[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of the application are for the purpose of describing specific embodiments only and are not intended to limit this application. The terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0030] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0031] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0032] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0033] It should be noted that the gamma data upgrade method of the Mini LED device provided in the embodiment of the present application is generally executed by a server. Accordingly, the gamma data upgrade device of the Mini LED device is generally configured in the server.

[0034] See also Figure 1 , Figure 1 A specific implementation of the gamma data upgrade method for Mini LED devices is shown.

[0035] It should be noted that the method of the present invention is not limited to the method of Figure 1The process sequence shown is limited to the following steps:

[0036] S1: Receive the serial number of the display, and read the preset gamma correction target effect parameters and the pre-tested native data of the display according to the serial number of the display to generate an original gamma correction data array.

[0037] Specifically, gamma correction upgrade is also called gamma data upgrade, which means that the display has display effect A after gamma correction when it is factory set, and the gamma correction upgrade makes the display have display effect B after gamma correction. In the embodiment of the present application, it is necessary to receive the serial number of the display, and then read the preset gamma correction target effect parameters and the pre-tested Native data of the display according to the serial number of the display to generate an array of original gamma correction data. Among them, Native data is the original data stored in the AUTOSAR NVM block, which is the data that the application needs to read and write. Native data is only stored in one copy in the NVM block. If the data is damaged or lost, it cannot be restored. Therefore, when writing Native data, it is necessary to ensure the reliability and consistency of the data. In the embodiment of the present application, the Native data of the display that has been pre-tested is required.

[0038] See also Figure 2 , Figure 2 A specific implementation of step S1 is shown, which is described in detail as follows:

[0039] S11: Constructing a generation tool for a gamma data BIN file, and receiving the serial number of the display through the generation tool.

[0040] S12: Reading the preset gamma correction target effect parameters and the native data of the pre-tested display according to the serial number of the display, and generating the original gamma correction data array.

[0041] Specifically, the embodiment of the present application needs to make a generation tool for the gamma data BIN file, and then call the generation tool to receive the serial number of the display, read the pre-tested native data of the display and the preset gamma correction target effect parameters according to the serial number of the display, and generate the original gamma correction data array. Among them, the generated original gamma correction data array can be a group of arrays or multiple groups of arrays, and each group of gamma effects corresponds to a group of original gamma correction data arrays. In a specific embodiment, a group of original gamma correction data arrays is 3072 (the number of gamma data can also be 256*3, 1024*3, or other values ​​multiplied by multiples of 3) 2Byte (1Byte can also be generated) gamma correction data arrays.

[0042] S2: compressing the original gamma correction data array to obtain multiple groups of basic gamma arrays.

[0043] Specifically, to ensure the security of gamma data, displays require EEPROM components to store the original gamma correction data array. However, the original gamma correction data array is relatively large, which requires more EEPROM capacity and space, resulting in high gamma data upgrade costs. Therefore, to reduce costs, it is necessary to compress the original gamma correction data array to obtain multiple sets of basic gamma arrays.

[0044] See also Figure 3 , Figure 3 A specific implementation of step S2 is shown, which is described in detail as follows:

[0045] S21: Sequentially divide the original gamma correction data array into three new gamma arrays.

[0046] S22: For each of the new gamma arrays, starting from the second bit of data of the new gamma array, sequentially calculating the difference between the subsequent bit of data and the previous bit of data to obtain a plurality of target difference values.

[0047] S23: adding the target difference to the data in the new gamma array in sequence according to a preset method to obtain a group of the basic gamma arrays. When all the new gamma arrays are compressed, multiple groups of the basic gamma arrays are obtained.

[0048] Specifically, the original gamma correction data array compression method is to divide each set of original gamma correction data arrays into three new gamma arrays, where the values ​​of each new gamma array are sequentially increased. Then, for each new gamma array, starting from the second bit of the new gamma array, the difference between the subsequent bit of data and the previous bit of data is calculated in sequence to obtain multiple target differences, and the target differences are saved; finally, the target differences are added to the previous bit of data in the two bits corresponding to the calculated target differences, and the new data is obtained. When all the data are added, the basic gamma array is obtained.

[0049] S3: performing conversion and compression processing on each group of the basic gamma arrays in turn to obtain multiple groups of compressed gamma arrays, and merging all the compressed gamma arrays to obtain a merged gamma array.

[0050] Specifically, in the embodiment of the present application, each group of basic gamma arrays needs to be converted and compressed in sequence, and the conversion and compression method of each group of arrays adopts the same method. When all basic gamma arrays are converted, all the compressed gamma arrays are merged in sequence to obtain a merged gamma array.

[0051] See also Figure 4 , Figure 4 A specific implementation of step S3 is shown, which is described in detail as follows:

[0052] S31: traversing each group of the basic gamma arrays in sequence, determining the maximum value in each group of the basic gamma arrays, and determining a grouping cardinality based on the maximum value.

[0053] See also Figure 5 , Figure 5 A specific implementation of step S31 is shown, which is described in detail as follows:

[0054] S311: traverse each group of the basic gamma arrays, identify the maximum value in each group of the basic gamma arrays, and obtain a target value.

[0055] S312: Determine the grouping cardinality based on the number of bits occupied by the target value, and save the grouping cardinality.

[0056] Specifically, each set of basic gamma arrays is traversed, and the largest value in the set of basic gamma arrays is identified and used as the target value. The grouping cardinality is then determined based on the number of bits in the target value. The grouping cardinality must satisfy the requirement that the remainder of the target value multiplied by the grouping cardinality and divided by 8 is 0, and the maximum value of the grouping cardinality is 8. In one specific embodiment, the number of bits in the target value is 5, and the grouping cardinality is 8. The grouping cardinality refers to the amount of data in each group after the basic gamma arrays are grouped.

[0057] S32: Grouping and merging the basic gamma arrays according to the grouping cardinality to obtain multiple groups of compressed gamma arrays.

[0058] See also Figure 6 , Figure 6 A specific implementation of step S32 is shown, which is described in detail as follows:

[0059] S321: Determine the number of groups based on the grouping base and the basic gamma array.

[0060] S322: Sequentially grouping the data in the basic gamma array based on the grouping number to obtain a plurality of groups and group data in each group.

[0061] S323: For the group data in each group, identify valid values ​​in the group data, and merge the valid values.

[0062] S324: After the grouped data of all groups are merged, a plurality of compressed gamma arrays are obtained.

[0063] Specifically, the number of gamma data in the basic gamma array is divided by the grouping base to obtain the number of groups. The data in the basic gamma array is then grouped based on the number of groups to obtain multiple groups and the grouped data in each group. For the grouped data in each group, valid values ​​in the grouped data are identified and merged. After the grouped data of all groups are merged, multiple compressed gamma arrays are obtained. The valid values ​​are identified by taking the value of the high-order bit 5 of each valid value in the grouped data of each group.

[0064] In a specific embodiment, the basic gamma array has 1024 gammas and the grouping base is 8. Therefore, the number of groups is calculated to be 1024 / 8 = 128. This means that the 1024 data are divided into 128 groups of 8 numbers each. The high-order 5 bits of each of the 8 numbers are then extracted and combined to form five 8-bit numbers. The resulting 1024 data is converted to 128*5 = 640 + 2 8-bit data (two bytes are used to represent the 640 number and are placed at the beginning of the compressed data for use during decompression).

[0065] S33: After all the basic gamma arrays are converted and compressed, all the compressed gamma arrays are merged to obtain the merged gamma array.

[0066] Specifically, according to steps S321-S324, each group of basic gamma arrays is converted and compressed in turn. After the conversion and compression of all basic gamma arrays are completed, all compressed gamma arrays are merged in order to obtain a merged gamma array.

[0067] S4: Determine a cyclic redundancy check code and byte information based on the serial number of the display and the combined gamma array, and add the serial number of the display, the cyclic redundancy check code and the byte information to the combined gamma array to obtain a target gamma array.

[0068] Furthermore, a specific implementation of step S4 is provided: determining the serial number byte information based on the serial number of the display, and determining the array byte information and the cyclic redundancy check code based on the merged gamma array; adding the serial number byte information and the serial number of the display before the merged gamma array, and adding the cyclic redundancy check code after the merged gamma array to obtain an initially added gamma array; adding the array byte information before the initially added gamma array to obtain the target gamma array.

[0069] Among them, the byte information includes serial number byte information and array byte information. The serial number byte information indicates how many bytes the serial number has in total. The array byte information indicates all bytes contained in the gamma array except the cyclic redundancy check code. Cyclic redundancy check code (CRC, Cyclic Redundancy Check), referred to as cyclic code, is a commonly used check code with error detection and error correction capabilities, and is widely used in early communications. Cyclic redundancy check codes are often used for data verification of external storage devices and computer synchronous communications. In an embodiment of the present application, the serial number byte information is determined based on the serial number of the display, and the serial number byte information indicates how many bytes the serial number of the display has in total; the array byte information is determined based on the merged gamma array, and the array byte information indicates all bytes contained in the array except the checksum. The cyclic redundancy check code is the checksum of all values ​​in the merged gamma array.

[0070] Specifically, the display serial number is added to the front of the combined gamma array, and the serial number byte information is added to the front of the serial number, that is, a 1-byte value is added to indicate the total number of bytes in the serial number. A 1-byte cyclic redundancy check code (the cyclic redundancy check code is equal to the checksum of all preceding values) is added to the back of the combined gamma data. The array byte information is added to the front of the combined gamma array, that is, the first 4 bytes of the combined gamma array are used to indicate all bytes contained in the array except the checksum.

[0071] S5: Writing the target gamma array into a BIN file to generate a target gamma data BIN file.

[0072] Specifically, the target gamma array is written in hexadecimal to a BIN file (binary file) named with a serial number, thereby generating a target gamma data BIN file.

[0073] In a specific embodiment, the implementation of the embodiment of the present application requires a display that supports Mini LED with a type-c interface, through which a type-c to USB female port adapter cable can be connected and a USB flash drive can be connected.

[0074] In an embodiment of the present application, a serial number of a display is received, and according to the serial number of the display, a preset gamma correction target effect parameter and the native data of the pre-tested display are read to generate an original gamma correction data array; the original gamma correction data array is compressed to obtain multiple groups of basic gamma arrays; each group of the basic gamma arrays is converted and compressed in turn to obtain multiple groups of compressed gamma arrays, and all the compressed gamma arrays are merged to obtain a merged gamma array; a cyclic redundancy check code and byte information are determined based on the serial number of the display and the merged gamma array, and the serial number of the display, the cyclic redundancy check code and the byte information are added to the merged gamma array to obtain a target gamma array; the target gamma array is written into a BIN file to generate a target gamma data BIN file. The embodiment of the present invention compresses the gamma array, reduces the size of the gamma array, reduces the space for component storage, is conducive to reducing the cost of gamma correction upgrades, and realizes the automation of reducing gamma correction upgrades without the need for professional personnel to operate, which is conducive to improving the efficiency of reducing gamma correction upgrades.
