Description

Technology Field

[0001] The contents disclosed in this document relate to a method for reducing the degradation of a display of an electronic device and a technology for implementing a foldable electronic device to which the method is applied. Background Technology

[0002] An electronic device can display an image through a display disposed on the surface of a housing. Multiple pixels for displaying an image may be disposed on the display. Each of the multiple pixels may receive a data voltage and a light emission signal for displaying an image from a display driver IC (DDI).

[0003] Meanwhile, the electronic device may have an Always On Display (AOD) function that continuously displays information such as the time, date, battery level, and notifications on the display at low power when the screen is off. The AOD function allows the user to check information such as the time, date, battery level, and notifications without turning on the display screen.

[0004] Recently, foldable electronic devices capable of folding their displays have been emerging. Foldable electronic devices can display different screens on the display in the unfolded and folded states. Foldable electronic devices can switch to a low-power display mode in the folded state. Foldable electronic devices can display an AOD screen in the low-power display mode. The problem to be solved

[0005] Burn-in may occur if an electronic device continuously displays the same AOD screen on the display in low-power display mode. When burn-in occurs, afterimages may appear on the display. To prevent burn-in, the processor of the electronic device may be configured to move the AOD screen across the display by a specified interval at specified intervals. However, if a foldable electronic device is in a folded state in low-power display mode, it may not be easy to move the AOD screen across the display. Additionally, if content prone to causing burn-in is displayed on the AOD screen, it may not be easy to reduce burn-in.

[0006] The various embodiments disclosed in this document aim to provide a method for reducing burn-in while displaying various AOD screens for a specified period of time or longer in a foldable electronic device, and an electronic device to which the method is applied. means of solving the problem

[0007] A method for reducing degradation of a display of an electronic device according to an embodiment disclosed in this document may include: checking whether the display is in a low-power display mode that displays an Always On Display (AOD) screen; checking the content of a first screen displayed on the display when the display displays the AOD screen; detecting a folding angle of the display; reconstructing the first screen based on the folding angle to generate a second screen; and displaying the second screen on the display.

[0008] Additionally, a foldable electronic device according to an embodiment disclosed in this document, comprising a folded state, an unfolded state, and an intermediate state between the folded state and the unfolded state, comprises a display that displays a screen, a sensor module configured to acquire a folding angle of the display, and a processor operatively connected to the display and the sensor module, wherein the processor checks whether the display is in a low-power display mode that displays an Always On Display (AOD) screen, checks the content of a first screen displayed on the display when the display displays the AOD screen, detects the folding angle of the display using the sensor module, reconstructs the first screen based on the folding angle to generate a second screen, and is configured to display the second screen on the display. Effects of the invention

[0009] According to the embodiments disclosed in this document, a foldable electronic device can reconfigure the content of an AOD screen based on the folding angle of the display in a low-power display mode. By displaying a new screen as the folding angle of the display changes, burn-in of the display can be reduced.

[0010] In addition, according to the embodiments disclosed in this document, a foldable electronic device can check the content displayed on the display and reconstruct the screen based on the degree of burn-in. If the degree of burn-in is greater than a specified level, the burn-in of the display can be reduced by dynamically changing the displayed content.

[0011] In addition, various effects that can be identified directly or indirectly through this document may be provided. Brief explanation of the drawing

The magnetic body (342) may be used to detect the relative positional relationship between the first housing structure (310) and the second housing structure (320).

[0050] In one 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 composed of a combination of at least two of an acceleration sensor, an angular velocity sensor, and / or a geomagnetic sensor. The second motion sensor (350) can detect the posture and movement of the second housing structure (320). For example, the posture of the second housing structure (320) may be detected based on the acceleration sensor of the second motion sensor (350), and the movement of the second housing structure (320) may be detected 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 detected posture and movement 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). A magnetic sensor (352) may be placed in at least a portion of the second housing structure (320) adjacent to the hinge structure (360). The magnetic sensor (352) may detect magnetic force. The magnetic sensor (352) may detect the relative positional relationship between the first housing structure (310) and the second housing structure (320) based on the detected magnetic force. For example, the magnetic sensor (352) may detect sensing data related to the folding angle of the first housing structure (310) and the second housing structure (320) based on the detected magnetic force. The magnetic sensor (352) may transmit the detected sensing data to the processor (120).

[0051] In one embodiment, the first motion sensor (340), the second motion sensor (350), and / or the magnetic sensor (352) may include a 6-axis sensor and / or a digital Hall IC sensor. The 6-axis sensor and / or the digital Hall IC sensor may include hardware and software. The 6-axis sensor and / or the digital Hall IC sensor may produce 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 in 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 performing calculations on the raw data using a library consisting of source code.

[0053] FIG. 4 is a drawing (400) showing the folded state of an electronic device (e.g., the electronic device (101) of FIG. 1) according to one embodiment.

[0054] In one embodiment, one or more components may be disposed on or visually exposed on the rear surface of the electronic device (101). For example, one or more components or sensors, including a rear camera device (372) and / or a proximity sensor (374), may be visually exposed through the second surface (312) of the first housing structure (310). As another example, at least a portion of a sub-display (370) may be visually exposed through the second surface (312) of the first housing structure (310).

[0055] In one embodiment, the magnetic body of the first housing structure (310) (e.g., the magnetic body (342) of FIG. 3) and the magnetic sensor of the second housing structure (320) (e.g., the magnetic sensor (352) of FIG. 3) may face each other at least partially when the electronic device (101) is in a folded state. The magnetic sensor (352) can detect changes in magnetic force emitted from the magnetic body (342) due to changes in the unfolded state and / or the folded state.

[0056] In one embodiment, the angle and / or distance between the first housing structure (310) and the second housing structure (320) may change depending on whether the electronic device (101) is in an unfolded state (e.g., the state of FIG. 3), a folded state (e.g., the state of FIG. 4), or an intermediate state (e.g., the intermediate state of FIG. 3 and FIG. 4).

[0058] FIG. 5 is a flowchart (500) illustrating a method for reducing the degradation of a display (e.g., the display (210) of FIG. 2) of an electronic device (e.g., the electronic device (101) of FIG. 1) according to one embodiment.

[0059] A processor of an electronic device (101) according to one embodiment (e.g., processor (120) of FIG. 1) can check whether it is in a low-power display mode in operation 10. The processor (120) can check whether the display (210) is in a low-power display mode that displays an AOD (Always On Display) screen.

[0060] In one embodiment, the AOD screen may be a screen that continuously displays information such as time, date, battery level, and notifications on the display (210) at low power while the screen of the display (210) is turned off. While the AOD screen is displayed, the user of the electronic device (101) can check information such as time, date, battery level, and notifications without turning on the screen of the display (210).

[0061] In one embodiment, the processor (120) may proceed to operation 20 when the display (210) is in a low-power display mode (operation 10 - Yes). The processor (120) may display a screen on the display (210) without proceeding to operation 20 when the display (210) is in a normal mode with the screen turned on (operation 20 - No).

[0062] In operation 20, the processor (120) of the electronic device (101) according to one embodiment can check the content of the first screen displayed by the display (210). For example, when the display (210) displays an AOD screen, the processor (120) can check the type and / or characteristics of the content displayed on the AOD screen.

[0063] A processor (120) of an electronic device (101) according to one embodiment can detect the folding angle of a display (210) in operation 30. The processor (120) can receive first motion data and second motion data from a first motion sensor (e.g., the first motion sensor (340) of FIG. 3) and a second motion sensor (e.g., the second motion sensor (350) of FIG. 3). The processor (120) can receive sensing data related to the folding angle of a first housing structure (310) and a second housing structure (320) from a magnetic sensor (e.g., the magnetic sensor (352) of FIG. 3). The processor (120) can detect the folding angle of the display (210) based on the received first motion data, second motion data, and / or sensing data. The processor (120) can detect the folding angle of the display (210) at designated intervals to determine whether the folding angle of the display (210) has changed.

[0064] In one embodiment, the processor (120) of the electronic device (101) may generate a second screen by reconstructing a first screen based on a folding angle in operation 40. The processor (120) may generate a second screen that causes less degradation and / or burn-in of the display (210) than the first screen by reconstructing the content of the first screen to reduce degradation and / or burn-in of the display (210).

[0065] In one 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, shift the graphic content of the AOD screen by a specified interval, or split the graphic content and text of the AOD screen from each other.

[0066] In one embodiment, the processor (120) can detect the operating characteristics of the display (210) that change according to the folding angle of the display (210). For example, the processor (120) can detect the ppi (pixels per inch), dpi (dots per inch), brightness, resolution, and / or power consumption of the display (210) that change according to the folding angle of the display (210). The processor (120) can generate a second screen by changing the display characteristics of the display (210) according to the operating characteristics of the display (210).

[0067] A processor (120) of an electronic device (101) according to one embodiment may display a second screen on a display (210) in operation 50. When displaying an AOD screen, the processor (120) may reduce the degradation and / or burn-in of the display (210) by displaying a second screen that includes content having substantially the same type and / or content as the first screen and has a low degree of causing degradation and / or burn-in of the display (210). The second screen may be a screen that changes 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 that changes the average brightness and / or maximum brightness to below a specified threshold brightness value. The second screen may be a screen that changes the size of the content constituting the AOD screen to below a specified threshold value.

[0068] In one embodiment, the processor (120) calculates the brightness, color, position, arrangement relationship, and / or size of the content of the first screen, and if it is determined that the degree to which the first screen causes degradation and / or burn-in is greater than a specified degree, it may display a second screen that has changed the first screen. For example, the processor (120) may change the font of the text included in the AOD screen to a thinner font, shift the spacing between the graphic contents of the AOD screen by a specified spacing, or split and display the graphic contents and text of the AOD screen separately.

[0070] FIG. 6 is a drawing (600) showing a low-power display mode of a display (210) of an electronic device (101) according to one embodiment.

[0071] In one embodiment, the processor of the electronic device (101) (e.g., the processor (120) of FIG. 1) may support an active state or wake-up state, which is a state in which the user can primarily use the functions of the electronic device (101), and an inactive state or sleep state, which is a state waiting for the user to use.

[0072] In one embodiment, the processor (120) can control a plurality of hardware modules and / or software modules included in the electronic device (101) to operate in a normal mode in an active state or wake-up state. The processor (120) can control a power management module (e.g., power management module (188) of FIG. 1) so that the plurality of hardware modules and / or software modules receive rated power from a battery (e.g., battery (189) of FIG. 1) in a normal mode. In a normal mode, the plurality of hardware modules and / or software modules can perform functions without limitation. For example, in an active state or wake-up state, the processor (120) can turn on the display (210) by receiving rated power to display the execution screen of an application (e.g., application (146) of FIG. 1) or receive user touch input while maintaining a specified sensitivity.

[0073] In one embodiment, the processor (120) can control a plurality of hardware modules and / or software modules included in the electronic device (101) to operate in a low-power mode while in a disabled state or in a sleep state. The processor (120) can control the power management module (188) so that the plurality of hardware modules and / or software modules receive minimum power from the battery (189) while in a low-power mode. In a low-power mode, the plurality of hardware modules and / or software modules may be disabled or perform only designated limited functions. The processor (120) can control the plurality of hardware modules and / or software modules so that they perform only limited functions while in a disabled state or in a sleep state. In a deactivated or sleep state, information processing or computational operations of multiple hardware modules and / or software modules may be suppressed, thereby reducing the power consumption of multiple hardware modules and / or software modules and increasing the usage time of the battery (189). According to one embodiment, the processor (120) may control a display driving circuit (e.g., the display driver IC (230) of FIG. 2) so that the display (210) operates in a deactivated or sleep state (or operates in a low-power display mode) in a low-power mode. For example, the processor (120) may control the display driver IC (230) so that the display (210) outputs content such as text and / or images indicating a digital clock, date, and / or battery status to a first area (611) of the display (210) in a deactivated or sleep state. As another example, the processor (120) can control the display driver IC (230) so that the display (210) outputs various types of GUI (Graphic User Interface) objects, such as icons, to the second area (612) of the display (210).Text, images, and / or GUI objects included in the first area (611) and the second area (612) can constitute the AOD screen.

[0074] In one embodiment, text, images, and / or GUI objects contained in a first area (611) and a second area (612) of a display (210) of an electronic device (101) operating in an inactive or sleep state may be displayed in a designated first color (e.g., white). Pixels constituting the text, images, and / or GUI objects contained in the first area (611) and the second area (612) may emit light in the first color. A background area other than the first area (611) and the second area (612) may be set to a second color (e.g., black). Pixels placed in the background area may be set to have the second color. For example, if the display (210) includes an OLED (Organic Light Emitting Diode) panel, pixels placed in the background area may be turned off.

[0075] According to one embodiment, text, images, and / or GUI objects 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, degradation and / or burn-in of the pixels displaying text, images, and / or GUI objects in the first area (611) and the second area (612) can be reduced.

[0076] According to one embodiment, the display (210) can detect a user's touch input to GUI objects included in the second area (612) while consuming minimal power while operating in an inactive or sleep state (or, operating in a low-power display mode). The processor (120) can switch the display (210) to an active state or a wake-up state when a user's touch input to GUI objects included in the second area (612) is detected.

[0077] In one 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 in a first area (611). For example, the first object may be content such as a digital clock, date, and / or text and / or an image representing battery status displayed in the first area (611). The second object may be displayed in a second area (612). For example, the second object may be various types of GUI objects such as icons.

[0078] In one embodiment, the processor (120) may be configured to check whether an event for switching to a sleep state of the processor (120) occurs. The processor (120) may check whether an event for switching to a low-power display mode occurs. For example, the electronic device (101) may execute the low-power display mode as the processor (120) switches to a sleep state when the low-power display mode is activated. Accordingly, the operation of checking whether the low-power display mode of operation 10 of FIG. 5 is a low-power display mode may include the operation of the processor (120) of the electronic device (101) checking whether an event for switching to a sleep state of the processor (120) occurs.

[0080] FIG. 7a is a drawing (700) showing the first content (710, 720, 730) of the first screen displayed on the display (210) of the low-power display mode according to one embodiment.

[0081] In one embodiment, a processor (e.g., processor (120) of FIG. 1) of an electronic device (e.g., electronic device (101) of FIG. 1) may be configured to check a list of applications (e.g., application (146) of FIG. 1) that are executed. The processor (120) may check the type and / or form of the first content (710, 720, 730) displayed on the display (210) according to the execution of the application (146). The processor (120) may check the list of applications (146) when an event for switching to a low-power display mode occurs. The operation of checking the content of the first screen displayed on the display (210) of operation 20 of FIG. 5 may include the operation of checking the list of applications executed by the processor (120) of the electronic device (101).

[0082] In one embodiment, the processor (120) may display an AOD screen containing first content (710, 720, 730) when the orientation of the display (210) of the electronic device (101) is oriented toward a vertically elongated orientation. The first content (710, 720, 730) may be content displayed to correspond to viewing in a vertically elongated orientation. When the orientation of the display (210) of the electronic device (101) is oriented toward a vertically elongated orientation, the processor (120) may determine that the electronic device (101) is positioned vertically elongated so that the user views the display (210) in a vertically elongated state.

[0083] In one embodiment, the type and / or form of the first content (710, 720, 730) of the AOD screen displayed on the display (210) may vary. For example, the first content (710, 720, 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), as shown in FIG. 7a. For example, the at least one notification icon (730) may include a notification icon for the number of missed calls and / or a notification icon for the number of received messages. As 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) can receive information regarding the type, content, and / or form of the first content (710, 720, 730) of the AOD screen displayed on the display (210) from a display driving circuit (e.g., the display driver IC (230) of FIG. 2).

[0085] FIG. 7b is a drawing showing the second content (760, 770, 780, 790) of the first screen displayed on the display (210) of the low-power display mode according to one embodiment.

[0086] In one embodiment, the processor (120) may display an AOD screen containing second content (760, 770, 780, 790) when the direction of the display (210) of the electronic device (101) is oriented toward a horizontally elongated angle. The second content (760, 770, 780, 790) may be content displayed to correspond to viewing in a horizontally elongated direction. When the direction of the display (210) of the electronic device (101) is oriented toward a horizontally elongated angle, the processor (120) may determine that the electronic device (101) is positioned horizontally elongated so that the user views the display (210) in a horizontally elongated state.

[0087] In one embodiment, the type and / or form of the second content (760, 770, 780, 790) of the AOD screen displayed on the display (210) may vary. For example, the second content (760, 770, 780, 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), as shown in FIG. 7b. As 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 regarding the type, content, and / or form of the second content (760, 770, 780, 790) of the AOD screen displayed on the display (210) from the display driver IC (230).

[0089] FIG. 8 is a block diagram (800) showing components for detecting the folding angle of a display (210) of an electronic device (e.g., the electronic device (101) of FIG. 1) according to one embodiment. The electronic device (101) according to one embodiment may include a sensor module (176), a processor (120), a DDI (Display Driver Integrated circuit) (230) (e.g., the display driver IC (230) of FIG. 2), a display (210), and a memory (130).

[0090] In one embodiment, the sensor module (176) can detect sensing data related to the folding angle of the display (210), which is the angle formed by the two sides of the display (210) at the folded portion when the display (210) is folded. For example, the sensor module (176) can acquire sensing data from at least one of a motion sensor or a magnetic sensor. The sensor module (176) can transmit the acquired sensing data to the processor (120). The processor (120) can calculate the folding angle of the display (210) based on the sensing data. The processor (120) can periodically acquire sensing data from at least one of the motion sensor or magnetic sensor included in the sensor module (176). The processor (120) can periodically check whether the folding angle of the display (210) changes based on the sensing data. The operation of detecting the folding angle of the display (210) of operation 30 of FIG. 5 may include the operation of the processor (120) periodically acquiring sensing data using a sensor module (176) including a motion sensor and / or a magnetic sensor.

[0091] In one embodiment, the processor (120) can calculate a change in the shape of the content displayed on the display (210) according to a change in the folding angle based on a change in sensing data. The processor (120) can calculate how the shape of the content displayed on the display (210) changes to the user when the folding angle changes. The operation of detecting the folding angle of the display (210) of operation 30 of FIG. 5 may include the operation of the processor (120) calculating a change in the shape of the content displayed on the display (210) in response to a change in the folding angle.

[0092] In one embodiment, the processor (120) can detect whether the electronic device (101) is in an unfolded state, a folded state, and / or an intermediate state based on sensing data. The processor (120) can detect whether the electronic device (101) changes from one state of the unfolded state, a folded state, and / or intermediate state to another state. When a change in the state of the electronic device (101) is identified, the processor (120) can transmit information of a display area corresponding to the changed state of the electronic device (101) to an application (e.g., the application (146) of FIG. 1).

[0093] In one embodiment, when a change in the state of an electronic device (101) is identified based on sensing data, the processor (120) may transmit information regarding the display area of ​​the display (210) corresponding to the changed state of the electronic device (101) to the processor (120) for an application (146) that has established continuity among the applications (146) currently running. The processor (120) may compare the first display area information of the display (210) according to the state of the electronic device (101) before the change and the second display area information of the display (210) according to the state of the electronic device (101) after the change. For example, when the state of the electronic device (101) changes, the resolution of the content displayed on the display (210) may change. The processor (120) may store information regarding the resolution of the content displayed on the display (210) in the first display area information and the second display area information in order to indicate the change in resolution based on sensing data, and store this information in the memory (130).

[0095] FIG. 9 is a block diagram (900) showing components for detecting the folding angle of a display (e.g., display (210) of FIG. 2) of an electronic device (e.g., electronic device (101) of FIG. 1) according to one embodiment. The electronic device (101) according to one embodiment may include an angle sensor (911), a distance sensor (912), a gyroscope sensor (913), an input framework (920), and a folding angle change event control unit (930).

[0096] In one embodiment, the angle sensor (911), distance sensor (912), and gyroscope sensor (913) can acquire sensing data related to the folding angle of the electronic device (101), the distance between the first housing structure (e.g., the first housing structure (310) of FIG. 3) and the second housing structure (e.g., the second housing structure (320) of FIG. 3), and the direction in which the display (e.g., the display (210) of FIG. 2) is facing. The angle sensor (911), distance sensor (912), and gyroscope sensor (913) can be connected to the input framework (920) through a sensor driver (not shown). The sensor driver (not shown) may be a software module for controlling the angle sensor (911), distance sensor (912), and gyroscope sensor (913). The angle sensor (911), distance sensor (912), and gyroscope sensor (913) can transmit sensing data to the input framework (920).

[0097] In one embodiment, the input framework (920) may receive sensing data from an angle sensor (911), a distance sensor (912), and a gyroscope sensor (913) to measure the unfolded state and / or folded state of the electronic device (101). The input framework (920) may determine the unfolded 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 control unit (930). For example, the input framework (920) may transmit a first signal indicating that the electronic device (101) is in an unfolded state to the folding angle change event control unit (930). As another example, the input framework (920) may transmit a second signal indicating that the electronic device (101) is in a folded state to the folding angle change event control unit (930).

[0098] In one embodiment, the folding angle change event control unit (930) may receive an event related to a change in the unfolded state and / or folded state of the transmitted electronic device (10). The folding angle change event control unit (930) may control the turn-on and / or turn-off of the display (210) and the sub-display (e.g., the sub-display (370) of FIG. 4).

[0099] In one embodiment, the folding angle change event control unit (930) can perform activation and / or deactivation of the display (210) and activation and / or deactivation of the sub-display (370) based on the state of the currently running application (e.g., application (146) of FIG. 1), a policy stored in memory (e.g., memory (130) of FIG. 1) in response to a state change of the electronic device (101), and / or a state allowing activation or deactivation of the display (210).

[0101] FIG. 10 is a drawing (1000) showing a change in the folding angle of a display (e.g., display (210) of FIG. 2) of an electronic device (e.g., electronic device (101) of FIG. 1) according to one embodiment.

[0102] In one embodiment, the first housing structure (310) and the second housing structure (320) of the electronic device (101) can be folded to face each other using a hinge structure (360). With the hinge structure (360) as a vertex, the first housing structure (310) and the second housing structure (320) can have various folding angles such as a first folding angle (θ1), a second folding angle (θ2), a third folding angle (θ3), and a fourth folding angle (θ4). The first folding angle (θ1), the second folding angle (θ2), the third folding angle (θ3), and the fourth folding angle (θ4) can be angles from 0 degrees to 180 degrees. For example, the first folding angle (θ1) may be approximately 45 degrees, the second folding angle (θ2) may be approximately 75 degrees, the third folding angle (θ3) may be approximately 120 degrees, and the fourth folding angle (θ4) may be approximately 150 degrees. The first folding angle (θ1), the second folding angle (θ2), the third folding angle (θ3), and the fourth folding angle (θ4) may indicate an intermediate state of the electronic device (101). When the folding angle is 0 degrees, the electronic device (101) may be in a folded state, and when the folding angle is 180 degrees, the electronic device (101) may be in an unfolded state. As the first housing structure (310) and the second housing structure (320) of the electronic device (101) are unfolded and folded, the display (210) may be unfolded and folded. 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).

[0103] In one embodiment, the electronic device (101) can change the AOD screen displayed on the display (210) as the folding angle of the display (210) changes. In one embodiment, when changing the AOD screen of the display (210), the electronic device (101) can change it to an AOD screen that causes less degradation and / or burn-in on the display (210) in order to reduce degradation and / or burn-in of the display (210).

[0104] In one embodiment, the display (210) of the electronic device (101) may be a foldable form-factor structure connected to the inside and displayed to the outside. The display (210) of the foldable form-factor structure may display an AOD screen through a portion excluding the parts that are folded facing each other. For example, the display (210) of the foldable form-factor structure may display an AOD screen through an area exposed to the outside when the electronic device (101) is in a folded state. A processor (e.g., processor (120) of FIG. 1) may change the display characteristics of the display (210) when the folding angle of the display (210) changes in order to reduce the phenomenon of degradation and / or burn-in occurring in the display (210) that displays the AOD screen for a long time.

[0106] FIG. 11 is a block diagram (1100) showing components that reduce the degradation of a display (210) of an electronic device (e.g., the electronic device (101) of FIG. 1) according to one embodiment. The electronic device (101) according to one embodiment may include hardware (1110), a kernel (1120), a library (1130), a framework (1140), and an application (146).

[0107] In one embodiment, the hardware (1110) may include a sensor module (e.g., the sensor module (176) of FIG. 1) and a display (210). In one embodiment, the electronic device (101) may identify a change in the state of the electronic device (101) based on the sensor module (176). In one embodiment, the electronic device (101) may display an AOD screen with reconfigured content on the display (210).

[0108] In one embodiment, the kernel (1120) may include a state management module (1121) and a DDI (230). In one embodiment, the state management module (1121) may identify a change in the state of the electronic device (101) based on the sensor module (176). In one embodiment, the electronic device (101) may display a screen on the display (210) using the DDI (230).

[0109] In one embodiment, the state management module (1121) can activate at least a portion of the display area of ​​the display (210) when a change in the state of the electronic device (101) is identified through the sensor module (176). For example, the state management module (1121) can activate at least a portion of the display area of ​​the display (210) by transmitting an activation signal to the DDI (230).

[0110] In one 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, the state management module (1121) may activate a display area of ​​the display (210) corresponding to the unfolded state (e.g., a first display area) when the state of the electronic device (101) changes from a folded state to an unfolded state or when the size of the folding angle increases. As another example, the state management module (1121) may activate a display area of ​​the display (210) corresponding to the folded state (e.g., a second display area) when the state of the electronic device (101) changes from an unfolded state to a folded state or when the size of the folding angle decreases. The state management module (1121) may manage the folding state of the display (210), such as in-folding and / or out-folding.

[0111] In one embodiment, the state management module (1121) can calculate the folding angle of the display (210) based on sensing data received from the sensor module (176). The state management module (1121) can transmit the calculated folding angle of the display (210) to the window manager (1142) and / or the burn-in prevention management module (1143). In a normal operating state, the state management module (1121) can transmit the folding angle of the display (210) to the burn-in prevention module (1143) via the window manager (1142). The state management module (1121) can transmit the folding angle of the display (210) directly to the burn-in prevention module (1143) without passing through the window manager (1142) to minimize current consumption or to adjust the AOD in a sleep state.

[0112] In one embodiment, the library (1130) may include a layer compositing unit (1131). The layer compositing unit (1131) may composite a plurality of layers containing content to be displayed on a display (210). For example, the layer compositing unit (1131) may be a Surface Flinger. The layer compositing unit (1131) may provide data representing the composited plurality of layers to the DDI (230).

[0113] In one embodiment, the framework (1140) may include a drawing manager (1141), a window manager (1142), and a burn-in prevention management module (1143). The burn-in prevention management module (1143) may be included in a processor (e.g., the processor (120) of FIG. 1). The burn-in prevention management module (1143) may be included in the window manager (1142).

[0114] In one embodiment, the drawing manager (1141) can 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. The drawing manager (1141) can draw a screen by the application (146) based on the resolution of the second display area of ​​the display (210).

[0115] In one embodiment, when a change in the state of the electronic device (101) is identified through the state management module (1121), the window manager (1142) can transmit information of the display area corresponding to the changed state of the electronic device (101) to the burn-in prevention management module (1143). For example, when a change in the folding state of the electronic device (101) is identified, the window manager (1142) can transmit information of the display area corresponding to the changed folding state of the electronic device (101) to the burn-in prevention management module (1143).

[0116] In one embodiment, the burn-in prevention 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). The burn-in prevention management module (1143) may receive information that the folding state of the electronic device (101) has changed from the window manager (1142) in a normal operating state. The burn-in prevention management module (1143) may receive information that the folding state of the electronic device (101) has changed from the state management module (1121) in order to minimize current consumption or to adjust the AOD in a sleep state. The burn-in prevention management module (1143) may reconfigure the content of the AOD screen based on the folding angle of the electronic device (101) to reduce the degree of degradation and / or burn-in of the display (210). For example, the burn-in prevention management module (1143) can configure an AOD screen associated with a running first application (1151) to display an AOD screen based on the folding angle of the display (210). The burn-in prevention management module (1143) can notify the running first application (1151) of a change in the folding angle of the display (210) to reconfigure the AOD screen. The burn-in prevention management module (1143) can perform a change in the display characteristics of the display (210) based on the folding angle, an analysis of the physical properties of the display (210), and a determination regarding whether the degree of burn-in of the display (210) is below a threshold value.

[0117] In one embodiment, the application (146) may include a first application (1151) that is running. The first application (1151) may draw at least one layer based on 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 running in the first application (1151). For example, the first application (1151) may draw at least one layer corresponding to the resolution of the display area of ​​the display (210) using a drawing manager (1141), such as a view. Accordingly, the first application (1151) may draw an AOD screen.

[0119] FIG. 12 is a flowchart (1200) illustrating a method for generating a second screen based on the folding angle of a display (e.g., display (210) of FIG. 2) of an electronic device (e.g., electronic device (101) of FIG. 1) according to one embodiment.

[0120] A processor (e.g., processor (120) of FIG. 1) and / or a burn-in prevention management module (e.g., burn-in prevention management module (1143) of FIG. 11) of an electronic device (101) according to one embodiment may analyze the display characteristics of the display (210) based on the folding angle in operation 1210. The processor (120) and / or the burn-in prevention management module (1143) may analyze the display characteristics or display attributes 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 the operation of reconstructing the first screen of operation 40 of FIG. 5 to generate a second screen.

[0121] In one embodiment, the processor (120) and / or burn-in prevention management module (1143) of the electronic device (101) can analyze the physical properties of the display (210) in operation 1220. The processor (120) and / or burn-in prevention management module (1143) can analyze and / or predict physical properties, such as hardware physical property information of the display (210), for the deterioration and / or burn-in suppression of the display (210). Operation 1220 may be included in the operation of reconstructing the first screen of operation 40 of FIG. 5 to generate a second screen.

[0122] In one embodiment, the processor (120) and / or burn-in prevention management module (1143) of the electronic device (101) can determine whether the degree of burn-in of the display (210) is below a threshold value in operation 1230. The processor (120) and / or burn-in prevention management module (1143) can predict the degree of burn-in caused by the AOD screen displayed on the display (210) according to the display attributes of the AOD screen. The processor (120) and / or burn-in prevention management module (1143) can predict a burn-in pass or a burn-in fail according to the predicted degree of burn-in. A burn-in pass may be a test result in which the degree of burn-in predicted to occur by the AOD screen displayed on the display (210) is below a specified threshold value. A burn-in fail may be a test result in which the degree of burn-in predicted to occur by the AOD screen displayed on the display (210) exceeds a specified threshold value. The processor (120) and / or the burn-in prevention management module (1143) may determine that the burn-in level of the display (210) is below a threshold value (operation 1230 - YES) and proceed to operation 1240. The processor (120) and / or the burn-in prevention management module (1143) may determine that the burn-in level of the display (210) is above a threshold value (operation 1230 - NO) and return to operation 1210. Operation 1230 may be included in the operation of reconstructing the first screen of operation 40 of FIG. 5 to generate a second screen.

[0123] In one embodiment, the processor (120) and / or burn-in prevention management module (1143) of the electronic device (101) may create a second screen by changing display characteristics in operation 1240. If the processor (120) and / or burn-in prevention management module (1143) determines that a second screen is created in which the degree of burn-in occurs below a threshold value, the processor may create a second screen by changing the display characteristics to correspond to the burn-in pass test result. For example, the processor (120) may create a second screen by reducing the size of the content displayed on the first screen by a certain ratio. As another example, the processor (120) may create a second screen in which at least some of the multiple contents displayed on the first screen, such as a clock, battery, date, and notifications, are hidden. As yet another example, the processor (120) may create a second screen by dividing and rearranging the content displayed on the first screen. Operation 1240 may be included in the operation of creating a second screen by reconstructing the first screen of operation 40 of FIG. 5.

[0125] FIG. 13 is a drawing (1300) showing a drawing area (1310) and a moving area (1320) of a display (210) of an electronic device (e.g., the electronic device (101) of FIG. 1) according to one embodiment.

[0126] In one embodiment, the drawing area (1310) may be an area that displays content included in the AOD screen when the display (210) displays the AOD screen. The drawing area (1310) may have a first length (D1) in a first direction (e.g., horizontal direction or X-axis direction). The first length (D1) may be approximately 250 dp (dot point) or more and approximately 300 dp or less. The drawing area (1310) may have a second length (D2) in a second direction (e.g., vertical direction or Y-axis direction). The second length (D2) may be approximately 300 dp or more and approximately 350 dp or less.

[0127] In one embodiment, the movement area (1320) may be an area where the content included in the AOD screen can be moved when the display (210) displays the AOD screen. The movement area (1320) may have a third length (D3) in a first direction. The third length (D3) may be about 300dp or more and about 320dp or less. The movement area (1320) may have a fourth length (D4) in a second direction. The fourth length (D4) may be about 400dp or more and about 500dp or less.

[0128] In one embodiment, the movement area (1320) may include a drawing area (1310). The area of ​​the movement area (1320) may be larger than the area of ​​the drawing area (1310). The movement area (1320) may be longer than the drawing area (1310) by a fifth length (D5) in a second direction. The movement area (1320) may be longer than the drawing area (1310) by a sixth length (D6) in a first direction.

[0129] In one embodiment, the moving area (1320) may be set as a part of the display (210). The moving area (1320) may be an area inward by a seventh length (D7) in a first direction from the edge of the display (210). The seventh length (D7) may be about 20dp or more and about 30dp or less.

[0130] In one embodiment, the drawing area (1310) may be moved periodically or non-periodically by a specified distance within the moving area (1320). By moving the drawing area (1310) within the moving area (1320), degradation and / or burn-in of the display (210) may be reduced.

[0131] In one embodiment, the processor of the electronic device (101) (e.g., the processor (120) of FIG. 1) may be configured to change the display characteristics of the display (210) based on the folding angle. For example, the processor (120) may variably set the drawing area (1310) and the movement area (1320) according to the folding angle and the structure of the display (210) in the form of a foldable form factor when the display (210) displays an AOD screen. The processor (120) may change the display characteristics of the AOD screen according to the variably changing characteristics of the display (210) to reduce degradation and / or burn-in of the display (210). The display characteristics of the AOD screen may include the brightness of the content constituting the AOD screen, the font of the text constituting the content constituting the AOD screen, the size of the content constituting the AOD screen, and the location information of the content constituting the AOD screen. For example, when the text font of the content constituting the first screen, the AOD screen, is the same as a Gothic font or a bold font, changing the text font of the content constituting the AOD screen to a fine font to display the second screen can reduce the degradation and / or burn-in of the display (210) compared to when text such as a Gothic font or a bold font is displayed.

[0133] FIG. 14 is a drawing (1400) showing a half-fold mode (1410, 1420) of an electronic device (101) according to one embodiment.

[0134] In one embodiment, the electronic device (101) can be folded in half along the folding axis (B) in a half-fold mode (1410, 1420). The half-fold mode (1410, 1420) may be an in-folded structure in which the display (210) is folded in half. In the half-fold mode (1410, 1420), the display (210) can be folded so that the first region (1411) and the second region (1412) face each other.

[0135] In one embodiment, the electronic device (101) may display an AOD screen (1421) in a first area (1411). The processor of the electronic device (101) (e.g., the processor (120) of FIG. 1) may reconfigure the AOD screen (1421) based on the folding angle to reduce degradation and / or burn-in of the display (210). The processor (120) may reconfigure a screen associated with an application (146) running the AOD screen (1421) based on the folding angle of the display (210) and display it on the display (210). For example, 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) in half-fold mode (1410, 1420).

[0137] FIG. 15 is a block diagram (1500) showing components for controlling a display (e.g., display (210) of FIG. 2) of an electronic device (e.g., electronic device (101) of FIG. 1) according to one embodiment in a low-power display mode.

The processor (120) and / or framework (1140) may establish a new prediction model based on the dynamically changing physical properties of the display (210). The processor (120) and / or framework (1140) may reconfigure the AOD screen according to the established prediction model. The parameters for establishing the prediction model of the display (210) may include brightness information of the display (210), folding angle of the display (210), size of the display (210), and hardware physical property information of the display (210).

[0153] FIG. 16 is a drawing (1600) showing the operation of reconstructing a first screen (1611) of a display (210) of an electronic device (101) according to one embodiment to create a second screen (1622).

[0154] In one embodiment, a processor (e.g., processor (120) of FIG. 1) may display an AOD screen of a first screen (1611) on the display (210) when the display (210) is in an unfolded state (1610). The processor (120) may reconfigure the first screen (1611) when the display (210) changes from an unfolded state (1610) to an intermediate state (1620). The intermediate state (1620) may be an intermediate state between the unfolded state (1610) and the folded state. In the intermediate state (1620), the folding angle of the display (210) may be an angle greater than 0 degrees and less than 180 degrees. The processor (120) may reconfigure the first screen (1611) to generate a second screen (1622).

[0155] In one embodiment, when the processor (120) reconfigures the first screen (1611) to create a second screen (1622), it may move a drawing area (e.g., the drawing area (1310) of FIG. 13) that displays the content of the AOD screen within a moving area (1621) which is an area where the content can be displayed. When the display (210) is in an intermediate state (1620), the moving area (1621) may be either of two areas divided by a folding axis (B). The processor (120) may move the second screen (1622) within the moving area (1621).

[0156] In one embodiment, the processor (120) can predict a result value regarding the degree of degradation and / or burn-in caused by an AOD screen displayed on the display (210). The processor (120) can predict a result value regarding the degree of degradation and / or burn-in caused by an AOD screen based on learning and / or analysis. Based on the predicted result value, the processor (120) can determine the degradation and / or burn-in test result of the display (210) as pass or fail.

[0157] In one embodiment, the processor (120) can check whether the degree of burn-in of the display (210) by the second screen (1622) is below a threshold value. The processor (120) can calculate a result value by predicting whether the degree of burn-in of the display (210) by the second screen (1622) is below a threshold value. If the result value is below the threshold value, the processor (120) can determine the degradation and / or burn-in test result as a pass and display the second screen (1622) on the screen. If the result value exceeds the threshold value, the processor (120) can determine the degradation and / or burn-in test result as a failure and perform the operation of changing the display attribute again.

[0158] In one embodiment, the processor (120) may transition to an additional correction state (1630) if it determines that the degradation and / or burn-in test result is a failure. In the additional correction state (1630), the processor (120) may further modify the second screen (1622) to generate a third screen (1632). For example, if the degradation and / or burn-in test result is a failure, the processor (120) may generate a third screen (1632) with reduced text size of the second screen (1622) and display it within the moving area (1631) of the display (210).

[0160] FIG. 17 is a drawing (1700) showing the operation of reconstructing a first screen of a display (210) of an electronic device (101) according to another embodiment to generate a second screen.

[0161] In one embodiment, a processor (e.g., processor (120) of FIG. 1) can display an AOD screen of a first screen (1711) on the display (210) when the display (210) is in an unfolded state (1710). The processor (120) can reconstruct the first screen (1711) when the display (210) begins to fold along the folding axis (B) and changes from the unfolded state (1710) to a first intermediate state (1720). The processor (120) can reconstruct the first screen (1711) to create a second screen (1721). The processor (120) can reconstruct the second screen (1721) when the display (210) continues to fold along the folding axis (B) and changes from the first intermediate state (1720) to a second intermediate state (1730). The processor (120) can reconfigure the second screen (1721) to generate the third screen (1731).

[0162] In one embodiment, the processor (120) can move the AOD screen so as not to overlap with the folding axis (B) of the display (210) when changing the electronic device (101) from an unfolded state (1710) to an intermediate state (1720, 1730). The processor (120) can display the AOD screen so as not to overlap with the folding axis (B) when the display (210) is in an intermediate state (1720, 1730).

[0163] In one embodiment, the processor (120) can reconfigure the AOD screen based on the folding state of the display (210). For example, the electronic device (101) may have various form factor structures, such as a half-folding structure where the display (210) is folded in half, or a Z-flip folding structure where it is folded into three parts and about one-third of the way is folded. The AOD screen may be displayed on the display (210) of the electronic device (101) having various foldable form factor structures. The processor (120) may reduce degradation and / or burn-in of the display (210) by dynamically changing the attribute information of the AOD screen according to the area where the AOD screen is displayed.

[0165] FIG. 18 is a drawing (1800) showing an operation of reconstructing a first screen of a display (210) of an electronic device (101) according to another embodiment to generate a second screen.

[0166] In one embodiment, a processor (e.g., processor (120) of FIG. 1) may display a first screen, which is an AOD screen containing a first content (1811) and a second content (1812), on the display (210) when the display (210) is in an unfolded state (1810). The processor (120) may reconstruct the first screen to create a second screen when the display (210) begins to fold along the folding axis (B) and changes from an unfolded state (1810) to an intermediate state (1820).

[0167] In one embodiment, the processor (120) can generate a second screen by dividing the first content (1811) and the second content (1812) based on the folding axis (B) when changing to an intermediate state (1820). For example, the processor (120) can display the first content (1811) in the form of a view intended for the user to view in the upper area of ​​the folding axis (B), and display the second content (1812) in the form of an icon that the user can touch input in the lower area of ​​the folding axis (B).

[0168] In one embodiment, the processor (120) may divide at least some of the content displayed in an application (e.g., application (146) of FIG. 1) according to the folding angle to prevent burn-in. For example, when displaying a notification application on an AOD screen, a clock may be displayed in the upper area of ​​the display (210) with respect to the folding axis (B), and an icon may be displayed in the lower area of ​​the display (210). The processor (120) may change the display attributes of the first content (1811) and the second content (1812) respectively to reduce degradation and / or burn-in caused by the first content (1811) and the second content (1812) respectively. For example, the processor (120) may move the first content (1811) and the second content (1812) respectively at designated intervals independently.

[0170] FIG. 19 is a drawing (1900) showing an operation of reconstructing a first screen of a display (210) of an electronic device (101) according to another embodiment to generate a second screen.

[0171] In one embodiment, a processor (e.g., processor (120) of FIG. 1) may reconfigure a first screen according to the arrangement direction and / or folding shape of the electronic device (101). The processor (120) may generate a second screen by considering the shape in which the display (210) is visible according to the arrangement direction of the electronic device (101). The processor (120) may generate a second screen based on a first direction (1921) and a second direction (1922), which are the directions in which each of the displays (210) faces when the electronic device (101) is folded along the folding axis (B).

[0172] In one embodiment, the processor (120) may display an AOD screen in which the placement position of the content is reconfigured to reduce degradation and / or burn-in of the display (210) when the electronic device (101) is in a horizontally elongated state. For example, when the display (210) is in a horizontally elongated state and the folding axis (B) is formed vertically, the processor (120) may display clock content in a first area (1911) on the left and notification content in a second area (1912) on the right. When the electronic device (101) is folded at least partially along the folding axis (B), the processor (120) may set the position, size, font, and / or brightness of the content based on a first direction (1921) and a second direction (1922), which are the directions in which each of the displays (210) faces.

[0174] FIG. 20 is a drawing (2000) showing an operation of reconstructing a first screen of a display (210) of an electronic device (101) according to another embodiment to generate a second screen.

[0175] In one embodiment, a processor (e.g., processor (120) of FIG. 1) may reconstruct a first screen according to the orientation of the electronic device (101) and / or the form in which the display (210) is shown. The processor (120) may generate a second screen according to the orientation of the electronic device (101) and / or the form in which the display (210) is shown.

[0176] In one embodiment, when the electronic device (101) has a three-section foldable form factor structure, the processor (120) can display an AOD screen on one-third of the display (210) that is visible. When the electronic device (101) is oriented in a horizontally elongated direction, as in the first case (2010), the processor (120) can display the content constituting the AOD screen so that the user reads it horizontally. When the electronic device (101) is oriented in a vertically elongated direction, as in the second case (2020), the processor (120) can display the content constituting the AOD screen rotated 90 degrees compared to the first case (2010).

[0178] FIG. 21 is a drawing (2100) showing the operation of reconstructing a first screen of a display (210) of an electronic device (101) according to another embodiment to generate a second screen.

[0179] In one embodiment, a processor (e.g., processor (120) of FIG. 1) can display an AOD screen (2110) on an electronic device (101) of a table foldable form factor structure. For example, if the electronic device (101) is placed on a table in the form of a desk clock, the processor (120) can display an AOD screen (2110) including a clock, date, and / or notifications in the form of a desk clock.

[0180] In one embodiment, the processor (120) can display an AOD screen (2110) corresponding to the shape of the electronic device (101). For example, if the electronic device (101) has a slide-type structure, the processor (120) can display the AOD screen (2110) on the part visible to the user. As another example, if an external cover is attached to the electronic device (101), the processor (120) can display the AOD screen (2110) on the part visible to the user. When the shape of the electronic device (101) changes, the processor (120) can reconfigure the AOD screen (2110) to display a new AOD screen on the display (210).

[0182] FIG. 22 is a flowchart (2200) showing a method of displaying an AOD screen of a display (e.g., a display (210) of FIG. 2) of an electronic device (e.g., an electronic device (101) of FIG. 1) according to one embodiment.

[0183] A processor (e.g., processor (120) of FIG. 1) of an electronic device (101) according to one embodiment may turn on an AOD mode in operation 2210. The processor (120) may turn on an AOD mode (e.g., low-power display mode) of a display (210) in a disabled mode or sleep mode (e.g., low-power mode). The processor (120) may turn on the AOD mode to display an AOD screen on the display (210). When the electronic device (101) receives user input, the processor (120) may switch the electronic device (101) from the AOD mode to a normal mode.

[0184] In operation 2220, the processor (120) of the electronic device (101) according to one embodiment may randomize the starting point. The starting point may be a point at a designated location among the areas displaying the content of the AOD screen at the time the AOD mode is turned on. For example, the starting point may be the upper-left location among the areas displaying the content of the AOD screen at the time the AOD mode is turned on. The processor (120) may randomly set the location of the starting point.

[0185] A processor (120) of an electronic device (101) according to one embodiment can determine whether the AOD mode is off in operation 2230. If the AOD mode is off (operation 2230 - YES), the processor (120) can proceed to operation 2235. If the AOD mode remains on (operation 2230 - NO), the processor (120) can proceed to operation 2240.

[0186] In one embodiment, the processor (120) of the electronic device (101) may be switched to a normal mode in operation 2235. In the normal mode, the processor (120) may turn on the display (210) and display the execution screen of an application (e.g., the application (146) of FIG. 1). The processor (120) may switch the electronic device (101) from the normal mode to the AOD mode if a specified time has elapsed without user input to the electronic device (101).

[0187] A processor (120) of an electronic device (101) according to one embodiment can display an AOD in operation 2240. The processor (120) can display an AOD screen on a display (210). The processor (120) can determine the brightness of the AOD screen and display the AOD screen with the determined brightness.

[0188] A processor (120) of an electronic device (101) according to one embodiment may check whether a specified time interval has elapsed in operation 2250. The specified time interval may be a time interval for maintaining the degree of degradation and / or burn-in of the display (210) by the AOD screen below a threshold value. For example, when displaying a clock on the AOD screen, the processor (120) may check whether 1 minute has elapsed since the AOD screen was displayed. The processor (120) may maintain operation 2240 before the specified time interval has elapsed (operation 2250 - NO). The processor (120) may proceed to operation 2260 when the specified time interval has elapsed (operation 2250 - YES).

[0189] A processor (120) of an electronic device (101) according to one embodiment may move diagonally in operation 2260. The processor (120) may move the AOD screen diagonally. For example, when displaying a clock on the AOD screen, the processor (120) may move the AOD screen diagonally by a specified distance every time one minute elapses. The specified distance may be substantially equal to the length and / or width of one pixel.

[0190] A processor (120) of an electronic device (101) according to one embodiment can perform an AOD conversion in operation 2270. The processor (120) can repeat operation 2240 by displaying the AOD by moving the AOD screen by a specified distance diagonally from the previously displayed position.

[0192] FIG. 23 is a drawing (2300) showing a method of displaying an AOD screen of a display (e.g., a display (210) of FIG. 2) of an electronic device (e.g., an electronic device (101) of FIG. 1) according to one embodiment.

[0193] In one embodiment, a processor (e.g., processor (120) of FIG. 1) can display a first content (2310) of an AOD screen on a display (210). The top left corner of the first content (2310) can be set as a random starting point.

[0194] In one embodiment, the processor (120) may perform a first movement based on a first rule to move the first content (2310) from a starting point at specified first time intervals while displaying the first content (2310). The first rule may be a rule for setting a small jump of the first content (2310). If a position marked with 0 is a random starting point, the processor (120) may move the first content (2310) to positions 1, 2, 3, 4, 5, 6, 7, 8, 9 at specified time intervals, starting from 0. For example, when displaying a clock on an AOD screen, the processor (120) may move the top-left corner of the clock to positions 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 at each minute after displaying the clock on the AOD screen.

[0195] In one embodiment, the processor (120) may perform a second movement that moves the first content (2310) from a starting point based on a specified second rule at specified second time intervals. The second rule may be a rule that sets a big jump to reconfigure the first content (2310) into the second content (2320). The processor (120) may reconfigure the first content (2310) into the second content (2320) and display it. For example, when displaying a clock on an AOD screen, the processor (120) may move the top-left corner of the clock to a new position on the display (210) every 10 minutes after the clock is displayed on the AOD screen. The processor (120) may prevent degradation and / or burn-in of the display (210) by allowing the entire AOD screen to be displayed on the display (210).

[0197] FIG. 24 is a flowchart (2400) showing a method of displaying an AOD screen of a display (e.g., display (210) of FIG. 2) of an electronic device (e.g., electronic device (101) of FIG. 1) according to another embodiment.

When the electronic device (101) receives user input, the processor (120) may switch the electronic device (101) from the AOD mode to a normal mode.

[0199] In operation 2420, the processor (120) of the electronic device (101) according to one embodiment may randomize the starting point. The starting point may be a point at a designated location among the areas displaying the content of the AOD screen at the time the AOD mode is turned on. For example, the starting point may be the upper-left location among the areas displaying the content of the AOD screen at the time the AOD mode is turned on. The processor (120) may randomly set the location of the starting point.

[0200] A processor (120) of an electronic device (101) according to one embodiment can determine whether the AOD mode is off in operation 2430. If the AOD mode is off (operation 2430 - YES), the processor (120) can proceed to operation 2435. If the AOD mode remains on (operation 2430 - NO), the processor (120) can proceed to operation 2440.

[0201] In one embodiment, the processor (120) of the electronic device (101) may be switched to a normal mode in operation 2435. In the normal mode, the processor (120) may turn on the display (210) and display the execution screen of an application (e.g., the application (146) of FIG. 1). The processor (120) may switch the electronic device (101) from the normal mode to the AOD mode if a specified time has elapsed without user input to the electronic device (101).

[0202] A processor (120) of an electronic device (101) according to one embodiment can display an AOD in operation 2440. The processor (120) can display an AOD screen on a display (210). The processor (120) can determine the brightness of the AOD screen and display the AOD screen with the determined brightness.

[0203] A processor (120) of an electronic device (101) according to one embodiment may check whether a specified time interval has elapsed in operation 2450. The specified time interval may be a time interval for maintaining the degree of degradation and / or burn-in of the display (210) by the AOD screen below a threshold value. For example, when displaying a clock on the AOD screen, the processor (120) may check whether 1 minute has elapsed since the AOD screen was displayed. The processor (120) may maintain operation 2440 before the specified time interval has elapsed (operation 2450 - NO). The processor (120) may proceed to operation 2460 when the specified time interval has elapsed (operation 2450 - YES).

[0204] A processor (120) of an electronic device (101) according to one embodiment may move in a random direction in operation 2460. The processor (120) may move the AOD screen in any direction. For example, when displaying a clock on the AOD screen, the processor (120) may move the AOD screen in any direction by a specified distance every time one minute elapses. The random direction may be up, down, left, right, and / or diagonal. The specified distance may be substantially equal to the length and / or width of one pixel.

[0205] A processor (120) of an electronic device (101) according to one embodiment can perform an AOD conversion in operation 2470. The processor (120) can repeat operation 2440 by displaying the AOD by moving the AOD screen by a specified distance in any direction from the previously displayed position.

[0206] In one embodiment, the processor (120) may perform an AOD conversion when a threshold time has elapsed. For example, when displaying a clock on an AOD screen, the processor (120) may move the clock to an area on the display (210) that has been kept in a turn-off state every time one hour has elapsed after displaying the clock on the AOD screen. The processor (120) may prevent degradation and / or burn-in of the display (210) by allowing the AOD screen to be displayed entirely on the display (210).
