[0002] During the manufacturing process of display panels, due to process limitations, the luminance of each sub-pixel may be inconsistent, resulting in uneven display brightness and various trace phenomena, seriously affecting the user's viewing experience.

These display devices also face the problem of uneven display brightness during the manufacturing process.

Demura compensation is a method used to eliminate display mura and achieve uniform brightness. However, in practice, the compensation data formats vary depending on the needs of different display manufacturers and customers.

[0054] The present application provides a DeMura data compensation method, system, device, and storage medium, which can effectively compensate for display panels and adapt to the needs of different panels, thereby reducing production costs, improving compensation efficiency, and improving the picture quality of display devices.

[0055] See also Figure 1 In a first aspect, the present application provides an embodiment of a DeMura data compensation method, comprising:

[0056] 101. Obtain compensation information of a display panel to be compensated, where the compensation information includes compensation IP and user demand information;

[0057] 102. Process the display panel to be compensated according to a compensation algorithm to obtain compensation data;

[0058] 103. Generate a configuration file according to the compensation information, where the configuration file includes target general parameters and target commands;

[0059] 104. Parse the compensation data using the target general parameters and the target command to generate a binary file;

[0060] 105 . Burn the binary file into the display panel to be compensated, so as to complete the update of DeMura compensation data of the display panel to be compensated.

[0061] In this application, the compensation information of the display panel to be compensated is first obtained, and the compensation information includes the compensation IP and user demand information. Then, the display panel to be compensated is processed according to the compensation algorithm to obtain compensation data. Furthermore, a configuration file is generated based on the compensation information. The configuration file includes target general parameters and target commands. After obtaining the target general parameters and target commands, the compensation data is parsed through the target general parameters and target commands to generate a binary file. Finally, the generated binary file is burned into the display panel to be compensated to complete the update of the DeMura compensation data of the display panel to be compensated.

[0062] It can be further seen that by setting universal parameters and commands, the binary data formats required by different customers and different compensation IPs can be abstractly expressed in the form of parameters and commands, so that the binary data can be burned into the display panel for compensation processing.

[0063] Specifically, in step 101, compensation information for the display panel to be compensated is obtained. The compensation information includes compensation IP and user requirement information. The compensation IP refers to the software module used for DeMura compensation, which contains the core logic and parameter settings of the compensation algorithm, and is not specifically limited here. The compensation IP is obtained to ensure that the compensation data can be converted according to the format of the compensation IP. User requirement information includes the user's expectations for compensation effect, requirements for compensation accuracy, and requirements for compensation speed. By obtaining compensation information, it is helpful to customize the corresponding compensation plan to meet the needs of different users.

[0064] In step 102, the display panel to be compensated is processed according to the compensation algorithm to obtain compensation data. Specifically, the display panel to be compensated is analyzed and processed using a CSV data file saving algorithm commonly used in the industry to obtain compensation data. After obtaining the compensation data, step 103 is executed.

[0065] In step 103, a configuration file is generated based on the compensation information. Specifically, this is based on defined universal parameters and commands. These universal parameters and commands are described in subsequent embodiments and are not detailed here. Furthermore, the compensation IP and user requirement information in the compensation information can be presented using standardized universal parameters and commands. Specifically, the compensation IP and user requirement information requirements can be presented using target universal parameters and target commands.

[0066] In step 104, the compensation data is parsed through the target general parameters and target commands to generate a binary file, wherein the target general parameters and target commands in the configuration file are used to parse the compensation data, that is, under the action of the target general parameters and target commands, the compensation data can be converted into a format that can be directly understood and applied by the display panel. The generated binary file is a manifestation of this format, and the binary file contains all necessary compensation information and instructions for the display panel to be compensated. After obtaining the binary file, the binary file can be prepared to be burned into the display panel to be compensated.

[0067] In step 105, the binary file is sent to the compensation IP chip of the display panel to be compensated through the burner to complete the update of the DeMura compensation data of the display panel to be compensated. Specifically, the generated binary file is burned into the display panel to be compensated. Usually, a specific programming tool or device is used to write the data in the binary file into the IP compensation chip of the display panel to be compensated. After the burning is completed, the display panel to be compensated will display according to the new compensation data, thereby improving the problem of uneven brightness or color deviation and achieving the purpose of DeMura compensation.

[0068] Reference Figure 2 According to some embodiments of the present invention, in step 103, a configuration file is generated based on the compensation information. The configuration file includes target general parameters and target general commands, and specifically may include, but is not limited to, the following:

[0069] 201. Define common parameters and commands;

[0070] 202. Generate the configuration file from the compensation information using the general parameters and commands, where the configuration file includes the target general parameters and target commands.

[0071] Defining common parameters and commands is a crucial step in the DeMura data compensation process, as they are essential for subsequent compensation data conversion and configuration file creation. For common parameters, refer to Table 1; for command descriptions, refer to Tables 2 through 12; and for variable parameter settings, refer to Tables 13 through 15.

[0110]

[0111] Table 15: Variable parameter automatic filling command table

[0112]

[0113] The above common parameters are standardized and are used to describe the characteristics and format of compensation data, including but not limited to the resolution, color depth, data format, size and location of the compensation area, etc. The definition of common parameters ensures the consistency and accuracy of compensation data during generation, transmission and application.

[0114] Commands are instructions for instructing the display panel on how to parse and apply compensation data, including commands for writing data, starting the compensation process, and verifying data. The definition of these commands enables the configuration file to clearly tell the display panel how to process the received compensation data.

[0115] Then, the compensation information may be generated into a configuration file using general parameters and commands, wherein the configuration file includes target general parameters and commands for converting the compensation data into a binary file.

[0116] Specifically, first, the previously obtained compensation information is used as input, then the compensation information is processed and formatted according to the defined general parameters and commands, and finally, the processed general parameters and commands are combined to generate a complete configuration file.

[0117] Reference Figure 3 According to some embodiments of the present invention, in step 104, parsing the compensation data using the target general parameters and the target command to generate a binary file may specifically include, but is not limited to, the following:

[0118] 301. Read the compensation data and the configuration file through a parameter command parser to obtain a target configuration file, where the target configuration file includes target general parameters and the target command for converting the compensation data into the binary file;

[0119] 302. Parse the compensation data using the target general parameters and the target command to generate the binary file, where the binary file is a converted file that conforms to the compensation IP of the display panel to be compensated.

[0120] In the embodiment of this application, the parameter command parser is essentially a program implemented in a programming language. It inputs compensation data and a configuration file and then generates a binary file corresponding to the current compensation IP. The parameter command parser includes four functions: reading compensation data and configuration files, parsing parameters and commands, and controlling the generation of binary files. The specific steps are as follows:

[0121] First, read the compensation data and configuration file. Specifically, in the display panel industry, the compensation data generated by the algorithm is generally saved in a CSV file according to the agreed format. The CSV file includes information such as binding points, table data height, and table data. Then the command parser will verify the parameters in the configuration file and CSV data, and read the corresponding compensation data from the CSV data.

[0122] Then the configuration file is further read. The configuration file is a collection of general parameters, variable parameters and data conversion commands written according to general parameters and commands, based on customer needs and the requirements of the compensation IP. The configuration file contains detailed target general parameters and the target commands for converting the compensation data into a binary file.

[0123] After the target general parameters and the target command are acquired, the target general parameters and the target command are further used to actually process the compensation data.

[0124] The target general parameters are used to determine how to process compensation data, such as the data arrangement, the meaning of each data point, and the required correction coefficients. These parameters enable necessary conversions and adjustments to the compensation data. The target commands, which are not specifically defined here, provide guidance on how to generate the final binary file. These commands include writing the compensation data to the file in a specific format, adding necessary file headers or checksums, and ensuring the file conforms to the format required by the display panel's compensation IP.

[0125] After executing the target command and applying the target general parameters, the compensation data can be converted into a binary file. This file is the final form of the compensation data and can be directly read and applied by the compensation IP of the display panel to be compensated. This binary file has been converted, that is, the binary file has been converted into a specific format that can be understood and processed by the display panel to be compensated.

[0126] Reference Figure 4 According to some embodiments of the present invention, parsing the compensation data using the target general parameters and the target command in step 302 to generate the binary file may specifically include, but is not limited to, the following:

[0127] 401. Determine an area to be filled using the target general parameters and the target command;

[0128] 402. Parse the compensation data to generate data to be filled;

[0129] 403. Fill the to-be-filled data into the to-be-filled area according to a configuration order to generate the binary file.

[0130] In the examples of this application, refer to Figure 2 The general parameters and commands defined in are used to specifically describe the process of generating binary files from compensation data and configuration files:

[0131] First parse the control bin header file filling:

[0132] The parameters that control the filling of the header file are mainly the contents of the [CmdLst] and [AddrList] parts of the configuration file. After the parameter command parser reads the configuration file, it will generate a set of commands that control the generation of the header file. This set of commands consists of [CmdLst] and the commands after the parameter command parser parses the [AddrList] part.

[0133] Among them, the commands that control the filling of the header file are completed by the four commands set, digit, int, and str in the general commands. After parsing the content of the variable parameter field, the parameter command parser will retrieve the four commands set, digit, int, and str in the configuration list to fill the header area of ​​the binary file.

[0134] Specifically, at the beginning, the parameter command parser will set all the areas of the entire binary file to zero, and then parse the contents of the four commands "set", "digit", "int", and "str" ​​in the configuration to fill the header file area of ​​the binary file in the order of the configuration commands.

[0135] Then fill the Table data area:

[0136] Specifically, the Table data area is mainly the area after the header area in the binary file. It mainly controls the reading of compensation data through the parameter contents of the [baseInfo], [DataTabelList] and [AddrList] parts in the configuration file, and then converts the compensation data into the table area of ​​the binary file.

[0137] For example: The parameter command parser knows from the dataWidth and dataHeight parameters that the width and height of a group of data in the compensation data are 481 and 271 respectively. From the PanelNum and GrayList parameters, it can be known that there are a total of 3 groups of compensation data in the compensation data, corresponding to the three binding points of 240, 512, and 900 respectively. From the fillWidth parameter, it can be known that each row of the table area in the binary file is filled with 481 data. From the tableWidth parameter, it can be known that each row of data in the binary file occupies 484 bytes, and the unfilled areas are filled with zeros. From the HeadLength parameter, it can be known that the length of the header area of ​​the binary file is 544 bytes, which is 0x220 in hexadecimal.

[0138] The parameter command parser uses the command table,1,0,0x0220 to indicate that the table area in the binary file starts at position 0x0220. The entire binary file has only one table area. The command flash,1,0x060334 indicates that the current compensation IP has only one binary file with a length of 0x060334.

[0139] The parameter parser uses the control command fill,1,8,0,10,0,1 according to the corresponding parameters to cyclically fill the data in the compensation data into the table area of ​​the binary file. For example, the first value of the compensation data, 247.559, is first rounded to 248, then the binding point value 240 is subtracted to get 8, and then filled into the 0x220 position of the binary file.

[0140] Finally, the parsing control check code is generated:

[0141] The checksum control command is in the [CrcList] field of the configuration file. The obtained checksum is used to verify the contents of the header area and table area in the binary file, and the calculated checksum is filled into the binary file.

[0142] If the data content of the generated binary file is inconsistent, it may be because the dataFlip parameter in the configuration file is 1. When the parameter is 0, no processing is performed. When the parameter is 1, after the parameter parser fills the header area and table area of ​​the binary file and the checksum calculation is completed, the parameter parser will flip the data content in the binary file every 4 bytes. Finally, after the parameter parser completes the data filling, it can save the data as a binary file.

[0143] Reference Figure 5 According to some embodiments of the present invention, in step 105, sending the binary file to the compensation IP chip of the display panel to be compensated through a burner to complete the update of DeMura compensation data of the display panel to be compensated may specifically include, but is not limited to, the following:

[0144] 501. Clearing original DeMura compensation data in the display panel to be compensated;

[0145] 502. Send the binary file to the compensation IP chip of the display panel to be compensated through a burner to obtain readback data;

[0146] 503. Compare the read-back data with the binary file to see whether they are consistent;

[0147] 504. If yes, then the update of the DeMura compensation data of the display panel to be compensated is completed; if not, the binary file in the display panel to be compensated is cleared again, and the binary file is continued to be sent to the compensation IP chip of the display panel to be compensated through the burner to obtain readback data, and the readback data is compared with the binary file to see whether they are consistent; if yes, the step of updating the DeMura compensation data of the display panel to be compensated is completed.

[0148] In the embodiment of the present application, before burning the binary file to the display panel to be compensated, it is first necessary to clear the original DeMura compensation data in the display panel to be compensated in order to avoid conflict or interference between the new compensation data and the old data.

[0149] After clearing the original compensation data, the next step is to send the binary file to the compensation IP chip of the display panel to be compensated through the burner. The burner is a hardware device. During this process, the burner will send the data in the binary file to the compensation IP chip bit by bit or block by block according to the predetermined protocol and format.

[0150] At the same time, in order to verify the accuracy of the burning, a readback function will be provided, that is, the data is read out immediately after being written to obtain the readback data. After obtaining the readback data, the readback data is compared with the binary file to see if they are consistent. The comparison process involves bit-by-bit or byte-by-byte comparison to ensure that there is no data loss or error. If the comparison result shows that the readback data is consistent with the binary file, then it can be confirmed that the new compensation data has been correctly burned into the display panel to be compensated. At this point, it can be considered that the update of the DeMura compensation data has been completed, and the display panel to be compensated can now display according to the new compensation data, thereby improving the problem of uneven brightness or color deviation.

[0151] If the comparison results show that the readback data is inconsistent with the binary file, it indicates that an error or data loss may have occurred during the programming process. In this case, it is necessary to perform the clear operation again to remove the compensation data that may have been partially written but incorrect. Then, try again to send the binary file through the programmer to the compensation IP chip of the display panel to be compensated, obtain new readback data, and repeat the comparison process with the binary file until the two are completely consistent. This programming and readback process ensures that the DeMura compensation data is updated accurately and reliably, thereby maximizing the display quality of the display panel.
