Description

Technical Field

[0001] This application relates to the field of display technology, and more particularly to a display method, electronic device, and computer-readable storage medium. Background Technology

[0002] Because each pixel of a display made of organic light-emitting materials (such as organic light-emitting diodes (OLEDs), active-matrix organic light-emitting diodes (AMOLEDs), etc.) can emit light independently, the display effect is better, and more and more electronic devices (such as foldable screen phones) are using this type of display.

[0003] However, when such displays emit light for extended periods, the organic materials in their pixels are prone to aging. If the aging of the pixels varies, abnormal screen burn-in phenomena such as image retention, color deviation, and uneven brightness may occur. Summary of the Invention

[0004] Some embodiments of this application provide a display method, an electronic device, and a computer-readable storage medium. The following describes this application from multiple aspects, and the embodiments and beneficial effects of the following aspects can be referred to each other.

[0005] In a first aspect, this application provides a display method for an electronic device, the electronic device including a first display screen, the first display screen including a first display area and a second display area connected together, the method including: the grayscale difference of the display content corresponding to the first display area and the second display area is greater than or equal to a grayscale difference threshold, and the display duration of the first display area and the second display area of ​​the first display screen reaches a duration threshold, adjusting the grayscale value of the display content of at least one of the first display area and the second display area, such that the grayscale difference of the display content of the first display area and the second display area is less than the grayscale difference threshold; wherein, the grayscale difference threshold is determined based on a temperature difference threshold, and after the display duration threshold of the two connected display areas of the first display screen, the temperature difference between the two connected display areas is less than the temperature difference threshold.

[0006] The grayscale difference threshold can be defined as the grayscale difference between the displayed content of two adjacent display areas on an electronic device's screen when the temperature difference between them reaches a certain threshold after a certain display duration. In other words, when the grayscale difference between the displayed content of two display areas on an electronic device's screen is greater than or equal to the grayscale difference threshold, and the temperature difference between these two display areas reaches a certain threshold after a certain display duration, the screen will exhibit burn-in abnormalities.

[0007] The temperature difference threshold can be the predicted temperature difference at which the first display screen will experience burn-in when two adjacent display areas of the first display screen are displayed simultaneously for a duration that reaches the threshold.

[0008] When there is a significant grayscale difference between the displayed content in two adjacent display areas (first and second display areas) on the first display screen of an electronic device, a prolonged display time in these two areas may lead to a large temperature difference. This uneven heating of pixels at the boundary between the first and second display areas makes them more prone to aging, potentially causing screen burn-in. Therefore, when the grayscale difference between the displayed content in the first and second display areas is large, the grayscale values ​​of the displayed content in both areas can be adjusted to reduce the grayscale difference, thereby lowering the temperature difference and preventing screen burn-in.

[0009] Specifically, when the grayscale difference between the displayed content in the first display area and the second display area is greater than or equal to a grayscale difference threshold, and the display duration in the first display area and the second display area reaches a duration threshold, the grayscale values ​​of the first display area and / or the second display area are adjusted so that the grayscale difference between the displayed content in the first display area and the second display area is less than the grayscale difference threshold. This reduces the grayscale difference between the displayed content in the first display area and the second display area, thereby reducing the temperature difference between the first display area and the second display area, and consequently reducing the risk of screen burn-in on the first display screen.

[0010] Taking a foldable screen phone as an example, with the first display screen being the outer screen of the foldable screen phone, the first display area being area C mentioned below in this application, and the second display area being the video playback area in area B mentioned below in this application:

[0011] The foldable phone displays the video playback interface of a short video app in area B of the outer screen, and system information in area C. Both areas C and B have a black background with a grayscale value of 0. The video played by the short video app is displayed within the video playback area in area B, which is adjacent to area C. The background image of the video playback area is white with a grayscale value of 255. The grayscale difference between the background images of area C and the video playback area in area B is 255.

[0012] Assuming a duration threshold of 30 minutes and a grayscale difference threshold of 240, when the display duration of areas C and B on the outer screen of a foldable phone reaches 30 minutes, the grayscale value of the background image in area C can be adjusted from 0 to 32. After adjustment, the grayscale difference between the background image in area C and the background image in the video playback area of ​​area B is 223, which is less than the grayscale difference threshold of 255. This reduces the brightness difference between the video playback areas in areas C and B, thereby reducing the temperature difference between these areas and ultimately lowering the risk of screen burn-in on the outer screen of the foldable phone.

[0013] In some implementations, the grayscale difference between the displayed content in the first display area and the second display area is the absolute value of the difference between the first grayscale value of the first background image in the first display area and the second grayscale value of the second background image in the second display area.

[0014] Continuing with the example of a foldable screen phone, where the first display screen is the outer screen of the foldable screen phone, the first display area is area C mentioned below in this application, and the second display area is the video playback area in area B mentioned below in this application:

[0015] When the grayscale value of the background image displayed in area C is 0 (as an example of the first grayscale value), and the grayscale value of the background image of the video playback area in area B is 255 (as an example of the second grayscale value), the grayscale difference between the background image of area C and the background image of the video playback area in area B is: |0-255|=255.

[0016] In some embodiments, adjusting the grayscale value of the displayed content in at least one of the first display area and the second display area, such that the grayscale difference between the displayed content in the first display area and the second display area is less than a grayscale difference threshold, includes:

[0017] The grayscale value of the first background image in the first display area is adjusted from the first grayscale value to the third grayscale value, wherein the absolute value of the difference between the third grayscale value and the second grayscale value is less than the grayscale difference threshold.

[0018] Continuing with the example of a foldable screen phone as the electronic device, the first display screen as the outer screen of the foldable screen phone, the first display area as area C mentioned in this application, and the second display area as the video playback area in area B mentioned in this application:

[0019] The foldable phone displays the video playback interface of a short video app in area B of the outer screen, and system information in area C. Both areas C and B have a black background with a grayscale value of 0. The video played by the short video app is displayed within the video playback area in area B, which is adjacent to area C. The background image of the video playback area has a white background with a grayscale value of 255. The grayscale difference between the background images of area C and the video playback area in area B is 255.

[0020] Assuming a duration threshold of 30 minutes and a grayscale difference threshold of 240, when the display duration of areas C and B on the outer screen of a foldable phone reaches 30 minutes, the grayscale value of the background image in area C can be adjusted from 0 grayscale (as an example of the first grayscale value) to 32 grayscale (as an example of the third grayscale value). After adjustment, the grayscale difference between the background image in area C and the background image in the video playback area of ​​area B is 223, which is less than the grayscale difference threshold of 255. This reduces the brightness difference between the video playback areas in areas C and B, thereby reducing the temperature difference between the video playback areas in areas C and B, and thus reducing the risk of screen burn-in on the outer screen of the foldable phone.

[0021] In some embodiments, a first element is displayed on a first background image, the first element has the same color as the first background image, and the grayscale value of the first element is a third grayscale value. The method further includes: adjusting the grayscale value of the first element from the third grayscale value to a fourth grayscale value; and / or adjusting the color of the first element to a color different from that of the first background image.

[0022] The first element can be user interface (UI) elements such as time, date, weather, battery icon, signal strength icon, Wi-Fi network icon, and notification bar.

[0023] Continuing with the example of a foldable screen phone as the electronic device, the first display screen as the outer screen of the foldable screen phone, the first display area as area C mentioned in this application, and the second display area as the video playback area in area B mentioned in this application:

[0024] The foldable phone displays the video playback interface of a short video app in area B of the outer screen, and system information in area C. Both areas C and B have a black background with a grayscale value of 0. The UI elements in area C are also black, but with a grayscale value of 32. The video played by the short video app is displayed within the video playback area in area B, which is adjacent to area C. The background image of the video playback area is white with a grayscale value of 255. The grayscale difference between the background images in area C and the video playback area in area B is 255.

[0025] Assuming a duration threshold of 30 minutes and a grayscale difference threshold of 240, when the display duration of areas C and B on the outer screen of a foldable phone reaches 30 minutes, the grayscale value of the background image in area C can be adjusted from 0 to 32, and the grayscale value of the UI elements on the background image in area C can be adjusted from 32 to 48 (as an example of the first grayscale value), and / or, the color of the UI elements on the background image in area C can be adjusted to blue. This avoids the UI elements on the background image from blending together with the background image due to identical color and grayscale values ​​after the grayscale value adjustment, preventing users from clearly seeing the UI elements and affecting their ability to view system information.

[0026] In some embodiments, the first display screen includes at least one punch hole, a first display area covers the at least one punch hole, a second display area does not cover the at least one punch hole, and a camera is disposed at the punch hole.

[0027] Continuing with the example of a foldable phone, where the first display is the outer screen of the foldable phone, the outer screen includes at least one punch-hole. Area C covers this punch-hole, while area B does not. Correspondingly, the video playback area within area C does not cover the punch-hole.

[0028] In some embodiments, the electronic device further includes a second display screen, which is disposed opposite to the first display screen on two different planes of the electronic device, and the second display screen is a foldable screen.

[0029] The electronic device may be a foldable screen phone mentioned in this application, the first display screen may be the outer screen of the foldable screen phone, and the second display screen may be the inner screen of the foldable screen phone.

[0030] Secondly, embodiments of this application provide an electronic device, including: a memory for storing instructions executable by one or more processors of the electronic device; and a processor, which, when executing the instructions in the memory, causes the electronic device to perform the method described in the first aspect of this application. The beneficial effects achievable in the second aspect can be found in the beneficial effects of the method provided in any embodiment of the first aspect, and will not be repeated here.

[0031] Thirdly, embodiments of this application provide a computer-readable storage medium storing instructions that, when executed on a computer, cause the computer to perform the method described in any embodiment of the first aspect. The beneficial effects achievable through this third aspect can be referenced to the beneficial effects of the method provided in any embodiment of the first aspect, and will not be repeated here.

[0032] Fourthly, embodiments of this application provide a computer program product including computer program code. When the computer program code is run on a computer, it causes the computer to implement the method described in any embodiment of the first aspect. The beneficial effects achievable in this fourth aspect can be found in the beneficial effects of the method provided in any embodiment of the first aspect, and will not be repeated here.

[0051] Figure 17 A schematic diagram of the structure of an electronic device provided in an embodiment of this application is shown. Detailed Implementation

[0052] This application provides a display method. The display method provided by this application is described below with reference to specific embodiments.

[0053] For ease of understanding, the terms used in this application are explained below.

[0054] (1) Grayscale

[0055] Grayscale refers to the brightness levels of an image, which can be divided into multiple (e.g., 8, 32, 64, 128, 256, etc.) brightness levels, from the darkest (e.g., pure black) to the brightest (e.g., pure white). The following explanation uses 256 brightness levels, from the darkest (0 grayscale) to the brightest (255 grayscale), as an example.

[0056] As described in the background section, for displays made of organic light-emitting materials such as OLED and AMOLED displays, if the aging degree of the pixels in the display is different, abnormal burn-in phenomena such as image retention, color deviation, and uneven brightness may occur. The following explanation uses OLED displays as an example.

[0057] Figure 1 This is an exemplary application scenario of this application.

[0058] refer to Figure 1 The electronic device's OLED display shows image 01 and image 02 in two different display areas. Image 01 is pure black with a grayscale value of 0. Image 02 is pure white with a grayscale value of 255.

[0059] In some cases, after a period of time, such as 30 minutes, when the OLED display of an electronic device displays a pure white image in full screen, a ghost image appears on the OLED display. This ghost image is located at the boundary between the two display areas where image 01 and image 02 are located.

[0060] This is because the grayscale difference between image 01 and image 02 (i.e., the absolute value of the difference between the grayscale values ​​of image 01 and image 02, specifically 255) is relatively large, resulting in a large brightness difference between the two display areas where image 01 and image 02 are located. Therefore, after displaying image 01 and image 02 on the OLED screen of an electronic device for an extended period, the temperature difference between the two display areas will become too large, causing uneven heating of the pixels at the boundary between these two display areas. Pixels with uneven heating are more prone to aging. Consequently, after prolonged display on the OLED screen of an electronic device, the pixels at the boundary between the two display areas of image 01 and image 02 age more rapidly than pixels in other areas, resulting in image ghosting at the boundary between the two display areas of image 01 and image 02.

[0061] In view of this, this application provides a display method. In this method, when the grayscale difference (i.e., the absolute value of the difference between the grayscale values ​​of the content displayed in two adjacent display areas of an electronic device's display screen (such as an OLED display screen) is large, and the display duration of these two display areas is long, the grayscale value of the content displayed in at least one of these two areas can be adjusted to reduce the grayscale difference between the content displayed in these two display areas, thereby reducing the brightness difference between the two display areas, and further reducing the temperature difference between the two display areas, thus preventing screen burn-in at the pixel points at the junction of these two display areas due to uneven heating.

[0062] Specifically, when an electronic device displays two images with different grayscale values ​​in two different display areas, if the grayscale difference between the two images is greater than or equal to a grayscale difference threshold (e.g., 240, 250, etc., without limitation), and the display duration is greater than a duration threshold, the grayscale value of at least one of the two images can be adjusted so that the grayscale difference between the two images is less than the grayscale difference threshold. The grayscale difference threshold is determined based on a temperature difference threshold (e.g., 10℃, 20℃, etc.), and after the display duration threshold is reached for two adjacent display areas on the electronic device's screen, the temperature difference between the two adjacent display areas is less than the temperature difference threshold.

[0063] In some embodiments, the temperature difference threshold is the predicted temperature difference at which screen burn-in occurs when two adjacent display areas on the screen of an electronic device are displayed simultaneously for a duration threshold (e.g., 30 minutes, 35 minutes, 40 minutes, etc.). The predicted temperature difference is the temperature difference that is expected to cause screen burn-in when two adjacent display areas on the screen of an electronic device are displayed simultaneously for a duration threshold.

[0064] In some embodiments, the grayscale difference threshold can be the grayscale difference of the displayed content in two adjacent display areas on the screen of an electronic device when the temperature difference between them reaches a temperature difference threshold. That is, when the grayscale difference of the displayed content in two display areas on the screen of an electronic device is greater than or equal to the grayscale difference threshold, the display time of these two display areas reaches a time limit threshold, and the temperature difference between these two display areas reaches a temperature difference threshold, resulting in screen burn-in.

[0065] For example, refer to Figure 2 ,for Figure 1As shown in the scenario, assuming a duration threshold of 30 minutes and a grayscale difference threshold of 240, when the display duration of the OLED screen of the electronic device reaches 30 minutes, the grayscale value of image 01 can be adjusted from grayscale 0 to grayscale 32 to reduce the grayscale difference between image 01 and image 02. This makes the grayscale difference between image 01 and image 02 less than the grayscale difference threshold, thereby reducing the brightness difference between the two display areas where image 01 and image 02 are located, and further reducing the temperature difference between these two display areas, thus preventing screen burn-in at the boundary between these two display areas.

[0066] It should be noted that in this application, grayscale difference is equal to the absolute value of the difference between two grayscale values, brightness difference is equal to the absolute value of the difference between two brightness values, and temperature difference is equal to the absolute value of the difference between two temperature values. That is, grayscale difference, brightness difference, and temperature difference are all values ​​greater than or equal to 0, and will not be elaborated further below.

[0067] It should be noted that the electronic devices in this application include, but are not limited to, foldable screen devices (such as vertically foldable screen phones or horizontally foldable screen phones), tablets, computers, smart wearable devices (such as smartwatches and smart bracelets), in-vehicle devices (such as in-vehicle tablets), and other terminal devices including displays made of organic light-emitting materials.

[0068] Understandable. Figure 2 The images 01 and 02 shown can be the content of different application windows displayed on an electronic device. For example, two application interfaces displayed on a tablet through split screen or floating window, or the content displayed in the top status bar of the display screen and the application interface displayed on the display screen, or the system interface and application interface displayed on the outer screen of a foldable phone in two adjacent display areas, etc.

[0069] For ease of explanation, the following text will use a vertically foldable screen phone as an example of an electronic device.

[0070] Figure 3A (1) shows an exemplary schematic diagram of the front (the side of the phone with the folding screen) of a foldable phone in its fully unfolded state; Figure 3A (2) in the example shows a schematic diagram of the back (the side of the phone casing) of a foldable phone when it is fully unfolded.

[0071] like Figure 3AAs shown, the foldable phone 100 includes an inner screen 10, an outer screen 20, and a casing 30. The inner screen 10 and outer screen 20 are OLED displays. Furthermore, the inner screen 10 is a flexible screen that can be folded along the folding edge L1. The inner screen 10 and outer screen 20 are disposed opposite each other on two different planes of the foldable phone 100. The outer screen 20 and casing 30 are disposed on the same plane of the foldable phone 100. The outer screen 20 has a cutout, and one or more cameras 40 are disposed at the cutout. When the foldable phone 100 is in its fully unfolded state, the inner screen 10 is lit, and the outer screen 20 is turned off. The cameras 40 can be used as the rear cameras of the foldable phone 100 for taking pictures.

[0072] Figure 3B An example diagram is shown of a foldable screen phone 100 folded inward to a fully folded state.

[0073] In some embodiments, such as Figure 3B As shown, the foldable phone 100 can fold inward along the folding edge L1. When the foldable phone 100 is folded inward to its fully folded state, the outer screen 20 of the foldable phone 100 lights up, while the inner screen 10 turns off. The camera 40 can be used as the front-facing camera of the foldable phone 100 for taking pictures.

[0074] Figure 3C An example diagram is shown of a foldable phone 100 displaying an application interface in a fully folded state.

[0075] In some embodiments, when the foldable phone 100 displays the interface of an application (such as a short video application, instant messaging application, meeting application, game application, or other third-party application, or a system application such as weather, calendar, alarm clock, voice recorder, telephone, gallery, etc.) in its fully folded state, the application interface can be displayed in full screen on the outer screen 20. For example, as Figure 3C As shown, when the foldable phone 100 is fully folded, it can display the video playback interface of a short video application in full screen on the outer screen 20.

[0076] However, because there is a punch-hole on the outer screen 20, when the video playback interface of the short video application is displayed in full screen on the outer screen 20, the content of the video playback interface in the punch-hole area of ​​the outer screen 20 cannot be displayed, causing users to be unable to watch the complete video content.

[0077] In some embodiments, to avoid missing content displayed on the outer screen 20 of the foldable phone 100 when it is in a fully folded state, when the foldable phone 100 displays an application interface on the outer screen 20 in a fully folded state, the outer screen 20 of the foldable phone 100 can avoid the punch-hole area on the outer screen 20 and display the application interface in a partial area of ​​the outer screen 20, instead of displaying the application interface in the full screen.

[0078] For example, such as Figure 4 As shown, the entire display area of ​​the outer screen 20 of the foldable phone 100 can be divided into area B and area C (or "deco area"). Area B does not cover the punch-hole area, while area C does. When the foldable phone 100 is in its fully folded state and displays an application interface, the foldable phone 100 can display the application interface within area B of the outer screen 20.

[0079] For example, such as Figure 5 As shown, when the foldable phone 100 displays the video playback interface of a short video application in its fully folded state, the foldable phone 100 can display the video playback interface of the short video application in area B of the outer screen 20. In this way, the foldable phone 100 can display the complete video playback interface in area B, avoiding any missing content.

[0080] In some embodiments, in order to make full use of the display function of the C area of ​​the outer screen 20 of the foldable screen phone 100, when the foldable screen phone 100 displays the video playback interface of the short video application in the B area of ​​the outer screen 20, the foldable screen phone 100 can display the system interface in the C area of ​​the outer screen 20. The system interface includes system information such as time, date, battery level, and signal status.

[0081] It is understandable that when the background colors of areas B and C of the outer screen 20 of the foldable phone 100 are different, the display of the image on the outer screen 20 will have a strong sense of disjointedness, resulting in a poor viewing experience for the user.

[0082] Based on this, in some embodiments, when the foldable screen phone 100 displays an application interface in area B of the outer screen 20, the foldable screen phone 100 can detect the background color of the application interface, and then display a background image with the same background color as the application interface in area C of the outer screen 20. Then, UI elements such as time, date, weather, battery icon, signal strength icon, Wi-Fi network icon, and notification bar can be displayed on the background image.

[0083] For example, such as Figure 6 As shown, when the foldable phone 100 displays a short video app's video playback interface in area B of the outer screen 20, the foldable phone 100 detects that the background color of the short video app's video playback interface in area B of the outer screen 20 is pure black (grayscale value of 0). In this case, the foldable phone 100 can display a pure black background image in area C of the outer screen 20, and display system information such as time, date, battery level, and signal status on this background image. This ensures that the background colors of areas B and C are consistent, reducing the sense of disjointedness in the display on the outer screen 20 and improving the user's viewing experience.

[0084] However, the grayscale difference between the background image in area B (the area where short video applications play videos) and the background image displayed in area C is significant, resulting in a correspondingly large brightness difference. Consequently, when the outer screen 20 of the foldable phone 100 is used for an extended period, the temperature difference between area B (the video playback area) and area C of the outer screen 20 may become excessive, leading to screen burn-in and ghosting at the boundary between these two areas.

[0085] Specifically, such as Figure 6 As shown, in the outer screen 20 of the foldable phone 100, the N (N is a positive integer greater than or equal to 1) columns of pixels (hereinafter referred to as pixels c) in area C, which are connected to the video playback area of ​​area B, display pure black. These pixels are in a power-off state when displaying pure black, do not emit light, and therefore do not generate heat. However, the pixels in the video playback area of ​​area B are emitting light and correspondingly generate heat. This results in a large temperature difference on both sides of the M (M is a positive integer greater than or equal to 1) columns of pixels (hereinafter referred to as pixels b) in the video playback area of ​​area B, which are connected to area C, leading to uneven heating of pixel b. With uneven heating of pixel b, if pixel b emits light for a long time, it is more prone to aging than other pixels. When the aging degree of pixel b on the outer screen 20 of the foldable phone 100 is higher than that of other pixels, under the same voltage and current, the brightness of pixel b will be lower than that of other pixels, exhibiting a burn-in effect with image retention, affecting the user's viewing experience.

[0086] For example, such as Figure 7 As shown, on the outer screen 20 of the foldable phone 100... Figure 6 In the scenario shown, after a long period of display, when the outer screen 20 displays a pure white image in full screen, the area where pixel b is located on the outer screen 20 shows a gray afterimage.

[0087] It is understandable that in the outer screen 20 of the foldable phone 100, the greater the grayscale difference between the background image of the video playback area in area B and the background image in area C, the greater the brightness difference between pixel b in area B and pixel c in area C. Consequently, the temperature difference after displaying for a period of time will be greater, and the risk of screen burn-in will be greater.

[0088] The following uses 0 grayscale, 16 grayscale, 32 grayscale, and 48 grayscale as examples to introduce the burn-in risk levels when the outer screen 20 of the foldable phone 100 displays background images of different grayscale levels in area C. The hexadecimal color code for 0 grayscale is #000000. The hexadecimal color code for 16 grayscale is #101010. The hexadecimal color code for 32 grayscale is #202020. The hexadecimal color code for 48 grayscale is #303030.

[0089] Figure 8 The image shows the display effect of the background color of area C of the outer screen 20 of the foldable phone 100 at 0 grayscale, 16 grayscale, 32 grayscale, and 48 grayscale. Figure 8 (1) shows the display effect of the background color of area C of the outer screen 20 of the foldable phone 100 being 0 grayscale. Figure 8 (2) shows the display effect of the background color of the C area of ​​the outer screen 20 of the foldable screen phone 100 being 16 gray levels. Figure 8 (3) shows the display effect of the background color of area C of the outer screen 20 of the foldable screen phone 100 being 32 gray levels. Figure 8 (4) shows the display effect of the background color of area C of the outer screen 20 of the foldable screen phone 100 with 48 gray levels.

[0090] like Figure 8 As shown, the larger the grayscale of the background image in area C of the outer screen 20 of the foldable phone 100, the brighter area C is, and the closer the brightness of area C and the video playback area in area B are, resulting in a smaller temperature difference. Therefore, the temperature difference between pixels located at the boundary between the video playback area in area B and area C, and on either side of pixel b within that video playback area, is smaller, thus reducing the risk of screen burn-in. Conversely, the smaller the grayscale of the background color in area C of the outer screen 20 of the foldable phone 100, the lower the brightness of area C, and the greater the brightness difference between area C and the video playback area in area B, resulting in a larger temperature difference. Therefore, the temperature difference between pixels located at the boundary between the video playback area in area B and area C, and on either side of pixel b within that video playback area, is larger, thus increasing the risk of screen burn-in.

[0091] Therefore, as Figure 9 As shown, the smaller the grayscale of the background image displayed in area C of the outer screen 20 of the foldable phone 100, the lower the brightness of area C, resulting in a better user experience, but also a higher risk of screen burn-in. Conversely, the larger the grayscale of the background color displayed in area C of the outer screen 20 of the foldable phone 100, the higher the brightness of area C, resulting in a worse user experience, but also a lower risk of screen burn-in.

[0092] Based on this, in some embodiments, when the foldable screen phone 100 detects that the grayscale difference between the background image of region C and the background image of the video playback area in region B of the outer screen 20 is greater than or equal to a grayscale difference threshold, and when the display duration of the outer screen 20 reaches a duration threshold, the grayscale value of the background image of region C can be adjusted from the first grayscale to the second grayscale, so that the grayscale difference between the background image of region C and the background image of the video playback area in region B is less than the grayscale difference threshold. Wherein, the second grayscale is greater than the first grayscale.

[0093] For example, such as Figure 10 As shown, for Figure 6 As shown, when the foldable screen phone 100 detects that the duration of displaying a pure black background image in area B of the outer screen 20 reaches 30 minutes (as an example of the duration threshold), the foldable screen phone 100 can switch the pure black background image from 0 grayscale (as an example of the first grayscale) to 32 grayscale (as an example of the second grayscale) to increase the brightness of area B, reduce the temperature difference between the two sides of pixel b in area C, thereby reducing the aging risk of pixel b, and thus reducing the risk of screen burn-in of the outer screen 20.

[0094] In some cases, the background image of area C on the outer screen 20 of the foldable phone 100 displays UI elements with the same color as the background image and a grayscale value of the second grayscale level. In this situation, when the foldable phone 100 switches the background image of area C to the second grayscale level, these UI elements become completely identical in color and grayscale value to the background image, causing them to blend into the background image and become difficult for the user to see.

[0095] For example, such as Figure 11 As shown, the background image displayed in area C of the outer screen 20 of the foldable phone 100 is 0 grayscale black, and this background image displays UI elements with 48 grayscale black, such as the Wi-Fi icon, signal strength icon, battery icon, and time. When the foldable phone 100 switches the background image of area C of the outer screen 20 from 0 grayscale to 48 grayscale, the colors of these UI elements and the background image completely blend together, making it impossible for the user to clearly see the UI elements displayed in area C.

[0096] Based on this, in some embodiments, when the foldable screen phone 100 switches the grayscale of the background color in area C from the first grayscale to the second grayscale, if there is a UI element displayed in area C that has the same color as the background image and a grayscale value of the second grayscale, then the grayscale of that UI element is adjusted to the third grayscale, and / or the color of that UI element is adjusted to another color different from the background image in area C. Wherein, the third grayscale is not equal to the second grayscale.

[0097] For example, such as Figure 12 As shown, the background image displayed in area C of the outer screen 20 of the foldable phone 100 is black with a grayscale of 0, and UI elements with a grayscale of 48 are displayed in this background image. When the foldable phone 100 switches the background image displayed in area C of the outer screen 20 from grayscale 0 to grayscale 48, the foldable phone 100 can switch the grayscale of the UI elements with a grayscale of 48 to grayscale 64 in this background image.

[0098] For example, such as Figure 13As shown, the background image displayed in area C of the outer screen 20 of the foldable phone 100 is black with a grayscale of 0, and UI elements with a grayscale of 48 are displayed in this background image. When the foldable phone 100 switches the background image displayed in area C of the outer screen 20 from grayscale 0 to grayscale 48, the foldable phone 100 can switch the color of the UI elements with a grayscale of 48 from black to another grayscale color, such as blue.

[0099] In some embodiments, the application framework layer of the foldable phone 100 includes an application framework and a window management service. The application framework is used to draw the application interface and perform intelligent color picking. The window management service is used to manage windows, such as setting the background color within a window.

[0100] Figure 14 This application provides a flowchart of a display method.

[0101] like Figure 14 As shown, the method includes:

[0102] S101: The application framework draws the application interface for area B.

[0103] In some embodiments, when the foldable screen phone 100 displays an application interface in area B of the outer screen 20, the application framework of the foldable screen phone 100 can draw the application interface and display the application interface in area B of the outer screen 20.

[0104] For example, as mentioned above Figure 6 As shown, when the foldable screen phone 100 displays the video playback interface of a short video application in area B of the outer screen 20, the foldable screen phone 100 can draw the video playback interface and display it in area B of the outer screen 20.

[0105] S102: Use the application framework to obtain the color values ​​of the B region image.

[0106] In some embodiments, after the application interface displayed in area B of the outer screen 20 is drawn in the application framework of the foldable screen phone 100, the image displayed in the application interface can be intelligently color sampled, for example, the color value of the background image of the application interface can be intelligently obtained.

[0107] For example, as described above Figure 6 As shown, when the foldable screen phone 100 displays the video playback interface of the short video application in area B of the outer screen 20, since the background color of the video playback interface is pure black, the application framework of the foldable screen phone 100 takes the background color of the video playback interface and obtains the color value #000000.

[0108] S103: The application framework sends the color values ​​of the B region image to the window management service.

[0109] In some embodiments, the application framework of the foldable screen phone 100 obtains the corresponding color value by sampling the background color of area B, and then sends the color value to the window management service.

[0110] S104: Background color of the C area for window management service decision.

[0111] In some embodiments, after receiving the color value sent by the application framework, the window management service of the foldable screen phone 100 decides the background color of area C based on the settings of the application list, theme color, and default color.

[0112] It's understandable that the app list is pre-designed and stored in the foldable phone's storage. The apps in the list are those that can be displayed in area B, and the background color of area C is determined based on the background color of area B when displayed.

[0113] In other words, when the application interface displayed in area B of the foldable phone 100 is an application from the application list, the background color of area C of the foldable phone 100 can change along with the background color of the application interface displayed in area B, maintaining consistency with the background color of area B. However, when the application interface displayed in area B of the foldable phone 100 is not an application from the application list, the background color of area C of the foldable phone 100 is a default color (such as white), and cannot change along with the background color of the application interface displayed in area B.

[0114] In some embodiments, if the application displayed on area B of the outer screen 20 of the foldable phone 100 is in the application list, and the background color of area C is not set to the theme color or the default color, the window management service can set the background color of area C to the color value sent by the application framework after receiving the color value. For example, if the color value received by the window management service is #000000, the window management service can set the background color of area C to pure black.

[0115] S105: Window management service sets the color of the background image in area C.

[0116] In some embodiments, after the window service determines the background color of region C, the window service can set the background image of region C to that background color.

[0117] For example, as described above Figure 6As shown, when the window service determines that the background color value of area C is #000000, the window service can set the background image color of area C of the outer screen 20 of the foldable screen phone 100 to pure black.

[0118] S106: The window management service determines whether the grayscale difference between the displayed images in regions B and C is greater than or equal to the grayscale difference threshold. If yes, proceed to S107. If no, no action is taken.

[0119] In some embodiments, when the window management service determines that the grayscale difference between the images displayed in areas B and C is greater than or equal to a grayscale difference threshold, it indicates that the outer screen 20 of the foldable phone 100 has a risk of screen burn-in, and S107 needs to be executed subsequently. When the window management service determines that the grayscale difference between the images displayed in areas B and C is less than a grayscale difference threshold, it indicates that the outer screen 20 of the foldable phone 100 does not have a risk of screen burn-in, and no processing is required.

[0120] S107: The window management service times the display time of area C.

[0121] In some embodiments, after the window management service sets the color of the background image of area C, the window management service can start timing to record the display duration of the background image of area C.

[0122] S108: The window management service determines whether the display duration of area C has reached the duration threshold.

[0123] If yes, then execute S109. If no, then execute S107 to continue timing.

[0124] In some embodiments, during the window management service timing process, the window management service can determine whether the display duration of area C has reached the duration threshold. If the duration threshold has not been reached, it means that the outer screen 20 of the foldable screen phone 100 does not have a risk of screen burn-in and no processing is required. If the duration threshold has been reached, it means that the outer screen 20 of the foldable screen phone 100 has a risk of screen burn-in and S109 needs to be executed.

[0125] S109: The window management service adjusts the grayscale value of the background image in area C.

[0126] In some embodiments, when the window management service determines that the display duration of area C has reached a duration threshold, such as 30 minutes, the window management service can adjust the grayscale value of the background image of area C so that the grayscale difference between the images displayed in area C and area B is less than the grayscale difference threshold, thereby preventing screen burn-in on the outer screen 20 of the foldable phone 100.

[0127] For example, as shown in the figure above Figure 10As shown, the window management service can adjust the grayscale value of the background image in area C from grayscale 0 to grayscale 32 to reduce the grayscale difference between the background image in area C and the background image in the video playback area in area B, thereby preventing screen burn-in on the outer screen 20 of the foldable phone 100.

[0128] In this embodiment, when the C area of ​​the outer screen 20 of the foldable screen phone 100 displays a pure black background image for a long time, the foldable screen phone 100 increases the grayscale value of the background image to reduce the risk of screen burn-in of the foldable screen phone 100.

[0129] It is understandable that, in the aforementioned Figures 5 to 8 , Figures 10 to 11 In the illustrated embodiment, the third-party application interface is displayed in area B of the outer screen 20 of the foldable phone 100. The foldable phone 100 cannot adjust the grayscale value of the background image of the third-party application; therefore, the foldable phone 100 can only adjust the background image in area C.

[0130] In other embodiments, when a system application is displayed in area B of the outer screen 20 of the foldable phone 100, the foldable phone 100 may adjust the background image of area B.

[0131] For example, refer to Figure 15 The video playback interface of the video player (system application) is displayed in area B of the outer screen 20 of the foldable phone 100, and its background image is also pure black. Since the video player is a system application, when the foldable phone 100 detects that the pure black background image displayed in area C has lasted for 30 minutes, it can adjust the grayscale value of the background images in areas C and B from grayscale 0 to grayscale 32 simultaneously.

[0132] Figure 16 A flowchart of another display method provided in an embodiment of this application.

[0133] like Figure 16 As shown, the method includes:

[0134] S201: The electronic device displays different content in the first display area and the second display area of ​​the first display screen, wherein the first display area and the second display area are connected.

[0135] It is understood that the first display screen of an electronic device can be an OLED display, an AMOLED display, or other display screens made of organic light-emitting materials, and each pixel of the display screen can emit light independently.

[0136] In some embodiments, the electronic device may divide the entire display area of ​​the first display screen into two or more display areas, and take any two adjacent display areas as the first display area and the second display area, and then display different content in the first display area and the second display area respectively, such as displaying different application interfaces.

[0137] It should be noted that this application does not limit the size, shape, or position of the first display area and the second display area.

[0138] For example, as described above Figure 6 As shown, when the foldable phone 100 (as an example of an electronic device) is in a fully folded state, the foldable phone 100 can display system information such as a Wi-Fi icon, signal strength icon, battery icon, and time in area C (as an example of a first display area) of the outer screen 20 (as an example of a first display area of ​​an electronic device), and display a video played by a short video application in the video playback area (as an example of a second display area) of area B of the outer screen 20. The video playback areas in areas C and B are adjacent.

[0139] S202: The electronic device determines whether the grayscale difference between the displayed content of the first display area and the second display area is greater than or equal to the grayscale difference threshold.

[0140] If yes, then execute S203; otherwise, do nothing.

[0141] In some embodiments, the electronic device can determine whether the grayscale difference between the displayed content in the first display area and the second display area is greater than or equal to a grayscale difference threshold. If the grayscale difference between the displayed content in the first display area and the second display area is greater than or equal to the grayscale difference threshold, it indicates that the first display screen of the electronic device has a risk of burn-in, and further judgment needs to be performed in S203. Conversely, if the grayscale difference between the displayed content in the first display area and the second display area is less than the grayscale difference threshold, it indicates that the first display screen of the electronic device does not have a risk of burn-in, and no processing is required.

[0142] In some embodiments, the grayscale value of the displayed content in the first display area may be the average grayscale value of N columns of pixels located within the first display area and adjacent to the second display area, for example... Figure 6 The average grayscale value of pixel c within region C can also be the average grayscale value of the entire displayed content within the first display region; there is no limitation on this. Similarly, the grayscale value of the displayed content in the second display region can be the average grayscale value of M columns of pixels located within the second display region and adjacent to the first display region, for example... Figure 6The average grayscale value of pixel b within the video playback area of ​​region B can also be the average grayscale value of the entire display content within the second display area; there is no limitation on this.

[0143] S203: The electronic device determines whether the display duration of the first display area and the second display area of ​​the first display screen has reached the duration threshold.

[0144] If yes, then execute S204; otherwise, re-execute S203.

[0145] In some embodiments, after the electronic device determines that the grayscale values ​​of the displayed content in the first display area and the second display area are greater than or equal to a grayscale difference threshold, the electronic device can determine whether the display duration of the first display area and the second display area of ​​the first display screen has reached a duration threshold. When the electronic device determines that the display duration of the first display area and the second display area of ​​the first display screen has reached the duration threshold, it indicates that the first display screen of the electronic device has a risk of burn-in, and the anti-burn-in measures described in S204 need to be executed to avoid burn-in of the first display screen of the electronic device. When the electronic device determines that the display duration of the first display area and the second display area of ​​the first display screen has not reached the duration threshold, it indicates that the first display screen of the electronic device does not currently have a risk of burn-in, and S203 can be executed to determine whether the display duration of the first display area and the second display area of ​​the first display screen has reached the duration threshold.

[0146] S204: The electronic device adjusts the grayscale value of the display content in at least one of the first display area and the second display area so that the grayscale difference between the display content in the first display area and the second display area is less than the grayscale difference threshold.

[0147] In some embodiments, when the electronic device determines that the grayscale difference between the display content of the first display area and the second display area of ​​the first display screen is greater than or equal to a grayscale difference threshold, and the display duration of the first display area and the second display area of ​​the first display screen reaches a duration threshold, the electronic device may adjust the grayscale value of the display content of at least one display area in the first display area and the second display area so that the grayscale difference between the display content of the first display area and the second display area is less than the grayscale difference threshold.

[0148] Taking a grayscale difference threshold of 240 and a duration threshold of 30 minutes as an example:

[0149] Regarding the above Figure 2In the scenario shown, the first display screen of an electronic device displays images 01 and 02 in two adjacent display areas (designated as the first display area and the second display area). Image 01 is a pure black image with a grayscale value of 0, and image 02 is a pure white image with a grayscale value of 255. The grayscale difference of 255 is greater than the grayscale difference threshold of 240, posing a certain risk of screen burn-in. When the display time in these two display areas reaches 30 minutes, the electronic device can adjust the grayscale value of image 01 from 0 to 32, making the grayscale difference between image 01 and image 02 (specifically 223) less than the grayscale difference threshold (specifically 240). This reduces the temperature difference between the two display areas, thereby reducing the risk of screen burn-in at the boundary between the two display areas and preventing screen burn-in of the first display screen.

[0150] Continuing with the example of a grayscale difference threshold of 240 and a duration threshold of 30 minutes:

[0151] Regarding the above Figure 10 In the scenario shown, area C of the outer screen 20 of the foldable phone 100 displays a pure black background image with a grayscale value of 0. The average grayscale value of pixel c, which is adjacent to the video playback area B in area C, is 0 (serving as the grayscale value of the content displayed in area C). The video playback area B of the outer screen 20 of the foldable phone 100 displays a video played by a short video application. The average grayscale value of pixel b, which is adjacent to area C in the video playback area B, is 255 (serving as the grayscale value of the content displayed in the video playback area B). Therefore, the grayscale difference between pixel b and pixel c is 255, which is greater than the grayscale difference threshold, posing a certain risk of screen burn-in.

[0152] In this case, such as Figure 10 As shown, when the display time of the video playback areas in regions C and B of the outer screen 20 reaches 30 minutes, the foldable screen phone 100 can adjust the grayscale value of the background image in region C from grayscale 0 to grayscale 32. This adjusts the grayscale value of pixel c in region C from grayscale 0 to grayscale 32, reducing the grayscale difference between pixel b in region B and pixel c in region C from 255 to 223. This makes the grayscale difference between pixel b and pixel c less than the grayscale difference threshold 240, thus ensuring that the grayscale difference between the video playback area in region B and the displayed content in region C is less than the grayscale difference threshold, preventing screen burn-in at the boundary between the video playback area in region B and region C of the outer screen 20.

[0153] In this embodiment, when the electronic device detects that the grayscale difference between the display content of the first display area and the second display area on the first display screen is greater than or equal to the grayscale threshold, and the display duration of the first display area and the second display area reaches the duration threshold, the electronic device adjusts the grayscale value of the display content of at least one display area in the first display area and the second display area so that the grayscale difference between the display content of the first display area and the second display area is less than the grayscale difference threshold. This can reduce the temperature difference between the first display area and the second display area, thereby reducing the risk of screen burn-in of the first display screen and preventing screen burn-in of the first display screen of the electronic device.

[0154] Figure 17 A schematic diagram of the structure of electronic device 1000 is shown. Electronic device 1000 can be a terminal device including a display screen made of organic light-emitting materials, such as the aforementioned foldable screen device (e.g., a vertically foldable screen phone or a horizontally foldable screen phone), tablet, computer, smart wearable device (e.g., smartwatch, smart bracelet), or in-vehicle device (e.g., vehicle infotainment system).

[0156] In some embodiments, when the display screen 194 can be the outer screen of the aforementioned foldable phone, the camera can be a camera set in each cutout on the outer screen of the foldable phone.

[0157] In some embodiments, when the grayscale difference of the displayed content of two adjacent display areas on the display screen 194 is greater than or equal to the aforementioned grayscale difference threshold, and the duration of simultaneous display of the two adjacent display areas reaches the aforementioned duration threshold, the display screen 194 may adjust the grayscale value of the displayed content of at least one of the two display areas so that the grayscale difference of the two adjacent display areas is less than the grayscale difference threshold, thereby reducing the brightness difference of the two adjacent display areas, thereby reducing the temperature difference of the two adjacent display areas, and thus reducing the risk of screen burn-in of the display screen 194.

[0158] It is understood that the structures illustrated in the embodiments of this application do not constitute a specific limitation on the electronic device 1000.
