[0027] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0028] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0029] The display method and electronic device provided in the embodiments of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0030] Figure 1 It is a flow chart of a display method provided in an embodiment of the present application.

[0031] Step S102, when the signal source continuously inputs multiple frames of images, obtain the first brightness information of the Nth frame image and the second brightness information of the N-1th frame image; each frame of the multiple frames of images includes the first image data displayed on the odd lines of the display screen and the second image data displayed on the even lines of the display screen.

[0032] The signal source may be a signal source of a display screen of an electronic device, and is used to input an image according to a current signal scanning mode. Each frame of an image input by the signal source may be displayed on the display screen.

[0033] Among the multiple frames of images input by the signal source, the original image data of each frame of image includes both first image data that can be displayed on odd-numbered lines of the display screen and second image data that can be displayed on even-numbered lines of the display screen.

[0034] The multiple frames of images input by the signal source can be images with the same content of multiple frames of original image data, or can be images to be processed with different contents of multiple frames of original image data. They can also be images with both the same content of multiple frames of original image data and images to be processed with different contents of multiple frames of original image data, and so on.

[0035] For any frame, the signal source can obtain and input the frame image based on all data in the original image data of the frame image, or can obtain and input the frame image based on a portion of the original image data of the frame image. How the signal source obtains the image to be input is determined by the signal scanning method.

[0036] The signal scanning mode of the signal source may be a mode in which the signal source inputs an image. For multiple frames of images with the same or similar content, the image displayed on the display screen may be changed by changing the signal scanning mode of the signal source.

[0037] The signal scanning mode of the signal source may be an initial scanning mode, a burn-in protection scanning mode, a transition scanning mode, and so on.

[0038] The initial scanning mode may be a conventional scanning mode, for example, progressive scanning, interlaced scanning, and the like.

[0039] When the signal scanning mode of the signal source is the initial scanning mode, the content of each frame image input by the signal source can be completely consistent with the content of the original image data of the frame image, and thus, the content of the frame image displayed on the display screen can be completely consistent with the content of the original image data of the frame image.

[0040] Specifically, when the signal scanning mode of the signal source is the initial scanning mode, the signal source inputs the i-th frame image, and the original image data of the i-th frame image includes the corresponding first image data and the second image data. After receiving the i-th frame image input by the signal source, the electronic device displays the i-th frame image on the display screen, and the i-th frame image includes both the corresponding first image data and the corresponding second image data. i is any non-zero natural number.

[0041] When the display screen continues to display similar content, some areas of the display screen continue to emit light, which may cause serious loss of electronic devices used for light emission, resulting in "screen burn-in". The screen burn-in protection scanning method can be a signal scanning method provided by an embodiment of the present application that can reduce the loss of electronic devices in the display screen caused by the "screen burn-in" phenomenon.

[0042] When the signal scanning mode of the signal source is a burn-in protection scanning mode, the content of each frame image input by the signal source may be different from the content of the original image data of the frame image, and thus, the content of the frame image displayed on the display screen may be different from the content of the original image data of the frame image.

[0043] The transition scanning mode may be a signal scanning mode used to transition between the burn-in protection scanning mode and the initial scanning mode when the display screen changes from continuously displaying similar content to displaying different content.

[0044] When the signal scanning mode of the signal source is a burn-in protection scanning mode, the content of each frame image input by the signal source may be different from the content of the original image data of the frame image, and thus, the content of the frame image displayed on the display screen may be different from the content of the original image data of the frame image.

[0045] The first brightness information of the Nth frame image and the second brightness information of the N-1th frame image are obtained, wherein N is any natural number greater than 1, and the N-1th frame image may be a frame image before the Nth frame image in the multiple frames of images.

[0046] In one embodiment, the brightness information of the image can be represented by the sum of the grayscale values ​​of the pixels included in the image. The grayscale can be based on the brightness difference between the maximum brightness and the minimum brightness, and the brightness value range is divided into a plurality of value intervals, each value interval corresponds to a grayscale value of the grayscale. In multiple frames of images, each frame of the image includes the same number of pixels, and the grayscale values ​​of any two pixels can be the same or different.

[0047] Take the 8-bit grayscale value as an example. 8 = 256, then any value in the value range 0-256 can be used as the grayscale value of the pixel to represent the brightness information of the pixel. 0 can be used to represent the minimum brightness of the pixel, and 256 can be used to represent the maximum brightness of the pixel. The closer the grayscale value of the pixel is to 0, the smaller the brightness of the pixel; the closer the grayscale value of the pixel is to 256, the greater the brightness of the pixel.

[0048] The brightness information of the Nth frame image is the first brightness information, and the brightness information of the N-1th frame image is the second brightness information.

[0049] Exemplarily, the Nth frame image includes 8 pixels, and the grayscale values ​​of the 8 pixels are 10, 25, 244, 142, 242, 31, 62, and 24, respectively. Then, the first brightness information of the Nth frame image may be 10+25+244+142+242+31+62+24=780. The N-1th frame image includes 8 pixels, and the grayscale values ​​of the 8 pixels are 12, 25, 244, 142, 240, 31, 63, and 24, respectively. Then, the first brightness information of the N-1th frame image may be 12+25+244+142+240+31+63+24=781.

[0050] The brightness information of an image can also be reflected by other parameters used to characterize brightness, such as luminous intensity, luminous flux, illuminance, etc., which are not listed here one by one.

[0051] Optionally, each frame of the multiple images includes multiple partitions; obtaining the first brightness information of the Nth frame image and the second brightness information of the N-1th frame image includes: when the signal source inputs the Nth frame image, counting the brightness information of each partition of the Nth frame image to obtain the first brightness information; reading the pre-stored N-1th frame image, counting the brightness information of each partition of the N-1th frame image to obtain the second brightness information; storing the Nth frame image. Each frame image may include multiple partitions. The display content of each frame image may be different, but the partition method is the same, then each frame image includes the same number of partitions, and each partition has the same size, shape, and position in different frame images.

[0052] The brightness information of each partition in the image can be represented by the sum of the grayscale values ​​of the pixels included in each partition. The brightness information of each partition in the Nth frame image can be the first brightness information of the partition, and the brightness information of each partition in the N-1th frame image can be the second brightness information of the partition.

[0053] In the case where the signal source inputs the Nth frame image, firstly, the brightness information of each sub-area in the Nth frame image can be counted according to the grayscale values ​​of each pixel included in the Nth frame image to obtain the first brightness information of each sub-area; secondly, the pre-stored N-1th frame image can be read, and the brightness information of each sub-area in the N-1th frame image can be counted according to the grayscale values ​​of each pixel included in the N-1th frame image to obtain the second brightness information of each sub-area; thirdly, the Nth frame image can be stored to be read when the signal source inputs the N+1th frame image. The N+1th frame image can be the next frame image of the Nth frame image in the multiple frames of images.

[0054] In specific implementation, the Nth frame image can be stored in the FrameBuffer frame buffer, or the pre-stored N-1th frame image can be read from the FrameBuffer. FrameBuffer is an interface provided by the Linux system for display devices. It abstracts the display buffer, shields the underlying differences of the image hardware, and allows upper-level applications to directly read and write the display buffer in graphics mode.

[0055] Step S104: Determine brightness difference information between the Nth frame image and the N-1th frame image based on the first brightness information and the second brightness information.

[0056] By calculating the difference between the first brightness information and the second brightness information, brightness difference information between the Nth frame image and the N-1th frame image can be calculated.

[0057] For example, the first brightness information of the Nth frame image may be the sum a of the grayscale values ​​of each pixel in the 8 pixels included in the Nth frame image, and the brightness information of the N-1th frame image may be the sum b of the grayscale values ​​of each pixel in the 8 pixels included in the N-1th frame image. Then the brightness difference information between the Nth frame image and the N-1th frame image may be (ab).

[0058] When each frame image includes multiple partitions, the first brightness information and the second brightness information corresponding to the same partition are subtracted to calculate the brightness difference information of each partition between the Nth frame image and the N-1th frame image.

[0059] For example, each frame image includes 4 partitions: s1, s2, s3 and s4, each partition includes 8 pixels. The first brightness information of the partition s1 of the Nth frame image may be the sum a1 of the grayscale values ​​of each pixel in the 8 pixels included in the partition s1 of the Nth frame image; the first brightness information of the partition s2 of the Nth frame image may be the sum a2 of the grayscale values ​​of each pixel in the 8 pixels included in the partition s2 of the Nth frame image; the first brightness information of the partition s3 of the Nth frame image may be the sum a3 of the grayscale values ​​of each pixel in the 8 pixels included in the partition s3 of the Nth frame image; the first brightness information of the partition s4 of the Nth frame image may be the sum a4 of the grayscale values ​​of each pixel in the 8 pixels included in the partition s4 of the Nth frame image.

[0060] The first brightness information of partition s1 of the N-1th frame image may be the sum b1 of the grayscale values ​​of each pixel among the 8 pixels included in partition s1 in the N-1th frame image; the first brightness information of partition s2 of the Nth frame image may be the sum b2 of the grayscale values ​​of each pixel among the 8 pixels included in partition s2 in the Nth frame image; the first brightness information of partition s3 of the Nth frame image may be the sum b3 of the grayscale values ​​of each pixel among the 8 pixels included in partition s3 in the Nth frame image; the first brightness information of partition s4 of the Nth frame image may be the sum b4 of the grayscale values ​​of each pixel among the 8 pixels included in partition s4 in the Nth frame image.

[0061] Then the brightness difference information between the N-th frame image and the N-1-th frame image of partition s1 can be (a1-b1); the brightness difference information between the N-th frame image and the N-1-th frame image of partition s2 can be (a2-b2); the brightness difference information between the N-th frame image and the N-1-th frame image of partition s3 can be (a3-b3); the brightness difference information between the N-th frame image and the N-1-th frame image of partition s4 can be (a4-b4).

[0062] Below, you can combine Figure 2 Step S104 is described together. Figure 2 It is a flowchart of how to determine the brightness information difference in a display method provided in an embodiment of the present application.

[0063] like Figure 2 As shown, Frame N refers to the Nth frame image, Frame N-1 refers to the N-1th frame image, and FrameBuffer refers to the frame buffer.

[0064] Step S202: collecting statistics of first brightness information.

[0065] The first brightness information is counted for the N-th frame image.

[0066] When the Nth frame image input by the signal source is acquired, first brightness information of the Nth frame image is obtained by statistics.

[0067] Step S204: collecting statistics of second brightness information.

[0068] The N-1th frame image is read from the Frame Buffer and second brightness information is counted for the N-1th frame image.

[0069] When the Nth frame image input by the signal source is acquired, the N-1th frame image is read from the Frame Buffer and the second brightness information of the N-1th frame image is obtained by statistics.

[0070] Both step S202 and step S204 are triggered by “obtaining the Nth frame image of the signal source input” and can be executed simultaneously, or step S202 can be executed first and then step S204, or step S204 can be executed first and then step S202.

[0071] In addition, when the Nth frame image input by the signal source is obtained, the Nth frame image can also be stored in the FrameBuffer, waiting to be read when the signal source inputs the N+1th frame image.

[0072] Step S206, determining the brightness information difference value.

[0073] Brightness difference information between the Nth frame image and the N-1th frame image is determined according to the first brightness information of the Nth frame image and the second brightness information of the N-1th frame image.

[0074] For example, when the signal source inputs the first frame image, the first frame image is stored in the Frame Buffer. When the signal source inputs the second frame image, the following three operations can be performed simultaneously:

[0075] (a1) Count the brightness information of the second frame image;

[0076] (a2) Read the first frame image from the Frame Buffer and count the corresponding brightness information;

[0077] (a3) Store the second frame image in the Frame Buffer.

[0078] Furthermore, according to the brightness information of the first frame image and the brightness information of the second frame image, the brightness difference information between the second frame image and the first frame image can be determined.

[0079] When the signal source inputs the third frame image, the following three operations can be performed simultaneously:

[0080] (b1) Count the brightness information of the third frame image;

[0081] (b2) Read the second frame image from the Frame Buffer and count the corresponding brightness information;

[0082] (b3) Store the third frame image in the Frame Buffer.

[0083] Furthermore, according to the brightness information of the second frame image and the brightness information of the third frame image, the brightness difference information between the third frame image and the second frame image can be determined.

[0084] …

[0085] When the signal source inputs the Mth frame image, the following three operations can be performed simultaneously:

[0086] (c1) Counting the brightness information of the Mth frame image;

[0087] (c2) Read the M-1th frame image from the Frame Buffer and count the corresponding brightness information;

[0088] (c3) Store the Mth frame image in the Frame Buffer.

[0089] M is the number of multiple frame images, and M can be a natural number greater than 1. N is greater than 1 and less than or equal to M.

[0090] Furthermore, according to the brightness information of the M-1th frame image and the brightness information of the M-th frame image, the brightness difference information between the M-1th frame image and the M-1th frame image can be determined.

[0091] Step S106: If it is determined based on the brightness difference information that the Nth frame image is similar to the N-1th frame image, the Nth frame image is determined as the first target image.

[0092] The Nth frame image is similar to the N-1th frame image, which means that the similarity between the content of the Nth frame image and the content of the N-1th frame image is greater than or equal to a preset similarity threshold.

[0093] If the two adjacent frames of images are similar, the latter one of the two adjacent frames of images is determined to be the first target image. By determining the first target image, it is possible to quickly detect that the contents of the two adjacent frames of images are similar.

[0094] In some practical scenarios, the brightness information difference can indirectly reflect the similarity of the content of adjacent frame images. For example, when an electronic device runs a clock display application, the display screen does not involve changes in the luminous color. If the image content changes, the brightness information will definitely change.

[0095] Optionally, whether the Nth frame image is similar to the N-1th frame image is determined in the following manner: based on the first brightness information and the second brightness information, the brightness information difference between the Nth frame image and the N-1th frame image corresponding to each partition is determined; if the brightness information difference is zero, the corresponding partition is determined as the same brightness partition; it is determined whether the proportion of the number of same brightness partitions to multiple partitions is greater than or equal to a preset proportion threshold; if so, it is determined that the Nth frame image is similar to the N-1th frame image; if not, it is determined that the Nth frame image is not similar to the N-1th frame image.

[0096] Each frame image includes multiple partitions, then the first brightness information of the Nth frame image may include the first brightness information of each partition in the Nth frame image, and the second brightness information of the N-1th frame image may include the second brightness information of each partition in the N-1th frame image.

[0097] By subtracting the first brightness information of each partition in the Nth frame image from the second brightness information of the partition in the N-1th frame image, the brightness information difference value between the Nth frame image and the N-1th frame image of the partition can be calculated.

[0098] For any partition, if the brightness information difference between the Nth frame image and the N-1th frame image of the partition is zero, the corresponding partition is determined as the same brightness partition; determine whether the ratio of the number of same brightness partitions to the multiple partitions included in each frame image is greater than or equal to a preset ratio threshold; if so, determine that the Nth frame image is similar to the N-1th frame image; if not, determine that the Nth frame image is not similar to the N-1th frame image.

[0099] The following can be combined Figure 3 The partitioning of an image is explained by way of example. Figure 3 Schematic diagram of image partitioning in a display method provided in an embodiment of the present application. Figure 3 As shown, the image can be composed of image subunits with R rows and C columns. An image subunit can be a pixel or a pixel group composed of multiple pixels. The image can be pre-divided into m*n partitions, that is, the image is composed of partitions with m rows and n columns. Among them, m, n, R, C are all natural numbers greater than 0, 1≤m≤R, 1≤n≤C. Calculate the sum of the grayscale values ​​of all pixels in each partition, denoted by S 11 , S 12 , ... S mn .

[0100] like Figure 3 As shown, the S in the upper left corner 11 represents the sum of the grayscale values ​​of the pixels in the partition located in the first row and the first column, S 11 The S on the right 12 It represents the sum of the grayscale values ​​of each pixel in the partition located in the first row and the second column. mn Represents the sum of the grayscale values ​​of each pixel included in the partition located at the mth row and nth column.

[0101] The partitioning method of the Nth frame image and the N-1th frame image is as follows Figure 3In the case shown, in order to determine whether the Nth frame image is similar to the N-1th frame image, the brightness information difference between the Nth frame image and the N-1th frame image can be calculated for any one of the (m*n) partitions. If the brightness information difference between the Nth frame image and the N-1th frame image of this partition is zero, then the partition is determined to be a partition with the same brightness; determine whether the ratio of the number of partitions with the same brightness to (m*n) is greater than or equal to a preset ratio threshold, for example, 90%; if so, determine that the Nth frame image is similar to the N-1th frame image; if not, determine that the Nth frame image is not similar to the N-1th frame image.

[0102] Combination Figure 2 and Figure 3 , for example, in the Nth frame image: for the partition located at the 1st row and the 1st column, the first brightness information S of the Nth frame image 11 and the first brightness information S of the N-1th frame image 11 The difference between ' can be expressed as Δ 11 Indicates: For the partition located at the 1st row and the 2nd column, the first brightness information S of the Nth frame image 12 and the first brightness information S of the N-1th frame image 12 The difference between ' can be expressed as Δ 12 It means... for the partition located at the nth row and the mth column, the first brightness information S of the Nth frame image nm and the second brightness information S of the N-1th frame image nm The difference between ' can be expressed as Δ nm That is, the brightness information difference between the Nth frame image and the N-1th frame image includes: Δ 11 , Δ 12 , Δ 13 ……Δ nm .

[0103] Step S108, if it is detected that the signal source continuously inputs multiple frames of the first target image, and the number of the multiple frames of the first target image is greater than or equal to the first preset frame number threshold, the signal scanning mode of the signal source is subjected to a first control process, so that the display screen alternately displays the first image and the second image after a first period of time; the first image includes the first image data in the corresponding frame image input by the signal source; the second image includes the second image data in the corresponding frame image input by the signal source.

[0104] The first control process may be a switching control process for the signal scanning mode, so that the signal scanning mode is switched from the initial scanning mode to the burn-in protection scanning mode.

[0105] If it is detected that the signal source continuously inputs multiple frames of the first target image, and the number of the multiple frames of the first target image is greater than or equal to the first preset frame number threshold, it means that the image content displayed on the display screen is similar and has lasted for a period of time. In this case, the display screen has a burn-in protection requirement, and the signal scanning mode of the signal source can be subjected to a first control processing to switch the signal scanning mode from the initial scanning mode to the burn-in protection scanning mode.

[0106] If the number of continuously input multiple frames of the first target image is less than the first preset frame number threshold, it means that the duration of similar image content displayed on the display screen is short, and the image content displayed on the display screen begins to change again. In this case, there is no need for burn-in protection, and there is no need to take burn-in protection measures. The signal scanning mode of the signal source has always been the initial scanning mode.

[0107] If the signal source is not detected to continuously input multiple frames of the first target image, it means that the image content displayed on the display screen is not similar, there is no need for burn-in protection, and there is no need to take burn-in protection measures. The signal scanning mode of the signal source is always the initial scanning mode.

[0108] The first image includes first image data in the corresponding frame image input by the signal source, that is, the first image data included in the original image data of the corresponding frame image; the second image includes second image data in the corresponding frame image input by the signal source, that is, the second image data included in the original image data of the corresponding frame image. In one embodiment, after the signal scanning mode of the signal source is switched to the burn-in protection scanning mode, the time period before the signal scanning mode is switched again can be divided into two time periods: a first time period and a second time period.

[0109] In the first time period, the display screen alternately displays the third image and the fourth image. The third image includes the first image data in the corresponding frame image input by the signal source and the second image data in the corresponding frame image input by the signal source after attenuation processing. The fourth image includes the first image data in the corresponding frame image input by the signal source and the second image data in the corresponding frame image input by the signal source after attenuation processing.

[0110] The attenuated second image data in the corresponding frame image input by the signal source may be generated by attenuating the second image data in the corresponding frame image input by the signal source based on the attenuation coefficient.

[0111] The attenuation coefficient may be a numerical variable that gradually decreases to zero based on the increase of time. For example, the attenuation coefficient takes a value of 1 at the first second, a value of 0.9 at the second second, a value of 0.8 at the third second, ..., a value of 0.1 at the tenth second, a value of 0 at the eleventh second, and then maintains a value of 0 at the eleventh second.

[0112] In a specific implementation, the second image data in the corresponding frame image input by the signal source is attenuated based on the attenuation coefficient. The value of the brightness information of the second image data is multiplied by the attenuation coefficient that changes with time to obtain the value of the brightness information of the second image data after attenuation processing.

[0113] For example, in the first second, the attenuation coefficient is 1, then the value of the brightness information of the second image data after attenuation processing is equal to the product of the value of the brightness information of the second image data without attenuation processing and the attenuation coefficient "1"; in the second second, the attenuation coefficient is 0.9, then the value of the brightness information of the second image data after attenuation processing is equal to the product of the value of the brightness information of the second image data without attenuation processing and the attenuation coefficient "0.9"; in the third second, the attenuation coefficient is 0.8, then the value of the brightness information of the second image data after attenuation processing is equal to the value of the brightness information of the second image data without attenuation processing and the attenuation coefficient "0.8" ...At the 10th second, the attenuation coefficient is 0.1, then the value of the brightness information of the second image data after attenuation is equal to the product of the value of the brightness information of the second image data without attenuation and the attenuation coefficient "0.1"; at the 11th second, the attenuation coefficient is 0, then the value of the brightness information of the second image data after attenuation is equal to the product of the value of the brightness information of the second image data without attenuation and the attenuation coefficient "0", that is, the second image data after attenuation is equivalent to the non-existence of image data; after the 11th second, the value of the attenuation coefficient remains 0, that is, the second image data after attenuation is equivalent to the non-existence of image data.

[0114] In the case where the third image includes the first image data in the corresponding frame image input by the signal source and the second image data in the corresponding frame image input by the signal source after attenuation processing, as time increases, the value of the attenuation coefficient gradually decreases, and the value of the brightness information of the second image data after attenuation processing gradually decreases. Then, the value of the brightness information of the second image data after attenuation processing included in the third image gradually decreases.

[0115] Similarly, the first image data in the corresponding frame image input by the signal source that has been attenuated can be generated by attenuating the first image data in the corresponding frame image input by the signal source based on the attenuation coefficient. Please refer to the description of the second image data in the corresponding frame image input by the signal source that has been attenuated.

[0116] In the case where the fourth image includes the second image data in the corresponding frame image input by the signal source and the first image data in the corresponding frame image input by the signal source after attenuation processing, as time increases, the value of the attenuation coefficient gradually decreases, and the value of the brightness information of the first image data after attenuation processing gradually decreases. Then, the value of the brightness information of the second image data after attenuation processing included in the third image gradually decreases. Please refer to the description of the third image above.

[0117] During the second time period, the display screen alternately displays the first image and the second image.

[0118] The first duration may be the duration of the first time period, which may be determined according to parameters used in the attenuation process.

[0119] In another embodiment, after the signal scanning mode of the signal source is switched to the burn-in protection scanning mode, the time period before the signal scanning mode is switched again can be divided into three time periods: a third time period, a fourth time period and a fifth time period.

[0120] In the third time period, the display screen displays the first image data and the second image data in the corresponding frame image, that is, displays all the contents in the original image data of the corresponding frame image. The duration of the third time period can be preset to a fixed value.

[0121] During the fourth time period, the display screen alternately displays the third image and the fourth image.

[0122] During the fifth time period, the display screen alternately displays the first image and the second image.

[0123] The first duration may be the sum of the durations of the third time period and the fourth time period, and the first duration may be determined according to the parameters used in the attenuation process and the duration of the third time period.

[0124] After a first period of time after the signal scanning mode of the signal source is switched to the burn-in protection scanning mode, the odd-numbered frame images input by the signal source include the first image, and the even-numbered frame images input by the signal source include the second image; or, the even-numbered frame images input by the signal source include the first image, and the odd-numbered frame images input by the signal source include the second image, so that the display screen alternately displays the first image and the second image.

[0125] For example, the first preset frame number threshold is 10. When it is determined according to the brightness information difference that the Xth frame to the X+10th frame input by the signal source are all the first target image, the signal scanning mode of the signal source is subjected to the first control processing, and starting from the X+11th frame, the signal source inputs the image according to the burn-in protection scanning mode.

[0126] Here you can combine Figure 4The display effect of the display screen after the first duration is explained together. Figure 4 It is a schematic diagram of a display screen to which a display method is applied provided in an embodiment of the present application.

[0127] like Figure 4 As shown, in the display screen of the odd-numbered frame image 401, only the first image data in the original image data is displayed, and the second image data in the original image data is not displayed; in the display screen of the even-numbered frame image 403, only the second image data is displayed, and the first image data is not displayed. After the odd-numbered frame image 401 and the even-numbered frame image 403 are superimposed, the original image 405 can be obtained. In the display screen of the original image 405, both the first image data and the second image data are displayed.

[0128] Figure 4 The plus sign “+” 402 in FIG. 4 is used to indicate that the odd-numbered frame image 401 is superimposed on the even-numbered frame image 403. Figure 4 The equal sign “=” in is used to indicate that the visual effect of the display screen of the original image 405 is the same as the visual effect of the display screen after the odd-numbered frame image 401 and the even-numbered frame image 403 are superimposed.

[0129] Since the odd frames are adjacent to the even frames and the time interval between two adjacent frames of the signal source input is short, it is difficult for the human eye to distinguish them. Therefore, even if the odd-numbered frame image displayed on the display screen only includes half of the content of the original image data and the even-numbered frame image only includes the other half of the content of the original image data, the visual effect of the display screen seen by the human eye in this case is the same as the visual effect when each frame image displayed on the display screen includes the entire content of the original image data.

[0130] By performing a first control process on the signal scanning mode of the signal source when it is detected that the signal source continuously inputs multiple frames of the first target image and the number of the multiple frames of the first target image is greater than or equal to a first preset frame number threshold, on the one hand, the luminous time of a specific area in the display screen can be reduced, the loss of electronic devices used for luminescence in the display screen can be reduced, and the life of the electronic devices can be increased; on the other hand, the display contents of two adjacent frames are different, which can improve the problem of image afterimage; on the other hand, the visual effect of the display screen does not change significantly to the human eye under the two different signal scanning modes, thereby ensuring the user's visual experience.

[0131] Optionally, a first control process is performed on a signal scanning mode of the signal source, including: switching the signal scanning mode from an initial scanning mode to a burn-in protection scanning mode, so that the Mth frame image displayed on the display screen includes the first image data and the second attenuated image data in the corresponding frame image input by the signal source, and the M+1th frame image displayed on the display screen includes the second image data and the first attenuated image data in the corresponding frame image input by the signal source; wherein the first image attenuation data is generated based on the first image data and the attenuation coefficient in the corresponding frame image input by the signal source; the second image attenuation data is generated based on the second image data and the attenuation coefficient in the corresponding frame image input by the signal source; the attenuation coefficient is a variable that changes according to a preset attenuation rule; the preset attenuation rule is configured as: based on a preset attenuation step length, decreasing frame by frame from the highest value in the first value range to the lowest value in the first value range; the initial value of the attenuation coefficient is the highest value in the first value range; the preset attenuation step length is used to characterize the reduction amount of the attenuation coefficient between two adjacent frame images.

[0132] In one embodiment, in a first time period, the values ​​of the first attenuation image data and the second attenuation image data are not zero, so that the display screen alternately displays the third image and the fourth image; in a second time period, the values ​​of the first attenuation image data and the second attenuation image data are zero, so that the display screen alternately displays the first image and the second image.

[0133] In another embodiment, in the third time period, the value of the first attenuated image data is equal to the value of the first image data, and the value of the second attenuated image data is equal to the value of the second image data, so that the display screen displays the entire content of the original image data of the corresponding frame image. In the fourth time period, the values ​​of the first attenuated image data and the second attenuated image data are not zero, so that the display screen alternately displays the third image and the fourth image; in the fifth time period, the values ​​of the first attenuated image data and the second attenuated image data are zero, so that the display screen alternately displays the first image and the second image.

[0134] The Mth frame image may be the Mth frame image after the signal source scans in accordance with the burn-in protection mode, or may be the Mth frame image among multiple frames of images continuously input by the signal source. If the Mth frame image is the Mth frame image among multiple frames of images continuously input by the signal source, M is greater than the number of image frames input by the signal source when the signal scanning mode of the signal source is subjected to the first control processing.

[0135] For example, if the Mth frame image is the Mth frame image among multiple frames of images continuously input by the signal source, the first preset frame number threshold is L. When it is determined according to the brightness information difference that the Xth frame to the X+Lth frame input by the signal source are all the first target images, the signal scanning mode of the signal source is subjected to the first control processing, so that the display screen starts from the X+Lth frame, and the signal source inputs the image according to the burn-in protection scanning mode. M can be greater than or equal to X+L.

[0136] When M is equal to X+L, in the first time period, the values ​​of the first attenuated image data and the second attenuated image data are not zero, so that the display screen alternately displays the third image and the fourth image; in the second time period, the values ​​of the first attenuated image data and the second attenuated image data are zero, so that the display screen alternately displays the first image and the second image.

[0137] When M is greater than X+L, in the third time period, the value of the first attenuated image data is equal to the value of the first image data, and the value of the second attenuated image data is equal to the value of the second image data, so that the display screen displays the entire content of the original image data of the corresponding frame image. In the fourth time period, the values ​​of the first attenuated image data and the second attenuated image data are not zero, so that the display screen alternately displays the third image and the fourth image; in the fifth time period, the values ​​of the first attenuated image data and the second attenuated image data are zero, so that the display screen alternately displays the first image and the second image.

[0138] The duration of the third time period corresponds to the difference between M and (X+L).

[0139] The attenuation coefficient is a variable that changes according to a preset attenuation rule.

[0140] The preset attenuation rule can be configured as: based on a preset attenuation step, reducing from the highest value in the first value range to the lowest value in the first value range frame by frame; the initial value of the attenuation coefficient is the highest value in the first value range; the preset attenuation step is used to characterize the reduction amount of the attenuation coefficient between two adjacent frame images.

[0141] The preset attenuation step is used to characterize the reduction amount of the attenuation coefficient between two adjacent frame images. The two adjacent frame images here can be two adjacent even frame images, two adjacent odd frame images, or adjacent odd frame images and even frame images.

[0142] Exemplarily, the first value range may be a numerical interval [0, 1], that is, the highest value of the first value range is 1, and the lowest value is 0. Taking the preset attenuation step length used to characterize the reduction amount of the attenuation coefficient between two adjacent even-numbered frame images or odd-numbered frame images as an example, for example:

[0143] The preset attenuation step length l=0,2.

[0144] l = 1 for the Mth frame image;

[0145] l = 1 for the M+1th frame image;

[0146] l = 0.8 for the M+2th frame image;

[0147] l = 0.8 for the M+3th frame image;

[0148] l = 0.6 for the M+4th frame image;

[0149] l = 0.6 for the M+5th frame image;

[0150] l = 0.4 for the M+6th frame image;

[0151] l = 0.4 for the M+7th frame image;

[0152] l = 0.2 for the M+8th frame image;

[0153] l = 0.2 for the M+9th frame image;

[0154] l = 0 for the M+10th frame image;

[0155] l = 0 for the M+11th frame image;

[0156] l = 0 for the M+12th frame image;

[0157] …

[0158] The preset attenuation rule can also be configured as: after a preset time length, based on a preset attenuation step, it decreases frame by frame from the highest value in the first value range to the lowest value in the first value range; the initial value of the attenuation coefficient is the highest value in the first value range; the preset attenuation step is used to characterize the reduction amount of the attenuation coefficient between two adjacent frames of images.

[0159] For example, the preset duration may be a first value range or a numerical interval [0, 1], that is, the highest value of the first value range is 1 and the lowest value is 0. For example, the preset attenuation step length is used to characterize the reduction amount of the attenuation coefficient between two adjacent even-numbered frame images or odd-numbered frame images, for example:

[0160] The preset attenuation step length l=0,2.

[0161] l = 1 for the Mth frame image;

[0162] l = 1 for the M+1th frame image;

[0163] l = 0.8 for the M+2th frame image;

[0164] l = 0.8 for the M+3th frame image;

[0165] …

[0166] l = 0.2 for the M+8th frame image;

[0167] l = 0.2 for the M+9th frame image;

[0168] l = 0 for the M+10th frame image;

[0169] l = 0 for the M+11th frame image;

[0170] l = 0 for the M+12th frame image;

[0171] The l corresponding to the M+13th frame image is 0, and so on.

[0172] After determining the attenuation coefficient corresponding to each frame image, the first image data can be attenuated according to the first image data in the corresponding frame image input by the signal source and the attenuation coefficient of the corresponding frame image to obtain first image attenuation data, and the second image data can be attenuated according to the second image data in the corresponding frame image input by the signal source and the attenuation coefficient of the corresponding frame image to obtain second image attenuation data.

[0173] In a specific implementation, according to the first image data in the corresponding frame image input by the signal source and the attenuation coefficient of the corresponding frame image, the first image data is attenuated to obtain the first image attenuation data, which may be obtained by multiplying the attenuation coefficient with the first image data. According to the second image data in the corresponding frame image input by the signal source and the attenuation coefficient of the corresponding frame image, the second image data is attenuated to obtain the second image attenuation data, which may be obtained by multiplying the attenuation coefficient with the second image data.

[0174] By setting the attenuation coefficient and presetting the attenuation rule, the brightness of half of the image content can be reduced frame by frame to avoid the flickering visual effect on the display.

[0175] Optionally, the preset attenuation rule is configured as follows: after the signal source inputs a first number of frames of images in a burn-in protection scanning mode, based on a preset attenuation step, the attenuation is reduced frame by frame from the highest value in the first value range to the lowest value in the first value range.

[0176] In order to prevent the screen burn-in protection from being triggered by mistake, the preset attenuation rule of the attenuation coefficient l can also be configured as follows: the value of l remains unchanged at the preset initial value in the first Y frames, and gradually decreases according to the preset attenuation step of each frame from the Y+1 frame until it is reduced to zero and remains unchanged. By making the value of l not attenuated in the first L frames and starting to attenuate from the Y+1 frame, the brightness of half of the content in the image can be reduced frame by frame only when it is determined that the display content of the display screen is similar for a long time.

[0177] Exemplarily, the first frame number can be represented by Y, and the first value range can be a numerical interval [0, 1], that is, the highest value of the first value range is 1, and the lowest value is 0. Take the preset attenuation step length used to characterize the reduction amount of the attenuation coefficient between two adjacent even-numbered frame images or odd-numbered frame images as an example, for example:

[0178] The preset attenuation step length l=0,2.

[0179] l = 1 for the Mth frame image;

[0180] l = 1 for the M+1th frame image;

[0181] l = 1 for the M+2th frame image;

[0182] l = 1 for the M+3th frame image;

[0183] …

[0184] l = 1 for the M+Yth frame image;

[0185] l = 1 for the M+Y+1th frame image;

[0186] l = 0.8 for the M+Y+2th frame image;

[0187] l = 0.8 for the M+Y+3th frame image;

[0188] …

[0189] l = 0.2 for the M+Y+8th frame image;

[0190] l = 0.2 for the M+Y+9th frame image;

[0191] l = 0 for the M+Y+10th frame image;

[0192] l = 0 for the M+Y+11th frame image;

[0193] l = 0 for the M+Y+12th frame image;

[0194] The l corresponding to the M+Y+13th frame image is 0, and so on.

[0195] Optionally, after the first control processing is performed on the signal scanning mode of the signal source, it also includes: obtaining the third brightness information of the Lth frame image and the fourth brightness information of the L-2th frame image; based on the third brightness information and the fourth brightness information, determining the brightness difference information between the Lth frame image and the L-2th frame image; if it is determined based on the brightness difference information that the Lth frame image is not similar to the L-2th frame image, then determining the Lth frame image as the second target image; if it is detected that the signal source inputs the second target image, then performing the second control processing on the signal scanning mode, so that the display screen displays the fifth image after the second time length; the fifth image includes the original image data of the corresponding frame image input by the signal source.

[0196] For any one of the multiple partitions, the third brightness information of each odd-numbered frame image and the fourth brightness information of the previous odd-numbered frame image are counted.

[0197] Here you can combine Figure 2 and Figure 3 To illustrate, for the partition located at the 1st row and the 1st column, the difference between the third brightness information S11 of the Lth frame image and the fourth brightness information S11' of the L-2th frame image can be represented by Δ11; for the partition located at the 1st row and the 2nd column, the difference between the third brightness information S12 of the Lth frame image and the fourth brightness information S12' of the L-2th frame image can be represented by Δ12... For the partition located at the nth row and the Lth column, the difference between the third brightness information Snm of the Lth frame image and the fourth brightness information Snm' of the L-2th frame image can be represented by Δnm. Then the brightness information difference between the Lth frame image and the L-2th frame image includes: Δ11, Δ12, Δ13...Δnm.

[0198] If the brightness information difference between the L-th frame image and the L-2-th frame image of the partition is zero, the partition is determined to be a partition with the same brightness; determine whether the ratio of the number of partitions with the same brightness to (L*n) is greater than or equal to a preset ratio threshold, for example, 90%; if so, determine that the L-th frame image is similar to the L-2-th frame image; if not, determine that the L-th frame image is not similar to the L-2-th frame image.

[0199] In the case where the Lth frame image is similar to the L-2th frame image, the signal scanning mode of the signal source can continue to maintain the burn-in protection scanning mode. If it is determined based on the brightness difference information that the Lth frame image is not similar to the L-2th frame image, the Lth frame image is determined as the second target image. If it is detected that the signal source inputs the second target image, it means that the display content of the display screen begins to change, and it is necessary to exit the burn-in protection as soon as possible.

[0200] If it is detected that the signal source inputs the second target image, the signal scanning mode is subjected to a second control process so that the display screen displays a fifth image after the second duration; the fifth image includes the original image data of the corresponding frame image input by the signal source.

[0201] First, for any one of the (m*n) partitions, calculate the brightness information difference between the N-th frame image and the N-1-th frame image. If the brightness information difference between the N-th frame image and the N-1-th frame image of the partition is zero, then the partition is determined as the same brightness partition; determine whether the ratio of the number of the same brightness partitions to (m*n) is greater than or equal to a preset ratio threshold, for example, 90%; if so, determine that the N-th frame image is similar to the N-1-th frame image; if not, determine that the N-th frame image is not similar to the N-1-th frame image.

[0202] The third brightness information difference between Figure 2 and Figure 3 , exemplarily, the second feature information of the Mth frame image includes:

[0203] Here you can combine Figure 5 It is described together how to trigger the second control process. Figure 5 It is a flowchart of how to trigger the second control processing in a display method provided in an embodiment of the present application.

[0204] like Figure 5 As shown, Frame M refers to the Mth frame image. M is any natural number greater than or equal to 3. FrameM-2 refers to the M-2th frame image.

[0205] Step S502, determining whether it is an odd frame.

[0206] Determine whether the Mth frame image belongs to an odd frame.

[0207] If yes, execute step S504, if no, execute step S508.

[0208] Step S504: collecting statistics of third brightness information.

[0209] For the odd-numbered frame image, third brightness information is counted.

[0210] Step S506, collecting statistics of fourth brightness information.

[0211] Read the M-2th frame image from the Frame Buffer corresponding to the odd-numbered frame image, and count the corresponding four-light brightness information.

[0212] Step S508: Count the third brightness information.

[0213] For the even-numbered frame image, third brightness information is counted.

[0214] Step S510: collecting statistics of fourth brightness information.

[0215] Read the M-2th frame image from the Frame Buffer corresponding to the even-numbered frame image, and count the corresponding four-light brightness information.

[0216] Step S512: Detect a second target image.

[0217] If it is detected that the signal source inputs the second target image, it is determined to exit the burn-in protection and perform the second control processing on the signal scanning mode.

[0218] The second control processing is performed on the signal scanning mode so that the display screen displays the fifth image after the second time period, which may be to switch the signal scanning mode so that within the time range of the second time period, the signal scanning mode is a transition scanning mode, and after the second time period, the signal scanning mode is restored to the initial scanning mode. The second time period can be preset.

[0219] Optionally, a second control processing is performed on the signal scanning mode, including: performing state switching transition processing on the signal scanning mode, so that the Kth frame image displayed on the display screen includes the first image data and the second restored image data in the corresponding frame image input by the signal source, and the K+1th frame image displayed on the display screen includes the second image data and the first restored image data in the corresponding frame image input by the signal source; wherein the first restored image data is generated based on the first image data and the attenuation recovery coefficient in the corresponding frame image input by the signal source; the second restored image data is generated based on the second image data and the attenuation recovery coefficient in the corresponding frame image input by the signal source; the attenuation recovery coefficient is a variable that changes according to a preset attenuation recovery rule; the preset attenuation recovery rule is configured as: based on a preset recovery step length, a variable that increases frame by frame from the lowest value in the second value range to the highest value in the second value range; the preset recovery step length is used to characterize the increase in the attenuation recovery coefficient between two adjacent frame images.

[0220] The signal scanning mode is subjected to state switching transition processing, which may be to switch the signal scanning mode from the burn-in protection scanning mode to the transition scanning mode within a second time period, and to switch the signal scanning mode from the transition scanning mode to the initial scanning mode after the second time period.

[0221] The attenuation recovery coefficient is a variable that changes according to a preset attenuation recovery rule. The preset attenuation recovery rule is configured as: based on a preset recovery step length, a variable that increases frame by frame from the lowest value in the second value range to the highest value in the second value range; the preset recovery step length is used to characterize the increase in the attenuation recovery coefficient between two adjacent frames of images.

[0222] Exemplarily, the second value range may be a numerical interval [0, 1], that is, the highest value of the first value range is 1, and the lowest value is 0. For example:

[0223] The default recovery step size b=0,2.

[0224] b corresponding to the Kth frame image = 0;

[0225] b = 0.2 for the K+1th frame image;

[0226] b = 0.4 for the K+2th frame image;

[0227] b = 0.6 for the K+3th frame image;

In the above example, the signal scanning mode may be regarded as switching from the transition scanning mode to the initial scanning mode from the K+6th frame. The second duration may be determined by the number of frames in which the attenuation recovery coefficient increases frame by frame from the lowest value in the second value range to the highest value in the second value range.

[0235] By setting the restoration coefficient, you can avoid screen flickering and quickly restore the signal source's signal scanning mode to the initial scanning mode, making the image displayed on the display screen visually stable and continuous, ensuring user experience.

Through the embodiments of the present application, on the one hand, if it is determined that the two adjacent frames of images are similar based on the brightness difference information of the two adjacent frames of images, the latter frame of image is determined as the first target image. If it is detected that the signal source continuously inputs multiple frames of the first target image, and the number of the multiple frames of the first target image is greater than or equal to the preset frame number threshold, it means that the display screen displays similar content for a long time. By alternating the first image data of the odd rows and the second image data of the even rows on the display screen, it can not only ensure that the overall visual effect of the display screen is not affected, but also reduce the luminous time of the display electronic devices of the odd rows of the display screen by half, and reduce the luminous time of the display electronic devices of the even rows by half, thereby reducing the loss of the display electronic devices.
