The method includes checking whether the display is in a low-power display mode for displaying an always-on display (AOD) screen, checking content of a first screen displayed on the display based on the display displaying the AOD screen, detecting a folding angle of the display, generating a second screen by reconstructing the first screen based on the folding angle, and displaying the second screen on the display.

Description

Technical Field

[0001] The present disclosure relates to a method for reducing display degradation of an electronic device and a technology for a foldable electronic device to which the method is applied. Background Art

[0002] The electronic device can display an image through a display provided on a surface of a housing. A plurality of pixels for displaying an image can be provided in the display. Each of the plurality of pixels can receive a data voltage and an emission signal for displaying an image from a display driver IC (DDI).

[0003] Meanwhile, electronic devices may have an always-on display (AOD) function, which means that when the display screen is turned off, information such as time, date, battery level, and notifications is always displayed on the display at low power. The AOD function allows users to view information such as time, date, battery level, and notifications without turning on the display screen.

[0004] Recently, a foldable electronic device has emerged whose display can be folded. The foldable electronic device can display different screens (images) on the display in a flat state and a folded state. In the folded state, the foldable electronic device can switch to a low-power display mode. The foldable electronic device can display an AOD screen in the low-power display mode. Summary of the Invention

[0005] Technical issues

[0006] When an electronic device continuously displays the same AOD screen on a display in low-power display mode, burn-in may occur. When burn-in occurs, a residual image may remain on the display. To prevent burn-in, the processor of the electronic device can be configured to move the AOD screen on the display by a specified gap at specified intervals. However, when a foldable electronic device is in a folded state in low-power display mode, it may not be easy to move the AOD screen on the display. In addition, when displaying content that may cause burn-in of the AOD screen, it may not be easy to reduce burn-in.

[0007] Embodiments of the present disclosure provide a method for reducing a burn-in phenomenon when displaying various AOD screens on a foldable electronic device for a specified period of time or longer, and an electronic device to which the method is applied.

[0008] Technical Solution

[0009] According to an example embodiment of the present disclosure, a method for reducing display degradation of an electronic device includes: determining whether the display is in a low-power display mode for displaying an screen-off display (AOD) screen; identifying content of a first screen displayed on the display based on the display displaying the AOD screen; detecting a folding angle of the display; generating a second screen by reorganizing the first screen based on the folding angle; and displaying the second screen on the display.

[0010] According to an exemplary embodiment of the present disclosure, a foldable electronic device including a folded state, a flat state, and an intermediate state between the folded state and the flat state includes: a display configured to display a screen; a sensor module including at least one sensor configured to obtain a folding angle of the display; and a processor operably connected to the display and the sensor module. The processor is configured to: determine whether the display is in a low-power display mode for displaying an AOD (Audio-Off Display) screen; identify content of a first screen displayed on the display based on the display displaying the AOD screen; detect the folding angle of the display using the sensor module; generate a second screen by reorganizing the first screen based on the folding angle; and control the display to display the second screen on the display.

[0011] Technical Effects

[0012] According to various exemplary embodiments of the present disclosure, a foldable electronic device can reorganize the contents of an AOD screen based on the folding angle of the display in low-power display mode. As the folding angle of the display changes, the foldable electronic device can display a new screen, thereby reducing display burn-in.

[0013] Furthermore, according to various exemplary embodiments of the present disclosure, a foldable electronic device can recognize the content displayed on a display and restructure the screen according to the degree of aging. When the degree of aging is greater than or equal to a specified degree, the foldable electronic device can dynamically change the displayed content, thereby reducing the aging of the display.

[0014] Furthermore, the present disclosure can provide various effects determined directly or indirectly. BRIEF DESCRIPTION OF THE DRAWINGS

In various embodiments, at least one of the components (e.g., the display device 160 or the camera module 180) may be omitted from the electronic device 101, or one or more other components may be added to the electronic device 101. In various embodiments, some of the components may be implemented as a single integrated circuit. For example, the sensor module 176 (eg, a fingerprint sensor, an iris sensor, or an illumination sensor) may be implemented as embedded in the display device 160 (eg, a display).

[0044] The processor 120 may run, for example, software (e.g., program 140) to control at least one other component of the electronic device 101 connected to the processor 120 (e.g., a hardware component or a software component), and may perform various data processing or calculations. According to an embodiment, as at least part of the data processing or calculation, the processor 120 may load commands or data received from another component (e.g., sensor module 176 or communication module 190) into the volatile memory 132, process the commands or data stored in the volatile memory 132, and store the resulting data in the non-volatile memory 134.

Depending on the embodiment, the connection end 178 may include, for example, an HDMI connector, a USB connector, an SD card connector, or an audio connector (e.g., a headphone connector).

[0055] The haptic module 179 may convert the electrical signal into mechanical stimulation (eg, vibration or motion) or electrical stimulation that can be recognized by the user via his sense of touch or kinesthetic sense. According to an embodiment, the haptic module 179 may include, for example, a motor, a piezoelectric element, or an electrical stimulator.

[0057] The power management module 188 may manage power supply to the electronic device 101. According to an embodiment, the power management module 188 may be implemented as, for example, at least a part of a power management integrated circuit (PMIC).

[0058] The battery 189 can supply power to at least one component of the electronic device 101. According to an embodiment, the battery 189 can include, for example, a primary cell which is not rechargeable, a secondary cell which is rechargeable, or a fuel cell.

[0059] The communication module 190 can support establishing a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device 101 and an external electronic device (e.g., the electronic device 102, the electronic device 104, or the server 108) and performing communication via the established communication channel. The communication module 190 can include one or more communication processors that are operable independently from the processor 120 (e.g., an application processor (AP)) and supports a direct (e.g., wired) communication or a wireless communication. According to an embodiment, the communication module 190 can 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 can 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 cellular network, the Internet, or a computer network (e.g., LAN or wide area network (WAN)). These various types of communication modules can be implemented as a single component (e.g., a single chip) or multiple components (e.g., multiple chips) separate from each other. The wireless communication module 192 can 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., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module 196.

[0060] Antenna module 197 can transmit or receive signals or power to or from the outside of electronic device 101 (e.g., an external electronic device). Depending on the embodiment, antenna module 197 may include an antenna comprising a radiating element comprising a conductive material or conductive pattern formed in or on a substrate (e.g., a PCB). Depending on the embodiment, antenna module 197 may include multiple antennas. In this case, at least one antenna suitable for the communication scheme used in a communication network (such as first network 198 or second network 199) may be selected from the multiple antennas by, for example, communication module 190 (e.g., wireless communication module 192). Signals or power can then be transmitted or received between communication module 190 and the external electronic device via the selected at least one antenna. Depending on the embodiment, additional components (e.g., a radio frequency integrated circuit (RFIC)) in addition to the radiating element may also be formed as part of antenna module 197.

[0061] At least some of the above components can be connected to each other via an inter-peripheral communication scheme (e.g., a bus, general-purpose input output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)) and communicatively transmit signals (e.g., commands or data) therebetween.

[0062] 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 connected to the second network 199. Each of the electronic device 102 and the electronic device 104 may be a device of the same type as the electronic device 101, or a device of a different type than the electronic device 101. According to an embodiment, all or some operations to be executed on the electronic device 101 may be executed on one or more of the external electronic device 102, the external electronic device 104, or the server 108. For example, if the electronic device 101 should automatically execute a function or service or should execute a function or service in response to a request from a user or another device, the electronic device 101 may request the one or more external electronic devices to execute at least part of the function or service instead of executing the function or service, or the electronic device 101 may request the one or more external electronic devices to execute at least part of the function or service in addition to executing the function or service. The one or more external electronic devices that receive the request may execute at least a portion of the requested function or service, or execute another function or service related to the request, and transmit the result of the execution to the electronic device 101. The electronic device 101 may provide the result as at least a partial response to the request, either with or without further processing the result. To this end, for example, cloud computing technology, distributed computing technology, or client-server computing technology may be used.

The DDI 230 may receive image information including image data or image control signals corresponding to commands for controlling image data from another component of the electronic device 101 via the interface module 231. For example, depending on an embodiment, the image information may be received from the processor 120 (e.g., the main processor 121 (e.g., an application processor)) or the auxiliary processor 123 (e.g., a graphics processing unit), wherein the auxiliary processor 123 operates independently of the functions of the main processor 121. The DDI 230 may communicate with, for example, the touch circuit 150 or the sensor module (e.g., including at least one sensor) 176 via the interface module 231. DDI 230 may also store at least a portion of the received image information in memory 233, for example, on a frame-by-frame basis.

Depending on the embodiment, for example, the pre-processing or post-processing may be performed based at least in part on one or more characteristics of the image data or one or more characteristics of display 210. Mapping module 237 may generate voltage or current values ​​corresponding to the image data pre-processed or post-processed by image processing module 235. Depending on the embodiment, for example, the generation of the voltage or current values ​​may be performed based at least in part on one or more attributes of the pixels (e.g., the pixel array (such as an RGB stripe or pentile structure) or the size of each sub-pixel). For example, at least some pixels of display 210 may be driven based at least in part on the voltage or current values, thereby displaying visual information (e.g., text, an image, or an icon) corresponding to the image data via display 210.

[0064] According to an embodiment, the display device 160 may further include a touch circuit 250. The touch circuit 250 may include a touch sensor 251 and a touch sensor IC 253 for controlling the touch sensor 251. The touch sensor IC 253 may control the touch sensor 251 to sense a touch input or a hovering input directed to a specific location on the display 210. To this end, for example, the touch sensor 251 may detect (e.g., measure) a signal (e.g., voltage, amount of light, resistance, or one or more amounts of charge) corresponding to the specific location on the display 210. The touch circuit 250 may provide input information (e.g., position, area, pressure, or time) indicating the touch input or hovering input detected by the touch sensor 251 to the processor 120. According to an embodiment, at least a portion of the touch circuit 250 (e.g., the touch sensor IC 253) may be formed as part of the display 210 or the DDI 230, or as part of another component located outside the display device 160 (e.g., the auxiliary processor 123).

[0065] Depending on the embodiment, the display device 160 may further include at least one sensor (e.g., a fingerprint sensor, an iris sensor, a pressure sensor, or an illumination sensor) of the sensor module 176, or a control circuit for the at least one sensor. In such a case, the at least one sensor or the control circuit for the at least one sensor may be embedded in a portion of a component of the display device 160 (e.g., the display 210, the DDI 230, or the touch circuit 150). For example, when the sensor module 176 embedded in the display device 160 includes a biometric sensor (e.g., a fingerprint sensor), the biometric sensor may acquire biometric information (e.g., a fingerprint image) corresponding to a touch input received via a portion of the display 210. As another example, when the sensor module 176 embedded in the display device 160 includes a pressure sensor, the pressure sensor may acquire pressure information corresponding to a touch input received via a partial area or the entire area of ​​the display 210. Depending on the embodiment, the touch sensor 251 or the sensor module 176 may be disposed between pixels in a pixel layer of the display 210, or above or below the pixel layer.

For example, the posture of the first shell structure 310 may be sensed according to the acceleration sensor of the first motion sensor 340, and the gesture of the first shell structure 310 may be sensed according to the angular velocity sensor of the first motion sensor 340. The first motion sensor 340 may generate first motion data based on the sensed posture and gesture of the first shell structure 310. The first motion sensor 340 may transmit the generated first motion data to the processor (e.g., Figure 1 The processor 120 of the first housing structure 310 may be provided with a magnet 342 in at least a portion of the first housing structure 310 adjacent to the hinge structure 360. The magnet 342 may radiate magnetic force to the outside. The magnet 342 may be used to sense the relative positional relationship between the first housing structure 310 and the second housing structure 320.

[0076] In an embodiment, a second motion sensor 350 and a magnetic sensor 352 may be disposed in at least a portion of the second housing structure 320. The second motion sensor 350 may be implemented as a combination of at least two of an acceleration sensor, an angular velocity sensor, and / or a geomagnetic sensor. The second motion sensor 350 may sense the posture and gestures of the second housing structure 320. For example, the posture of the second housing structure 320 may be sensed based on the acceleration sensor of the second motion sensor 350, while the gestures of the second housing structure 320 may be sensed based on the angular velocity sensor of the second motion sensor 350. The second motion sensor 350 may generate second motion data based on the sensed posture and gestures of the second housing structure 320. The second motion sensor 350 may transmit the generated second motion data to the processor 120 of the electronic device 101. The magnetic sensor 352 may be disposed in at least a portion of the second housing structure 320 adjacent to the hinge structure 360. The magnetic sensor 352 may sense magnetism. The magnetic sensor 352 can sense the relative positional relationship between the first housing structure 310 and the second housing structure 320 based on the sensed magnetic force. For example, the magnetic sensor 352 can detect sensing data related to the folding angle between the first housing structure 310 and the second housing structure 320 based on the sensed magnetic force. The magnetic sensor 352 can transmit the detected sensing data to the processor 120.

[0077] In an embodiment, the first motion sensor 340, the second motion sensor 350, and / or the magnetic sensor 352 may include a six-axis sensor and / or a digital Hall effect IC sensor. The six-axis sensor and / or the digital Hall effect IC sensor may include both hardware and software. The six-axis sensor and / or the digital Hall effect IC sensor may calculate raw data related to the folding angle of the first housing structure 310 and the second housing structure 320. The raw data related to the folding angle may be processed by a library of the processor 120. The processor 120 may calculate the folding angle of the first housing structure 310 and the second housing structure 320 by processing the raw data using a library implemented in source code.

[0078] Figure 4 FIG. 1 is a diagram showing an electronic device (eg, Figure 1 400 of the folded state of the electronic device 101).

[0079] In an embodiment, one or more components may be disposed on, or visually exposed to, the rear side of the electronic device 101. For example, one or more components or sensors including the rear camera assembly 372 and / or the proximity sensor 374 may be visually exposed through the second side 312 of the first housing structure 310. In another example, at least a portion of the sub-display 370 may be visually exposed through the second side 312 of the first housing structure 310.

[0080] In an embodiment, the magnets of the first housing structure 310 (eg, Figure 3 magnet 342) and a magnetic sensor of the second housing structure 320 (eg, Figure 3 The magnetic sensors 352 of the magnet 342 may at least partially face each other in the folded state of the electronic device 101. The magnetic sensors 352 may sense a change in the magnetic force radiated from the magnet 342 according to a change to the flat state and / or the folded state.

[0081] In an embodiment, the angle and / or distance between the first housing structure 310 and the second housing structure 320 may be determined based on whether the electronic device 101 is in a flat state (eg, Figure 3 state), folded state (for example, Figure 4 state) or an intermediate state (e.g. Figure 3 Status and Figure 4 The state between the states) changes.

[0082] Figure 5 is a diagram illustrating a method for reducing an electronic device (eg, Figure 1 The electronic device 101) has a display (eg, Figure 2 Flowchart 500 of an example method for degradation of a display 210).

[0083] In operation 10, the processor (eg, Figure 1 The processor 120 of the display 210 may determine whether the display 210 is in a low power display mode. The processor 120 may determine whether the display 210 is in a low power display mode for displaying an AOD screen.

[0084] In an embodiment, the AOD screen may be a screen that continuously displays information (e.g., time, date, battery level, and notifications) on the display 210 at low power while the screen of the display 210 is turned off. When the AOD screen is displayed, the user of the electronic device 101 can recognize information such as time, date, battery level, and notifications without turning on the screen of the display 210.

[0085] In an embodiment, when it is determined that the display 210 is in the low-power display mode (Operation 10-Yes), the processor 120 may proceed to Operation 20. When it is determined that the display 210 is in the general mode where the screen is turned on (Operation 20-No), the processor 120 may display the screen on the display 210 without proceeding to Operation 20.

[0086] In operation 20, the processor 120 of the electronic device 101 according to an embodiment may identify content of the first screen displayed on the display 210. For example, when the display 210 displays an AOD screen, the processor 120 may identify the type and / or characteristics of content displayed on the AOD screen.

[0087] In operation 30, the processor 120 of the electronic device 101 according to an embodiment may detect the folding angle of the display 210. The processor 120 may detect the folding angle of the display 210 from the first motion sensor (eg, Figure 3 The first motion sensor 340 receives the first motion data, and the second motion sensor (eg, Figure 3 The processor 120 may receive the second motion data from the magnetic sensor (e.g., Figure 3 The magnetic sensor 352 receives sensing data related to the folding angle of the first housing structure 310 and the second housing structure 320. The processor 120 can detect the folding angle of the display 210 based on the first motion data, the second motion data, and / or the received sensing data. The processor 120 can determine whether the folding angle of the display 210 has changed by detecting the folding angle of the display 210 at each specified period.

[0088] In operation 40, the processor 120 of the electronic device 101 according to an embodiment may generate a second screen by reorganizing the first screen based on the folding angle. In order to reduce degradation and / or aging of the display 210, the processor 120 may reorganize the content of the first screen to generate a second screen that causes a lower degree of degradation and / or aging of the display 210 than the first screen.

[0089] In an embodiment, the processor 120 may change the brightness, color, position, arrangement relationship and / or size of the content of the first screen while maintaining the type and / or content of the content of the first screen. For example, the processor 120 may change the font of the text included in the AOD screen, may shift the graphic content of the AOD screen to a specified gap, or may separate the graphic content and text of the AOD screen from each other.

[0090] In an embodiment, the processor 120 may sense operating characteristics of the display 210 that vary according to the folding angle of the display 210. For example, the processor 120 may sense pixels per inch (ppi), dots per inch (dpi), brightness, resolution, and / or power consumption of the display 210 that vary according to the folding angle of the display 210. The processor 120 may generate a second screen by changing display characteristics of the display 210 according to the operating characteristics of the display 210.

[0091] In operation 50, the processor 120 of the electronic device 101 according to an embodiment may display a second screen on the display 210. The processor 120 may reduce degradation and / or aging of the display 210 by displaying the second screen when displaying the AOD screen, the second screen containing content including substantially the same type and / or content as the first screen, and causing the degree of degradation and / or aging of the display 210 to be lower than that of the first screen. The second screen may be a screen obtained by changing the brightness, color, position, arrangement relationship and / or size of the content of the first screen while maintaining the type and / or content of the content of the first screen. The second screen may be a screen obtained by changing the average brightness and / or maximum brightness to a specified threshold brightness or lower. The second screen may be a screen obtained by changing the size of the content of the AOD screen to a specified threshold or smaller.

[0092] In an embodiment, the processor 120 may calculate the brightness, color, position, arrangement relationship and / or size of the content of the first screen, and may display the second screen obtained by changing the first screen when it is determined that the degree of degradation and / or aging caused by the first screen is greater than or equal to a specified degree. For example, the processor 120 may change the font of the text included in the AOD screen to a thin font, may move the gap between the graphic content items of the AOD screen to a specified gap, or may split the graphic content and text of the AOD screen and display them.

[0093] Figure 6 is a diagram 600 illustrating a low power display mode of the display 210 of the electronic device 101 according to various embodiments.

[0094] In an embodiment, the processor of the electronic device 101 (eg, Figure 1 The processor 120) can support: an active state or a wake-up state in which a user can intensively use the functions of the electronic device 101; and an inactive state or a sleep state in which the processor waits for the user to use the electronic device 101.

[0095] In an embodiment, in an active state or a wake-up state, the processor 120 may perform control so that a plurality of hardware modules and / or software modules included in the electronic device 101 operate in a general mode. The processor 120 may control a power management module (e.g., Figure 1 power management module 188) so that multiple hardware modules and / or software modules can run off the battery in a normal mode (e.g., Figure 1 In the general mode, the plurality of hardware modules and / or software modules may perform functions without limitation. For example, in the active state or the awake state, the processor 120 may control the display 210 to receive the rated power and be turned on to display an application (e.g., Figure 1 146) execution screen or receive a user's touch input while maintaining a specific sensitivity.

[0096] In an embodiment, in an inactive state or a sleep state, the processor 120 may perform control so that a plurality of hardware modules and / or software modules included in the electronic device 101 operate in a low power mode. The processor 120 may control the power management module 188 so that the plurality of hardware modules and / or software modules receive minimum power from the battery 189 in the low power mode. In the low power mode, the plurality of hardware modules and / or software modules may be disabled or only perform specified limited functions. In an inactive state or a sleep state, the processor 120 may control the plurality of hardware modules and / or software modules so that the plurality of hardware modules and / or software modules only perform limited functions. In an inactive state or a sleep state, by suppressing information processing or arithmetic operations of the plurality of hardware modules and / or software modules, the power consumption of the plurality of hardware modules and / or software modules may be reduced, and the amount of time the battery 189 is used may be increased. According to an embodiment, the processor 120 may control the display driver IC (e.g., Figure 2 The processor 120 may control the display driver IC 230 so that the display 210 operates in an inactive state or a sleep state in a low power mode (or, operates in a low power display mode). For example, the processor 120 may control the display driver IC 230 so that the display 210 outputs content on the first area 611 of the display 210 in an inactive state or a sleep state, for example, text and / or images representing a digital clock, date and / or battery status. In another example, the processor 120 may control the display driver IC 230 so that the display 210 outputs various types of graphical user interface (GUI) objects, for example, icons, on the second area 612 of the display 210. The text, images and / or GUI objects included in the first area 611 and the second area 612 may be included in the AOD screen.

[0097] In an embodiment, text, images and / or GUI objects included in the first area 611 and the second area 612 of the display 210 of the electronic device 101 running in an inactive state or a sleep state can be displayed as a specified first color (e.g., white). Pixels displaying text, images and / or GUI objects included in the first area 611 and the second area 612 can emit light of the first color. The background area other than the first area 611 and the second area 612 can be set to a second color (e.g., black). The pixels set in the background area can be configured to have a second color. For example, when the display 210 includes an organic light emitting diode (OLED) panel, the pixels set in the background area can be turned off.

[0098] According to an embodiment, the text, image, and / or GUI object included in the first area 611 and the second area 612 of the display 210 can be moved up and down and / or left and right. The AOD screen can be moved periodically or non-periodically. When the AOD screen is moved, the degradation and / or aging of the pixels displaying the text, image, and / or GUI object in the first area 611 and the second area 612 can be reduced.

[0099] According to an embodiment, when the display 210 operates in an inactive state or a sleep state (or operates in a low-power display mode), it can sense a user's touch input on a GUI object included in the second area 612 while consuming minimal power. When a user's touch input on a GUI object included in the second area 612 is sensed, the processor 120 can switch the display 210 to an active state or a wake-up state.

[0100] In an embodiment, the AOD screen may include: a first object including text and / or an image representing a clock, date, and / or battery status; and a second object including a notification received by the electronic device 101 or transmitted to the user by the electronic device 101. The first object may be displayed on the first area 611. For example, the first object may be content such as text and / or an image representing a digital clock, date, and / or battery status displayed on the first area 611. The second object may be displayed on the second area 612. For example, the second object may be various types of GUI objects, such as icons.

[0101] In an embodiment, the processor 120 may be configured to determine whether an event occurs for switching the processor 120 to a sleep state. The processor 120 may determine whether an event occurs for transitioning to a low power display mode. For example, when the low power display mode is activated, the electronic device 101 may execute the low power display mode when the processor 120 is switched to a sleep state. Figure 5In the embodiment, the operation 10 of determining whether the display 210 is in the low power display mode may include an operation of determining, by the processor 120 of the electronic device 101, whether an event for switching the processor 120 to a sleep state occurs.

[0102] FIG. 7A is a view 700 illustrating example first contents 710 , 720 , and 730 of a first screen displayed on the display 210 in the low power display mode according to various embodiments.

[0103] In an embodiment, an electronic device (e.g., Figure 1 A processor (eg, Figure 1 The processor 120 of the embodiment may be configured to identify running applications (e.g., Figure 1 The processor 120 may identify the type and / or form of the first contents 710, 720, and 730 displayed on the display 210 according to the execution of the application 146. When the event of transitioning to the low power display mode occurs, the processor 120 may identify the list of applications 146. Figure 5 , the operation 20 of identifying the content of the first screen displayed on the display 210 may include an operation of identifying, by the processor 120 of the electronic device 101, a list of running applications.

[0104] In an embodiment, when the display 210 of the electronic device 101 is oriented in a portrait orientation, the processor 120 may display an AOD screen including first content 710, 720, and 730. The first content 710, 720, and 730 may be content displayed corresponding to portrait viewing. When the display 210 of the electronic device 101 is oriented in a portrait orientation, the processor 120 may determine that the electronic device 101 is placed in a portrait orientation, so that the user visually recognizes that the display 210 is in a portrait orientation.

[0105] In an embodiment, the first content 710, 720 and 730 of the AOD screen displayed on the display 210 may be of various types and / or forms. For example, as shown in FIG7A , the first content 710, 720 and 730 of the AOD screen displayed on the display 210 may include a date and battery level 710, a digital clock 720 and at least one notification icon 730. For example, at least one notification icon 730 may include an icon for notifying the number of missed calls and / or an icon for notifying the number of received messages. In another example, the content of the AOD screen may include an analog clock, a world clock, a calendar, a wallpaper and / or an image. The processor 120 may generate a display driver IC (e.g., Figure 2 The display driver IC 230 of the display 210 receives information about the type, content and / or form of the first contents 710, 720 and 730 of the AOD screen displayed on the display 210.

[0106] FIG7B is a view 750 illustrating second contents 760 , 770 , 780 , and 790 of a first screen displayed on the display 210 in the low power display mode according to various embodiments.

[0107] In an embodiment, the processor 120 may display an AOD screen including second content 760, 770, 780, and 790 when the display 210 of the electronic device 101 is facing a landscape orientation. The second content 760, 770, 780, and 790 may be content displayed corresponding to viewing in a landscape orientation. When the display 210 of the electronic device 101 is facing a landscape orientation, the processor 120 may determine that the electronic device 101 is placed in a landscape orientation, so that the user visually recognizes that the display 210 is in a landscape orientation.

[0108] In an embodiment, the second content 760, 770, 780 and 790 of the AOD screen displayed on the display 210 may have various types and / or forms. For example, as shown in Figure 7B, the second content 760, 770, 780 and 790 of the AOD screen displayed on the display 210 may include an analog clock 760, a date and battery level 770, at least one notification icon 780 and a fingerprint recognition icon 790. In another example, the content of the AOD screen may include a digital clock, a world clock, a calendar, a wallpaper and / or an image. The processor 120 may receive information about the type, content and / or form of the second content 760, 770, 780 and 790 of the AOD screen displayed on the display 210 from the display driver IC 230.

[0109] Figure 8 FIG. 1 is a diagram illustrating a method for detecting an electronic device (eg, Figure 1 The electronic device 101 according to the embodiment may include a sensor module (e.g., including at least one sensor) 176, a processor (e.g., including a processing circuit) 120, a display driver integrated circuit (DDI) 230 (e.g., including a display driver integrated circuit (DDI)). Figure 2 display driver integrated circuit 230), display 210 and memory 130.

[0110] In an embodiment, the sensor module 176 may include at least one sensor and detect sensing data related to the folding angle of the display 210, which is the angle formed by the opposite sides of the display 210 at the folding portion when the display 210 is folded. For example, the sensor module 176 may obtain sensing data from at least one of a motion sensor or a magnetic sensor. The sensor module 176 may transmit the obtained sensing data to the processor 120. The processor 120 may include various processing circuits and calculate the folding angle of the display 210 based on the sensing data. The processor 120 may periodically obtain sensing data from at least one of the motion sensor or the magnetic sensor included in the sensor module 176. The processor 120 may periodically determine whether the folding angle of the display 210 has changed based on the sensing data. Figure 5 In the embodiment, the operation 30 of detecting the folding angle of the display 210 may include the operation of periodically obtaining sensing data by the processor 120 using the sensor module 176 including a motion sensor and / or a magnetic sensor.

[0111] In an embodiment, based on the change in the sensing data, the processor 120 may calculate the change in the form of the content displayed on the display 210 according to the change in the folding angle. The processor 120 may calculate how the form of the content displayed to the user on the display 210 changes when the folding angle changes. Figure 5 In the embodiment, the operation 30 of detecting the folding angle of the display 210 may include an operation of calculating, by the processor 120, a change in the form of content displayed on the display 210 in response to a change in the folding angle.

[0112] In an embodiment, the processor 120 may sense whether the electronic device 101 is in a flat state, a folded state, and / or an intermediate state based on the sensing data. The processor 120 may sense whether the electronic device 101 changes from one of the flat state, the folded state, and / or the intermediate state to another state. When recognizing that the state of the electronic device 101 has changed, the processor 120 may transmit information about the display area corresponding to the changed state of the electronic device 101 to the application (e.g., Figure 1 Application 146).

[0113] In an embodiment, when a change in the state of the electronic device 101 is recognized based on the sensing data, the processor 120 may transmit information about a display area corresponding to the changed state of the electronic device 101 to an application 146 for which continuity is set among the running applications 146. The processor 120 may compare first display area information of the display 210 depending on the previous state of the electronic device 101 and second display area information of the display 210 depending on the changed state of the electronic device 101. For example, when the state of the electronic device 101 is changed, the resolution of the content displayed on the display 210 may be changed. In order to notify the change in resolution based on the sensing data, the processor 120 may include information about the resolution of the content displayed on the display 210 in the first display area information and the second display area information, and may store the information in the memory 130.

[0114] Figure 9 FIG. 1 is a diagram illustrating a method for detecting an electronic device (eg, Figure 1 The electronic device 101) has a display (eg, Figure 2 FIG. 9 is a block diagram of components for controlling a folding angle of a display 210 of an electronic device 101. The electronic device 101 according to an embodiment may include an angle sensor 911, a distance sensor 912, a gyro sensor 913, an input framework 920, and a folding angle change event controller 930.

[0115] In an embodiment, the angle sensor 911, the distance sensor 912, and the gyro sensor 913 can obtain the folding angle of the electronic device 101, the first housing structure (eg, Figure 3 The first shell structure 310) and the second shell structure (for example, Figure 3 and the distance between the second housing structure 320 and the display (eg, Figure 2 The angle sensor 911, the distance sensor 912, and the gyro sensor 913 may be connected to the input framework 920 via a sensor driver (not shown). The sensor driver (not shown) may be a software module for controlling the angle sensor 911, the distance sensor 912, and the gyro sensor 913. The angle sensor 911, the distance sensor 912, and the gyro sensor 913 may transmit the sensing data to the input framework 920.

[0116] In an embodiment, the input framework 920 may receive sensing data for measuring the flat state and / or folded state of the electronic device 101 from the angle sensor 911, the distance sensor 912, and the gyroscope sensor 913. The input framework 920 may determine the flat state and / or folded state of the electronic device 101 based on the sensing data. The input framework 920 may transmit information related to the state of the electronic device 101 to the folding angle change event controller 930. For example, the input framework 920 may transmit a first signal notifying the folding angle change event controller 930 that the electronic device 101 is in the flat state. In another example, the input framework 920 may transmit a second signal notifying the folding angle change event controller 930 that the electronic device 101 is in the folded state.

[0117] In an embodiment, the folding angle change event controller 930 may receive an event related to a change in the flat state and / or folded state of the electronic device 10. The folding angle change event controller 930 may control the display 210 and the sub-display (eg, Figure 4 turning on and / or off the sub-display 370).

[0118] In an embodiment, the folding angle change event controller 930 may be configured to generate an event based on the currently running application (e.g., Figure 1 146), pre-stored in memory (e.g., Figure 1 Activation and / or deactivation of the display 210 is performed in the memory 130) with a policy corresponding to the state change of the electronic device 101 and / or the activation or deactivation permission state of the display 210.

[0119] Figure 10 FIG. 1 is a diagram showing an electronic device (eg, Figure 1 The electronic device 101) has a display (eg, Figure 2 FIG1000 illustrates an example variation of a folding angle of the display 210 .

[0120] In an embodiment, the first housing structure 310 and the second housing structure 320 of the electronic device 101 can be folded using the hinge structure 360 so as to face each other. The first housing structure 310 and the second housing structure 320 can have various folding angles, e.g., a first folding angle θ1, a second folding angle θ2, a third folding angle θ3, and a fourth folding angle θ4, with respect to the hinge structure 360. The first folding angle θ1, the second folding angle θ2, the third folding angle θ3, and the fourth folding angle θ4 can be angles not less than 0 degrees and not more than 180 degrees. For example, the first folding angle θ1 can be about 45 degrees, the second folding angle θ2 can be about 75 degrees, the third folding angle θ3 can be about 120 degrees, and the fourth folding angle θ4 can be about 150 degrees. The first folding angle θ1, the second folding angle θ2, the third folding angle θ3, and the fourth folding angle θ4 can indicate a case where the electronic device 101 is in an intermediate state. When the folding angle is 0 degrees, the electronic device 101 can be in a folded state, and when the folding angle is 180 degrees, the electronic device 101 can be in a flat state. As the first housing structure 310 and the second housing structure 320 of the electronic device 101 are folded and unfolded, the display 210 can be folded and unfolded. The folding angle formed by the first housing structure 310 and the second housing structure 320 can be substantially the same as the folding angle of the display 210.

[0121] In an embodiment, as the folding angle of the display 210 changes, the electronic device 101 can change the AOD screen displayed on the display 210. In an embodiment, in order to reduce degradation and / or aging of the display 210, the electronic device 101, when changing the AOD screen of the display 210, can change the AOD screen to an AOD screen that causes less degradation and / or aging of the display 210.

[0122] In an embodiment, the display 210 of the electronic device 101 can have a foldable shape structure that is connected inside and displayed outside. The display 210 having the foldable shape structure can display an AOD screen through a portion other than a portion that is folded when facing each other. For example, the display 210 having the foldable shape structure can display an AOD screen through an area exposed to the outside when the electronic device 101 is in a folded state. In order to reduce the phenomenon of degradation and / or aging occurring in the display 210 that displays an AOD screen for a long time, a processor (e.g., the processor 120 of FIG. 1) can change the display characteristics of the display 210 when the folding angle of the display 210 changes.

Figure 1 ​FIG11 is a block diagram 1100 of components for degrading a display 210 of an electronic device 101 according to an embodiment of the present invention. The electronic device 101 according to an embodiment may include hardware 1110, a kernel 1120, a library 1130, a framework 1140, and an application 146.

[0124] In an embodiment, the hardware 1110 may include a sensor module (e.g., Figure 1 The electronic device 101 may recognize a state change of the electronic device 101 based on the sensor module 176 and the display 210. In an embodiment, the electronic device 101 may display an AOD screen obtained by reorganizing the content on the display 210.

[0125] In an embodiment, the core 1120 may include a state management module 1121 and a DDI 230. In an embodiment, the state management module 1121 may identify a state change of the electronic device 101 based on the sensor module 176. In an embodiment, the electronic device 101 may display a screen on the display 210 using the DDI 230.

[0126] In an embodiment, when a state change of the electronic device 101 is recognized by the sensor module 176, the state management module 1121 may activate at least a portion of the display area of ​​the display 210. For example, the state management module 1121 may activate at least a portion of the display area of ​​the display 210 by sending an activation signal to the DDI 230.

[0127] In an embodiment, the state management module 1121 may activate at least a portion of the display area of ​​the display 210 based on a change in the state of the electronic device 101 and / or a change in the folding angle. For example, when the electronic device 101 changes from a folded state to a flat state or the size of the folding angle increases, the state management module 1121 may activate a display area (e.g., a first display area) of the display 210 that corresponds to the flat state. In another example, when the electronic device 101 changes from a flat state to a folded state or the size of the folding angle decreases, the state management module 1121 may activate a display area (e.g., a second display area) of the display 210 that corresponds to the folded state. The state management module 1121 may manage the folding state of the display 210, for example, folding inward and / or folding outward.

[0128] In an embodiment, the state management module 1121 may calculate the folding angle of the display 210 based on the sensing data received from the sensor module 176. The state management module 1121 may transfer the calculated folding angle of the display 210 to the window manager 1142 and / or the anti- / reduction burn-in management module 1143 (as used herein, the term "anti-" may refer to preventing and / or reducing). In a normal operating state, the state management module 1121 may transfer the folding angle of the display 210 to the anti-burn-in module 1143 through the window manager 1142. In order to minimize and / or reduce current consumption, or to adjust the AOD in a sleep state, the state management module 1121 may directly transfer the folding angle of the display 210 to the anti-burn-in module 1143, but not through the window manager 1142.

[0129] In an embodiment, the library 1130 may include a layer composition unit 1131. The layer composition unit 1131 may composite multiple layers, including content to be displayed on the display 210. For example, the layer composition unit 1131 may be a display composition system (surface flinger). The layer composition unit 1131 may provide data representing the composited multiple layers to the DDI 230.

[0130] In an embodiment, the framework 1140 may include a drawing manager 1141, a window manager 1142, and an anti-aging management module 1143. The anti-aging management module 1143 may be included in a processor (e.g., Figure 1 The anti-aging management module 1143 may be included in the window manager 1142.

[0131] In an embodiment, the drawing manager 1141 may draw at least one layer based on the resolution of the display area of ​​the display 210. The drawing manager 1141 may be a program, such as a View TM The drawing manager 1141 may draw the screen by the application 146 based on the resolution of the second display area of ​​the display 210 .

[0132] In an embodiment, when a change in the state of the electronic device 101 is recognized by the state management module 1121, the window manager 1142 may transmit information about the display area corresponding to the changed state of the electronic device 101 to the anti-aging management module 1143. For example, when a change in the folded state of the electronic device 101 is recognized, the window manager 1142 may transmit information about the display area corresponding to the changed folded state of the electronic device 101 to the anti-aging management module 1143.

[0133] In an embodiment, the anti-aging management module 1143 may receive information that the folding state of the electronic device 101 has changed through the state management module 1121 and / or the window manager 1142. In a normal operating state, the anti-aging management module 1143 may receive information from the window manager 1142 that the folding state of the electronic device 101 has changed. To minimize and / or reduce current consumption, or to adjust the AOD in a sleep state, the anti-aging management module 1143 may receive information from the state management module 1121 that the folding state of the electronic device 101 has changed. Based on the folding angle of the electronic device 101, the anti-aging management module 1143 may reorganize the content of the AOD screen to reduce degradation and / or aging of the display 210. For example, based on the folding angle of the display 210, the anti-aging management module 1143 may reorganize the AOD screen associated with the running first application 1151 to display the AOD screen. The anti-aging management module 1143 may notify the running first application 1151 of the change in the folding angle of the display 210 so that the AOD screen can be reorganized. The anti-aging management module 1143 may change the display characteristics of the display 210 based on the folding angle, may analyze the physical characteristics of the display 210, and may determine whether the degree of aging of the display 210 is less than or equal to a threshold.

[0134] In an embodiment, the application 146 may include a running first application 1151. The first application 1151 may draw at least one layer according to the resolution of the display area of ​​the display 210. The screen of the first application 1151 may be a screen for displaying an AOD screen. At least one layer may be an AOD screen executed in the first application 1151. For example, the first application 1151 may use a graphics interface such as a View TM The drawing manager 1141 of the display 210 draws at least one layer corresponding to the resolution of the display area of ​​the display 210. Accordingly, the first application 1151 can draw the AOD screen.

[0135] Figure 12 is a diagram illustrating a method for using an electronic device (eg, Figure 1 The electronic device 101) has a display (eg, Figure 2 Flowchart 1200 of an example method for generating a second screen by using a folded corner of the display 210).

[0136] In operation 1210, the processor (eg, Figure 1 processor 120) and / or an anti-aging management module (e.g., Figure 11The processor 120 and / or the anti-aging management module 1143 may analyze the display characteristics of the display 210 based on the folding angle. The processor 120 and / or the anti-aging management module 1143 may analyze the display characteristics or display properties of the display 210, such as brightness and font, based on the folding angle of the electronic device 101. Operation 1210 may be included in operation 40 of generating the second screen by reorganizing the first screen.

[0137] In operation 1220, the processor 120 and / or the anti-aging management module 1143 of the electronic device 101 according to an embodiment may analyze the physical properties of the display 210. The processor 120 and / or the anti-aging management module 1143 may analyze and / or predict physical properties, for example, hardware physical property information of the display 210, to suppress degradation and / or aging of the display 210. Operation 1220 may be included in operation 40 of generating the second screen by reorganizing the first screen.

[0138] In operation 1230, the processor 120 and / or the anti-aging management module 1143 of the electronic device 101 according to an embodiment may determine whether the degree of aging of the display 210 is less than or equal to a threshold. The processor 120 and / or the anti-aging management module 1143 may predict the degree of aging caused by the AOD screen displayed on the display 210 based on the display characteristics of the AOD screen. The processor 120 and / or the anti-aging management module 1143 may predict whether the aging test is passed or failed based on the predicted degree of aging. When the predicted degree of aging caused by the AOD screen displayed on the display 210 is less than or equal to a specified threshold, the test result may be "passed aging." When the predicted degree of aging caused by the AOD screen displayed on the display 210 exceeds a specified threshold, the test result may be "failed aging." When the degree of aging of the display 210 is less than or equal to the threshold (operation 1230 - yes), the processor 120 and / or the anti-aging management module 1143 may determine that the aging test is passed and may proceed to operation 1240. When the aging degree of the display 210 exceeds the threshold (operation 1230-No), the processor 120 and / or the anti-aging management module 1143 may determine that aging has failed and may return to operation 1210. Operation 1230 may be included in operation 40 of generating the second screen by recombining the first screen.

[0139] In operation 1240, the processor 120 and / or the anti-aging management module 1143 of the electronic device 101 according to an embodiment may generate a second screen by changing the display characteristics. When it is determined that the generation of the second screen results in a degree of aging less than or equal to a threshold, the processor 120 and / or the anti-aging management module 1143 may generate the second screen by changing the display characteristics in response to the aging qualification test result. For example, the processor 120 may generate the second screen by reducing the size of the content on the first screen by a predetermined ratio. In another example, the processor 120 may generate the second screen by hiding at least a portion of a plurality of content items, such as a clock, battery, date, and notification displayed on the first screen. In another example, the processor 120 may generate the second screen by splitting and repositioning the content displayed on the first screen. Operation 1240 may be included in operation 40 of generating the second screen by reorganizing the first screen.

[0140] Figure 13 FIG. 1 is a diagram showing an electronic device (eg, Figure 1 A view 1300 of a drawing area 1310 and a moving area 1320 of a display 210 of an electronic device 101).

[0141] In an embodiment, the drawing area 1310 may be an area where the display 210 displays the content included in the AOD screen when the AOD screen is displayed. The drawing area 1310 may have a first length D1 in a first direction (e.g., a horizontal direction or an X-axis direction). The first length D1 may be no less than approximately 250 dots (dp) and no more than approximately 300 dots. The drawing area 1310 may have a second length D2 in a second direction (e.g., a vertical direction or a Y-axis direction). The second length D2 may be no less than approximately 300 dp and no more than approximately 350 dp.

[0142] In an embodiment, the mobile area 1320 may be an area of ​​the display 210 that can move content included in the AOD screen when the AOD screen is displayed. The mobile area 1320 may have a third length D3 in the first direction. The third length D3 may be no less than approximately 300 dp and no more than approximately 320 dp. The mobile area 1320 may have a fourth length D4 in the second direction. The fourth length D4 may be no less than approximately 400 dp and no more than approximately 500 dp.

[0143] In an embodiment, the movement region 1320 may include the drawing region 1310. The area of ​​the movement region 1320 may be larger than the area of ​​the drawing region 1310. The movement region 1320 may be longer in the second direction than the drawing region 1310 by a fifth length D5. The movement region 1320 may be longer in the first direction than the drawing region 1310 by a sixth length D6.

[0144] In an embodiment, the moving area 1320 may be set as a partial area of ​​the display 210. The moving area 1320 may be an area spaced inwardly from the edge of the display 210 by a seventh length D7 in the first direction. The seventh length D7 may be not less than about 20 dp and not more than about 30 dp.

[0145] In an embodiment, the drawing area 1310 may be periodically or non-periodically moved by a specified distance within the movement area 1320. By moving the drawing area 1310 within the movement area 1320, degradation and / or aging of the display 210 may be reduced.

[0146] In an embodiment, the processor of the electronic device 101 (eg, Figure 1 The processor 120 of the display 210 may be configured to change the display characteristics of the display 210 based on the folding angle. For example, when the display 210 displays the AOD screen, the processor 120 may variably set the drawing area 1310 and the moving area 1320 according to the folding angle and structure of the display 210 in the foldable shape. The processor 120 may change the display characteristics of the AOD screen according to the characteristics of the display 210 that can be variably changed to reduce degradation and / or aging of the display 210. The display characteristics of the AOD screen may include the brightness of the content of the AOD screen, the text font of the content of the AOD screen, the size of the content of the AOD screen, and the position information of the content of the AOD screen. For example, in the case of displaying the second screen by changing the text font of the content of the AOD screen (first screen) from a Gothic font or a bold font to a thin font, degradation and / or aging of the display 210 can be reduced compared to when displaying text such as a Gothic font or a bold font.

[0147] Figure 14 is a view 1400 illustrating half-folded modes 1410 and 1420 of the electronic device 101 according to various embodiments.

[0148] In an embodiment, the electronic device 101 can be folded in half about a folding axis B in half-folded modes 1410 and 1420. The half-folded modes 1410 and 1420 may be structures in which the display 210 is folded in half in an inwardly folded manner. In the half-folded modes 1410 and 1420, the display 210 can be folded so that the first area 1411 and the second area 1412 face each other.

[0149] In an embodiment, the electronic device 101 may display an AOD screen 1421 on the first area 1411. Based on the folding angle, the processor of the electronic device 101 (eg, Figure 1The processor 120 of the display 210 may reorganize the AOD screen 1421 to reduce degradation and / or aging of the display 210. The processor 120 may reorganize a screen related to the application 146 executing the AOD screen 1421 according to the folding angle of the display 210, and may display the screen on the display 210. For example, in the half-folding modes 1410 and 1420, the processor 120 may move the AOD screen 1421 to the first area 1411 so that the AOD screen 1421 does not overlap with the folding axis B.

[0150] Figure 15 FIG. 1 is a diagram illustrating a method for controlling an electronic device (eg, Figure 1 The electronic device 101) has a display (eg, Figure 2 The electronic device 101 according to the embodiment may include a display device 160, a kernel 1120, a framework 1140, and an application 146.

[0151] In an embodiment, the program of the electronic device 101 may include an operating system (OS) for controlling resources related to the electronic device 101, and / or various applications 146 driven on the operating system. For example, the operating system may include Android TM 、iOS TM , Windows TM , Symbian TM 、Tizen TM , or Bada TM At least some of the programs may be pre-installed on the electronic device at the time of manufacture, or may be downloaded or updated from an external electronic device or server in the user's usage environment.

[0152] In an embodiment, the application 146 may include a system application 1541 and a low-power display application 1542. For example, the low-power display application 1542 may be an application that displays an AOD screen. When the operating mode of the display 210 of the electronic device 101 is switched to the low-power display mode, the low-power display application 1542 may generate content to be displayed by the display device 160 while the display 210 operates in the low-power display mode.

[0153] In an embodiment, when a notification event occurs while the electronic device 101 is operating in the low-power display mode, the low-power display application 1542 may control the generation of content corresponding to the notification event. For example, the low-power display application 1542 may control the DDI 230 to display content on the display 210 according to the operating mode of the display 210 of the electronic device 101.

[0154] In an embodiment, the framework 1140 may provide various functions to the application 146, so that the application 146 uses functions or information provided by one or more resources of the electronic device 101. For example, the framework 1140 may include a window manager 1142, a power manager 1531, and / or a low-power display manager 1532. The framework 1140 may dynamically remove some existing components or may add new components.

[0155] In an embodiment, the window manager 1142 may manage GUI resources used on the screen. For example, the window manager 1142 may generate a window corresponding to content to be displayed on the display 210 using display information generated by at least one view.

[0156] In an embodiment, the power manager 1531 may manage the battery (e.g., Figure 1 The power manager 1531 can monitor the capacity, temperature, and / or power of the battery 189 of the electronic device 101 and can use the information related to the battery 189 to determine or provide power information required for the operation of the electronic device 101. The power manager 1531 can provide power corresponding to the operation mode or power consumption level of the display 210 of the electronic device 101 according to the control of the low power display application 1542.

[0158] In an embodiment, the low-power display manager 1532 may learn and / or analyze the physical properties of the display 210. The physical properties of the display 210 may have values ​​specified when the display 210 is manufactured. The low-power display manager 1532 may generate initial learning data by learning the physical characteristics of the display 210. The low-power display manager 1532 may update the learning data by continuously analyzing the physical properties that dynamically change according to the use of the display 210. The updated learning data may include the folding angle of the display 210, the size of the display 210, and the hardware physical property information of the display 210. The low-power display manager 1532 may predict the resulting value of the degree of degradation and / or aging of the display 210 by analyzing the updated learning data. The low-power display manager 1532 may generate a prediction model for the degree of degradation and / or aging of the display 210.

[0159] In an embodiment, the kernel 1120 may control, allocate, and / or retrieve system resources of the electronic device 101. The kernel 1120 may include a driver 1510 and an interface 1520.

[0160] In an embodiment, the driver 1510 may drive at least one hardware device of the electronic device 101. The driver 1510 may include a first driver 1511 and a second driver 1512. For example, the first driver 1511 may be referred to as a general display driver, and the second driver 1512 may be referred to as a display control driver.

[0161] In an embodiment, the first driver 1511 may store content data received through the low power display mode interface 1521 included in the interface 1520 in the memory 233 of the display device 160. The first driver 1511 may determine that the content data received through the low power display mode interface 1521 is content data for displaying the AOD screen during the low power display mode.

[0162] In an embodiment, the second driver 1512 may control the operation of the display 210 of the electronic device 101. The second driver 1512 may set the color, form, position and / or size of the AOD screen displayed on the display 210 according to the operation mode of the display 210 of the electronic device 101.

[0163] In an embodiment, the processor of the electronic device 101 (eg, Figure 1 The processor 120 and / or the framework 1140 may analyze the physical properties of the display 210. The processor 120 and / or the framework 1140 may dynamically perform degradation and / or aging testing of the display 210.

The low power display manager 1532 may control the brightness of the display 210 according to the power consumption level of the electronic device 101.

[0164] In an embodiment, the processor 120 and / or the framework 1140 may learn and / or analyze the physical properties of the display 210. The physical properties of the display 210 may be hardware physical properties of the display 210, such as brightness and / or size. The processor 120 and / or the framework 1140 may newly set a prediction model based on the dynamically changing physical properties of the display 210. The processor 120 and / or the framework 1140 may reorganize the AOD screen based on the set prediction model. The parameters of the display 210 used to set the prediction model may include brightness information of the display 210, the folding angle of the display 210, the size of the display 210, and hardware physical property information of the display 210.

[0165] Figure 16 16 is a view 1600 illustrating an example operation of generating a second screen 1622 by reorganizing a first screen 1611 of the display 210 of the electronic device 101 according to various embodiments.

[0166] In an embodiment, a processor (e.g., Figure 1 The processor 120 may display an AOD screen of a first screen 1611 on the display 210 when the display 210 is in the flat state 1610. When the display 210 changes from the flat state 1610 to the intermediate state 1620, the processor 120 may reorganize the first screen 1611. The intermediate state 1620 may be a state between the flat state 1610 and the folded state. In the intermediate state 1620, the folding angle of the display 210 may be greater than 0 degrees and less than 180 degrees. The processor 120 may generate a second screen 1622 by reorganizing the first screen 1611.

[0167] In an embodiment, when the second screen 1622 is generated by reorganizing the first screen 1611, the processor 120 may move the drawing area (eg, Figure 13 When the display 210 is in the intermediate state 1620, the moving area 1621 may be one of the two areas divided from each other by the folding axis B, and the processor 120 may move the second screen 1622 within the moving area 1621.

[0168] In an embodiment, the processor 120 may predict a result value of the degree of degradation and / or aging of the AOD screen displayed on the display 210. The processor 120 may predict a result value of the degree of degradation and / or aging caused by the AOD screen based on learning and / or analysis. Based on the predicted result value, the processor 120 may determine whether the degradation and / or aging test result of the display 210 is passed or failed.

[0169] In an embodiment, the processor 120 may determine whether the degree of degradation of the display 210 due to the second screen 1622 is less than or equal to a threshold. The processor 120 may calculate a result value by predicting whether the degree of degradation of the display 210 due to the second screen 1622 is less than or equal to the threshold. When the result value is less than or equal to the threshold, the processor 120 may determine that the degradation and / or aging test result has passed and may display the second screen 1622 on the screen. When the result value exceeds the threshold, the processor 120 may determine that the degradation and / or aging test result has failed and may perform the operation of changing the display properties again.

[0170] In an embodiment, when it is determined that the degradation and / or aging test result fails, the processor 120 may proceed to an additional correction state 1630. The processor 120 may generate a third screen 1632 by additionally changing the second screen 1622 in the additional correction state 1630. For example, when the degradation and / or aging test result fails, the processor 120 may generate the third screen 1632 by reducing the text size of the second screen 1622 and may display the third screen 1632 in the moving area 1631 of the display 210.

[0171] Figure 17 1700 is a view illustrating an example operation of generating a second screen by recombining a first screen of the display 210 of the electronic device 101 according to various embodiments.

[0172] In an embodiment, a processor (e.g., Figure 1 The processor 120 of the display 210 may display an AOD screen of a first screen 1711 on the display 210 when the display 210 is in the flat state 1710. When the display 210 begins to fold about the folding axis B and changes from the flat state 1710 to the first intermediate state 1720, the processor 120 may reorganize the first screen 1711. The processor 120 may generate a second screen 1721 by reorganizing the first screen 1711. When the display 210 continues to fold about the folding axis B and changes from the first intermediate state 1720 to the second intermediate state 1730, the processor 120 may reorganize the second screen 1721. The processor 120 may generate a third screen 1731 by reorganizing the second screen 1721.

[0173] In an embodiment, when the electronic device 101 is changed from the flat state 1710 to the intermediate state 1720 or 1730, the processor 120 may move the AOD screen so that the AOD screen does not overlap with the folding axis B of the display 210. When the display 210 is in the intermediate state 1720 or 1730, the processor 120 may display the AOD screen so that the AOD screen does not overlap with the folding axis B.

[0174] In an embodiment, the processor 120 may reorganize the AOD screen according to the folding state of the display 210. For example, the electronic device 101 may have various shape structures, such as a half-folding structure in which the display 210 is folded in half, and a Z-shaped flip folding structure in which the display 210 is folded into three parts and folded at approximately one-third of the display 210. The AOD screen may be displayed on the display 210 of the electronic device 101 having various shape structures. The processor 120 may reduce degradation and / or aging of the display 210 by dynamically changing the attribute information of the AOD screen according to the area where the AOD screen is displayed.

[0175] Figure 18 is a view 1800 illustrating an example operation of generating a second screen by reorganizing a first screen of a display 210 of an electronic device 101 according to various embodiments.

[0176] In an embodiment, when the display 210 is in the flat state 1810, the processor (e.g., the processor 120 of the electronic device 101) can display a first screen, which is an AOD screen including first content 1811 and second content 1812, on the display 210. When the display 210 starts to be folded about the folding axis B and changes from the flat state 1810 to an intermediate state 1820, the processor 120 can generate a second screen by reorganizing the first screen.

[0177] In an embodiment, when the display 210 is changed to the intermediate state 1820, the processor 120 can generate the second screen by dividing the first content 1811 and the second content 1812 from each other with respect to the folding axis B. For example, the processor 120 can display the first content 1811 in the form of a view intended to be viewed by the user on an area above the folding axis B, and can display the second content 1812 in the form of an icon that the user can input a touch on an area below the folding axis B.

[0178] In an embodiment, to prevent aging, the processor 120 can divide at least some content displayed by an application (e.g., the application 146 of the electronic device 101) according to a folding angle. For example, when a notification application is displayed as an AOD screen, the processor 120 can display a clock on an upper area of the display 210 with respect to the folding axis B, and can display an icon on a lower area of the display 210. To reduce deterioration and / or aging due to the first content 1811 and the second content 1812, the processor 120 can change display properties of the first content 1811 and the second content 1812. For example, the processor 120 can independently move the first content 1811 and the second content 1812 at each specified period. Figure 1

[0179] Figure 19 is a perspective view 1900 illustrating an example operation of generating a second screen by reorganizing a first screen of a display 210 of an electronic device 101 according to various embodiments.

[0180] In an embodiment, the processor (e.g., the processor 120 of the electronic device 101) can display a first screen, which is an AOD screen including first content 1911 and second content 1912, on the display 210. When the display 210 starts to be folded about the folding axis B and changes from the flat state 1910 to an intermediate state 1920, the processor 120 can generate a second screen by reorganizing the first screen. Figure 1 ​​The processor 120 can reorganize the first screen according to the arrangement direction and / or folding form of the electronic device 101. The processor 120 can generate the second screen according to the arrangement direction of the electronic device 101 and the viewing form of the display 210. When the electronic device 101 is folded about the folding axis B, the processor 120 can generate the second screen according to the first direction 1921 and the second direction 1922 facing the display 210.

[0181] In an embodiment, when the electronic device 101 is oriented in a landscape orientation, the processor 120 may display an AOD screen in which the position of the content is reorganized to reduce degradation and / or aging of the display 210. For example, when the display 210 is viewed as long in the landscape orientation and the folding axis B is formed in the portrait orientation, the processor 120 may display clock content in the first area 1911 on the left and may display notification content in the second area 1912 on the right. When the electronic device 101 is at least partially folded about the folding axis B, the processor 120 may set the position, size, font, and / or brightness of the content items according to the first direction 1921 and the second direction 1922 that the display 210 is facing.

[0182] Figure 20 is a stereoscopic diagram 2000 illustrating an example operation of generating a second screen by recombining a first screen of the display 210 of the electronic device 101 according to various embodiments.

[0183] In an embodiment, a processor (e.g., Figure 1 The processor 120 of the electronic device 101 may reorganize the first screen according to the direction of the electronic device 101 and / or the form of viewing the display 210. The processor 120 may generate the second screen according to the direction of the electronic device 101 and / or the form of viewing the display 210.

[0184] In an embodiment, when the electronic device 101 has a foldable shape that can be folded into three parts, the processor 120 can display the AOD screen on one-third of the viewing display 210. When the electronic device 101 is oriented in a landscape orientation as in the first situation 2010, the processor 120 can display the content of the AOD screen so that the user can read the content in the landscape orientation. When the electronic device 101 is oriented in a portrait orientation as in the second situation 2020, the processor 120 can rotate the content of the AOD screen by 90 degrees compared to when the electronic device 101 is oriented in a landscape orientation as in the first situation 2010.

[0185] Figure 21 is a stereoscopic diagram 2100 illustrating an example operation of generating a second screen by recombining a first screen of the display 210 of the electronic device 101 according to various embodiments.

[0186] In an embodiment, a processor (e.g., Figure 1 The processor 120 of the processor 120 can display the AOD screen 2110 on the electronic device 101 having a table foldable shape structure. For example, when the electronic device 101 is placed on the table in the form of a table clock (desk clock), the processor 120 can display the AOD screen 2110 including the clock in the form of the table clock, date and / or notification.

[0187] In an embodiment, the processor 120 may display the AOD screen 2110 to correspond to the form of the electronic device 101. For example, when the electronic device 101 has a slide-type structure, the processor 120 may display the AOD screen 2110 on the portion viewed by the user. In another example, when the cover is coupled to the electronic device 101, the processor 120 may display the AOD screen 2110 on the portion viewed by the user. When the form of the electronic device 101 is changed, the processor 120 may reorganize the AOD screen 2110 and may display a new AOD screen on the display 210.

[0188] Figure 22 is a diagram showing a method for displaying an electronic device (eg, Figure 1 The electronic device 101) has a display (eg, Figure 2 Flowchart 2200 of an example method for an AOD screen of a display 210).

[0189] In operation 2210, the processor (eg, Figure 1 The processor 120 of the electronic device 101 may turn on the AOD mode. In an inactive mode or sleep mode (e.g., low power mode), the processor 120 may turn on the AOD mode (e.g., low power display mode) of the display 210. The processor 120 may display an AOD screen on the display 210 by turning on the AOD mode. When the electronic device 101 receives user input, the processor 120 may switch the electronic device 101 from the AOD mode to the general mode.

[0190] In operation 2220, the processor 120 of the electronic device 101 according to an embodiment may randomize the starting point. The starting point may be a point at a designated location in the area where the AOD screen content is displayed when the AOD mode is turned on. For example, the starting point may be located at the upper left end of the area where the AOD screen content is displayed when the AOD mode is turned on. The processor 120 may randomly set the position of the starting point.

[0191] In operation 2230, the processor 120 of the electronic device 101 according to an embodiment may determine whether the AOD mode is turned off. When the AOD mode is turned off (operation 2230-yes), the processor 120 may proceed to operation 2235. When the AOD mode remains on (operation 2230-no), the processor 120 may proceed to operation 2240.

[0192] In operation 2235, the processor 120 of the electronic device 101 according to the embodiment may be switched to a general mode. In the general mode, the processor 120 may turn on the display 210 and may display an application (eg, Figure 1 When a designated period of time elapses in a state where there is no user input to the electronic device 101, the processor 120 may switch the electronic device 101 from the general mode to the AOD mode.

[0193] In operation 2240, the processor 120 of the electronic device 101 according to an embodiment may display an AOD screen. The processor 120 may display the AOD screen on the display 210. The processor 120 may determine the brightness of the AOD screen and may display the AOD screen at the determined illuminance.

[0194] In operation 2250, the processor 120 of the electronic device 101 according to an embodiment may determine whether a specified time interval has passed. The specified time interval may be a time interval for maintaining the degree of degradation and / or aging of the display 210 due to the AOD screen at a threshold value or less. For example, in the case where a clock is displayed on the AOD screen, the processor 120 may determine whether one minute has passed after the AOD screen is displayed. The processor 120 may maintain operation 2240 until the specified time interval has passed (operation 2250-no). When the specified time interval has passed, the processor 120 may enter operation 2260 (operation 2250-yes).

[0195] In operation 2260, the processor 120 of the electronic device 101 according to an embodiment may move in a diagonal direction. The processor 120 may move the AOD screen in the diagonal direction. For example, if a clock is displayed on the AOD screen, the processor 120 may move the AOD screen in the diagonal direction by a specified distance every minute. The specified distance may be substantially the same as the length and / or width of one pixel.

[0196] In operation 2270, the processor 120 of the electronic device 101 according to an embodiment may perform AOD conversion. The processor 120 may repeat operation 2240 by displaying the AOD screen at a position separated by a designated distance from the previous position in a diagonal direction.

[0197] Figure 23 is a diagram showing a method for displaying an electronic device (eg, Figure 1 The electronic device 101) has a display (eg, Figure 2 View 2300 of an example method of an AOD screen of a display 210).

[0198] In an embodiment, a processor (e.g., Figure 1 The processor 120 of the AOD screen may display the first content 2310 of the AOD screen on the display 210. The upper left end of the first content 2310 may be set as a random starting point.

[0199] In an embodiment, the processor 120 may perform a first movement to move the first content 2310 from the starting point based on a first rule for each specified first time interval when the first content 2310 is displayed. The first rule may be a rule for setting a small jump of the first content 2310. When the position represented by "0" is a random starting point, the processor 120 may start from "0" and move the first content 2310 to positions 1, 2, 3, 4, 5, 6, 7, 8, and 9 each time a specified time interval passes. For example, in the case where a clock is displayed on the AOD screen, the processor 120 may move the upper left end of the clock to positions 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9 for each minute that passes after the clock is displayed on the AOD screen.

[0200] In an embodiment, the processor 120 may perform a second movement to move the first content 2310 from the starting point based on a specified second rule at every specified second time interval. The second rule may be a rule for setting a large jump, by which the first content 2310 is reorganized into the second content 2320. The processor 120 may display the second content 2320 by reorganizing the first content 2310. For example, in the case where a clock is displayed on the AOD screen, the processor 120 may move the upper left end of the clock to a new position on the display 210 every ten minutes after the clock is displayed as the AOD screen. The processor 120 may allow the AOD screen to be displayed on the display 210 as a whole, thereby preventing degradation and / or aging of the display 210.

[0203] In operation 2420, the processor 120 of the electronic device 101 according to an embodiment may randomize the starting point. The starting point may be a point at a designated location in the area where the content of the AOD screen is displayed when the AOD mode is turned on. For example, the starting point may be located at the upper left end of the area where the content of the AOD screen is displayed when the AOD mode is turned on. The processor 120 may randomly set the position of the starting point.

[0204] In operation 2430, the processor 120 of the electronic device 101 according to an embodiment may determine whether the AOD mode is turned off. When the AOD mode is turned off (operation 2430-yes), the processor 120 may proceed to operation 2435. When the AOD mode remains on (operation 2430-no), the processor 120 may proceed to operation 2440.

[0205] In operation 2435, the processor 120 of the electronic device 101 according to an embodiment may switch to a general mode. In the general mode, the processor 120 may turn on the display 210 and may display an application (eg, Figure 1 When a designated period of time elapses in a state where there is no user input to the electronic device 101, the processor 120 may switch the electronic device 101 from the general mode to the AOD mode.

[0206] In operation 2440, the processor 120 of the electronic device 101 according to an embodiment may display an AOD screen. The processor 120 may display the AOD screen on the display 210. The processor 120 may determine the brightness of the AOD screen and may display the AOD screen at the determined illuminance.

[0207] In operation 2450, the processor 120 of the electronic device 101 according to an embodiment may determine whether a specified time interval has passed. The specified time interval may be a time interval for maintaining the degree of degradation and / or aging of the display 210 due to the AOD screen at a threshold value or less. For example, in the case where a clock is displayed on the AOD screen, the processor 120 may determine whether one minute has passed after the AOD screen is displayed. The processor 120 may maintain operation 2440 until the specified time interval has passed (operation 2450-no). When the specified time interval has passed, the processor 120 may enter operation 2460 (operation 2450-yes).

[0208] In operation 2460, the processor 120 of the electronic device 101 according to an embodiment may move in a random direction. The processor 120 may move the AOD screen in any direction. For example, if a clock is displayed on the AOD screen, the processor 120 may move the AOD screen a specified distance in any direction every minute. The specified distance may be up, down, left, right, and / or diagonal. The specified distance may be substantially the same as the length and / or width of a pixel.

[0209] In operation 2470, the processor 120 of the electronic device 101 according to an embodiment may perform AOD conversion. The processor 120 may repeat operation 2440 by displaying the AOD screen at a position spaced a designated distance from a previous position in any direction.

[0210] In an embodiment, the processor 120 may perform an AOD transition after a threshold time has passed. For example, if a clock is displayed on the AOD screen, the processor 120 may move the clock to an area on the display 210 that remains in the off state every hour after the clock is displayed on the AOD screen. The processor 120 may allow the AOD screen to be displayed on the display 210 as a whole, thereby preventing degradation and / or aging of the display 210.
