The communication module 190 may include one or more communication processors that are operable independently from the processor 120 (e.g., the application processor (AP)) and supports a direct (e.g., wired) communication or a wireless communication. According to an embodiment, the communication module 190 may include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 194 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules may communicate with the external electronic device via the first network 198 (e.g., a short-range communication network, such as Bluetooth™, wireless-fidelity (Wi-Fi) direct, or infrared data association (IrDA)) or the second network 199 (e.g., a long-range communication network, such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., LAN or wide area network (WAN)). These various types of communication modules may be implemented as a single component (e.g., a single chip), or may be implemented as multi components (e.g., multi chips) separate from each other. The wireless communication module 192 may identify and authenticate the electronic device 101 in a communication network, such as the first network 198 or the second network 199, using subscriber information (e.g., international mobile subscriber identity (IMSI)) stored in the subscriber identification module 196.
The wireless communication module 192 may support a 5G network, after a 4G network, and next-generation communication technology, e.g., new radio (NR) access technology.

The antenna module 197 may transmit or receive a signal or power to or from the outside (e.g., the external electronic device) of the electronic device 101. According to an embodiment, the antenna module 197 may include an antenna including a radiating element including a conductive material or a conductive pattern formed in or on a substrate (e.g., a printed circuit board (PCB)). According to an embodiment, the antenna module 197 may include a plurality of antennas (e.g., array antennas). In such a case, at least one antenna appropriate for a communication scheme used in the communication network, such as the first network 198 or the second network 199, may be selected, for example, by the communication module 190 (e.g., the wireless communication module 192) from the plurality of antennas. The signal or the power may then be transmitted or received between the communication module 190 and the external electronic device via the selected at least one antenna. According to an embodiment, another component (e.g., a radio frequency integrated circuit (RFIC)) other than the radiating element may be additionally formed as part of the antenna module 197.
According to various embodiments, the antenna module 197 may form a mmWave antenna module. According to an embodiment, the mmWave antenna module may include a printed circuit board, a RFIC disposed on a first surface (e.g., the bottom surface) of the printed circuit board, or adjacent to the first surface and capable of supporting a designated high-frequency band (e.g., the mmWave band), and a plurality of antennas (e.g., array antennas) disposed on a second surface (e.g., the top or a side surface) of the printed circuit board, or adjacent to the second surface and capable of transmitting or receiving signals of the designated high-frequency band.
At least some of the above-described components may be coupled mutually and communicate signals (e.g., commands or data) therebetween via an inter-peripheral communication scheme (e.g., a bus, general purpose input and output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)).
According to an embodiment, commands or data may be transmitted or received between the electronic device 101 and the external electronic device 104 via the server 108 coupled with the second network 199. Each of the electronic devices 102 or 104 may be a device of a same type as, or a different type, from the electronic device 101. According to an embodiment, all or some of operations to be executed at the electronic device 101 may be executed at one or more of the external electronic devices 102, 104, or 108. For example, if the electronic device 101 should perform a function or a service automatically, or in response to a request from a user or another device, the electronic device 101, instead of, or in addition to, executing the function or the service, may request the one or more external electronic devices to perform at least part of the function or the service. The one or more external electronic devices receiving the request may perform the at least part of the function or the service requested, or an additional function or an additional service related to the request, and transfer an outcome of the performing to the electronic device 101. The electronic device 101 may provide the outcome, with or without further processing of the outcome, as at least part of a reply to the request.

Hereinafter, in the present disclosure, a low power state may refer, for example, to a state in which a processor (hereinafter, a processor 310 of
The electronic device may display an image through the display panel using a display driving circuit based on image information obtained from the processor. In a method of displaying the image, the image may be displayed through the display panel based on a command mode or a video mode. For example, even in case that the image is displayed through a screen for the low power state, modes as described above may be used. A method of displaying the image through the screen for the low power state based on the command mode may, for example, be as follows. For example, the processor before switching to the sleep state (e.g., active state) may transmit the image information to the display driving circuit. The display driving circuit may store the image information in memory (e.g., graphic random access memory (GRAM)) in the display driving circuit. After the processor is switched to the sleep state, the display driving circuit may display the image through the display panel by scanning the image information in the memory. In this case, the processor may be in the sleep state. A method of displaying the image through the screen for the low power state based on the video mode may, for example, be as follows. Unlike the command mode, the video mode may represent a mode for displaying the image without using the memory. For example, the video mode may represent a mode provided by the display driving circuit that does not include the memory. For example, the display driving circuit may display the image information obtained from the processor through the display panel. In this case, the processor may be in the low power state operating at the minimum refresh rate.
The low power state may be referred to as the AOD mode. The OPR may represent the ratio of at least some pixels to be used to display the visual object among a plurality of pixels (or subpixels) included in a display panel (e.g., a display panel 340 of
Referring to
In the example 201, the electronic device 101 may display the screen 210 including the visual object 220 displaying the time and the visual object 231 displaying the weather in the low power state. For convenience of explanation, the example 201 illustrates the screen 210 displaying the visual object 231 whose transparency is adjusted based on a second software application, but the present disclosure is not limited thereto. For example, the screen 210 may include only the visual object 220 representing the time. For example, the second software application may include a software application for setting the screen 210 for the low power state.
In the example 201, the electronic device 101 may be in a state of displaying the screen 210 including the visual object 220 and the visual object 231 in the low power state. In this case, the electronic device 101 may identify an event for the visual object 231 in the screen 210. For example, the event may include at least one of a display (or addition) of the visual object, activation of an AOD function, a designated interval (e.g., 1 minute), a change (or update) of at least a portion of the visual object, or an event that changes a theme of the screen. The screen on which the theme is changed may include screens that the electronic device 101 may display. In the example 201, the event is in a state in which the visual object 231 is already displayed, and may represent an event for the changing of at least a portion of the visual object. In case of identifying the event, a processor (e.g., a processor 310 of
In the example 201, the electronic device 101 may identify the visual object 232 of the example 202 to be displayed through the screen 210 based on the event. As in the example 202, the electronic device 101 may identify that the screen 210 including the visual object 232 and the visual object 220 changed from the visual object 231 will be displayed, based on the event. The visual object 232 may be identified based on the image obtained from the first software application. However, the visual object 232 included in the screen 210 of the example 202 may represent a visual object in which the OPR has a higher OPR than a reference OPR. For example, the reference OPR may be identified based on power used to display the screen 210 in the low power state. For example, the reference OPR may be set to at least one value between 10% and 15%. However, the present disclosure is not limited thereto.
Referring to the example 202, in case that the visual object 232 having the OPR higher than the reference OPR is displayed, burn-in may occur on the display panel of the electronic device 101. In addition, in case that the visual object 232 having the OPR higher than the reference OPR is displayed, power consumption of the electronic device 101 may increase. In addition, in case that the state in which the visual object 232 having the OPR higher than the reference OPR is displayed changes to a state in which a screen different from the screen 210 (e.g., a lock screen or home screen) is displayed, an afterimage may be formed on the display panel of the electronic device 101.
In order to address the above-described problem, the electronic device 101 may identify the OPR of the visual object 232 before displaying the visual object 232. For example, the electronic device 101 may identify the OPR of the visual object 232 (or the image) using the second software application based on an image representing the visual object 232 obtained from the first software application. In addition, the electronic device 101 may identify an alpha value representing a transparency of the visual object 232 based on the image. For example, the electronic device 101 may identify the alpha value of the visual object 232 as a first value.
For example, the electronic device 101 may identify whether the OPR of the visual object 232 exceeds the reference OPR using the second software application. For example, the electronic device 101 may change the first value to a second value lower than the first value in response to the OPR exceeding the reference OPR. The electronic device 101 may display a visual object having the changed second value through the screen 210 based on changing the value representing the transparency of the visual object 232 to the second value. Referring to the example 203, the electronic device 101 may display the screen 210 including the visual object 233 and the visual object 220 having the second value lower than the visual object 232. In this case, a transparency of the visual object 220 may be maintained. An OPR of the visual object 233 having the second value may be lower than the OPR of the visual object 232 having the first value. In other words, the OPR may be adjusted based on the alpha value. An example of adjusting the OPR based on the changed alpha value is described in greater detail below with reference to
For example, the visual object 233 may have a lower brightness level shown from outside than the visual object 232. For example, the OPR may be lowered by adjusting the transparency of the visual object. Since the visual object 233 whose brightness level is lowered according to the changed OPR is displayed, burn-in and the afterimage may not occur on the display panel of the electronic device 101. In addition, since an OPR value for display in the electronic device 101 decreases, the power consumption of the electronic device 101 may be reduced.
In
Referring to the above, in case of displaying a visual object (e.g., the widget) for a specific software application through the AOD screen, as a state of the visual object is changed, it may be necessary to dynamically adjust an OPR for pixels to be used to display the visual object. For example, that the state of the visual object is changed may include at least one of the case that the visual object is not displayed and then displayed in response to the event, the case that the visual object is displayed and then displayed a visual object in which at least a portion of the visual object has changed in response to the event, or the case that the theme for the screen is changed in response to the event. The screen on which the theme is changed may include the screens that the electronic device 101 may display.
As described in example 202, in case that the OPR of the visual object 232 to be displayed exceeds the reference OPR, the burn-in and the afterimage may occur in the display panel as the screen 210 for the low power state is displayed. In addition, in case that the OPR exceeds the reference OPR, a problem in which the power consumption of the electronic device 101 increases in the low power state may occur.
For example, the burn-in may occur as a life of a light emitting element of each of a plurality of subpixels included in the display panel decreases. For example, each of the plurality of subpixels may include a light emitting element for displaying red (R), green (G), or blue (B). Compared to the light-emitting element for displaying R or the light-emitting element for displaying G, a life of the light-emitting element for displaying B is short. Accordingly, in case that the screen 210 including the visual object 232 is displayed for a long time, the burn-in may occur.
For example, depending on a hysteresis characteristic of the display panel, an instantaneous afterimage may occur. The instantaneous afterimage is a phenomenon in which a screen displayed in the past affects a currently changed screen in case that a state of the display panel is instantaneously changed.
For example, a ratio of at least some pixels to be used to display a specific visual object among entire pixels included in the display panel may be defined as the OPR. The OPR may represent a ratio of a sum of RGB values displayed by the at least some pixels for a case that each of the entire pixels displays white. For example, the white may represent a case in which each of a gradation (or grayscale) of R, a gradation (or grayscale) of G, and a gradation (or grayscale) of B are maximized and/or increased. For example, the gradation (or grayscale) may be formed at a level of 256 having a range of 0 to 255. In case that the gradation (or grayscale) value is 0, it may represent the darkest color, and in case that the gradation (or grayscale) is 255, it may represent the brightest color. The white color may represent a state in which it is R (255), G (255), or B (255). Red may represent a state in which it is R (255), G (0), and B (0). For example, assuming a case that only one pixel exists, an OPR for displaying the red may be 33.3%. In other words, in case that many pixels among the entire pixels are turned on or in case that the gradation (or grayscale) value of each RGB increases, the OPR may increase. In case that the OPR increases, the power consumption may increase. However, since the low power state is a state which is driven through limited power consumption, the OPR for displaying the visual object needs to be adjusted below the reference OPR. In general, the OPR may sample the number of pixels to be used to display the visual object in order to be adjusted below the reference OPR. For example, the sampling may represent scaling the number of pixels to be used to display the visual object. For example, in case that the number of pixels to be used to display the visual object is 100 and is sampled at 75%, the number of pixels to be used to display the visual object may be adjusted to 75. For example, in case that an OPR of the image representing the visual object exceeds the reference OPR, the OPR of the image may be sampled at 75%. In case that the sampled OPR exceeds the reference OPR, the OPR of the visual object may be adjusted to a value less than or equal to the reference OPR by reducing a size of the image or reducing a value of the gradation (or grayscale) for displaying the image.

For example, an interface may be used for transmission of the image from the processor 310 to the display driving circuit 320. For example, the interface may be a display serial interface (DSI) of a mobile industry process interface (MIPI) alliance. However, the present disclosure is not limited thereto. For example, that the processor 310 may be operatively (or operably) coupled with the display driving circuit 320 may represent that the display driving circuit 320 operates based on instructions executed by the processor 310. For example, that the processor 310 may be operatively (or operably) coupled with the display driving circuit 320 may represent that the display driving circuit 320 is controlled by the processor 310. For example, the processor 310 may display the image on the display panel 340 using the display driving circuit 320 based on a video mode of the DSI. For example, the processor 310 and the display driving circuit 320 may be configured with at least one processor.
For example, the display driving circuit 320 may process the image based on a characteristic of the image and/or a characteristic of the display panel 340. For example, the display driving circuit 320 may provide signals for displaying the image to the display panel 340. For example, the display driving circuit 320 may be operatively (or operably) coupled with the display panel 340. For example, that the display driving circuit 320 is operatively (or operably) coupled with the display panel 340 may refer to the display driving circuit 320 being connected to the display panel 340. For example, that the display driving circuit 320 is operatively (or operably) coupled with the display panel 340 may refer to the display panel 340 being controlled by the display driving circuit 320. However, it is not limited thereto.
For example, the display driving circuit 320 may include components for displaying the visual object (e.g., a widget) through the display panel 340 on the screen for the low power state. For example, the display driving circuit 320 may include an OPR identification module 321, a gamma voltage identification module 323, an image modulation module 325, and a signal generation module 327. Each of these modules may include various circuitry and/or executable program instructions.
For example, the OPR identification module 321 may identify the OPR of the visual object obtained from the processor 310. For example, the OPR identification module 321 may identify the OPR of the visual object included in the image by obtaining data on the OPR of the visual object from the processor 310 or using the image obtained from the processor 310. In addition, the OPR identified by the OPR identification module 321 may be provided to the gamma voltage identification module 323 and the image modulation module 325.
For example, the gamma voltage identification module 323 may obtain a plurality of gamma voltages based on at least some of the set gamma curves. The gamma may be a parameter for representing a correlation between a brightness level (or gray level) of a signal input to the display panel 340 and luminance on a screen displayed through the display panel 340. Depending on the gamma value, a tone of brightness displayed even on the same screen may change. For example, in case that the gamma value is 1, the brightness of the input signal and the brightness output on the screen may be the same. In case that the gamma value is greater than 1, the brightness output on the screen may be brighter than the brightness of the input signal. In case that the gamma value is less than 1, the brightness output on the screen may be darker than the brightness of the input signal. The gamma curve may refer to a line representing luminance according to gradation (or grayscale) that changes depending on the gamma value. For example, the gamma voltage identification module 323 may change the gamma curve by changing the maximum gamma voltage and/or the minimum gamma voltage. For example, based on the OPR obtained from the OPR identification module 321, the gamma voltage identification module 323 may provide information on the plurality of gamma voltages to the signal generation module 327.
For example, the image modulation module 325 may modulate or modify the image obtained from the processor 310 based on the OPR obtained from the OPR identification module 321. For example, the image modulation module 325 may provide information on the modulated (or modified) image to the signal generation module 327.
For example, the signal generation module 327 may generate signals based at least in part on information obtained from the gamma voltage identification module 323 and the image modulation module 325. For example, the signals may be obtained by converting the information obtained from the gamma voltage identification module 323 and/or the information obtained from the image modulation module 325. For example, the signal generation module 327 may include a decoder for converting the information. The signal generation module 327 may transmit the obtained signals to the display panel 340.
For example, the display panel 340 may display a screen based on the signals obtained from the signal generation module 327. For example, the screen may include at least one of the image, the visual object, and a user interface. For example, the display panel 340 may include a plurality of pixels (or subpixels). For example, the display panel 340 may display the screen including the visual object based on at least some of the plurality of pixels.
For example, the memory 330 may include image information obtained from a specific software application (e.g., a first software application) and/or the second software application. For example, the memory 330 may include one or more instructions that cause an operation of the at least one processor (e.g., the processor 310, the display driving circuit 320), when executed by the at least one processor. For example, in the memory 330, the one or more instructions (or commands) representing calculation and/or operation to be performed by the at least one processor of the electronic device 101 on data may be stored. A set of one or more instructions may be referred to as a program, firmware, operating system, process, routine, sub-routine and/or application. Hereinafter, that the software application was installed in the electronic device 101 may refer, for example, to the one or more instructions being provided in a form of a software application are stored in the memory 330 and the one or more applications being stored in an executable format (e.g., a file having an extension designated by the operating system of the electronic device 101) by the at least one processor of the electronic device 101. According to an embodiment, the electronic device 101 may perform an operation according to an embodiment of the present disclosure by executing the one or more instructions stored in the memory 330.
In case that the processor 310 is in a sleep state, the low power state may represent a state in which the screen including the visual object is displayed on the display panel 340. However, the present disclosure is not limited thereto. For example, the low power state may represent a state in which the display panel 340 operates at a minimum refresh rate (e.g., 1 Hz) while the screen including the visual object is displayed on the display panel 340. Hereinafter, for convenience of explanation, the low power state of the present disclosure assumes that the processor is in the sleep state.
The low power state may be referred to as the AOD mode. For example, the function of displaying the screen in the low power state may be referred to as AOD (or AOD function). The architecture may represent a simplified architecture of an electronic device 101 for supporting the AOD. However, the present disclosure is not limited thereto. For example, the electronic device 101 may further include or may less include other components in addition to a component included in the architecture of
Referring to
For example, programs classified as the framework 410 may provide an executable application programming interface (API) based on another program. For example, a program classified as the application 400 may cause execution of a function supported by the programs classified as the framework 410, by calling the API.
For example, the application 400 may represent a layer that performs interaction with a user. The application 400 may include An AOD software application 401, a first software application 403 for providing weather information, and a second software application 405 for setting of a screen for the AOD. However, the present disclosure is not limited thereto. For example, the application 400 may further include other software applications. In addition, the first software application 403 is an example and may be a software application for providing another service. For example, the software application for providing the other service may include a software application for a calendar, a note, or a clock. For example, the first software application 403 may refer to a 3rd party application. For example, the 3rd party application may refer to a software application provided by the 3rd party rather than a manufacturer (e.g., a 1st party) of the electronic device 101 or a telecommunication company (e.g., a 2nd party) that provides a communication service of the electronic device 101. The 3rd party application may represent a software application installed in the electronic device 101 based on an installation program downloaded through a store that provides the software application. In addition, for convenience of explanation, the second software application 405 is referred to as a software application for setting of the screen (or a screen for the low power state) for the AOD, but is not limited thereto. For example, the second software application 405 may represent a software application for setting of a lock screen as well as a screen for the AOD. For example, the second software application 405 may be related to a software application for changing setting of a user interface (UI) or user experience (UX), including the setting of the AOD screen or the lock screen. For example, the second software application 405 may change setting for displaying the visual object through the AOD screen or the lock screen based on information obtained from the first software application 403. Hereinafter, an operation performed based on the second software application 405 and the first software application 403 is illustrated, but the present disclosure is not limited thereto. For example, an operation performed using the first software application 403 and/or the second software application 405 may be performed by the processor 340.
For example, a plurality of programs may be classified into the framework 410. For example, the framework 410 may include a window manager 411, a power manager 413, an AOD manager 415, and a context framework 417. For example, the window manager 411 may trigger the AOD when the screen is turned on/off in relation to the AOD software application 401. For example, the power manager 413 may control an active matrix organic light emitting diode (AMOLED) low power mode (ALPM) and a hybrid low power mode (HLPM) in relation to the AOD software application 401. For example, the AOD manager 415 may obtain notification information and may set a command for display in relation to the AOD software application 401. For example, the second software application 405 may change the setting of the AOD screen based on execution of the AOD manager 415. In other words, the second software application 405 may change the setting of the AOD screen using a program of the framework 410. The context framework 417 may obtain an AOD on/off state in relation to the AOD software application 401.
For example, the kernel 420 may manage resources of the electronic device 101. The kernel 420 may include drivers for executing a function supported by the programs classified as the framework 410. The kernel 420 may not support the interaction with the user.
The device and method according to the present disclosure may display a visual object included in a screen displayed while executing the AOD function (e.g., the low power state) through the second software application 405. The visual object may be identified based on an image obtained by the second software application 405 from the first software application 403. For example, the image may represent the visual object. The device and method according to the present disclosure may display a screen including the visual object processed using the second software application 405 based on the image while executing the AOD function.
The operations of
Referring to
In operation 505, the electronic device 101 may identify an event for displaying the visual object in the AOD screen while the AOD screen is displayed. For example, the electronic device 101 may identify the event. For example, the event may include at least one of a display (or addition) of the visual object, activation of an AOD function, a designated interval, a change (or update) of at least a portion of the visual object, or an event that changes a theme of the screen. An event for displaying (or adding) the visual object, and an event for changing (or updating) at least a portion of the visual object may be identified using the first software application. The screen on which the theme is changed may include screens that the electronic device 101 may display. In the example of
In operation 510, the electronic device 101 may identify the OPR of the visual object using a second software application in response to the event. For example, in response to identifying the event, the electronic device 101 may identify an image obtained from the first software application using the second software application. For example, the electronic device 101 may identify whether the image will be displayed through the AOD screen. An example related to this is described in greater detail below with reference to
For example, the electronic device 101 may identify an alpha value representing a transparency of the image using the second software application based on the image. For example, the alpha value of the image may be identified as a first value.
In operation 515, the electronic device 101 may identify whether the identified OPR exceeds a reference OPR. For example, the electronic device 101 may identify whether the OPR exceeds the reference OPR using the second software application. For example, the reference OPR may be identified based on power used to display the AOD screen in the low power state. The OPR of operation 515 may represent an OPR identified based on pixels to be used to display the visual object among a plurality of pixels included in the display panel 340, or an OPR sampled from the identified OPR. An example will be described in greater detail below with reference to
In operation 520, the electronic device 101 may display the AOD screen including the visual object based on changing the first value representing an attribute of the visual object to a second value lower than the first value using the second software application. For example, the attribute may represent a transparency of the visual object. For example, the electronic device 101 may change the first value identified using the second software application to the second value. The electronic device 101 may display the AOD screen including the visual object having the changed second value through the display panel 340. Accordingly, the visual object having the second value may have a lower brightness level compared to the visual object having the first value. In other words, the visual object having the second value may be displayed darker than the visual object having the first value. For convenience of explanation, in
In operation 525, the electronic device 101 may display the AOD screen including the visual object based on changing the first value representing the attribute of the visual object to a third value that is lower than the first value and higher than the second value using the second software application. For example, the attribute may represent the transparency. For example, the electronic device 101 may change the identified first value to the third value using the second software application. The third value may represent a value that is lower than the first value and higher than the second value. The electronic device 101 may display the AOD screen including the visual object having the changed third value through the display panel 340. Accordingly, the visual object having the third value may have a lower brightness level compared to the visual object having the first value. In addition, the visual object having the third value may have a higher brightness level compared to the visual object having the second value. In other words, the visual object having the third value may be darker than the visual object represented by the image provided by the first software application (e.g., the visual object having the first value), and brighter than the visual object having the second value changed based on the second software application. This may be to display the visual object through the AOD screen.
In operation 520 and operation 525, the portion (e.g., the processor 310) of the at least one processor included in the electronic device 101 may switch from the wake-up state to the sleep state after providing information for displaying the visual object (e.g., the visual object having the second value or the third value) whose transparency has been changed to another portion (e.g., the display driving circuit 320). However, the present disclosure is not limited thereto. For example, in case that a display panel (e.g., the display panel 340) operates at a minimum refresh rate based on the portion (e.g., the processor 310) of the at least one processor, the portion may not switch to the sleep state.
Although not illustrated in
In addition, the electronic device 101 may perform an operation to display the visual object brighter even in case that the OPR of the visual object having an attribute changed through operation 520 or operation 525 is lower than the reference value from the reference OPR. For example, the electronic device 101 may identify the OPR of the visual object having changed attribute through operation 520 or operation 525 in response to the event. The electronic device 101 may identify whether the identified OPR is lower than the reference value from the reference OPR. The electronic device 101 may change the attribute of the visual object in response to the identified OPR having a value lower than the reference value. Accordingly, the identified OPR may be changed to a higher value. In other words, the changed OPR may have a higher value than the identified OPR, and the visual object according to this may be displayed brighter.

In operation 550, the electronic device 101 may identify an event for displaying the visual object. For example, while the AOD screen is displayed, the electronic device 101 may identify the event for displaying the visual object in the AOD screen. For example, the event may include at least one of a display (or addition) of the visual object, activation of an AOD function, a designated interval, a change (or update) of at least a portion of the visual object, or an event that changes a theme of the screen. An event for displaying (or adding) the visual object, and an event for changing (or updating) at least a portion of the visual object may be identified using the first software application. The screen on which the theme is changed may include screens that the electronic device 101 may display. While the electronic device 101 identifies the event using the first software application, a portion (e.g., the processor 310 of
In operation 555, the electronic device 101 may identify whether a screen on which the visual object is to be displayed is the screen for the low power state. For example, the electronic device 101 may identify whether an image representing the visual object obtained from the first software application is an image to be displayed on the AOD screen using the second software application. In operation 555, the electronic device 101 may perform operation 560 in response to identifying that the screen on which the visual object is to be displayed is the AOD screen. On the other hand, the electronic device 101 may perform operation 565 in response to identifying that the screen on which the visual object is to be displayed is another screen. For example, the other screen may represent a screen for a state different from the low power state. For example, the other screen may include a screen (or a lock screen) for displaying a lock state of the electronic device 101.
In operation 560, the electronic device 101 may identify an OPR of the visual object using the second software application. Operation 560 may be understood substantially the same as operation 510 of
In operation 565, the electronic device 101 may display another screen including the visual object. The other screen may represent the lock screen different from the AOD screen. For example, the other screen may include the visual object. For example, since the visual object is displayed in the state different from the low power state, the visual object may have an OPR based on a deactivated second software application. In other words, the OPR may represent an OPR identified through the image provided by the first software application.
The components illustrated in
Referring to
The electronic device 101 may include a plug-in 605 to apply data processed by the second software application 610 to the lock screen 601 and the AOD screen 602. For example, the plug-in 605 may represent a configuration for controlling the data obtained from the second software application 610 to be shared with the system 600. For example, the plug-in 605 may not share the data with the system 600 in case that the data provided by the second software application 610 is difficult to display through the AOD screen 602, based on a limitation (e.g., memory) of the system 600. In other words, the plug-in 605 may control the data exceeding a reference size not to be displayed on a screen (e.g., the lock screen 601 or the AOD screen 602) of the system 600.
The low power state may be referred to as an AOD mode. The software application for displaying the visual object in the low power state may represent a second software application. For example, the second software application may set a screen for the low power state. The screen for the low power state may be referred to as an AOD screen. The setting may include adding, deleting, or editing a visual object (e.g., a widget) related to another software application to be displayed on the screen.

For example, the electronic device 101 may display the third UI 635 that is at least partially superimposed on the second UI 630, in response to at least one user input for an area of the second UI 630. For example, in case that there is no item displayed on the second UI 630, the area may represent an area corresponding to a visual object representing widget addition displayed on the second UI 630. For example, the item may represent visual information displayed on the second software application corresponding to the visual object (e.g., the widget) to be displayed on the AOD screen. The item displayed on the second UI 630 may include an item representing a widget that has already been added. The visual object representing the widget addition may include text (e.g., “Can contain a widget.”).

OPR for the visual object using the second software application. For example, in case that the visual object is newly added, the electronic device 101 may identify the OPR for the visual object. However, the present disclosure is not limited thereto. For example, in relation to a previously added visual object, in case that an event is identified using a software application related to the previously added visual object, an OPR for the previously added visual object may be identified.
For example, in case that the identified OPR exceeds a reference OPR, the electronic device 101 may identify a changed OPR based on a transparency from the identified OPR.
In operation 670, the electronic device 101 may update information on the visual object having the changed OPR to the AOD 620. In operation 680, based on the information on the visual object, the electronic device 101 may display a screen (the AOD screen, or the screen for the low power state) including the visual object having the changed OPR, through a display panel 340.

Referring to the example 710, the second UI 712 may include a plurality of areas representing the positions of visual objects (e.g., widgets) that may be displayed in the AOD screen. For example, the plurality of areas may be disposed at different positions. For example, the plurality of areas may be formed in different sizes. However, the present disclosure is not limited thereto, and the plurality of areas may have the same size. Referring to the example 710, an area 714 of the plurality of areas may include an item representing time. The item representing the time may represent a widget that is being displayed on the AOD screen. For example, the item may represent visual information corresponding to a visual object that is displayed or to be displayed through the AOD screen.
Referring to the examples 710 and 720, in case that an area 716 of the second UI 712 does not include an item, a third UI 722 for adding at least one item to be added to the area 716 may be displayed in response to at least one user input for the area 716. For example, the third UI 722 may be displayed in a state that is at least partially superimposed on the second UI 712. For example, the third UI 722 may be displayed by sliding in a direction from a bottom to a top of the display panel 340 of the electronic device 101. However, the present disclosure is not limited thereto. In addition, in case that the plurality of areas of the second UI 712 do not include the item, the third UI 722 for adding the at least one item to be added may be displayed after the second UI 712 is displayed.
Referring to the example 720, the third UI 722 may include a plurality of items. For example, the plurality of items may include an item 723 related to a software application to provide weather information, an item 724 related to a software application to provide stock information, an item 725 related to a software application to provide an analog watch, and an item 726 related to a software application to provide an alarm function. However, the present disclosure is not limited thereto. For example, the plurality of items included in the third UI 722 may be related to widgets of a software application (e.g., a first software application) that may be displayed through a home screen of the electronic device 101. For example, the plurality of items may represent a preview of widgets of a software application that may be added to the home screen. As described above, the electronic device 101 may display the widget of the software application that may be displayed through the home screen through the AOD screen by adding the at least one item through the third UI 722.
Referring to the examples 710 and 720, in case that an area 718 of the second UI 712 includes at least one item, in response to at least one user input for the icon 719 located at a point of a boundary representing the area 718, the third UI 722 for adding at least one item to be added to the area 718 may be displayed.
Referring to the example 720, based on a user input for at least one item among the plurality of items included in the third UI 722, the at least one item may be added to the second UI 712. Referring to the example 740, based on a user input for one item 725 among the plurality of items included in the third UI 722, the second UI 712 may include the item 725 in the area 716. Referring to the example 750, based on a user input for two items 725 and 726 among the plurality of items included in the third UI 722, the second UI 712 may include items 725 and 726 in the area 716.
For convenience of description, the examples 760 and 770 assume an operation of disposing the item 725 for the example 750 in which two items 725 and 726 are added.
Referring to the example 760, the items 725 and 726 may be disposed at an arbitrary position in the area 716. For example, based on a user input for the item 725, a position of the item 725 may be changed in the area 716. The user input may include a drag input. For example, a size of the item 725 may be variable. The size of the item 725 may be formed to have a size greater than or equal to a minimum size. For example, the minimum size may be set from a software application for providing the analog watch that provides the item 725.
Referring to the example 770, the item 725 may be moved to a position 775-1 of the item 726 according to the drag input. In this case, according to a movement of the item 725, the item 725 may be moved from the position 775-1 to a position 775-2. In other words, according to the movement of the item 725, a position of the existing item 726 may be rearranged.
Referring to the above, the electronic device 101 may add a visual object displayed on the AOD screen and may change a position of the visual object using the second software application. For example, the electronic device 101 may change the addition, deletion, or disposition of the visual object by adding, deleting, or disposing an item corresponding to the visual object on the user interface using a user interface of the second software application.

Referring to the above, the electronic device 101 may display the AOD screen including at least one visual object based on a freely deployable layout. In this case, the line widget or the box widget may not have problems of burn-in/afterimage or power consumption even if it is displayed through the AOD screen. However, the home widget is a widget based on the software application provided by the third party, and problems of burn-in/afterimage or power consumption may occur. Accordingly, according to an embodiment of the present disclosure, in case that the identified OPR of the home widget exceeds the reference OPR, the home widget may adjust and display the identified OPR to be less than the reference OPR based on a transparency. In case that the home widget is added to the AOD screen through the second software application, the electronic device 101 may display information notifying that visibility may be reduced as the OPR is adjusted through a user interface of the second software application. For example, the electronic device 101 may display a preview in which the home widget having the adjusted OPR is displayed on the AOD screen through the user interface of the second software application. In case that the home widget has a size that is limited to display through the AOD screen, the electronic device 101 may not display the home widget.

The second UI 900 may include added items 911 and 912 in response to a user input for a third UI (not illustrated). For example, the item 911 may represent a widget that displays an analog clock. For example, the item 912 may represent a widget that provides a calendar.
Referring to the example 902, the electronic device 101 may identify a user input for one of the items 911 and 912 of the second UI 900. For example, the user input may include a touch input for the item 911. In response to the touch input, the electronic device 101 may display the second UI 900 including an indicator 920 displaying that the item 911 has been selected.
Referring to the example 903, the electronic device 101 may display a fourth UI 930 for changing an attribute for the item 911.

Referring to the example 1001, the electronic device 101 may display a second UI 1000 of the second software application, which is a user interface for editing the AOD screen or a lock screen. The second UI 1000 may include an added item 1011 in response to a user input for a third UI (not illustrated). For example, the item 1011 may represent a widget that displays an analog clock. For example, the electronic device 101 may identify a user input for the item 1011 of the second UI 1000. For example, the user input may include a touch input for the item 1011. In response to the touch input, the electronic device 101 may display the second UI 1000 including an indicator 1010 representing that the item 1011 has been selected. The indicator 1010 may represent a current size of the item 1011.
Referring to the example 1002, the electronic device 101 may identify a user input for an icon 1025 located at a point of the indicator 1010 of the item 1011. For example, the user input may include a drag input. The electronic device 101 may change the size of the item 1011 based on the drag input for the icon 1025. For example, the electronic device 101 may enlarge the size of the item 1011 based on the drag input facing a direction expanding with respect to the icon 1025. Accordingly, referring to the example 1003, the indicator 1010 may be changed to an indicator 1020 for displaying the size of the enlarged item 1011.
Referring to the example 1004, as described in
For example, in response to a user input for the portion, the transparency of the item 1011 may be adjusted. The item 1011 of the example 1004 may be displayed more transparently than the item 1011 of the example 1003 in response to the user input for the portion.
Referring to the example 1004, the electronic device 101 may store an attribute for the adjusted item using the second software application.

Referring to the above, the electronic device 101 may change and store a size (or size and attribute) for the item using the second software application. Accordingly, the electronic device 101 may display the screen (e.g., the AOD screen) for the low power state including a visual object corresponding to the changed item.
The low power state may be referred to as the AOD mode. The screen may represent a screen for the low power state. For example, the screen may be referred to as an AOD screen.
An example 1100 of
In the example 1100 of
Examples 1200 and 1250 of
Referring to the example 1200, the electronic device 101 may display the screen 210 including a visual object 1210 representing weather information and a visual object 220 representing time. The visual object 1210 representing the weather information may be related to the first software application that provides the weather information. For example, the electronic device 101 may identify that the weather information has changed using the first software application. The electronic device 101 may identify the event that changes the visual object 1210 using the first software application in response to the weather information being changed. For example, the electronic device 101 may display the screen 210 including a visual object 1220 that has changed from the visual object 1210 and the visual object 220 representing the time, based on the event.
Referring to the example 1250, the electronic device 101 may display the screen 210 including a visual object 1260 representing the weather information and the visual object 220 representing the time. The visual object 1260 representing the weather information may be related to the first software application that provides the weather information. When comparing the examples 1200 and 1250, the visual object 1260 representing the weather information may be different from the visual object 1210, even though the same first software application providing the weather information is used. For example, the electronic device 101 may identify that the theme for the screens that the electronic device 101 may display is changed. For example, the theme may be changed based on at least one user input for the electronic device 101. The electronic device 101 may identify the event in response to the theme being changed. For example, the electronic device 101 may display the screen 210 including a visual object 1270 that has changed from the visual object 1260 and the visual object 220 representing the time, based on the event. For example, the visual object 1270 may represent a visual object to which a dark theme has been applied for the visual object 1260. For example, the dark theme may represent a theme in which a background of the visual object is inverted (e.g., from white to black).
For example, the electronic device 101 may identify an OPR of the visual object in response to identifying the event. For example, the electronic device 101 may identify the OPR of each of all visual objects included in the screen 210 in response to some event. For example, some event may include the electronic device 101 adding a new visual object through the second software application. In addition, some event may include electronic device 101 changing the AOD function from an off state to an on state. In addition, some event may include changing a theme of screens that the electronic device 101 may display. In addition, some event may include a designated interval (e.g., 1 minute). For example, the electronic device 101 may identify the OPR at the same timing according to the designated interval for all visual objects displayed on the screen 210. Identifying the OPR of each of all the visual objects at the same timing may reduce power consumption of the electronic device 101 compared to identifying the OPR of each of all the visual objects at different timings. This is because the electronic device 101 needs to frequently identify the OPR of each of all the visual objects at different timings. By identifying the OPR at the same timing for all visual objects for each designated interval, the power consumption of the electronic device 101 operating in the low power state may be reduced.
For example, in response to identifying the some event, the electronic device 101 may identify the OPR for each of the visual objects included in the screen 210 and may compare the identified OPR with a reference OPR. Accordingly, the electronic device 101 may adjust the OPR using the second software application for a visual object having an OPR exceeding the reference OPR. Afterwards, the electronic device 101 may display the visual object having the adjusted OPR through the screen 210.
The electronic device 101 may identify an OPR of a specific visual object in the screen 210 in response to other some event. For example, the other some event may include executing an update (or refresh) function for the specific visual object. The update function may be executed in response to a user input for an icon included in an area related to the specific visual object. The related area may include an adjacent area of the specific visual object or an area superimposed on the specific visual object. In addition, some other event may include identifying a display of the visual object and a change (or update) of at least a portion of the visual object using the first software application. For example, the electronic device 101 may identify the OPR of the specific visual object and may compare the identified OPR with the reference OPR in response to identifying the other some event. Accordingly, the electronic device 101 may adjust the OPR using the second software application in case of the specific visual object having an OPR exceeding the reference OPR. The electronic device 101 may display the specific visual object having the adjusted OPR through the screen 210.
The operations of
Although not illustrated in
In operation 1300, the electronic device 101 may identify the OPR of the visual object. For example, while the AOD screen is displayed, the electronic device 101 may identify an event for displaying the visual object in the AOD screen using the second software application. For example, the event may include at least one of a display (or addition) of the visual object, activation of an AOD function, a designated interval, a change (or update) of at least a portion of the visual object, or an event that changes a theme of the screen. An event for displaying (or adding) the visual object, and an event for changing (or updating) at least a portion of the visual object may be identified using the first software application. The screen on which the theme is changed may include screens that the electronic device 101 may display. For example, the electronic device 101 may identify a value representing a transparency of the visual object. For example, the electronic device 101 may identify an alpha value of the visual object as a first value.
For example, the electronic device 101 may identify an OPR for each of all visual objects included in the AOD screen in response to some event. For example, in response to other some event, the electronic device 101 may identify an OPR for a visual object related to the other some event. For example, the OPR of the visual object may represent a ratio of at least some pixels to be used to display the visual object among a plurality of pixels (or subpixels) included in a display panel (e.g., the display panel 340 of
For example, the electronic device 101 may identify the OPR of the visual object based on an image representing the visual object obtained from the first software application. In addition, the electronic device 101 may identify an OPR of each of a plurality of visual objects, based on an image obtained from a software application related to each of the plurality of visual objects, in case of identifying an OPR for the plurality of visual objects in the AOD screen.
Hereinafter, for convenience of explanation, it is assumed that the electronic device 101 has identified an OPR of one visual object in response to the event. For example, the electronic device 101 may identify the OPR of the visual object in response to the event. However, the present disclosure is not limited thereto, and the following operations may be individually performed for each of the plurality of visual objects.
In operation 1305, the electronic device 101 may identify whether the identified OPR exceeds a reference OPR. For example, the electronic device 101 may identify whether the identified OPR of the visual object exceeds the reference OPR using the second software application. For example, the reference OPR may be identified based on power used to display the AOD screen in the low power state. For example, the reference OPR may be set to at least one value between 10% and 15%. However, the present disclosure is not limited thereto.
In operation 1305, the electronic device 101 may perform operation 1310 in case that the identified OPR exceeds the reference OPR. On the other hand, the electronic device 101 may perform operation 1315 in case that the identified OPR is less than or equal to the reference OPR.
In operation 1310, the electronic device 101 may change the first value to a second value. For example, in response to the identified OPR greater than the reference OPR, the electronic device 101 may identify the second value that is changed from the first value representing the transparency of the visual object.
In operation 1315, the electronic device 101 may change the first value to a third value. For example, in response to the identified OPR less than or equal to the reference OPR, the electronic device 101 may identify the third value that is changed from the first value representing the transparency of the visual object. For example, the third value may be a value greater than the second value.
In operation 1320, the electronic device 101 may identify a new OPR based on the changed alpha value.
For example, the electronic device 101 may identify a new OPR of the visual object based on the second value. For example, the new OPR may represent a value scaled based on the second value for the OPR identified in operation 1300. For example, the new OPR may represent a value multiplied by a ratio between the first value and the second value with respect to the identified OPR. For example, assuming the identified OPR is 15%, the first value is 1.0, and the second value is 0.45, the new OPR may be 6.75%.
For example, the electronic device 101 may identify the new OPR of the visual object based on the third value. For example, the new OPR may represent a value scaled based on the third value for the OPR identified in operation 1300. For example, the new OPR may represent a value multiplied by a ratio between the first value and the third value with respect to the identified OPR. For example, assuming the identified OPR is 10%, the first value is 1.0, and the second value is 0.6, the new OPR may be 6%.
For example, in case that sampling is performed for the identified OPR as described above, the electronic device 101 may identify the new OPR based on the alpha value for the sampled OPR. For example, in case that the identified OPR is 28%, the sampled OPR may be 21%. For the sampled OPR, the new OPR adjusted using the changed alpha value (e.g., the second value is 0.45) may be 9.45%.
Although not illustrated in
Referring to the above, in case that the OPR identified for the visual object exceeds the reference OPR, the electronic device 101 may further adjust the transparency of the visual object. In addition, even in case that the OPR identified for the visual object is less than or equal to the reference OPR, the electronic device 101 may adjust the transparency of the visual object. Adjusting the transparency even in case that the identified OPR is less than or equal to the reference OPR is because a screen on which the visual object is displayed is the AOD screen for the low power state. Accordingly, the electronic device 101 may prevent and/or reduce burn-in and an afterimage and may reduce power consumption by dynamically adjusting the OPR in case of displaying the visual object (e.g., a widget) on the AOD screen.
The graph 1400 of
The graph 1400 illustrates a line 1410 representing an OPR that is changed based on a transparency after performing sampling (e.g., 75%) for the OPR of the visual object. For example, in case that the OPR of the visual object is 10%, the OPR may be changed to 7.5% according to sampling. For example, a reference line 1420 may represent a case in which an initially identified OPR for the visual object is 10%. Accordingly, a portion 1411 located on a left side of the line 1410 with respect to the reference line 1420 may represent a case in which an OPR identified for the visual object is less than or equal to 10%. A portion 1412 located on a right side of the line 1410 with respect to the reference line 1420 may represent a case in which the OPR identified for the visual object exceeds 10%.
Referring to the line 1410, the portion 1411 may represent a new OPR of the visual object identified based on changing a transparency of the visual object from a first value (e.g., 1.0) to a third value (e.g., 0.6). For example, in case that the initially identified OPR is 8%, the identified OPR may change to 6% depending on sampling. The new OPR identified based on the change of the transparency may be 3.6(6*0.6) %. In addition, referring to the line 1410, the portion 1412 may represent a new OPR of the visual object identified based on changing the transparency of the visual object from the first value (e.g., 1.0) to the second value (e.g., 0.45). For example, in case that the initially identified OPR is 16%, the identified OPR may be changed to 12% depending on sampling. The new OPR identified based on the change of the transparency may be 4.05(12*0.45) %. In addition, for example, in case that the initially identified OPR is 32%, the identified OPR may be changed to 24% depending on sampling. The new OPR identified based on the change of the transparency may be 10.80(24*0.45) %.
Referring to the above, the electronic device 101 may identify the OPR of the visual object and may identify a new OPR based on the transparency for the identified OPR. The graph 1400 illustrates an example of performing sampling by 75% for the OPR of the visual object and then identifying the new OPR based on the transparency, but the present disclosure is not limited thereto. For example, the new OPR may be identified based on an OPR for which sampling has not been performed. In addition, for example, the new OPR may be identified based on the OPR for which sampling has been performed at different rates.
The screen may represent a screen for the low power state. For example, the screen may be referred to as an AOD screen.
Referring to the example 1500, the electronic device 101 may display the AOD screen 210 including a visual object 1510 representing the weather information and a visual object 1520 representing time. For example, the visual object 1510 may be related to the first software application that provides the weather information. For example, in response to an event for displaying the visual object 1510, the electronic device 101 may display the AOD screen 210 based on an image representing the visual object 1510 obtained from the first software application. The visual object 1510 may represent a visual object that has not been processed by the second software application. For example, the visual object 1510 may represent a visual object having an OPR identified based on the image provided by the first software application.
Referring to the example 1550, the electronic device 101 may display the AOD screen 210 including a visual object 1560 representing the weather information and the visual object 1520 representing the time. For example, the visual object 1560 may be related to the first software application that provides the weather information. For example, the electronic device 101 may identify an image representing the visual object 1560 obtained from the first software application in response to an event for displaying the visual object 1560. For example, the electronic device 101 may adjust an OPR of the visual object 1560 using the second software application based on the image. For example, based on the image representing the visual object 1560 obtained from the first software application, the electronic device 101 may identify the OPR of the visual object 1560 using the second software application. The electronic device 101 may compare the identified OPR and a reference OPR using the second software application. In case that the identified OPR exceeds the reference OPR, the electronic device 101 may identify a new OPR by adjusting a transparency of the visual object 1560 using the second software application. Accordingly, the electronic device 101 may display the AOD screen 210 including the visual object 1560 having the new OPR.
Referring to the examples 1500 and 1550, the visual object 1510 may be brighter than visual object 1560. For example, a brightness level of the visual object 1510 may be higher than a brightness level of the visual object 1560. The brightness level may represent that the higher the level, the brighter it is.
Referring to the above, a brightness level of a visual object (e.g., a widget) displayed on the AOD screen 210 may be changed by adjusting a transparency using the second software application. Accordingly, the electronic device 101 may prevent and/or reduce burn-in and an afterimage and may reduce power consumption by dynamically adjusting the OPR in case of displaying the visual object (e.g., the widget) on the AOD screen 210.
For example, the screen may represent a screen for the low power state. For example, the screen may be referred to as an AOD screen. For example, the event may include at least one of a display (or addition) of the visual object, activation of an AOD function, a designated interval, a change (or update) of at least a portion of the visual object, or an event that changes a theme of the screen. The screen on which the theme is changed may include screens that the electronic device 101 may display.
Referring to the example 1600, the electronic device 101 may display the AOD screen 210 including the visual object 1610 representing the stock information and a visual object 1620 representing time. For example, the electronic device 101 may identify an image representing the visual object 1610 obtained from the first software application in response to an event for displaying the visual object 1610. For example, the electronic device 101 may adjust an OPR of the visual object 1610 using the second software application based on identifying that a theme of the electronic device 101 is the dark theme and the image. For example, based on the image representing the visual object 1610 obtained from the first software application, the electronic device 101 may identify the OPR of the visual object 1610 using the second software application. For example, the OPR of the visual object 1610 may be identified based on the visual object 1610 in a state in which black and white are inverted as the visual object to be displayed from the image applies the dark theme. For example, an OPR of an image to which the dark theme is applied may be lower than an OPR of an image to which the dark theme is not applied. The electronic device 101 may compare the identified OPR and a reference OPR using the second software application. In case that the identified OPR exceeds the reference OPR, the electronic device 101 may identify a new OPR by adjusting a transparency of the visual object 1610 using the second software application. Accordingly, the electronic device 101 may display the AOD screen 210 including the visual object 1610 having the new OPR.
Referring to the example 1650, the electronic device 101 may display the AOD screen 210 including the visual object 1660 representing the stock information and the visual object 1620 representing the time. For example, while displaying the visual object 1610, the electronic device 101 may identify an image representing the visual object 1660 obtained from the first software application in response to an event representing that the dark theme is released. For example, the electronic device 101 may adjust an OPR of the visual object 1660 using the second software application based on the image. For example, based on the image representing the visual object 1660 obtained from the first software application, the electronic device 101 may identify the OPR of the visual object 1660 using the second software application. For example, the OPR of the visual object 1660 may be identified based on the visual object 1660 to be displayed in case that the dark theme is released (or a state in which the dark theme is not applied). The electronic device 101 may compare the identified OPR and the reference OPR using the second software application. In case that the identified OPR exceeds the reference OPR, the electronic device 101 may identify a new OPR by adjusting a transparency of the visual object 1660 using the second software application. Accordingly, the electronic device 101 may display the AOD screen 210 including the visual object 1660 having the new OPR.
Referring to the examples 1600 and 1650, the visual object 1610 and the visual object 1660 may be displayed darker than a visual object (e.g., a visual object represented by the image) whose OPR is not adjusted based on deactivation of the second software application. For example, a brightness level of the visual object 1610 may be lower than a brightness level of the visual object whose OPR is not adjusted. For example, a brightness level of the visual object 1660 may be lower than the brightness level of the visual object whose OPR is not adjusted. The brightness level may represent that the higher the level, the brighter it is.

Referring to the example 1700, the electronic device 101 may display the AOD screen 210 including the visual object 1710 representing the weather information and a visual object 1720 representing time. For example, the electronic device 101 may identify an image representing the visual object 1710 obtained from the first software application in response to an event for displaying the visual object 1710. For example, the electronic device 101 may adjust the OPR of the visual object 1710 using the second software application based on the image. For example, based on the image representing the visual object 1710 obtained from the first software application, the electronic device 101 may identify the OPR of the visual object 1710 using the second software application. The electronic device 101 may compare the identified OPR and a reference OPR using the second software application. In case that the identified OPR exceeds the reference OPR, the electronic device 101 may identify a new OPR by adjusting a transparency of the visual object 1710 using the second software application. Accordingly, the electronic device 101 may display the AOD screen 210 including the visual object 1710 having the new OPR.
Referring to the example 1750, the electronic device 101 may display the AOD screen 210 including the visual object 1760 representing the weather information and the visual object 1720 representing the time. For example, while displaying the visual object 1710, the electronic device 101 may identify an image representing the visual object 1760 obtained from the first software application in response to an event that changes to the dark theme. For example, the electronic device 101 may adjust an OPR of the visual object 1760 using the second software application based on identifying that a theme of the electronic device 101 is the dark theme and the image. For example, based on the image representing the visual object 1760 obtained from the first software application, the electronic device 101 may identify the OPR of the visual object 1760 using the second software application. For example, the OPR of the visual object 1760 may be identified based on the visual object 1760 in a state in which black and white are inverted as the visual object to be displayed from the image applies the dark theme. For example, an OPR of an image to which the dark theme is applied may be lower than an OPR of an image to which the dark theme is not applied. The electronic device 101 may compare the identified OPR and a reference OPR using the second software application. In case that the identified OPR exceeds the reference OPR, the electronic device 101 may identify a new OPR by adjusting a transparency of the visual object 1760 using the second software application.

Referring to the example 1780, the electronic device 101 may display the AOD screen 210 including the visual object 1790 representing the weather information and the visual object 1720 representing the time. For example, while displaying the visual object 1710, the electronic device 101 may identify an image representing the visual object 1790 obtained from the first software application in response to the event that changes to the dark theme. For example, the electronic device 101 may display the visual object 1790 without additional OPR adjustment based on identifying that the theme of the electronic device 101 is the dark theme and the image. For example, the electronic device 101 may identify the OPR of the visual object 1790 based on the image and the dark theme. For example, the OPR of the visual object 1790 may be identified based on the visual object 1790 in the state in which black and white are inverted as the visual object to be displayed from the image applies the dark theme. As the dark theme is applied, in case that the OPR is less than or equal to the reference OPR, the electronic device 101 may display the AOD screen 210 including the visual object 1790 corresponding to the OPR without adjusting a transparency. As the dark theme is applied, in case that the OPR is less than or equal to the reference OPR, the electronic device 101 may identify a new OPR by slightly adjusting (e.g., in case of changing from the first value to the third value of
Referring to the examples 1700 and 1750, the visual object 1710 and the visual object 1760 may be displayed darker than the visual object (e.g., a visual object represented by the image) whose OPR is not adjusted based on the deactivation of the second software application. For example, a brightness level of the visual object 1710 may be lower than a brightness level of the visual object whose OPR is not adjusted. For example, a brightness level of the visual object 1760 may be lower than the brightness level of the visual object whose OPR is not adjusted. The brightness level may represent that the higher the level, the brighter it is.
Referring to examples 1750 and 1780, the visual object 1760 may be displayed darker than the visual object 1790. For example, even if the electronic device 101 is in a state in which the same dark theme is applied, a brightness level of the visual object 1760 may be lower than a brightness level of the visual object 1790 whose OPR is not adjusted (or slightly adjusted). For example, a brightness level of the visual object 1760 may be lower than the brightness level of the visual object 1790 whose OPR is not adjusted.

For example, the wearable device may identify the OPR of the visual object using the second software application, based on an image obtained from a software application (e.g., a first software application) that provides the visual object. For example, the wearable device may adjust a value representing a transparency of the visual object using the second software application in response to the identified OPR greater than the reference OPR. For example, the wearable device may identify a new OPR of the visual object based on the identified OPR and a value representing the adjusted transparency. For example, the wearable device may display the AOD screen including a visual object having the new OPR.
Referring to the examples 2000 and 2050, the AOD screens of the example 2050 may be displayed darker than the AOD screens of the example 2000. For example, at least one visual object in the AOD screen 2055 may be displayed darker than at least one visual object in the AOD screen 2005. For example, at least one visual object in the AOD screen 2060 may be displayed darker than at least one visual object in the AOD screen 2010.
