Background Art

Always on display (AOD) is a function that allows electronic devices to display various types of information around the clock. This function supports electronic devices to display pictures, clock controls, etc. when the screen is off.

The AOD function requires electronic devices to display content for a long time. Depending on the displayed content, the usage of different pixels on the screen is different. If the pixels in an area are displayed at high brightness for a long time, the degree of pixel aging in this area will be higher than that in other areas of the screen. The pixels in this area will not display bright enough, causing the aging area of the pixels on the screen to have burn-in marks when the electronic device displays other content. This phenomenon is called "screen burn-in".

Summary of the invention

The present application provides a display method and an electronic device for preventing the screen burn-in problem caused by the all-weather display function.

In a first aspect, the present application provides a display method, which can be performed by an electronic device. The method includes:

The electronic device acquires an original image. The electronic device generates a compensated image based on the original image, wherein the brightness value of each pixel in the compensated image is related to the brightness value of the corresponding pixel in the original image. The electronic device generates an N-frame compensation sequence diagram based on the original image and the compensated image, and displays the original image and the N-frame compensation sequence diagram according to preset dynamic display parameters.

In this method, the electronic device can generate a compensated image based on the original image, and then generate an N-frame compensation sequence diagram based on the original image and the compensated image. By displaying the original image and the N-frame compensation sequence diagram, the electronic device can evenly use each pixel in the screen for display, thereby preventing the burn-in problem caused by the high degree of aging of individual pixels when the same image is displayed for a long time.

In one possible design, generating a compensated image based on the original image includes: calculating the brightness value of each pixel in the compensated image based on the brightness value of each pixel in the original image and a preset brightness value; or calculating the brightness value of each pixel in the compensated image based on the brightness value of each pixel in the original image and an average brightness value of the original image; or calculating the brightness value of each pixel in the compensated image based on the brightness value of each pixel in the original image and the highest brightness value of the original image.

Through this design, the present application provides multiple methods for generating compensated images. After the compensated images generated based on the above methods are superimposed on the original image, a white or gray image can be obtained, so that the compensated images can be used to compensate for the attenuation of screen pixel brightness when the electronic device displays the original image.

In a possible design, the N-frame compensation sequence diagram includes a first compensation sequence diagram, a second compensation sequence diagram, a third compensation sequence diagram and a fourth compensation sequence diagram; the N-frame compensation sequence diagram is generated according to the original image and the compensated image, including: replacing the brightness value of the pixel unit at the first position in the original image with the brightness value of the pixel unit at the first position of the compensated image to obtain the first compensation sequence diagram, the first position is a pixel unit position whose row number and column number are both odd numbers; a pixel unit includes adjacent Y pixels, Y is a positive integer; replacing the brightness value of the pixel unit at the second position in the original image with the brightness value of the pixel unit at the second position of the compensated image The second compensation sequence diagram is obtained by replacing the brightness value of the pixel unit at the third position in the original image with the brightness value of the pixel unit at the third position of the compensated image, where the second position is the pixel unit position with an even row number and an odd column number; the third compensation sequence diagram is obtained by replacing the brightness value of the pixel unit at the third position in the original image with the brightness value of the pixel unit at the third position of the compensated image, where the third position is the pixel unit position with an even row number and a column number; the fourth compensation sequence diagram is obtained by replacing the brightness value of the pixel unit at the fourth position in the original image with the brightness value of the pixel unit at the fourth position of the compensated image, where the fourth position is the pixel unit position with an odd row number and an even column number.

Through this design, the electronic device can use the pixel unit as the processing unit, and replace the brightness values of the pixel units at the odd and even numbered positions in the original image with the brightness values of the pixel units at the corresponding positions in the compensated image, respectively, to obtain four compensation sequence diagrams. The display effect of the compensation sequence diagram will not be significantly different from that of the original image, and displaying the compensation sequence diagram can achieve the effect of balancing the usage of each pixel on the screen.

In a possible design, generating N frames of compensation sequence diagram according to the original image and the compensated image includes: The brightness value of the pixel unit in the i-th row in the original image is replaced by the brightness value of the pixel unit in the i-th row of the compensated image to obtain the i-th frame compensation sequence diagram; i is a positive integer less than N, and N is the total number of rows of pixel units in the original image; a pixel unit includes adjacent Y pixels, and Y is a positive integer.

Through this design, the electronic device can use the pixel unit as the processing unit, and replace the brightness value of each row of pixel units in the original image with the brightness value of the pixel unit at the corresponding position in the compensated image, and obtain N compensation sequence images. In each compensation sequence image, there is a row of pixel units whose brightness value is different from the original image. Therefore, the display effect of each frame of the compensation sequence image will not be significantly different from the original image, ensuring the user experience. At the same time, the electronic device displays the N frames of compensation sequence images obtained in the above manner to prevent each pixel in the screen from displaying a single image for a long time, causing screen burn-in.

In a possible design, generating N frames of compensation sequence diagrams based on the original image and the compensated image includes: replacing the brightness value of the i-th column of pixel units in the original image with the brightness value of the i-th column of pixel units in the compensated image to obtain the i-th frame of compensation sequence diagram; i is a positive integer less than N, and N is the total number of pixel columns in the original image; a pixel unit includes Y adjacent pixels, and Y is a positive integer.

Through this design, the electronic device can use the pixel unit as the processing unit, and replace the brightness value of each column of pixel units in the original image with the brightness value of the pixel unit at the corresponding position in the compensated image, and obtain N compensation sequence images. In each compensation sequence image, there is a column of pixel units whose brightness value is different from the original image, so the display effect of each frame of the compensation sequence image will not be significantly different from the original image, ensuring the user experience. At the same time, the electronic device displays the N frames of compensation sequence images obtained in the above manner to prevent each pixel in the screen from displaying a single image for a long time, causing screen burn-in.

In a possible design, generating the compensated image according to the original image includes: preprocessing the original image, and generating the compensated image according to the preprocessed original image;

Among them, the preprocessing includes at least one of the following: determining a target area in the original image whose brightness is greater than a set threshold, and reducing the brightness of the target area; reducing the brightness of the original image; dividing the original image into multiple areas, and adjusting the brightness of each area separately; setting the size of the original image according to the size of the display area, and the size of the original image after setting is larger than the size of the display area.

Through this design, the electronic device can first preprocess the original image. The burn-in risk of the preprocessed original image is already lower than that of the original image. Generating a compensated image based on the preprocessed original image can further ensure the anti-burn-in effect of the display method provided in the embodiment of the present application.

In a possible design, the original image and the N-frame compensation sequence diagram are displayed according to preset dynamic display parameters, including: calculating the total number of frames of the original image and the compensation sequence diagram displayed within a preset time length according to the preset dynamic display parameters, and calculating the number of frames P of the original image displayed within the preset time length and the number of frames Q of the compensation sequence diagram displayed within the preset time length according to a preset display ratio and the total number of frames; P and Q are positive integers; the original image and the N-frame compensation sequence diagram are displayed with the preset time length as the dynamic effect period, and P frames of original images and Q frames of compensation sequence diagram are displayed in each dynamic effect period; the Q frame compensation sequence diagram belongs to the N frame compensation sequence diagram.

Through this design, the electronic device can determine the dynamic effect cycle of the electronic device displaying the original image and N frames of compensation sequence diagram according to the preset dynamic display parameters, as well as the number of frames P of the original image displayed in each dynamic effect cycle and the number of frames Q of the compensation sequence diagram displayed. The electronic device can display P frames of original images and Q frames of compensation sequence diagrams in one dynamic effect cycle. For example, the P frames of original images and Q frames of compensation sequence diagrams displayed in one dynamic effect cycle can be cross-arranged to ensure the display effect.

In one possible design, the Q is less than or equal to the N.

Through this design, the electronic device displays a set of display sequences in each animation cycle. A set of display sequences may include P frame original images and Q frame compensation sequence diagrams. By displaying one set of display sequences (when Q is equal to N) or multiple sets of display sequences (when Q is less than N), a round of N frame compensation sequence diagram display can be completed to ensure the effect of balanced screen usage.

Optionally, Q may also be an integer greater than N, and the electronic device may cyclically display N frames of compensation sequence diagrams in a preset time length. This method may also achieve the purpose of balancing the screen pixel display brightness.

In a possible design, after calculating the number of frames P of the original image displayed within a preset time length and the number of frames Q of the compensation sequence diagram displayed within a preset time length according to the preset display ratio and the total number of frames, before displaying the original image and the N-frame compensation sequence diagram with the preset time length as the animation period, the method also includes: obtaining the screen temperature, determining the temperature coefficient according to the screen temperature; adjusting the preset display ratio according to the temperature coefficient, or adjusting Q according to the temperature coefficient.

With this design, the electronic device can determine the temperature coefficient according to the screen temperature, and adjust the preset display ratio according to the temperature coefficient. For example, when the temperature coefficient is high, the ratio of the compensation sequence diagram can be increased. Or the electronic device can adjust the number of frames of the compensation sequence diagram displayed within a preset time length according to the temperature coefficient. For example, when the temperature coefficient is high, the number of frames of the compensation sequence diagram displayed within a preset time length can be increased. In this way, To reduce the impact of high screen temperature on screen pixel aging.

In a possible design, displaying the original image and the N-frame compensation sequence diagram according to preset dynamic display parameters includes: displaying the preprocessed original image and the N-frame compensation sequence diagram according to preset dynamic display parameters.

DETAILED DESCRIPTION

In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings. Among them, in the description of the embodiments of the present application, the terms "first" and "second" are used only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

It should be understood that in the embodiments of the present application, "at least one" refers to one or more, and "plurality" refers to two or more. "And/or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and/or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character "/" generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b or c can mean: a, b, c, a and b, a and c, b and c, or a, b and c, where a, b, c can be single or plural.

Always on display (AOD) is a function that allows electronic devices to display various types of information around the clock. This function supports electronic devices to still display pictures, clock controls, etc. when the screen is off. For example, FIG1 is a schematic diagram of an electronic device with an all-weather display provided by an embodiment of the present application. Referring to FIG1, an electronic device supporting the AOD function can still display wallpapers, clock controls, etc. when the screen is off.

The display area of the screen of an electronic device is an array composed of pixels. Usually, a pixel is composed of three sub-pixels: red, green and blue. The screen resolution can reflect the clarity of the image displayed on the screen. The screen resolution refers to the number of pixels that the screen can display. For example, a screen resolution of 160*128 means that the screen can display 160 horizontal pixels and 128 vertical pixels. Under the same screen size, the higher the resolution, the finer the display effect.

The AOD function requires the electronic device to display content for a long time. Depending on the displayed content, the usage of different pixels on the screen is different. If the pixels in an area are displayed at high brightness for a long time, the degree of pixel aging in this area will be higher than that in other areas of the screen. The pixels in this area will not display enough brightness, causing the aging area of the pixels on the screen to show burn-in marks when the electronic device displays other content. The above phenomenon is called "burn-in". For example, Figure 2 is a schematic diagram of a burn-in phenomenon provided in an embodiment of the present application. Assuming that the cuffs of the character in the lock screen image shown in Figure 1 are white, when the electronic device displays the picture on the screen for a long time, the pixel position corresponding to the white area in the picture may be burn-in, as shown in Figure 2. The position of the cuffs of the character on the screen shows a burn-in mark, which causes the screen to still show the burn-in mark when displaying other content, affecting the display effect.

Based on the above problems, the present application provides a display method to prevent the burn-in problem caused by the all-weather display function. The method can be performed by an electronic device. In the display method provided in the embodiment of the present application, after the electronic device obtains the original image, it generates a compensated image based on the original image. The electronic device generates an N-frame compensation sequence diagram based on the original image and the compensated image, and displays the original image and the N-frame compensation sequence diagram according to the preset dynamic display parameters. Through the scheme, the electronic device can use each pixel in the screen evenly for display, thereby preventing the burn-in problem caused by the high degree of aging of individual pixels when the same image is displayed for a long time.

The following introduces electronic devices and embodiments for using such electronic devices. The electronic devices in the embodiments of the present application may be tablet computers, mobile phones, vehicle-mounted devices, augmented reality (AR)/virtual reality (VR) devices, notebook computers, ultra-mobile personal computers (UMPCs), netbooks, personal digital assistants (PDAs), wearable devices, etc. The embodiments of the present application do not impose any restrictions on the specific types of electronic devices.

It should be noted that the structure shown in Figures 3 and 4 is only an example of the electronic device provided in the embodiment of the present application, and cannot be used to limit the electronic device provided in the embodiment of the present application. In a specific implementation, the electronic device may have more or fewer devices or modules than those in the structure shown in Figures 3 or 4.

The display method provided in the embodiment of the present application is introduced below.

FIG5 is a flow chart of a display method provided by an embodiment of the present application. The method may be executed by an electronic device, and the electronic device may have the structure shown in FIG3 and/or FIG4. Referring to FIG5, the method includes the following steps:

S501: The electronic device obtains an original image.

In an embodiment of the present application, the electronic device supports the AOD function. When the user chooses to turn on the AOD function, the electronic device can display the lock screen wallpaper all day long. That is to say, the lock screen wallpaper can be displayed when the electronic device is in the screen-on and screen-off states. The user can set a custom image as the lock screen wallpaper, or select a system preset image as the lock screen wallpaper. The electronic device can obtain the original image that the user chooses to set as the lock screen wallpaper.

S502: The electronic device generates a compensated image according to the original image.

Optionally, the compensated image in the embodiment of the present application is an image used to compensate for the attenuation of screen pixel brightness when the electronic device displays the original image, and the brightness value of each pixel in the compensated image is related to the brightness value of the corresponding pixel in the original image. After superimposing the original image and the compensated image, a white or gray image can be obtained. For example, Figure 6 is a schematic diagram of an original image and a compensated image provided in an embodiment of the present application. Referring to Figure 6, for an area with higher brightness in the original image (such as a white area in the original image as shown in Figure 6), the brightness of the image at the same position in the compensated image is lower (such as a black area in the compensated image as shown in Figure 6). If the original image and the compensated image are superimposed, a white image can be obtained.

In the embodiment of the present application, the sum of the brightness value of the pixel in the compensated image and the brightness value of the pixel at the same position in the original image can be a preset value. The following is an introduction to several methods of generating compensated images provided in the embodiment of the present application:

Method 1: Calculate the brightness value of each pixel in the compensated image according to the brightness value of each pixel in the original image and the preset brightness value.

In an optional implementation, the electronic device may obtain the brightness value of the pixel in the original image, calculate the difference between the preset brightness value and the brightness value, and use the calculated result as the brightness value of the pixel at the same position in the compensated image. For example, taking the original image and the compensated image both in RGB format, the preset brightness value may be the maximum brightness value of a pixel (255, 255, 255), then the brightness value of the original image and the brightness value of the compensated image may satisfy the following formula:
RGB' _i =RGB(255,255,255)-RGB _i (r,g,b)

Where _RGB'i is the brightness value of the i-th pixel in the compensated image, and _RGBi (r,g,b) is the brightness value of the i-th pixel in the original image.

Method 2: Calculate the brightness value of each pixel in the compensated image according to the brightness value of each pixel in the original image and the average brightness value of the original image.

In an optional implementation, the electronic device may calculate the average brightness value of the original image, then calculate the difference between the average brightness value and the brightness value of the original image, and use the calculated result as the brightness value of the pixel at the same position of the compensated image. For example, taking the original image and the compensated image both in RGB format, the brightness value of the original image and the brightness value of the compensated image may satisfy the following formula:
RGB' _i =RGB(avgR,avgG,avgB)-RGB _i (r,g,b)

Where _RGB'i is the brightness value of the i-th pixel in the compensated image, RGB(avgR,avgG,avgB) is the average brightness value of the original image, and _RGBi (r,g,b) is the brightness value of the i-th pixel in the original image.

Method 3: Calculate the brightness value of each pixel in the compensated image according to the brightness value of each pixel in the original image and the highest brightness value of the original image.

In an optional implementation, the electronic device may determine the highest brightness value of the original image, calculate the difference between the highest brightness value and the brightness value of the original image, and use the calculated result as the brightness value of the pixel at the same position of the compensated image. For example, taking the original image and the compensated image both in RGB format, the brightness value of the original image and the brightness value of the compensated image may satisfy the following formula:
RGB' _i =RGB(maxR,maxG,maxB)-RGB _i (r,g,b)

Where _RGB'i is the brightness value of the i-th pixel in the compensated image, RGB(maxR,maxG,maxB) is the maximum brightness value of the original image, and _RGBi (r,g,b) is the brightness value of the i-th pixel in the original image.

It can be understood that the above three methods are three examples of methods for generating compensation images. Compensation images can also be generated by other methods, which are not limited in this application.

In some embodiments of the present application, before generating a compensated image based on the original image, the electronic device may preprocess the original image, and then generate the compensated image based on the preprocessed original image. The present application embodiment provides the following preprocessing, and the electronic device may perform at least one of the following preprocessing:

1. Reduce the brightness of some areas in the original image.

Optionally, the electronic device may determine a target area in the original image whose brightness is greater than a preset brightness threshold, and reduce the brightness of the target area.

2. Reduce the brightness of the original image.

Optionally, the electronic device may lower the overall brightness of the original image.

3. Divide the original image into multiple areas and adjust the brightness of each area separately.

Optionally, the electronic device may divide the original image into a plurality of regions, for example, each divided region may include a preset number of pixels. The electronic device may adjust the brightness of each divided region, for example, by reducing the brightness of a portion of an image in a region, or reducing the overall brightness of the region.

4. Pixel displacement.

Optionally, the electronic device can set the size of the original image to be larger than the size of the display area, so that when the electronic device displays the original image, it can shift the original image within the range of the display area to prevent the screen from displaying the same content for a long time and causing screen burn-in.

For example, FIG7 is a schematic diagram of a pixel shift provided in an embodiment of the present application. Referring to (a) in FIG7 , the size of the original image is larger than the image size of the display area, such as the length of the display area is 32 pixels smaller than the length of the original image, and the width of the display area is 32 pixels smaller than the width of the original image, that is, adding 16 pixels to each side of the display area can obtain the size of the original image. The electronic device can display different positions of the original image in the display area at different times. For example, referring to (b) in FIG7 , the electronic device can display the original image in different states at different times, thereby utilizing each pixel of the screen for display through pixel shift equalization.

Through the above design, the electronic device first preprocesses the original image. The burn-in risk of the preprocessed original image is already lower than that of the original image. Generating a compensated image based on the preprocessed original image can further ensure the anti-burn-in effect of the display method provided in the embodiment of the present application.

S503: The electronic device generates N frames of compensation sequence diagram according to the original image and the compensated image.

In an embodiment of the present application, to ensure the display effect, the electronic device can generate N frames of compensation sequence diagrams based on the original image and the compensated image. Each frame of the compensation sequence diagram is generated on the basis of the original image by replacing the brightness values of a part of the pixels with the brightness values of the pixels at the same position in the compensated image. Therefore, the display effect of each frame of the compensation sequence diagram will not be significantly different from that of the original image, and by displaying multiple frames of compensation sequence diagrams, the screen display brightness can be balanced to prevent different areas from aging quickly due to high brightness.

The following further introduces the various methods for generating N-frame compensation sequence diagrams provided in the embodiments of the present application.

First, the pixel units involved in the following method of generating an N-frame compensation sequence diagram are introduced. In the embodiment of the present application, the pixel unit is a pixel unit composed of multiple adjacent pixels. For example, a pixel unit may include Y pixels, where Y is a positive integer. In the embodiment of the present application, the pixel unit may be in a variety of shapes such as a rectangle, a triangle, and a diamond. The electronic device may use the pixel unit as a processing unit to perform image processing, for example, replacing the brightness value of a row of pixel units in the original image with the brightness value of a row of pixel units at the same position in the compensated image, etc.

Method 1: Odd-even position replacement method

In an optional implementation, the electronic device may replace the brightness value of the pixel unit at the first position in the original image with the compensated image The first compensation sequence diagram is obtained by calculating the brightness value of the pixel unit at the first position of the pixel unit, wherein the pixel unit is used as the processing unit, and the first position is the pixel unit position whose row number and column number are both odd numbers.

The electronic device can replace the brightness value of the pixel unit at the second position in the original image with the brightness value of the pixel unit at the second position in the compensated image to obtain a second compensation sequence diagram, wherein the second position is the pixel unit position with an even row number and an odd column number.

The electronic device can replace the brightness value of the pixel unit at the third position in the original image with the brightness value of the pixel unit at the third position in the compensated image to obtain a third compensated sequence diagram, wherein the third position is a pixel unit position with an even number of row and column numbers.

The electronic device can replace the brightness value of the pixel unit at the fourth position in the original image with the brightness value of the pixel unit at the fourth position in the compensated image to obtain a fourth compensation sequence diagram, wherein the fourth position is a pixel unit position with an odd row number and an even column number.

That is, in this manner, the value of N is 4, and the electronic device can generate four compensation sequence diagrams, namely, a first compensation sequence diagram, a second compensation sequence diagram, a third compensation sequence diagram, and a fourth compensation sequence diagram.

For example, FIG8 is a schematic diagram of the first method for generating a compensation sequence diagram provided by an embodiment of the present application. Referring to FIG8, for ease of explanation, it is assumed that the original image is a completely white image, and the compensated image is a completely black image. The electronic device may replace the brightness value of the pixel unit at the first position in the original image with the brightness value of the pixel unit at the first position of the compensated image to obtain a first compensation sequence diagram; the electronic device may replace the brightness value of the pixel unit at the second position in the original image with the brightness value of the pixel unit at the second position of the compensated image to obtain a second compensation sequence diagram; the electronic device may replace the brightness value of the pixel unit at the third position in the original image with the brightness value of the pixel unit at the third position of the compensated image to obtain a third compensation sequence diagram; the electronic device may replace the brightness value of the pixel unit at the fourth position in the original image with the brightness value of the pixel unit at the fourth position of the compensated image to obtain a fourth compensation sequence diagram.

Method 2: Scan by line

In an optional implementation, the electronic device may replace the brightness value of the pixel unit in the i-th row in the original image with the brightness value of the pixel unit in the i-th row in the compensated image to obtain the i-th frame compensation sequence diagram; i is a positive integer less than N. In this method, N is the total number of rows of pixel units in the original image.

The electronic device performs the above steps N times to obtain N frames of compensation sequence diagrams, in which the brightness value of a row of pixel units in each frame of the compensation sequence diagram is the brightness value of the pixel units at the same position in the compensated image, and the brightness values of the remaining pixel units are the brightness values of the pixel units at the same position in the original image.

FIG9 is a schematic diagram of a second method for generating a compensation sequence diagram provided by an embodiment of the present application. Referring to FIG9, for ease of explanation, assuming that the original image is a full white image, the compensated image is a full black image. The electronic device can replace the brightness values of N rows of pixel units of the original image in sequence to generate N frames of compensated images.

Method 3: Scan by column

In an optional implementation, the electronic device may replace the brightness value of the pixel unit in the i-th column of the original image with the brightness value of the pixel unit in the i-th column of the compensated image to obtain the i-th frame compensation sequence diagram; i is a positive integer less than N. In this method, N is the total number of columns of pixel units in the original image.

The electronic device performs the above steps N times to obtain N frames of compensation sequence diagrams, in which the brightness value of a column of pixel units in each frame of compensation sequence diagram is the brightness value of the pixel unit at the same position in the compensated image, and the brightness values of the remaining pixel units are the brightness values of the pixel units at the same position in the original image.

FIG10 is a schematic diagram of a third method for generating a compensation sequence diagram provided in an embodiment of the present application. Referring to FIG10 , for ease of explanation, assuming that the original image is a full white image, the compensated image is a full black image. The electronic device can replace the brightness values of N columns of pixel units of the original image in sequence to generate N frames of compensated images.

Optionally, in the above three methods, the electronic device replaces the brightness value of the pixel unit in the original image with the brightness value of the corresponding pixel unit in the compensated image, and the electronic device may replace the brightness value of each pixel included in the pixel unit in the original image with the brightness value of the corresponding pixel in the compensated image. For example, when a pixel unit includes four pixels, the electronic device may replace the brightness values of the four pixels in the original image with the brightness values of the corresponding pixels in the compensated image.

It can be understood that the above three methods are three examples of methods for generating N-frame compensation sequence diagrams. The compensation sequence diagram may also be generated in other methods, which is not limited in the present application.

S504: The electronic device displays the original image and the N-frame compensation sequence image according to preset dynamic display parameters.

In an optional implementation of the present application, the electronic device can calculate the time required to display an image within a preset time period according to preset dynamic display parameters. The total number of frames, and the number of frames of the original image displayed within the preset time length and the number of frames of the compensation sequence diagram displayed within the preset time length are determined according to the preset ratio between the display time length of the original image and the display time length of the compensation sequence diagram. Optionally, the dynamic display parameters may include a motion effect curve, a preset time length, etc. Among them, the motion effect curve can be used to indicate the speed of switching image frames when the electronic device dynamically displays the original image and multiple frames of compensation sequence diagrams. The preset time length can be used as a motion effect cycle, and the electronic device can display the original image and multiple frames of compensation sequence diagrams within one motion effect cycle.

For example, in the embodiment of the present application, the electronic device determines the number of frames P of the original image displayed within the preset time length T according to the dynamic display parameters, and the number of frames Q of the compensation sequence diagram displayed within the preset time length T, where P and Q are both positive integers.

In an optional implementation, the electronic device may combine the P-frame original image and the Q-frame compensation sequence diagram to obtain a set of display sequences, in which the P-frame original image and the Q-frame original image may be arranged crosswise. The electronic device may use a preset duration as the motion effect cycle, and display multiple frames of images in the display sequence in sequence within one motion effect cycle. Optionally, the electronic device may generate multiple groups of display sequences, and the Q-frame compensation sequence diagram in each group of display sequences is part or all of the compensation sequence diagrams in the N-frame compensation sequence diagram generated by the electronic device, that is, Q is a positive integer less than or equal to N. The electronic device displays a set of display sequences within each motion effect cycle, and a round of N-frame compensation sequence diagram display can be completed by displaying a set of display sequences (when Q is equal to N) or multiple sets of display sequences (when Q is less than N) to ensure the effect of balanced screen usage.

For example, Figure 11 is a schematic diagram of a display sequence provided in an embodiment of the present application. Referring to Figure 11, for ease of explanation, assuming that the original image is an all-white image, the compensated image is an all-black image. Assuming that the electronic device generates 10 frames of compensation sequence diagrams, and the electronic device determines to display 10 frames of original images and 5 frames of compensation sequence diagrams within a preset time length, the electronic device can generate two groups of display sequences. As shown in Figure 11, each group of display sequences generated by the electronic device includes 10 frames of original images and 5 frames of compensation sequence diagrams, and the 10 frames of original images and the 5 frames of compensation sequence diagrams are arranged crosswise, so that the display effect can be guaranteed when the electronic device displays the display sequence. After two preset time lengths, the electronic device can complete a round of display of 10 frames of compensation sequence diagrams, so that the brightness of each pixel on the screen is balanced.

In some other optional embodiments of the present application, Q can also be an integer greater than N, and the electronic device can cyclically display N frames of compensation sequence diagrams in a preset time length. This method can also achieve the purpose of balancing the screen pixel display brightness, which will not be repeated here.

It should be noted that when the electronic device performs pixel shift preprocessing on the original image, the electronic device can adjust the position of the image in the display area when displaying the original image and the N-frame compensation sequence diagram. For example, refer to the method of displaying the image in the display area shown in Figure 7, so as to utilize each pixel of the screen for display through pixel shift equalization.

Optionally, the electronic device may also display the preprocessed original image and N-frame compensation sequence diagram according to the dynamic display parameters. For specific implementation, reference may be made to the above-mentioned method for displaying the original image and N-frame compensation sequence diagram by the electronic device, and repeated parts will not be repeated.

In some embodiments of the present application, considering that the screen temperature of the electronic device may also increase the risk of screen burn-in, the electronic device may obtain the screen temperature when calculating the number of frames of the compensation sequence diagram displayed within a preset time, and determine the temperature coefficient according to the screen temperature. For example, the temperature coefficient may satisfy the following formula:
Temperature coefficient = (current screen temperature - temperature threshold) / 10

The electronic device can adjust the preset display ratio or the number of frames of the compensation sequence image displayed within the preset duration according to the temperature coefficient. For example, when the temperature coefficient is 1, the electronic device can adjust the preset display ratio so that the duration of displaying the compensation image is twice the original value, or the electronic device can adjust the number of frames of the compensation sequence image displayed within the preset duration to twice the original value. In this way, the impact of excessive screen temperature on screen pixel aging can be reduced.

Optionally, when the electronic device adjusts the preset display ratio according to the temperature coefficient, it can also adjust the preset duration. For example, when the temperature coefficient is 1, the electronic device can adjust the preset display ratio so that the duration of displaying the compensated image is twice the original value, and the electronic device can increase the value of the preset duration. In other words, as the duration of an adjusted motion effect cycle increases, the duration of displaying the original image and the duration of displaying the compensated image in a corresponding motion effect cycle will both increase, and the increase in the duration of displaying the compensated image in a motion effect cycle is greater than the increase in the duration of displaying the original image in a motion effect cycle. In this way, the dynamic display effect can be guaranteed, while increasing the duration of displaying the compensated image to reduce the impact of excessive temperature on screen pixel aging.

The embodiment of the present application also provides a display method. In this method, multiple images can be pre-set in the electronic device, and the user can select an image from the multiple images as a wallpaper. When the AOD function of the electronic device is turned on, the electronic device can normally display different areas in the image at different times according to the pre-configured display parameters. When displaying part of the area normally, the electronic device displays other areas in the image in grayscale.

For example, FIG12 is a schematic diagram of a display method provided by an embodiment of the present application. Referring to FIG12, the pattern filled with oblique lines in the figure represents grayscale display, and the pattern filled with white represents normal display. The electronic device normally displays different areas at different times, so that when the electronic device displays an image based on this method, the user can see the effect of each area lighting up in turn. This method can balance the use of various areas of the screen. Pixels are displayed to prevent screen burn-in.

In other embodiments of the present application, the electronic device can also display a "mask" on the wallpaper image set by the user when the AOD function is turned on. The mask can be a layer located on the wallpaper layer. Figure 13 is a schematic diagram of a mask display provided in an embodiment of the present application. Referring to Figure 13, the electronic device can display a mask on the wallpaper. The mask includes a transparent area and a non-transparent area. The wallpaper can be displayed through the transparent area of the mask, and the non-transparent area will block the wallpaper. The electronic device can adjust the position of the transparent area to display different areas of the wallpaper at different times, achieve balanced use of each pixel of the screen for display, and prevent screen burn-in.
