[0002] The screens of current electronic devices rely on the light-emitting diodes (LEDs) within each pixel to display images. In practice, it has been found that when the same pixel on the screen operates at high brightness for extended periods, the LEDs age faster, leading to a decrease in luminous efficiency, resulting in brightness or color variations, and ultimately, image retention on the screen, commonly known as screen burn-in.

[0030] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0031] It should be noted that the terms "first," "second," "third," and "fourth" in the specification and claims of this application are used to distinguish different objects rather than to describe a specific order. The terms "including" and "having," as well as any variations thereof, in the embodiments of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units that are not explicitly listed or are inherent to these processes, methods, products, or apparatuses.

[0032] The embodiments of the present application disclose a screen compensation method and device, an electronic device, and a computer-readable storage medium, which can perform display parameter compensation processing with different compensation accuracies on different screens in a screen, so as to reduce brightness or color differences caused by screen burn-in, thereby improving the screen's picture display effect.

[0033] The technical solution of this application will be described in detail below with reference to specific embodiments.

[0034] In order to more clearly introduce the screen compensation method disclosed in the embodiment of the present application, the "burn-in phenomenon" and the screen compensation method in the related art are first introduced.

[0035] During long-term use, the screens of current electronic devices may experience "burn-in" due to the material properties of the screen. For example, OLED (Organic Light-Emitting Diode) screens are made of organic compounds that emit light on their own. Since each pixel emits light independently and relies on the organic material to emit light under current drive, when the same pixel works at high brightness for a long time, the organic material will accelerate aging due to continuous light emission, which will lead to a decrease in luminous efficiency, resulting in brightness or color differences, and ultimately produce afterimages, commonly known as burn-in.

[0036] See also Figure 1 , Figure 1 Schematic diagram of a screen burn-in phenomenon disclosed in an embodiment of the present application. Icons displayed in the right edge region 104 of the short video page 102 are prone to screen burn-in. Even if the electronic device closes the short video page 102, the icons displayed in the right edge region 104 will leave residual images on the screen, which will affect the display of other content on the screen and affect the user experience.

[0037] Based on this, a screen aging model can be established to monitor the degree of screen aging, and then the brightness of the burned-in area can be compensated accordingly according to the degree of aging to alleviate the burn-in phenomenon.

[0038] For example, see Figure 2, Figure 2 This is a schematic diagram of an embodiment of the present application that discloses compensation through a screen aging model. Among them, since different models of screens differ in material usage and layout, the aging speeds of different screens may also be different. Therefore, corresponding screen aging models 202 can be established for different screens. Optionally, the operating parameters of the screen can be collected, including but not limited to: display frame rate, screen brightness, display content and one or more of the device temperature of the electronic device corresponding to the screen, which are not limited here. These operating parameters reflect the degree of aging of the screen to a certain extent. For example, as the degree of aging increases, the screen brightness will decrease. The degree of aging of the screen can be inferred based on the degree of decrease in screen brightness.

[0039] The screen operating parameters can then be input into the screen aging model 202 to calculate the degree of screen aging; and brightness compensation can be performed on the burned-in area of ​​the screen 204 based on the degree of screen aging output by the screen aging model 202 and the display content of the screen.

[0040] It should be noted that areas of the screen that operate at high brightness for a long time are prone to screen burn-in, such as Figure 1 When the displayed content is the short video page 102, the burn-in area is the right edge area 104. The burn-in area can be determined according to the displayed content, and then the burn-in area can be compensated, thereby reducing the compensation steps and reducing power consumption.

[0041] The embodiments of the present application disclose a screen compensation method that can be applied to various electronic devices, including: portable electronic devices such as mobile phones and tablets, wearable devices such as smart watches and smart bracelets, or desktop devices such as desktop computers and televisions, without limitation here.

[0042] Optionally, the electronic device can determine a first screen area and a second screen area in the screen, and the probability of burn-in in the first screen area is greater than the probability of burn-in in the second screen area; then the electronic device can compensate for the display parameters of the first screen area that is prone to burn-in by using a first compensation method with higher compensation accuracy to improve the compensation effect; in addition, in addition to compensating for the first screen area that is prone to burn-in, the electronic device can also compensate for the display parameters of the second screen area that is less likely to burn-in by using a second compensation method with lower compensation accuracy, thereby avoiding or eliminating the negative impact of the burn-in phenomenon as much as possible, improving the compensation effect, and thus improving the screen display effect; in addition, the second compensation method with low compensation accuracy has lower power consumption, so using the second compensation method to compensate for the second screen area can also save compensation power consumption.

[0043] Based on this, the screen compensation method and device, electronic device, and computer-readable storage medium disclosed in the embodiments of the present application are introduced below.

[0044] See also Figure 3 , Figure 3 This is a flow chart of a screen compensation method disclosed in an embodiment of the present application. Optionally, the method can be applied to the above-mentioned electronic device or other execution entities, which are not limited here. Optionally, the method can include the following steps:

[0045] 302. Determine a first screen area and a second screen area on the screen, wherein a probability of screen burn-in occurring in the first screen area is greater than a probability of screen burn-in occurring in the second screen area.

[0046] In the embodiment of the present application, the probability of screen burn-in in the first screen area is greater than that in the second screen area, indicating that the first screen area is more prone to screen burn-in. Figure 1 , Figure 1 In the short video page 102, the area of ​​the right edge area 104 used to display icons can be the first screen area, and other areas except the right edge area 104 can be the second screen area, which is not limited here.

[0047] In other optional embodiments, the first screen area may also be an area of ​​the screen where the brightness is greater than a brightness threshold and the duration is greater than a second duration threshold. The brightness threshold and the second duration threshold can be set by the developer based on extensive development experience and are not limited here.

[0048] For example, see Figure 4 , Figure 4 This is a schematic diagram of a first screen area and a second screen area disclosed in an embodiment of the present application.

[0049] The top edge area is prone to screen burn-in due to the long-term display of the taskbar; the right edge area is also prone to screen burn-in due to the display of function icons; and some operating systems display function controls or other fixed icons at the bottom of the screen, making the bottom edge area also prone to screen burn-in. Optionally, the first screen area 402 of the screen may include: the top edge area, the right edge area, and portions of the bottom edge area, etc., without limitation herein.

[0050] Optionally, part or all of other areas of the screen except the first screen area 402 may be the second screen area 404 .

[0051] In an embodiment of the present application, the electronic device may determine a first screen area on the screen based on one or more of the screen's operating parameters, user usage behavior data, and information about applications installed on the electronic device, and may determine all or part of the remaining area on the screen other than the first screen area as a second screen area. Optionally, the operating parameters may include the display frame rate, screen brightness, displayed content, and the device temperature of the electronic device corresponding to the screen, as described above, and are not limited here.

[0052] In an optional embodiment, user usage behavior data may include: commonly used applications, which may include applications in the electronic device whose total historical usage time is greater than or equal to a third time threshold. The third time threshold can be set by the developer based on a lot of development experience and is not limited here.

[0053] Optionally, the electronic device may determine frequently used applications based on user usage behavior data, and determine the burn-in area corresponding to the frequently used applications as the first screen area, and determine all or part of the screen area other than the first screen area as the second screen area. For example, if the frequently used application is a short video application, the corresponding burn-in area is the area on the right edge used to display icons, which is not limited here.

[0054] In other optional embodiments, user usage behavior data may include: the display area of ​​functional controls. Functional controls may include movable controls that can move on the screen in response to user movement operations. Optionally, movable controls may include, but are not limited to, assistive touch controls, floating windows, etc., which are not limited here.

[0055] It is understandable that areas where function controls are displayed for long periods of time are also prone to screen burn-in due to the prolonged illumination. Due to different user behavior habits, different users may place movable function controls in different locations on the screen for long periods of time. For example, for auxiliary touch controls, some users are accustomed to placing them in the upper right corner of the screen, while others are accustomed to placing them in the lower right corner of the screen. This results in different areas of the screen displaying function controls for different users, and therefore different areas prone to screen burn-in.

[0056] In this regard, the electronic device can determine the display area of ​​the function control based on the user's usage behavior data; then determine the first screen area on the screen based on the display area of ​​the function control, and determine all or part of the other areas on the screen except the first screen area as the second screen area.

[0057] As previously described, different applications may correspond to corresponding burn-in areas. Optionally, the electronic device may determine the burn-in areas corresponding to the respective applications based on information about the applications installed on the electronic device, and determine the burn-in areas corresponding to the respective applications as the first screen area, and determine all or part of the other areas of the screen other than the first screen area as the second screen area.

[0058] In an optional implementation, the electronic device may determine the central area of ​​the screen as the second screen area, and determine all or part of the remaining area outside the second screen area as the first screen area. It is understood that the central area of ​​the screen is typically used to display dynamic content and does not emit high-intensity light for a long time, so the probability of screen burn-in is low. Therefore, the central area of ​​the screen can be determined as the second screen area.

[0059] In other optional embodiments, the electronic device may determine the edge area of ​​the screen as the first screen area, and determine all or part of the other areas of the screen other than the first screen area as the second screen area. It is understood that the edge area of ​​the screen is generally used to display fixed icons and / or controls. These icons and / or controls usually emit high-intensity light for a long time, and the probability of screen burn-in is high. Therefore, the edge area of ​​the screen can be determined as the first screen area.

[0060] In some further optional embodiments, the first screen area and / or the second screen area may be determined based on an input area designation instruction, and the area designation instruction may be input by a user, which is not limited herein.

[0061] By implementing the above method, the user can determine the first screen area and / or the second screen area according to usage requirements, thereby improving the controllability of the method and further improving the user experience.

[0062] 304. Compensate the display parameters of the first screen area using a first compensation method, and compensate the display parameters of the second screen area using a second compensation method. The compensation accuracy corresponding to the first compensation method is greater than the compensation accuracy corresponding to the second compensation method.

[0063] The higher the compensation accuracy, the smaller the number of pixels in the minimum compensation unit corresponding to the compensation process.

[0064] In the embodiments of the present application, display parameters may include brightness parameters, grayscale parameters, contrast, etc., which are not limited here. Grayscale refers to the brightness level relationship between the darkest black and the brightest white of the display. Adjusting the grayscale can also eliminate the impact of screen burn-in on the display to a certain extent.

[0065] The compensation process may include adjusting display parameters, which include but are not limited to increasing display parameters (eg, increasing brightness), decreasing display parameters, etc., which are not limited here.

[0066] In the embodiments of the present application, the minimum compensation unit refers to the screen block that is counted and compensated during each compensation. For example, the minimum compensation unit may include an 8*8 pixel screen block. During compensation, the compensation value required for this 8*8 pixel screen block can be counted, and the 8*8 pixel screen block can be compensated according to the compensation value. The minimum compensation unit can also be a 1*1 pixel screen block, a 3*3 pixel screen block, etc., which are not limited here.

[0067] It is understandable that the smaller the number of pixels in the minimum compensation unit corresponding to the compensation process, the higher the compensation accuracy; therefore, the compensation effect of sequentially performing targeted counting and compensation on a 1*1 pixel screen block is better than the compensation effect of sequentially performing targeted counting and compensation on an entire 8*8 pixel screen block. In this embodiment of the present application, the number of pixels in the minimum compensation unit corresponding to the first compensation method is smaller than the number of pixels in the minimum compensation unit corresponding to the second compensation method, thereby achieving higher compensation accuracy for the first compensation method.

[0068] In the embodiment of the present application, the electronic device can simultaneously compensate the display parameters of the first screen area using the first compensation method and the display parameters of the second screen area using the second compensation method. Alternatively, the display parameters of the first screen area can be compensated using the first compensation method and the display parameters of the second screen area can be compensated using the second compensation method, respectively. This is not limited to the above.

[0069] In an optional embodiment, the electronic device may perform compensation processing on the display parameters of the first screen area according to the first compensation method through the first processor;

[0070] The display parameters of the second screen area are compensated by the second processor according to the second compensation method.

[0071] By implementing the above method, the electronic device can execute the first compensation method and the second compensation method through different processors, thereby avoiding mutual interference between the two compensation methods and improving the compensation effect; in addition, the first compensation method and the second compensation method can be executed in parallel through two processors, thereby improving the compensation efficiency.

[0072] Optionally, the operating performance of the first processor may be better than that of the second processor, thereby improving the compensation effect on the first screen area that is more prone to screen burn-in and minimizing the impact of screen burn-in on the screen display.

[0073] In an optional embodiment, the second processor may include a display driver integrated circuit (DDIC). Optionally, the second processor is limited by the upper limit of memory capacity and adopts block downsampling, typically using each 8*8 pixel point as a screen block for statistics and compensation, to achieve the purpose of reducing the amount of data. Although this method may reduce compensation accuracy, it has lower power consumption, which can reduce the power consumption of the electronic device.

[0074] The first processor may include an application processor chip (AP). Optionally, the first processor can reuse memory (e.g., DDR double-bit rate memory and / or Flash) to support higher compensation accuracy, enabling statistics and compensation for 1x1 pixel screen blocks. However, the first processor needs to read compensation content for each frame during compensation, which increases DDR read bandwidth and power consumption.

[0075] By implementing the above method, the electronic device can use higher compensation accuracy for the first screen area that is prone to burn-in to improve the compensation effect; and for the second screen area that is not prone to burn-in, a compensation method with lower power consumption can be used, thereby reducing the power consumption of the electronic device and improving the flexibility of the method.

[0076] In an optional embodiment, the power consumption corresponding to the second compensation method may be lower than the power consumption corresponding to the first compensation method.

[0077] It is understandable that the area of ​​the second screen area in the screen where burn-in is not likely to occur is usually larger than the area of ​​the first screen area where burn-in is likely to occur. By implementing the above method, for the second screen area with a larger area, a second compensation method with lower power consumption can be used for compensation while ensuring the compensation effect as much as possible, thereby saving compensation power consumption and reducing the power consumption of the electronic device.

[0078] By implementing the methods disclosed in the above embodiments, it is possible to determine the first screen area and the second screen area of ​​the screen, and the probability of burn-in occurring in the first screen area is greater than the probability of burn-in occurring in the second screen area. Therefore, the display parameters of the first screen area prone to burn-in can be compensated using a first compensation method with higher compensation accuracy to improve the compensation effect. Furthermore, in the embodiments of the present application, in addition to compensating for the first screen area prone to burn-in, the display parameters of the second screen area less prone to burn-in can also be compensated using a second compensation method with lower compensation accuracy, thereby minimizing the negative impact of burn-in and improving the screen display quality.

[0079] Furthermore, a higher compensation accuracy can be used for the first screen area that is prone to burn-in to improve the compensation effect; while a compensation method with lower power consumption can be used for the second screen area that is not prone to burn-in, thereby reducing the power consumption of the electronic device and improving the flexibility of the method; and, for the second screen area with a larger area, a second compensation method with lower power consumption can be used for compensation while ensuring the compensation effect as much as possible, thereby saving compensation power consumption and reducing the power consumption of the electronic device.

[0080] See also Figure 5 , Figure 5 This is a flow chart of another screen compensation method disclosed in an embodiment of the present application. Optionally, the method can be applied to the above-mentioned electronic device or other execution entities, which are not limited here. Optionally, the method can include the following steps:

[0081] 502. Obtain historical usage information corresponding to the screen, and determine a first screen area and a second screen area on the screen based on the historical usage information; wherein a probability of screen burn-in occurring in the first screen area is greater than a probability of screen burn-in occurring in the second screen area.

[0082] In an embodiment of the present application, historical usage information may include: the historical usage time of the screen, the historical usage time corresponding to one or more second applications in the electronic device corresponding to the screen; and the user's historical usage behavior data, etc., which are not limited here.

[0083] By implementing the above method, the electronic device can determine the first screen area that is prone to screen burn-in and the second screen area that is not prone to screen burn-in based on the historical information corresponding to the screen, so that the determined first screen area and second screen area better match the actual usage of the screen, thereby improving the accuracy of the determined first screen area and second screen area.

[0084] As an optional implementation, the electronic device may obtain screen burn-in data, wherein the screen burn-in data may include: application identifiers of multiple first application programs, and corresponding screen burn-in areas of each first application program.

[0085] The application identifier is information used to identify and distinguish different applications. The application identifier may include: the name of the application, the icon of the application, the number of the application, etc., which are not limited here.

[0086] Optionally, the plurality of first applications may be applications having a probability of screen burn-in greater than or equal to a first probability threshold, wherein the first probability threshold may be set by a developer based on a large amount of development experience and is not limited here.

[0087] Optionally, the burn-in data may be determined based on after-sales repair data, which may be data collected during after-sales repair of a screen or electronic device, and is not limited thereto. In other optional embodiments, the burn-in data may also be obtained based on statistics of screen burn-in conditions of multiple electronic devices, and is not limited thereto.

[0088] Optionally, the burn-in area corresponding to the first application may be an area on the screen where the probability of burn-in occurring when the first application is running is greater than a second probability threshold, that is, the burn-in area corresponding to the first application is an area on the screen where burn-in is prone to occurring when the first application is running.

[0089] For example, the first application may include a short video application, a music application, etc. The burn-in area corresponding to the short video application may include the right edge of the screen; the burn-in area corresponding to the music application may include the area on the screen displaying the music playback controls, which are not limited here.

[0090] Furthermore, the electronic device may determine a first screen area and a second screen area on the screen according to historical usage information and burn-in data.

[0091] By implementing the above method, the electronic device can combine the historical usage data of the screen and the burn-in data collected during maintenance and after-sales service to determine the first screen area and the second screen area on the screen, so that the determination of the first screen area and the second screen area is more in line with the common burn-in situation, thereby improving the accuracy of the determined first screen area and the second screen area.

[0092] In an optional embodiment, the historical usage information may include: one or more second applications in the electronic device corresponding to the screen, and their corresponding historical usage durations.

[0093] Optionally, the electronic device may match the application identifiers corresponding to each second application in the historical usage information with the application identifiers corresponding to multiple first applications in the burn-in data to obtain one or more target second applications in the burn-in data;

[0094] Then, a target second application program with a historical usage duration greater than or equal to the first duration threshold is determined as the target application program, and a first screen area and a second screen area are determined on the screen according to the burn-in area corresponding to the target application program.

[0095] It is understandable that the electronic device can monitor the historical usage duration of one or more second applications installed on it to obtain historical usage information. In general, the number of second applications installed in the electronic device is less than the number of first applications included in the burn-in data. For this reason, the electronic device can first determine one or more target second applications present in the burn-in data from the burn-in data. For example, assuming that the first application in the burn-in data may include: application a, application b, and application c; and the second application installed by the electronic device includes: application a and application b, then application a and application b can be determined as target second applications.

[0096] It is understandable that if the target second application is only running for a short time, it will not cause screen burn-in, as burn-in is usually caused by long-term, high-intensity light emission. In this regard, the electronic device can determine the target second application with a historical usage time greater than or equal to the first time threshold as the target application, that is, the target application is an application that is likely to cause screen burn-in.

[0097] Optionally, the first duration threshold may be set by developers based on extensive development experience, and typical values ​​may include three months, six months, or one year, etc., which are not limited here.

[0098] Furthermore, the electronic device can determine the burn-in area corresponding to the target application based on the burn-in area recorded in the burn-in data, and then determine the first screen area of ​​the screen based on the burn-in area corresponding to the target application, and determine part or all of the other areas of the screen except the first screen area as the second screen area.

[0099] By implementing the above method, the electronic device can combine the collected burn-in data to determine the first screen area and the second screen area on the screen, so that the determination of the first screen area and the second screen area is more consistent with the common burn-in situation, thereby improving the accuracy of the determined first screen area and the second screen area.

[0100] In an optional embodiment, the electronic device can obtain the current display direction of the screen, and determine a first screen area on the screen based on the burn-in area corresponding to the target application and the current display direction of the screen; and determine part or all of the other areas on the screen except the first screen area as the second screen area.

[0101] For example, see Figure 6 , Figure 66 is a schematic diagram of determining a first screen area disclosed in an embodiment of the present application. Optionally, the burn-in area in the target application may be the "area displaying the share icon 602." However, the display position of the "share icon 602" differs when the electronic device 604 is in "landscape orientation" and "portrait orientation," and the position of the burn-in area on the screen also differs accordingly.

[0102] By implementing the above method, the electronic device can determine the first screen area on the screen according to the burn-in area corresponding to the target application and the current display direction of the screen, so as to improve the accuracy of the determined first screen area and second screen area.

[0103] 504.
