[0007] According to a third aspect of the present application, a display device is provided, comprising: a display panel; a computer storage medium configured to store computer program instructions for performing the data processing method as described in the first aspect; and a processor configured to execute the computer program instructions to obtain compensation data for brightness compensation of the display panel.

[0008] According to a fourth aspect of the embodiments of this application, a display terminal is provided, the display terminal including a terminal device body and a display device as described in the third aspect disposed on the terminal device body.

[0009] According to a fifth aspect of the present application, an electronic device is provided, comprising: a processor, a memory, a communication interface, and a communication bus, wherein the processor, the memory, and the communication interface communicate with each other via the communication bus; the memory is used to store at least one executable instruction, wherein the executable instruction causes the processor to perform an operation corresponding to the method described in the first aspect.

[0010] According to a sixth aspect of the embodiments of this application, a computer storage medium is provided having a computer program stored thereon, which, when executed by a processor, implements the method described in the first aspect.

[0011] According to a seventh aspect of the embodiments of this application, a computer program product is provided, including computer instructions that instruct a computing device to perform an operation corresponding to the method described in the first aspect.

[0012] According to the data processing method, apparatus, display device, and display terminal provided in the embodiments of this application, the data processing method includes: acquiring multiple sets of compensation data to be compressed for a target display panel; the multiple sets of compensation data correspond to different display states of the target display panel; the compensation data are used to compensate the display brightness of the target display panel; determining target compensation data and remaining compensation data from the multiple sets of compensation data; the target compensation data is a portion of the multiple sets of compensation data; compressing the target compensation data using a first compression algorithm, and compressing the remaining compensation data using a second compression algorithm; wherein, for the same set of compensation data, the data compression amounts using the first compression algorithm and the second compression algorithm are different. In order to perform brightness compensation for different display states of the target display panel, it is necessary to store compensation data corresponding to different display states. Based on a comprehensive consideration of the compensation effect and the amount of data to be stored, this solution sets a first compression algorithm and a second compression algorithm with different data compression amounts, and uses the first compression algorithm to compress a portion of the compensation data from the multiple sets of compensation data, and uses the second compression algorithm to compress the remaining compensation data. This can reduce the amount of data that needs to be stored while ensuring the compensation effect, thereby meeting the user's storage needs. Furthermore, the data compression amounts of the first compression algorithm and the second compression algorithm are different, that is, there is a size relationship between the data compression amounts of the first compression algorithm and the second compression algorithm. Assuming that the data compression amount of the first compression algorithm is less than that of the second compression algorithm, under the condition of satisfying a fixed storage space, since the amount of compressed compensation data obtained by the first compression algorithm can be less, some storage space can be saved. Therefore, when the second compression algorithm is compressed, the remaining compensation data can be compressed with a smaller number of pixels as the compression unit, so that the compressed compensation data corresponding to the remaining compensation data has higher detail and correspondingly better compensation effect.

[0025] The specific implementation of the embodiments of this application will be further described below with reference to the accompanying drawings.

[0026] Figure 1 This is a flowchart illustrating the steps of a data processing method according to an embodiment of this application. According to a first aspect of an embodiment of this application, a data processing method is provided, referring to... Figure 1 As shown, the method includes steps S102, S104, and S106, specifically:

[0027] S102. Obtain multiple sets of compensation data to be compressed for the target display panel.

[0028] For example, the target display panel can be an OLED display panel, which is an organic light-emitting diode display panel. An OLED can be composed of a substrate, an anode, a hole transport layer, an organic light-emitting layer, an electron transport layer, and a cathode. The substrate is usually made of materials such as glass or flexible plastic, providing support for the entire device; the anode is generally made of a transparent conductive material (such as indium tin oxide, ITO) for injecting holes; the hole transport layer helps holes to be transported smoothly to the organic light-emitting layer; the organic light-emitting layer is the core part, composed of various organic materials, and different organic materials can emit different colors of light, that is, the organic light-emitting layer can include multiple pixels; the electron transport layer is responsible for transferring electrons to the organic light-emitting layer; and the cathode is used for injecting electrons.

[0029] The compensation data is used to compensate for the display brightness of the target display panel. For example, the compensation data could be voltage compensation data, etc. Multiple sets of compensation data correspond to different display states of the target display panel; that is, one set of compensation data corresponds to one display state of the target display panel. The different display states of the target display panel can be divided according to display grayscale values, such as high grayscale state, medium grayscale state, low grayscale state, etc.; or, they can also be divided according to display brightness values, such as low brightness state, medium brightness state, high brightness state, etc. Here, the different display states of the target display panel can correspond to one or more display mura types.

[0030] The grayscale of a target display panel refers to the different gray levels displayed in an image, also known as grayscale grades, grayscale levels, or grayscale range. It is usually represented numerically by the brightness or darkness of pixels in an image, and typically includes 256 grayscale levels (0-255), 1024 grayscale levels (0-1023), 4096 grayscale levels (0-4095), 65536 grayscale levels (0-65535), and so on. Low grayscale refers to the relatively darker portion of the brightness level within the entire grayscale range, that is, the grayscale level area near the black end. High grayscale refers to the relatively bright portion of the brightness level within the entire grayscale range, that is, the grayscale level area near the white end.

[0031] The Display Brightness Value (DBV) of the target display panel is a numerical value used to represent the brightness control of the display panel. It can usually be between 0 and 255. The larger the value, the brighter the corresponding display screen.

[0032] Mura refers to the uneven brightness of a target display panel, causing various imperfections. Display mura types can include linear mura, dot mura, and color mura. Linear mura appears as straight or curved areas of uneven brightness or color; dot mura appears as single or multiple isolated bright or dark spots; and color mura appears as localized color deviations when displaying solid colors or grayscale images. Different compensation data can be used for brightness compensation to achieve uniform brightness and color in different types of display mura.

[0033] S104. Determine the target compensation data and the remaining compensation data from multiple sets of compensation data.

[0034] The target compensation data consists of a subset of data from multiple sets of compensation data.

[0035] For example, multiple sets of compensation data can be divided into two parts, with each set as a whole: one part being the target compensation data and the remaining part being the residual compensation data. For instance, if the multiple sets of compensation data include five sets, one set can be designated as the target compensation data, and the remaining four sets as the residual compensation data. Alternatively, a portion of the compensation data in each set can be designated as the target compensation data, and the remaining portion of each set excluding that portion can be designated as the residual compensation data. This embodiment does not impose any limitations on this approach. Optionally, the target compensation data is suitable for compression algorithms with low data compression ratios, while the residual compensation data is suitable for compression algorithms with high data compression ratios.

[0036] In some optional embodiments, determining target compensation data and remaining compensation data from multiple sets of compensation data includes: determining target compensation data from multiple sets of compensation data based on the display state of the target display panel corresponding to each set of compensation data in the multiple sets of compensation data; and determining the data other than the target compensation data in the multiple sets of compensation data as remaining compensation data.

[0037] For example, target compensation data can be determined from multiple sets of compensation data based on the display state of the target display panel corresponding to each set of compensation data. That is, the target compensation data can be determined based on the display mura type corresponding to the display state of the target display panel. Compensation data corresponding to at least one display state can be determined as target compensation data; this embodiment does not limit this. For example, the display states corresponding to multiple sets of compensation data may include high grayscale state, low grayscale state, low brightness state, high brightness state, etc. Compensation data corresponding to a high grayscale state can be determined as target compensation data; and / or, compensation data corresponding to a low brightness state can be determined as target compensation data, etc., and this embodiment does not limit this. Then, the data other than the target compensation data in the multiple sets of compensation data are determined as the remaining compensation data. (Refer to...) Figure 2A The multiple sets of compensation data include three sets: the first set corresponds to a brightness DBV of brightness 1 and a grayscale Gray level of grayscale 2; the second set corresponds to a brightness DBV of brightness 2 and a grayscale Gray level of grayscale 1; and the third set corresponds to a brightness DBV of brightness 2 and a grayscale Gray level of grayscale 3. It can be determined that the first set of compensation data is the target compensation data, and the remaining two sets are the residual compensation data. The target compensation data is compressed using a first compression algorithm (represented by W in the figure), and the residual compensation data is compressed using a second compression algorithm (represented by RGB in the figure).

[0038] Since different display states of the target display panel may exhibit different display mura types, this embodiment determines the target compensation data and remaining compensation data from multiple sets of compensation data based on the display state of the target display panel corresponding to each set of compensation data. Different compression algorithms can then be used to compress the target compensation data and remaining compensation data. This allows for flexible selection of different compression algorithms for different display mura types, meeting the user's compensation needs for different display mura types. Furthermore, it can reduce the amount of compressed data while ensuring the compensation effect of the compressed compensation data for the corresponding display mura type, thereby improving the overall data processing efficiency.

[0039] In some optional embodiments, for the same set of compensation data, the amount of compressed compensation data obtained by the first compression algorithm is less than the amount of compressed compensation data obtained by the second compression algorithm; determining target compensation data from the multiple sets of compensation data according to the display state of the target display panel corresponding to each set of compensation data includes: determining the compensation data corresponding to the target display panel being in a high grayscale state from the multiple sets of compensation data; determining the compensation data corresponding to the target display panel being in a high grayscale state as the target compensation data; wherein, the high grayscale state indicates that the target display panel is in a state where the display grayscale value is greater than a preset grayscale threshold.

[0040] For example, for the same set of compensation data, the amount of compressed compensation data obtained by the first compression algorithm is less than that obtained by the second compression algorithm. Since the amount of compressed compensation data obtained by the first compression algorithm is smaller, while the amount of compressed compensation data obtained by the second compression algorithm is larger, the second compression algorithm, compared to the first compression algorithm, achieves higher compensation accuracy and better compensation effect. The display states of the target display panel corresponding to multiple sets of compensation data can include high grayscale state, low grayscale state, low brightness state, high brightness state, etc. A set of compensation data corresponding to the high grayscale state of the target display panel can be selected from multiple sets of compensation data and used as the target compensation data. Here, the high grayscale state indicates that the target display panel is in a state where the display grayscale value is greater than a preset grayscale threshold. The preset grayscale threshold can be flexibly set by those skilled in the art according to actual conditions. For example, when the grayscale range is 0-255 levels, the preset grayscale threshold can be 253 levels, etc. This embodiment does not limit this.

[0041] When the target display panel is in a high grayscale state, there is usually no snow mura. That is, the compressed compensation data corresponding to the high grayscale state has fewer display mura problems to solve. Therefore, in this embodiment, the compensation data corresponding to the target display panel in a high grayscale state is determined as the target compensation data. Then, the target compensation data is compressed by a first compression algorithm with a smaller compressed data volume. This can reduce the amount of data in the compressed compensation data while ensuring that the compressed compensation data has a good compensation effect when the target display panel is in a high grayscale state.

[0042] In some optional embodiments, for the same set of compensation data, the amount of compressed compensation data obtained by the first compression algorithm is less than the amount of compressed compensation data obtained by the second compression algorithm; determining target compensation data from the multiple sets of compensation data according to the display state of the target display panel corresponding to each set of compensation data includes: determining the compensation data corresponding to the target display panel being in a low brightness state from the multiple sets of compensation data; determining the compensation data corresponding to the target display panel being in a low brightness state as the target compensation data; wherein, the low brightness state indicates that the target display panel is in a state where the display brightness value is less than a preset brightness threshold.

[0043] For example, the display states of the target display panel corresponding to multiple sets of compensation data may include high grayscale state, low grayscale state, low brightness state, high brightness state, etc. A set of compensation data corresponding to the low brightness state of the target display panel can be selected from the multiple sets of compensation data and used as the target compensation data. Here, the low brightness state indicates that the target display panel is in a state where the display brightness value is less than a preset brightness threshold. The preset brightness threshold can be flexibly set by those skilled in the art according to actual conditions. For example, the brightness range is 0-255 nits, and the preset brightness threshold can be 12 nits, etc. This embodiment does not impose any limitations on this.

[0044] When the target display panel is in a low-brightness state, users often find it difficult to perceive the display mura (snow-like appearance) on the display panel. This means that the compressed compensation data for low-brightness states has fewer display mura issues to address. Therefore, in this embodiment, the compensation data corresponding to the target display panel in a low-brightness state is determined as the target compensation data. Then, a first compression algorithm with a smaller compressed data size is used to compress the target compensation data, resulting in a smaller compressed compensation data size while ensuring good compensation effect for the target display panel in a low-brightness state. Furthermore, given a fixed storage space requirement, the reduced data size of the compressed compensation data obtained from the first compression algorithm saves storage space. This allows the remaining compensation data to be compressed using a smaller number of pixels as the compression unit during the second compression algorithm, resulting in higher detail in the compressed compensation data and a better compensation effect.

[0045] S106. The target compensation data is compressed using the first compression algorithm, and the remaining compensation data is compressed using the second compression algorithm.

[0046] Specifically, for the same set of compensation data, the compression amounts obtained by the first compression algorithm and the second compression algorithm are different. Optionally, for the same set of compensation data, the compressed compensation data obtained by the first compression algorithm is smaller than the compressed compensation data obtained by the second compression algorithm.

[0047] For example, the multiple sets of compensation data include 5 sets of compensation data. One set of compensation data can be identified as the target compensation data, and the remaining 4 sets are the residual compensation data. The target compensation data is compressed using a first compression algorithm to obtain 1 set of compressed compensation data. The residual compensation data is compressed using a second compression algorithm to obtain 4 sets of compressed compensation data. The 1 set and 4 sets of compressed compensation data are stored for brightness compensation during application to the target display panel.

[0048] In some optional embodiments, the target compensation data includes sub-pixel compensation data corresponding to each color channel of multiple pixels. The process of the first compression algorithm to compress the target compensation data includes: fusing the sub-pixel compensation data corresponding to each color channel of a single pixel in the target compensation data to obtain multiple pixel compensation data; and fusing the pixel compensation data according to a first preset number of compressed pixels to obtain multiple compressed compensation data.

[0049] For example, the target display panel includes multiple pixels, each pixel including sub-pixels corresponding to three color channels: red, green, and blue. Each pixel then includes sub-pixels R, G, and B. The target compensation data includes sub-pixel compensation data corresponding to each color channel of the multiple pixels. When compressing the target compensation data using the first compression algorithm, the sub-pixel compensation data corresponding to each color channel of each pixel can be fused first to obtain multiple pixel compensation data corresponding to multiple pixels. Then, according to a first preset number of compressed pixels, the pixel compensation data is fused to obtain multiple compressed compensation data corresponding to multiple pixel blocks. Each pixel block includes multiple pixels corresponding to the first preset number of compressed pixels. Here, the first preset number of compressed pixels can be flexibly set by those skilled in the art according to actual conditions. For example, the first preset number of compressed pixels can be 2, 4, or 8; this embodiment does not limit this. Assuming the target compensation data includes sub-pixel compensation data corresponding to each color channel of 20 pixels (a total of 60 sub-pixel compensation data), the first step is to fuse the three sub-pixel compensation data corresponding to each color channel of each pixel to obtain 20 pixel compensation data corresponding to 20 pixels. Then, assuming the first preset number of compressed pixels is 4, the data is fused in groups of 4 pixels to obtain 5 compressed compensation data. Here, the fusion method for the compensation data can be averaging. For example, assuming the sub-pixel compensation data corresponding to the R, G, and B color channels of a single pixel are 25, 30, and 35 respectively, fusing the sub-pixel compensation data corresponding to each color channel of a single pixel can yield the average value of the sub-pixel compensation data corresponding to the R, G, and B color channels, i.e., (25+30+35) / 3 = 30, resulting in a pixel compensation data of 30 for a single pixel. Similarly, fusing multiple pixels (i.e., the first preset number of compressed pixels) in a group can also use an algorithm that averages the four pixel compensation data, which will not be elaborated upon in this embodiment.

[0050] In this embodiment, the first compression algorithm can fuse the sub-pixel compensation data corresponding to each color channel of a single pixel in the target compensation data to obtain multiple pixel compensation data; according to the first preset number of compressed pixels, the pixel compensation data is fused to obtain multiple compressed compensation data, which can greatly reduce the amount of data of the compressed compensation data and meet the user's storage needs.

[0051] In some optional embodiments, the remaining compensation data includes sub-pixel compensation data corresponding to each color channel of multiple pixels. The process of the second compression algorithm to compress the remaining compensation data includes: fusing the sub-pixel compensation data corresponding to each color channel in the remaining compensation data according to the second preset number of compressed pixels to obtain multiple compressed compensation data corresponding to each color channel.

[0052] For example, the remaining compensation data also includes sub-pixel compensation data corresponding to each color channel of multiple pixels. When the target compensation data is compressed using the second compression algorithm, the sub-pixel compensation data corresponding to each color channel of the pixel is fused according to the second preset number of compressed pixels to obtain multiple compressed compensation data corresponding to each color channel. That is, according to the second preset number of compressed pixels, the sub-pixel compensation data of the R color channel of the pixel is fused to obtain multiple compressed compensation data of the R color channel; the sub-pixel compensation data of the G color channel of the pixel is fused to obtain multiple compressed compensation data of the G color channel; and the sub-pixel compensation data of the B color channel of the pixel is fused to obtain multiple compressed compensation data of the B color channel. Here, the second preset number of compressed pixels can be flexibly set by those skilled in the art according to the actual situation. For example, the second preset number of compressed pixels can be 2, 4, or 8, and this embodiment does not limit this. The second preset number of compressed pixels can be the same as or different from the first preset number of compressed pixels, and this embodiment does not limit this. Assuming the remaining compensation data includes sub-pixel compensation data for each color channel of 20 pixels (a total of 60 sub-pixel compensation data), and assuming the second preset number of compressed pixels is 4, then by grouping 4 pixels together, the sub-pixel compensation data for each color channel is fused to obtain 5 compressed compensation data for the R color channel, 5 compressed compensation data for the G color channel, and 5 compressed compensation data for the B color channel. Here, the compensation data can be fused by averaging. For example, grouping 4 pixels together, assuming the sub-pixel compensation data for the R color channel for the 4 pixels are 20, 20, 30, and 30 respectively, then averaging the sub-pixel compensation data for the R color channel is (20+20+30+30) / 4 = 25, resulting in a compressed compensation data of 25 for the R color channel.

[0053] In this embodiment, the second compression algorithm can fuse the sub-pixel compensation data corresponding to each color channel in the remaining compensation data according to the second preset number of compressed pixels to obtain multiple compressed compensation data corresponding to each color channel. Thus, when performing brightness compensation on the target display panel, targeted compensation can be performed for each color channel, which can improve the compensation effect.

[0054] In some alternative embodiments, the number of second preset compressed pixels is less than the number of first preset compressed pixels.

[0055] For example, assuming the target data size of the compressed compensation data is 7.5 Mbits, refer to... Figure 2BAssuming a set of compensation data includes 5,054,400 sub-pixel compensation data of 1,684,800 pixels, and multiple sets of compensation data are compressed using only the second compression algorithm (RGBMode), the number of compressed pixels is 4. The number of compressed compensation data obtained by compressing multiple sets of compensation data using the second compression algorithm is 1,263,600, and the data size is 7.5 Mbits.

[0056] In this embodiment, a first compression algorithm is used to compress the target compensation data in multiple sets of compensation data, and a second compression algorithm is used to compress the remaining compensation data in multiple sets of compensation data. Furthermore, the second preset number of compressed pixels corresponding to the second compression algorithm can be set to be less than the first preset number of compressed pixels corresponding to the first compression algorithm. Figure 2C Assuming the first preset number of compressed pixels is 4, and Figure 3 The second compression algorithm (RGB Mode) corresponds to the same number of compressed pixels, but the second preset number of compressed pixels for the second compression algorithm is reduced to 2. At this point, multiple sets of compensation data are divided into target compensation data (1,263,600 sub-pixel compensation data pixels) and remaining compensation data (421,200 sub-pixel compensation data pixels). The number of compressed compensation data pixels obtained by compressing the target compensation data using the first compression algorithm (White Mode) can be 315,900, and the data size can be 1.875 Mbits. The number of compressed compensation data pixels obtained by the second compression algorithm can be 631,800, and the data size can be 3.75 Mbits. Therefore, the total data size is 5.625 Mbits.

[0057] In this embodiment, when the same storage space requirement needs to be met, the number of second preset compressed pixels corresponding to the second compression algorithm can be set to be less than the number of first preset compressed pixels corresponding to the first compression algorithm. This allows the amount of data in the compressed compensation data obtained by the first compression algorithm to be less, thereby saving some storage space. Furthermore, when the second compression algorithm compresses the data, the remaining compensation data can be compressed in units of a smaller number of pixels, resulting in higher detail in the compressed compensation data corresponding to the remaining compensation data and a better compensation effect.

[0058] In summary, to perform brightness compensation for different display states of the target display panel, it is necessary to store compensation data corresponding to different display states. Based on a comprehensive consideration of the compensation effect and the amount of data to be stored, the data processing method in this embodiment sets up a first compression algorithm and a second compression algorithm with different data compression amounts. The first compression algorithm is used to compress a portion of the compensation data from multiple sets of compensation data, while the second compression algorithm is used to compress the remaining compensation data. This reduces the amount of data that needs to be stored while ensuring the compensation effect, thus meeting the user's storage requirements. Furthermore, the first and second compression algorithms have different data compression amounts, meaning there is a relationship between their compression amounts. Assuming the first compression algorithm's compression amount is less than the second compression algorithm's, under the condition of a fixed storage space, since the compressed compensation data obtained through the first compression algorithm can be smaller, some storage space can be saved. Therefore, when the second compression algorithm compresses, the remaining compensation data can be compressed using fewer pixels as the compression unit, resulting in higher detail in the compressed compensation data corresponding to the remaining compensation data and a better compensation effect.

[0059] Reference Figure 3 The diagram shows a structural block diagram of a data processing apparatus according to an exemplary embodiment of the present application.

[0060] According to a second aspect of the embodiments of this application, a data processing apparatus is provided, including an acquisition module 302, a first calculation module 304, and a second calculation module 306.

[0061] The acquisition module 302 is used to acquire multiple sets of compensation data to be compressed for the target display panel; the multiple sets of compensation data correspond to different display states of the target display panel; the compensation data is used to compensate for the display brightness of the target display panel; the first calculation module 304 is used to determine the target compensation data and the remaining compensation data from the multiple sets of compensation data; the target compensation data is a portion of the multiple sets of compensation data; the second calculation module 306 is used to compress the target compensation data using a first compression algorithm and to compress the remaining compensation data using a second compression algorithm; wherein, for the same set of compensation data, the data compression amounts obtained by the first compression algorithm and the second compression algorithm are different.
