[0002] With the development of display device manufacturing technology, organic light-emitting diode (OLED) display panels have been widely used due to their excellent brightness and contrast. However, as the usage time of OLED display panels increases, the luminous efficiency of pixels decreases, and the inconsistent operating time of OLED devices in different areas or of different colors leads to differences in the brightness of OLEDs, resulting in burn-in due to aging, which affects the user experience.

[0017] If the grayscale difference of at least one of the display areas is greater than the preset threshold, then the display image has a local static display area.

[0018] If the grayscale difference of each of the display areas is not greater than the preset threshold, then the display image does not have any local static display areas.

Detailed Implementation

[0051] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

Therefore, they should not be construed as limitations on this application. In addition, the terms "first," "second," and "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0055] It should be noted that, where there is no conflict, different features in the embodiments of this application can be combined with each other.

[0056] The inventors discovered that the current common method for eliminating burn-in is screen brightness compensation algorithm (Deburn-in, DBI). This method samples different display images at the same interval, resulting in different errors in the burn-in values ​​collected from different display images. This can lead to overcompensation or undercompensation during burn-in compensation, thus affecting the compensation effect.

[0057] For example, for some short video or chat software with local static display areas, the aging values ​​collected during aging compensation may be inaccurate, resulting in a significant grayscale difference in the image and causing obvious burn-in demarcation lines after compensation.

[0058] In view of this, this embodiment provides a solution that can solve the above problems. The solution provided in this embodiment will be described in detail below.

[0059] Please refer to Figure 1 , Figure 1 Example: A schematic flowchart of the display panel aging compensation method provided in this embodiment is shown. The display panel aging compensation method may include the following steps.

[0060] Step S110: Obtain the display image.

[0061] In this embodiment, the display image currently displayed on the display panel can be obtained, and the display image may include at least two different display areas.

[0062] For example, displaying an image can include three different display areas. Please refer to [link / reference]. Figure 2 For software such as Douyin and WeChat, the three display areas may include a dividing bar area 110 above the displayed image, a navigation bar area 130 below the displayed image, and a content display area 120 between the dividing bar area 110 and the navigation bar area 130.

[0063] Step S120: Determine at least two different display areas in the display image. For each of the at least two different display areas in the display image, calculate the grayscale difference degree corresponding to each display area. The grayscale difference degree characterizes the degree of difference in grayscale values ​​between different positions in the same display area.

[0064] In this embodiment, grayscale difference detection can be performed on each display area separately, and the grayscale difference degree corresponding to each display area in the display image can be calculated. The grayscale difference degree can refer to the degree of difference in grayscale values ​​between pixels at different positions in the same display area.

[0065] Step S130: Based on the grayscale difference of each display area, detect whether there is a local static display area in the displayed image.

[0066] In this embodiment, the grayscale difference of each display area obtained in step S120 can be used to detect whether there are local static display areas in the display image, thereby determining whether there are obvious grayscale boundaries in the display image. Local static display areas can refer to areas where the current display image does not change dynamically, or areas where the dynamic changes in the current display image are very small. For example, please refer again... Figure 2For apps like TikTok and WeChat, the static display area can refer to the dividing bar area 110 above the displayed image and the navigation bar area 130 below the displayed image. This area typically doesn't change significantly during application usage. Additionally, the displayed image may include a content display area 120, which usually experiences frequent dynamic changes during application usage.

[0067] Specifically, the grayscale difference of each display area can be used to detect whether each display area is a local static display area, that is, to detect whether the currently displayed image in each display area is dynamically changing.

[0068] Step S140: If there is a local static display area in the displayed image, the first preset sampling time interval is used to sample the displayed image to obtain the first aging data, and aging compensation is performed on the subsequent displayed image based on the first aging data.

[0069] In this embodiment, when there is a local static display area in the displayed image, the displayed image can be sampled using a first preset sampling time interval to obtain the brightness decay value of the displayed image, and the first aging data can be obtained based on the brightness decay value of the displayed image, thereby performing aging compensation on the subsequent displayed images of the display panel based on the first aging data.

[0070] Specifically, the display image is sampled using a first preset sampling time interval to obtain the grayscale value of the display image. Based on the grayscale value of the display image, the brightness decay value of the display image can be determined according to the preset lookup table. The brightness decay data can refer to the amount of pixel brightness decay within a fixed interval. The preset lookup table can be a lookup table corresponding to grayscale value and brightness decay. The preset lookup table can be generated based on multiple different grayscale brightness decay curves.

[0071] Step S150: If there is no local static display area in the displayed image, the second preset sampling time interval is used to sample the displayed image to obtain the second aging data, and aging compensation is performed on the subsequent displayed image based on the second aging data; the first preset sampling time interval is different from the second preset sampling time interval.

[0072] In this embodiment, when there is no local static display area in the displayed image, the displayed image can be sampled using a second preset sampling time interval different from the first preset sampling time to obtain the brightness decay value of the displayed image. Based on the brightness decay value of the displayed image, second aging data is obtained, and aging compensation is performed on subsequent displayed images of the display panel based on the second aging data.

[0073] Based on the above design, in the display panel aging compensation method provided in this embodiment, by calculating the grayscale difference of each display area, it is possible to detect whether there is a local static display area in the display image, thereby determining whether there is a clear grayscale boundary line in the display image. At the same time, depending on whether there is a clear grayscale boundary line in the display image, different sampling intervals can be set to sample the display image. In this way, the sampling accuracy of aging data can be improved, making the error between the collected aging data and the aging data caused by the actual use scenario smaller, thereby improving the aging compensation effect of the display panel.

[0074] In one possible implementation, please refer to Figure 3 Step S120 may include the following sub-steps.

[0075] Step S121: Determine at least two blocks with different locations in the display area.

[0076] In this embodiment, the grayscale value corresponding to each pixel in the display area can be obtained first, and the display area can be compressed into blocks to determine at least two blocks with different positions in the display area.

[0077] For example, the display area can be compressed into blocks of 4×4 or 8×8 pixels.

[0078] Step S122: For each block, calculate the average grayscale value of each pixel in the block as the grayscale data of the block.

[0079] In this embodiment, the average value of the grayscale value of each pixel in each block of the display area can be calculated to obtain the grayscale data of the block.

[0080] Step S123: Determine the grayscale difference degree corresponding to the display area based on the difference between the grayscale data of at least two blocks.

[0081] In this embodiment, grayscale data of two blocks can be selected from grayscale data of multiple blocks, and the difference between the grayscale data of the two blocks can be calculated. This difference is used as the grayscale difference degree corresponding to the display area.

[0082] In one possible implementation, when determining the grayscale difference degree corresponding to the display area based on the difference between the grayscale data of at least two blocks, the grayscale difference degree corresponding to the display area can be determined based on the difference between the maximum value and the minimum value of the grayscale data of the blocks.

[0083] In this embodiment, the maximum value and minimum value of the grayscale data of a block can be selected from the grayscale data of multiple blocks, and the maximum value and the minimum value can be subtracted to obtain the grayscale difference degree corresponding to the display area.

[0084] In one possible implementation, please refer to Figure 4 Step S130 may include the following sub-steps.

[0085] Step S131: Detect whether the grayscale difference of each display area is greater than a preset threshold.

[0086] Step S132: If the grayscale difference of at least one display area is greater than a preset threshold, then the displayed image has a local static display area.

[0087] Step S133: If the grayscale difference of each display area is not greater than the preset threshold, then there is no local static display area in the displayed image.

[0088] In this embodiment, the grayscale difference between each display area can be detected to determine whether a local static display area exists in the displayed image. If the grayscale difference of at least one display area in the displayed image is greater than the preset threshold, it indicates that a local static display area exists in the displayed image, that is, the displayed image has a clear grayscale boundary line. If the grayscale difference of each display area in the displayed image is less than or equal to the preset threshold, then the displayed image does not have a local static display area, that is, the displayed image does not have a clear grayscale boundary line. In this way, the sampling time interval can be dynamically adjusted according to the detection results.

[0089] For example, the preset threshold can be 128 gray levels.

[0090] In the display panel aging compensation method provided in this embodiment, please refer to... Figure 5 The process involves first acquiring the display image, then determining the display areas within that image, calculating the grayscale data corresponding to each block within the display area, and calculating the grayscale difference based on the grayscale data. It then determines whether the grayscale difference exceeds a preset threshold. If it does, sampling is performed at a first preset sampling time interval; otherwise, sampling is performed at a second preset sampling time interval. After sampling, compensation data is obtained and temporarily stored in internal memory (SRAM). After a certain interval, the compensation data in internal memory is transferred to external memory (Flash).

[0091] In one possible implementation, the first preset sampling time interval is less than the second preset sampling time interval.

[0092] In this embodiment, when the displayed image has local static display areas, i.e., when the displayed image has obvious grayscale boundaries, if the sampled first aging data is inaccurate, then after performing aging compensation on subsequent displayed images based on the first aging data, obvious burn-in boundaries may appear in the subsequent displayed images, thus affecting the display effect. When the displayed image does not have local static display areas, i.e., when the displayed image does not have obvious grayscale boundaries, if the sampled second aging data is inaccurate, then after performing aging compensation on subsequent displayed images based on the second aging data, the brightness of the subsequent displayed images may be lower than the initial brightness, without obvious burn-in boundaries appearing. Therefore, the first preset sampling time interval can be set to be less than the second preset sampling time interval, reducing the first preset sampling time interval and increasing the accuracy of the first aging data.

[0093] Preferably, the first preset sampling time interval is 1 second, and the second preset sampling time interval is 6 seconds.

[0094] In this embodiment, when the displayed image has a local static display area, the displayed image can be sampled using a first preset sampling time interval, that is, the displayed image can be sampled once every second; when the displayed image does not have a local static display area, the displayed image can be sampled using a second preset sampling time interval, that is, the displayed image can be sampled once every six seconds.

[0095] It should be noted that the first preset sampling time interval is not limited to 1 second, and the second preset sampling time interval is not limited to 6 seconds. The first preset sampling time interval and the second preset sampling time interval can be adjusted according to the actual application scenario.

[0096] In one possible implementation, please refer to Figure 6 The aging compensation method for display panels may also include the following steps.

[0097] Step S210: Generate compensation data based on the first aging data or the second aging data.

[0098] Step S220: The compensation data is stored in the internal memory.

[0099] Step S230: The compensation data in the internal memory is stored in the external memory; the internal memory is located inside the timing controller, and the external memory is located outside the timing controller.

[0100] In this embodiment, please refer to Figure 7After sampling the displayed image using a first or second preset sampling time interval to obtain a single sample value (first aging data or second aging data), compensation data can be generated based on the first or second aging data using a screen brightness compensation algorithm (Deburn-in, DBI). After generating the compensation data, it can be temporarily stored in internal memory, and then stored in external memory after a certain interval. When reading the compensation data, it can be read from external memory by internal memory.

[0101] Specifically, the internal memory can be static random-access memory (SRAM), and the external memory can be flash memory. The static random-access memory (SRAM) can be located inside the timing controller (TCON), and the flash memory can be located outside the timing controller (TCON).

[0102] For example, the display panel aging compensation method provided in this embodiment can be executed by a display panel or display device with a timing controller (TCON). The TCON can execute the aforementioned steps S110, S120, S130, S140, S150, etc., and store the compensation data in the static random-access memory (SRAM). After a certain period of time, the compensation data in the static random-access memory (SRAM) is stored in the flash memory.

[0103] In one possible implementation, in step S110, the number and / or location of the display area can be determined based on the content of the displayed image or the currently running application.

[0104] In this embodiment, the number and / or location of the display area may differ depending on the content of the displayed image or the currently running application. Therefore, by analyzing the content of the displayed image or the currently running application to determine the number and / or location of the display area, the accuracy of aging compensation can be improved, thereby improving the display effect and stability.
