for example, a time reminder, information receiving, an alarm clock, and a game) may also correspond to different vibration feedback effects. The touch vibration feedback effect may be further customized.

In this embodiment of this application, there may be a plurality of displays 394. For example, the display 394 may include a first display and a second display. When the first display and the second display are in a screen-locked state, the first display displays a first screen lock interface by using a first application, and the second display displays a second screen lock interface by using a second application. The first application and the second application may be system applications of the electronic device. The internal memory 331 may store code of the first application and code of the second application. In some embodiments, when the user operates the second display, the second application sends a first message to the first application, where the first message indicates the first application not to display the screen lock interface. The processor 310 runs the code of the first application, so that the first application displays the first unlocked interface by using the first display. In this case, the processor 310 determines that a status of the electronic device is switched from the screen-locked state to an unlocked state. In addition, the first application sends a second message to the second application, where the second message indicates the second application not to display the screen lock interface. The processor 310 runs the code of the second application, so that the second application displays a second unlocked interface by using the second display. In some other embodiments, when the user operates the second display, the second display displays a second unlocked interface. In this case, the second application indicates the processor 310 to determine to switch a status of the electronic device to an unlocked state. The second application sends a first message to the first application, where the first message indicates the first application not to display the screen lock interface. In this case, the processor 310 runs the code of the first application, so that the first application displays the first unlocked interface by using the first display.

The indicator 392 may be an indicator light, and may be configured to indicate a charging status and a power change, or may be configured to indicate a message, a missed call, a notification, or the like.

Certainly, the device 100 may further include another function unit. This is not limited in this embodiment of this application.

It should be noted that the device 100 may be a desktop computer, a portable computer, a network server, a mobile phone, a tablet computer, a wireless terminal, an embedded device, a chip system, or a device having a similar structure in FIG. 3. In addition, the composition structure shown in FIG. 3 does not constitute a limitation on the communication apparatus. In addition to the components shown in FIG. 3, the communication apparatus may include more or fewer components than the components shown in the figure, or some components may be combined, or different component arrangements may be used.

In this embodiment of this application, the chip system may include a chip, or may include a chip and another discrete component.

It may be understood that a structure shown in this embodiment of this application does not constitute a specific limitation on the electronic device 100. In some other embodiments of this application, the electronic device 100 may include more or fewer components than those shown in the figure, or some components may be combined, or some components may be split, or different component arrangements may be used. The components shown in the figure may be implemented by hardware, software, or a combination of software and hardware.

FIG. 4 is a block diagram of a software structure of an electronic device 100 according to an embodiment of the present invention.

In a layered architecture, software is divided into several layers, and each layer has a clear role and task. The layers communicate with each other through a software interface. In some embodiments, a software structure of the electronic device 100 may be divided into three layers: an application layer, an application framework layer, and a kernel layer from top to bottom.

The application layer may include a series of application packages.

As shown in FIG. 4, the application package may include applications such as first screen lock application (namely, a first application), second screen lock application (namely, a second application), Camera, Gallery, Calendar, Phone, Maps, Navigation, WLAN, Bluetooth, Music, Videos, and Messages.

The first screen lock application mainly provides interface display in a first display (or referred to as a primary screen) in a screen-locked state, an operation of unlocking the primary screen, change management of a system locked/unlocked state, and synchronous processing of locking/unlocking of a plurality of displays.

The second screen lock application is mainly responsible for content display in a second display (or referred to as a secondary screen) in a screen-locked state, an unlocking operation performed by a user on the screen, a prompt, and synchronization with a system state.

The application framework layer provides an application programming interface (API) and a programming framework for an application at the application layer. The application framework layer includes some predefined functions.

As shown in FIG. 4, the application framework layer may include a screen lock manager (Keyguard management service), an AMS, a power manager, a multi-screen manager, a fingerprint manager, a face authentication manager, a password manager, voiceprint authentication, and the like.

The screen lock manager is mainly responsible for synchronizing locked/unlocked states of a plurality of screens.

The kernel layer is a layer between hardware and software. The kernel layer includes at least a binder driver, a display driver for the first display, a display driver for the second display, a camera driver, an audio driver, a sensor driver, and the like.

The following describes an example of a working process of software and hardware of the electronic device 100 with reference to a screen lock scenario.

When the touch sensor 180K receives a touch operation, a corresponding hardware interrupt is sent to the kernel layer. The kernel layer processes the touch operation into an original input event (including information such as touch coordinates and a time stamp of the touch operation). The original input event is stored at the kernel layer. The application framework layer obtains the original input event from the kernel layer, and identifies a control corresponding to the input event. For example, the touch operation is a touch tap operation, and a control corresponding to the tap operation is a control of a first screen lock application icon. The first screen lock application invokes an interface of the application framework layer to start the first screen lock application, and then invokes the kernel layer to start the display driver for the first display. The first display reads a screen lock interface in a first screen container, and displays the screen lock interface.

An embodiment of this application provides a multi-screen unlocking method, and the method is applied to an electronic device. The electronic device may include a plurality of displays, and each display corresponds to one screen lock application. For example, the electronic device may include a first display and a second display. The first display corresponds to a first screen lock application (for example, the first application), and the second display corresponds to a second screen lock application (for example, the second application). In this embodiment of this application, an example in which the first display of the electronic device is a primary screen and the second display of the electronic device is a secondary screen is used for description. Further, as shown in FIG. 4, the electronic device may further include a screen lock manager. The second screen lock application registers a communication interface and a callback interface by using the screen lock manager. The communication interface is used for communication between the second screen lock application and the first screen lock application. The callback interface is used by the first screen lock application to invoke the second screen lock application.

FIG. 5A is a schematic diagram of a procedure of a multi-screen unlocking method according to an embodiment of this application. FIG. 5B is a schematic diagram of a procedure of a multi-screen unlocking method according to an embodiment of this application.

Refer to FIG. 5A and FIG. 5B. A specific procedure of the multi-screen unlocking method provided in this embodiment of this application may be described in different phases. Details are as follows.

Phase 1: Screen Lock Phase

S501: An electronic device receives a screen lock operation performed by a user on the electronic device.

The screen lock operation may include a screen-off operation, a gesture operation, and the like. The gesture operation may include a sliding operation, a pressing operation, a tapping operation, and the like. This may not be specifically limited in this embodiment of this application.

Certainly, the screen lock operation may further vary with different electronic devices. For example, the electronic device may be a foldable mobile phone, and correspondingly, the screen lock operation may include a folding operation. For example, the foldable mobile phone is folded. Alternatively, the electronic device may be a common mobile phone. Correspondingly, the screen lock operation may include inserting and removing an intelligent (SIM) card. Alternatively, the electronic device may be a tablet computer. Correspondingly, the screen lock operation may include tapping a Home button.

S502: In response to the screen lock operation, a first display of the electronic device displays a first screen lock interface, and a second display of the electronic device displays a second screen lock interface, where the second screen lock interface is different from the first screen lock interface.

In a specific implementation, in response to the first screen lock operation, a first screen lock application (for example, the first application) of the electronic device performs screen locking. In this case, the first display reads the first screen lock interface in a first screen container, and displays the first screen lock interface. The first screen lock application sends a broadcast message, where the broadcast message carries an identifier of the second screen lock application (for example, the second application) and screen lock indication information. The second screen lock application receives the broadcast message. In this case, the second display reads the second screen lock interface in a second screen container, and displays the second screen lock interface, where the second screen lock interface is different from the first screen lock interface.

Display content of the first display is different from display content of the second display. This may be specifically implemented as follows.

In a first manner, the electronic device may identify related specification information of the first display, for example, resolution and dots per inch (DPI). The electronic device may establish the first screen container for the first display based on the related specification information of the first display. The first screen container may store the first screen lock interface of the first screen lock application. Similarly, the electronic device may further identify related specification information of the second display. The electronic device may establish the second screen container for the second display based on the related specification information of the second display. The second screen container may store the second screen lock interface of the second screen lock application, and the second screen lock interface is different from the first screen lock interface. The first screen container and the second screen container may be distinguished by using different display identifiers (Display IDs).

In this way, the first display of the electronic device can read the first screen lock interface in the first screen container, and display the first screen lock interface. Similarly, the second display of the electronic device can read the second screen lock interface in the second screen container, and display the second screen lock interface. In this case, the first screen lock interface displayed by the first display is different from the second screen lock interface displayed by the second display.

In a second manner, compared with the first manner, the electronic device may convert information such as an application icon, an application interface, an SMS message received by the electronic device, a status bar, and a specified screen lock interface in the electronic device into the second screen lock interface that matches specification information of the second display, and store the second screen lock interface in the second screen container. Subsequently, the first display can read the first screen lock interface in the first screen container, and display the first screen lock interface. The second display can read the second screen lock interface in the second screen container, and the second screen lock interface is different from the first screen lock interface. In this way, two different screen lock interfaces can run independently in a same operating system.

In a specific implementation, it is assumed that the electronic device is a foldable mobile phone. When the user uses the foldable mobile phone to play music and the foldable mobile phone is in an unfolded state, the user triggers a screen lock operation, for example, the user taps a screen-off button. In this case, the foldable mobile phone performs a screen lock operation, and the foldable mobile phone may display a screen lock interface 103 shown in FIG. 2A. When the user uses the foldable mobile phone to play music, and the foldable mobile phone is in a folded state, that is, when a secondary screen (the second display) of the foldable mobile phone displays an interface shown in FIG. 6A, the user triggers a screen lock operation. In this case, the foldable mobile phone performs the screen lock operation, and the foldable mobile phone may display a screen lock interface 104 shown in FIG. 6B. Certainly, the foldable mobile phone may display a screen lock interface 104 shown in FIG. 6C. It can be seen that a screen lock interface (namely, the first screen lock interface) of a primary screen is different from the screen lock interface (namely, the second screen lock interface) of the secondary screen.

Certainly, the second screen lock interface may alternatively be displayed as a pull-down notification bar, a notification, a widget of a third application, or an application icon of the third application. For example, the second display may display a screen lock interface 107 shown in FIG. 7A. Information such as a position and a weather condition may be displayed in the screen lock interface 107. For example, the position is Jiangxia District, a current temperature is 15° C., a highest temperature today is 15° C., a lowest temperature today is 7° C., and weather is sunny. The second display may further display a screen lock interface 108 shown in FIG. 7B, and navigation information may be displayed in the screen lock interface 108, for example, an icon, a roadmap, and prompt information of a positioning application, where the prompt information may be “Enter Shenjiang Road after 23 meters”. The second display may further display a screen lock interface 109 shown in FIG. 7C, and a notification may be displayed in the screen lock interface 109, for example, an SMS message, where the SMS message may be “Amber, there is a sunrise at the Shanghai East Art Center this weekend, and Director Jinxing . . . ”. The second display may further display a screen lock interface 110 shown in FIG. 7D, and the application icon of the third application may be displayed in the screen lock interface 110, for example, the application icon and prompt information of the third application, where the prompt information is “Protected by a screen lock”, and the like. Certainly, the second display may further display other content. This is not listed one by one in this embodiment of this application.

In some embodiments, the multi-screen unlocking method provided in this embodiment of this application may further include: when a screen status of the second display is a screen-locked state, switching an interface of the second display from the second screen lock interface to an interface 1 (for example, the second interface) in response to receiving an operation 1 (for example, the third operation) of the user on the second display. The operation 1 may include a gesture operation, and the gesture operation may include a sliding operation. For example, the sliding operation may be an operation of sliding from one end of the first display towards the other end. The sliding operation may alternatively be a sliding operation with a specified track. This is not specifically limited in this embodiment of this application. The interface 1 may be a screen lock interface different from the second screen lock interface. For example, the second screen lock interface is the screen lock interface shown in FIG. 6B or FIG. 6C, and the interface 1 is the screen lock interface shown in FIG. 7A to FIG. 7D.

It should be noted herein that, in response to the screen lock operation, the electronic device may further determine that a status of the electronic device is a screen-locked state. This step is not mandatory. Therefore, this step may be briefly mentioned in this embodiment of this application.

Phase 2: Unlocking phase.

Unlocking the electronic device may be implemented in the following manners.

In a first manner, the user operates the second display, and the second application performs unlocking. Details are shown in FIG. 5A.

S503: The electronic device receives an unlocking operation (for example, the second operation) performed by the user on the second display.

The unlocking operation may include a password unlocking operation, a face authentication unlocking operation, a fingerprint unlocking operation, and the like. Certainly, the unlocking operation may further include another unlocking operation, for example, a voiceprint unlocking operation. This is not specifically limited in this embodiment of this application.

S504: The second display displays a second unlocked interface in response to receiving the unlocking operation (for example, the second operation) performed by the user on the second display.

Specifically, the second application exits the second screen lock interface in response to the unlocking operation of the user. That is, the second display implements display of the second unlocked interface by using the second application.

S505: The second application indicates the electronic device to switch from the screen-locked state to an unlocked state, and sends a first message to the first application. Correspondingly, the first application receives the first message.

The first message indicates the first application not to display the screen lock interface. The first message may carry operation information of the user.

S506: In response to the first message, the first application displays a first unlocked interface by using the first display.

For example, the first display may be a primary screen (or referred to as a large screen), and the second display may be a secondary screen (or referred to as a small screen); or the first display may be a secondary screen, and the second display may be a primary screen. S503 to S506 are described in detail below, and may be specifically as follows.

Manner 1: Password Unlocking

S11: The second display displays an interface 2 in response to receiving an operation 2 performed by the user on the second display, where the interface 2 includes a password input area.

The operation 2 may include a gesture operation, and the gesture operation may include a sliding operation. For example, the sliding operation may be an operation of sliding from one end of the second display towards the other end. The sliding operation may alternatively be a sliding operation with a specified track. This is not specifically limited in this embodiment of this application.

The password input area may include a numeric keyboard or a gesture area.

For example, the second display is the primary screen, and the user performs a sliding operation on a screen lock interface shown in FIG. 8A. A display interface of the electronic device jumps from an interface 103 shown in FIG. 8A to an interface 111 shown in FIG. 8B. A password input area is displayed in the interface 111. After the user enters a password, the interface of the electronic device may jump to an interface 112 shown in FIG. 8C. Certainly, if the electronic device plays a song before the screen is locked, after the user enters the password, the interface of the electronic device may jump to a playing interface of the song.

S12: In response to receiving the password entered by the user in the password input area, the second screen lock application corresponding to the second display sends the password to a password manager of the electronic device.

S13: The password manager receives the password, and performs verification on the password. After the verification on the password succeeds, the password manager generates verification success information, and sends the verification success information to the second screen lock application.

S14: The second display displays the second unlocked interface by using the second screen lock application, and the second screen lock application sends a message 1 to the first screen lock application corresponding to the first display, where the message 1 indicates the first screen lock application to perform screen unlocking.

The message 1 may be a broadcast message. For example, the broadcast message may be represented as android.intent.action.USER_PRESENT.

That the second display displays the second unlocked interface by using the second screen lock application may be specifically implemented as follows: The second screen container can store the second screen lock interface of the second screen lock application. Therefore, the second screen lock application does not drive the second display to read the second screen lock interface in the second screen container; or the second screen lock application drives the second display to stop reading the second screen lock interface in the second screen container. Certainly, there may be another implementation. This is not specifically limited in this embodiment of this application.

S15: In response to the message 1, the first screen lock application displays the first unlocked interface by using the first display.

Manner 2: Face Authentication Unlocking

S31: In response to receiving an operation 4 performed by the user on the second display, the second screen lock application sends a message 2 to a face authentication manager, where the message 2 carries face authentication indication information.

The operation 4 may be the same as the operation 1. For details, refer to the foregoing related descriptions. Details are not described in this embodiment of this application.

S32: The face authentication manager triggers, based on the message 2, the electronic device to capture a face image.

Specifically, the electronic device starts a camera (for example, a camera), and captures the face image of the user by using the camera.

S33: The face authentication manager performs authentication the face image captured by the electronic device.

Specifically, the face authentication manager compares the face image captured by the electronic device with a pre-stored face image of an authorized user.

S34: After the authentication on the face image succeeds, the face authentication manager generates authentication success information, and sends the authentication success information to the second screen lock application. In addition, the electronic device determines that the screen status is switched from the screen-locked state to the unlocked state.

S35: The second screen lock application sends a broadcast message to the first screen lock application, where the broadcast message carries the authentication success information and screen status update prompt information.

For example, the broadcast message may be represented as com.huawei.keyguard.action.KEYGUARD_AUTH_STATE. A parameter carried in the broadcast message includes an authentication result and a biometric authentication manner, for example, a fingerprint, a face, a bone voiceprint, and a smart device.

S36: The second screen lock application displays the second unlocked interface by using the second display.

After the second screen lock application successfully performs unlocking, the second screen lock application may send an unlocking broadcast. For example, the unlocking broadcast may be represented as android.intent.action.USER_PRESENT.

S37: In response to the broadcast message, the first screen lock application displays the first unlocked interface by using the first display.

In a second manner, the user operates the second display, and the first application performs unlocking. Details are shown in FIG. 5B.

S503′: The electronic device receives an unlocking operation (for example, the second operation) performed by the user on the second display.

S503′ is the same as S503. For details, refer to the foregoing description. Details are not described herein again.

S504′: The second application sends a first message to the first application in response to receiving the unlocking operation (for example, the second operation) performed by the user on the second display. Correspondingly, the first application receives the first message.

In this embodiment of this application, related content of descriptions of S23 and S24 is the same as that of S13 to S15, and details are not described herein again.

In a case, a size of the second display is small, and it is inconvenient for the user to enter the password on the second display. To resolve the foregoing problem, the multi-screen unlocking method provided in this embodiment of this application may further include: The second display displays first prompt information in response to receiving the second operation performed by the user on the second display, where the first prompt information is used to prompt the user to perform unlocking in a preset unlocking manner. For example, the electronic device is a foldable mobile phone. The second operation may be an operation performed by the user on the second display, for example, an operation of double-tapping the second screen lock interface of the second display. When the user double-taps the second screen lock interface, an interface of the foldable mobile phone is displayed as an interface 113 shown in FIG. 8D. In the interface 113, because the size of the second display is small and it is inconvenient to display a password input area, prompt information is displayed in the interface. For example, the prompt information may be “Please unfold the mobile phone for unlocking”. Certainly, the prompt information may alternatively be “Use your fingerprint or swipe up to unlock”. This is not specifically limited herein in this embodiment of this application.

Manner 2: Face Authentication Unlocking

S41: The second application sends a message 3 (for example, the first message) to the first application in response to receiving an operation 5 (for example, the second operation) performed by the user on the second display, where the message 3 carries face authentication indication information.

For example, the message 3 may be a broadcast message, and the broadcast message may be represented as com.huawei.keyguard.action.KEYGUARD_ASSISTAN_SCREEN. A parameter carried in the broadcast message includes an indication for triggering facial recognition.
