[0047] Image sticking is a common problem in display technology, especially in display devices such as OLEDs. When the image transitions from low grayscale to high grayscale, the brightness cannot change quickly, resulting in image sticking when the image scrolls, which affects the display effect. To compensate for this phenomenon, an effective method is to compare the input values ​​of the pixels in the current frame with those in the previous frame, calculate the difference, and adjust the pixel values ​​by looking up a compensation table. This method requires storing the data of the previous frame. To reduce the size of the memory, a compression algorithm is usually used to compress the stored data. However, since the compressed lengths of the two frames of data may be inconsistent, it is impossible to store the compressed data of the current frame in the same memory while decompressing the previous frame data. To solve this problem, two memories are usually required, one for storing the previous frame data and the other for storing the current frame data. Although this ensures smooth alternating storage and decompression of data, it will increase the memory area. Therefore, the present application provides a display data compensation method that can not only improve the image sticking problem existing in the dynamic display process of the image, but also reduce the storage space required to store the display data.

[0048] Figure 1 This is a flow chart of a display data compensation method provided in an embodiment of the present application. The display data compensation method can be applied to the display device provided in an embodiment of the present application. Figure 1 As shown, the display data compensation method provided in this embodiment specifically includes the following steps:

[0049] Step S110: Classify and mark the display images into high dynamic scene images and low dynamic scene images according to the application scenarios of the display images.

[0050] Specifically, during the use of currently commonly used display devices, such as mobile phones and tablets, the application scenarios can be divided into high-dynamic scenes and low-dynamic scenes according to the frame rate requirements and the degree of picture changes. High-dynamic scene pictures include display pictures in game scenes and audio and video playback scenes. The content of the picture is updated frequently, there are more dynamic parts in the picture and fewer static elements. A high frame rate is required to maintain the smoothness and real-time performance of the picture. Due to the high frame rate, the pixel brightness changes quickly, so the control requirements for the ghosting phenomenon are relatively low. Low-dynamic scene pictures include display pictures in text reading scenes and web browsing scenes. The content of the picture is updated infrequently, there are more static parts in the picture and fewer dynamic elements. Due to the slow picture changes and low frame rate, low-dynamic scene pictures are more likely to have ghosting when switching. Based on this, the display data compensation method provided by the present application classifies and marks the display picture according to the application scenario of the display picture before display compensation is performed on the pre-displayed image, and adopts different compression compensation strategies according to the type of mark to meet the performance requirements and user experience in different application scenarios, which can more effectively allocate resources and improve the overall performance and efficiency of the display device.

[0051] Step S120: When the display picture belongs to a high dynamic scene picture, display compensation is performed on the display data marked as the high dynamic scene picture according to a preset first compression compensation strategy.

[0052] Specifically, high-dynamic-motion scenes typically include multiple frames and require a relatively high frame rate. In one embodiment, display compensation for display data marked as high-dynamic-motion scenes based on a preset first compression compensation strategy includes: decompressing the stored data of the previous frame of image in a first storage area to obtain the previous frame of display data; performing display compensation on the current frame of display data based on the previous frame of display data using a block-averaged data compression method; and dynamically compressing the compensated current frame of display data and storing it in a second storage area.

[0053] Specifically, since the content of high-dynamic scene images is updated quickly, the control requirements for the afterimage phenomenon are relatively low. Therefore, when compressing and storing the display data of the previous frame image and the current frame image, the image can be divided into multiple pixel blocks first, and the average value of all pixel values ​​in each pixel block is calculated. Then, dynamic compression is performed based on the pixel average value of the pixel block. In an embodiment of the present application, the first storage area and the second storage area can be two different storage areas divided in the same storage space, one storage area is used to store the display data of the previous frame image after dynamic compression, and the other storage area is used to store the display data of the current frame image after dynamic compression. Since the block averaging data compression method is also used before dynamic compression, even during dynamic compression, in order to deal with the problem of inconsistent lengths of the two frames of data, two storage areas are required to store the display data of the previous frame image and the display data of the current frame image separately, which can also save a lot of storage space.

[0054] In one embodiment, if Figure 2 As shown, based on the block average compression data method, the current frame display data is displayed and compensated according to the previous frame display data, specifically including:

[0055] Step S121: Divide the current frame image and the previous frame image into a plurality of pixel blocks of fixed size.

[0056] Specifically, after division, each pixel block in the current frame image and each pixel block in the previous frame image correspond to the same area on the display panel, and each pixel block may include multiple pixels.

[0057] Step S122: calculating the first grayscale average value of each pixel block in the current frame image according to the current frame display data, and calculating the second grayscale average value of the corresponding pixel block in the previous frame image according to the previous frame display data.

[0058] Step S123: determining display compensation data for each pixel block in the current frame image according to the grayscale difference between the first grayscale average value and the second grayscale average value.

[0059] Step S124: performing display compensation on the current frame display data according to the display compensation data of each pixel block.

[0060] Specifically, when display compensation is performed on the current frame display data based on the previous frame display data, since the previous frame display data was stored using a block average data compression method, the grayscale difference between the grayscale average value of each pixel block in the previous frame image and the grayscale average value of the corresponding pixel block in the current frame image can be directly used to search a preset grayscale compensation table, obtain the corresponding display compensation data, i.e., the grayscale compensation value, perform display compensation on the display data in the corresponding pixel block of the current frame, and dynamically compress and store the compensated data in the corresponding storage area using the block average data compression method. In this way, compressing and storing display data and display compensation using the block average data compression method not only reduces the storage space of the display data of the current frame and the previous frame, but also improves the data processing efficiency of afterimage compensation.

[0061] Step S130: When the display picture belongs to a low-dynamic scene picture, display compensation is performed on the display data marked as the low-dynamic scene picture according to a preset second compression compensation strategy.

[0062] Specifically, for scenes marked as low-dynamic, such as application scenarios such as text reading and web browsing, it is generally required that each low-dynamic scene retain at least two frames of images.

[0063] In one embodiment, if Figure 3 As shown, performing display compensation on the display data marked as a low-dynamic scene picture according to the preset second compression compensation strategy specifically includes:

[0064] Step S131: decompressing the reference display data of the reference image in the current storage area;

[0065] Step S132: obtaining display compensation data for each pixel in the current frame image according to the decompressed reference display data;

[0066] Step S133: performing display compensation on the display data of each pixel in the current frame image based on the display compensation data of each pixel;

[0067] Step S134: dynamically compressing the compensated current frame display data;

[0068] Step S135: determining whether the compressed current frame display data is identical to the compressed reference display data;

[0069] Step S136: If they are the same, continue to perform display compensation and dynamic compression on the display data of each pixel in the next frame of image according to the reference display data, and make a judgment on the compressed display data of the next frame;

[0070] Step S137: If they are not the same, the dynamic compression process of the current frame display data is stopped, and the display compensation of the display data of each pixel in the current frame image is continued.

[0071] In one embodiment, the reference image is the first frame image in the current low-dynamic scene image, and the current frame image is any frame image after the first frame image in the current low-dynamic scene image.

[0072] For example, Figure 4 As shown, when the display device displays picture 1, the reference image stored in the storage space is the first frame image in picture 1, and the compressed data a1-a n After decompression, the reference display data is obtained, a1-a n Represents the grayscale data of the first pixel to the nth pixel in the reference image, obtains the display compensation data of each pixel in the second frame image according to the reference display data, performs display compensation on each pixel in the second frame image based on the display compensation data, and dynamically compresses the compensated display data at the same time to obtain the compressed display data of the second frame image b1-b m . Compare compressed data a1-a n With b1-b m If the compressed second frame display data is exactly the same as the compressed first frame display data, it can be considered that the second frame image and the first frame image have not changed in content, and there is no need to update the display data stored in the current storage area. When processing the display data of the third frame image, continue to use the reference display data a1-a of the first frame image. n Display compensation is performed on the display data of the third frame image, and the compensated display data of the third frame is dynamically compressed. The compressed display data of the third frame is compared with the compressed display data of the first frame to determine whether they are identical. If the compressed display data of the third frame is not identical to the compressed display data of the first frame, the dynamic compression process of the display data of the third frame is terminated, and display compensation is continued on the unprocessed display data of the third frame.

[0073] In an embodiment of the present application, when the compressed current frame display data is different from the compressed reference display data, it is determined that the display screen is switched from the current low-dynamic scene screen to another low-dynamic scene screen, and the display data of the next frame image of the current frame image is dynamically compressed and stored in the current storage area as the updated reference display data.

[0074] Specifically, when the compressed current frame display data is different from the compressed reference display data, that is, the display data of the display screen has changed, it can be considered that the display device switches from the current low-dynamic scene screen to another low-dynamic scene screen, and the screen content has changed. Figure 4As shown, when the display screen switches from screen 1 to screen 2, the display data of the first frame (K+1 frame) after the screen switch changes relative to the display data of screen 1 stored in the storage area. At this time, the reference display data in screen 1 is directly used to compensate for the display data of the K+1 frame image, thereby improving the ghosting phenomenon caused by the screen switch. For the second frame (K+2 frame) after the screen switch, since each low-dynamic scene screen maintains at least two frames of images, the display data of the K+2 frame image is the same as the display data of the K+1 frame image. Therefore, the display data of the K+2 frame image can be directly dynamically compressed and stored in the current storage area as new reference display data for display compensation of the next low-dynamic scene screen.

[0075] In this embodiment, in the frame where the screen switches (the K+1 frame), only display compensation is performed, but the data in the storage unit is not modified; and in the next frame after the screen switch (the K+2 frame), only the stored data in the storage unit is updated, but no display compensation is performed. This ensures that the display data of the next frame image after the screen switch is the same as the display data of the switching frame, thereby ensuring that no ghosting occurs when the screen switches.

[0076] In the above embodiment, the method for obtaining display compensation data includes: calculating the grayscale difference between the grayscale value of each pixel in the reference image and the grayscale value of the corresponding pixel in the current frame image; based on a preset grayscale compensation table, looking up the table to obtain the display compensation data corresponding to the grayscale difference.

[0077] The display data compensation method provided in the embodiment of the present application classifies and marks display images into high-dynamic scene images and low-dynamic scene images according to the application scenario of the display images; performs display compensation on the display data marked as high-dynamic scene images according to a preset first compression compensation strategy; and performs display compensation on the display data marked as low-dynamic scene images according to a preset second compression compensation strategy. Different compression compensation strategies are adopted according to the type of mark, which can meet the performance requirements and user experience in different application scenarios, allocate resources more effectively, and improve the overall performance and efficiency of the display device. When display compensation is performed on the display data marked as low-dynamic scene images according to the preset second compression compensation strategy, the display data of the screen switching frame is displayed compensated by the reference display data in the storage space, and by comparing the compressed current frame display data with the compressed reference display data to see whether they are the same, it is determined whether the reference display data used for display compensation needs to be updated. This not only improves the ghosting problem existing in the dynamic display process of the screen, but also reduces the storage space required to store the screen display data.
