[0035] In order to facilitate the understanding of the present application, the present application will be described more comprehensively below with reference to the relevant drawings. The preferred embodiments of the present application are given in the drawings. However, the present application can be implemented in different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present application more thorough and comprehensive.
[0036] Figure 1 A schematic flow chart of a method for generating LED display correction data according to an embodiment of the present application is shown. Figure 2 A schematic flow chart of another method for generating LED display correction data provided according to an embodiment of the present application is shown.
[0037] The LED display correction data generation method provided in the embodiment of the present application can, for example, implement adding record information to general display correction data, or implement adding record information to display correction data to which other information has been added.
[0038] like Figure 1 As shown, the LED display correction data generation method includes the following steps:
[0039] Step S100: Encode and convert each character in the record information to obtain a corresponding record value. The record information includes correction software version information, correction hardware version information, etc.
[0040] In some embodiments, see Figure 2 , step S100 includes the following steps:
[0041] Step S110: Encode each character in the record information to obtain the corresponding hexadecimal number. Exemplarily, take the record information "CHIPONE" as an example. First, encode the record information. For example, convert the record information "CHIPONE" into ASCII code (American Standard Code for Information Interchange). Correspondingly, each character in the record information corresponds to a hexadecimal number. Among them, the hexadecimal number of "C" is "43", the hexadecimal number of "H" is "48", the hexadecimal number of "I" is "49", the hexadecimal number of "P" is "50", the hexadecimal number of "O" is "4f", the hexadecimal number of "N" is "4e", and the hexadecimal number of "E" is "45".
[0042] Step S120: Convert each hexadecimal number into a decimal number. Exemplarily, convert the hexadecimal number of each character in the record information "CHIPONE" into a decimal number. Correspondingly, the hexadecimal number of "C" converted into a decimal number of "67", the hexadecimal number of "H" converted into a decimal number of "72", the hexadecimal number of "I" converted into a decimal number of "73", the hexadecimal number of "P" converted into a decimal number of "80", the hexadecimal number of "O" converted into a decimal number of "79", the hexadecimal number of "N" converted into a decimal number of "78", and the hexadecimal number of "E" converted into a decimal number of "69".
[0043] Step S130: Setting a decimal digit threshold corresponding to each character in the record value. In order to facilitate subsequent decoding of the record information from the display correction data, in this embodiment, a decimal digit threshold corresponding to each character in the record value is set. Exemplarily, the digit threshold is set to 3, for example.
[0044] Step S140: fill the high digits of the decimal numbers whose digits do not reach the digit threshold with zeros. Exemplarily, the decimal number of each character in the record information "CHIPONE" is processed. Correspondingly, the decimal number of "C" is processed as "067", the decimal number of "H" is processed as "072", the decimal number of "I" is processed as "073", the decimal number of "P" is processed as "080", the decimal number of "O" is processed as "079", the decimal number of "N" is processed as "078", and the decimal number of "E" is processed as "69".
[0045] Step S200: Obtain at least one correction value of a sub-pixel from the stored display correction data, wherein the correction value includes at least a correction coefficient. The display correction data is stored in a text format, for example. Each row represents the correction data of a pixel, wherein the first two values are pixel coordinates, and the following values are correction values corresponding to each sub-pixel color. The correction value includes a correction coefficient corresponding to each sub-pixel color. This universal storage method uses a plain text format so that it can be used by various control card systems.
[0046] In some embodiments, see Figure 2 , step S200 includes the following steps:
[0047] Step S210: Obtain n correction values including only the correction coefficient from the stored display correction data according to the accuracy of the correction coefficient, where n is the number of characters in the record information and n is a positive integer. Further, the accuracy of the correction coefficient of each sub-pixel is consistent. Exemplarily, for example, the correction values including only the correction coefficient in the correction value are obtained sequentially from the display correction data. Further, the n correction values including only the correction coefficient are obtained by judging whether the number of digits after the decimal point of the correction value meets the accuracy of the correction coefficient.
[0048] Step S300: Add the recorded value after the correction coefficient in the correction value of at least one sub-pixel to obtain a new correction value. Further, a decimal number corresponding to at most one character in the recorded value is added after the correction coefficient of a sub-pixel.
[0049] In some embodiments, see Figure 2 , step S300 includes the following steps:
[0050] Step S310: Write the decimal number corresponding to each character in the recorded value in sequence after the corresponding correction value that only includes the correction coefficient. Further, taking the case that each correction value in the display correction data only includes the correction coefficient as an example, write each decimal number of the recorded value in sequence after the corresponding correction value of the acquired correction coefficient. Exemplarily, take a pixel having 9 sub-pixel correction coefficients (correction values) as an example. Write the processed decimal number corresponding to each character in the recorded information "CHIPONE" one by one after the correction coefficients of the first 7 sub-pixels of the first pixel to obtain 7 new correction values.
[0051] Step S320: Store the new correction value into the display correction data to correspond to the correction value covering at least one sub-pixel. Exemplarily, the correction values of the first 7 sub-pixels of the first pixel are replaced with the generated 7 new correction values. For example, the correction coefficient of the first sub-pixel of the first pixel is replaced with the new correction value after adding the processed decimal number corresponding to the character "C" after the correction coefficient.
[0052] The display correction data generated by the embodiment of the present application adds record information, and utilizes the correction coefficient accuracy limit of the display correction data to implement additional information storage in the general correction data, which does not affect the use of the display correction data and can perform traceability management or version tracing on the display correction data as needed.
[0053] It should be noted that when the written record information needs to be updated, for example, the new record information can be continued to be written through the above-mentioned LED display correction data generation method without changing the original record information; or the original record information can be deleted first and then the new record information can be continued to be written through the above-mentioned LED display correction data generation method.

Further, the acquisition unit 410 acquires n correction values including only the correction coefficient from the stored display correction data according to the accuracy of the correction coefficient, where n is the number of characters in the record information.

Further, the processing unit 420 encodes each character in the record information to obtain a corresponding hexadecimal number, converts each hexadecimal number into a decimal number, sets a digit threshold of the decimal number corresponding to each character in the record value, and fills the high digit of the decimal number whose digit does not reach the digit threshold with zero. Further, the processing unit 420 also writes the decimal number corresponding to each character in the record value in sequence after the corresponding correction value including only the correction coefficient, and stores the new correction value in the display correction data to correspond to the correction value covering at least one sub-pixel.
