[0026]

First Embodiment

[0027] See Figure 1 , the first embodiment of the present invention provides a data storage method, including the following steps:

[0028] S10. Obtain a first output voltage data group corresponding to Gamma and VCOM in a first format;

[0029] S20. Generate a corresponding first code encoding group according to the first output voltage data group and a calculation function;

[0030] S30. Store the first code encoding group at a first address of a memory storage chip;

[0031] S40. Obtain corresponding second code encoding data from the first code encoding group according to a second output voltage data group in a second format, where the second output voltage data group includes some output voltage data in the first output voltage data group;

[0032] S50. Store the second code encoding data at a second address in the memory storage chip.

[0033] In liquid crystal display technology, Gamma and VCOM are two key parameters that have an important impact on the display effect. Gamma is a parameter that describes the non-linear relationship between the input signal and the display output. Gamma correction is used to adjust the contrast and brightness of the image. It is based on the non-linear perception of brightness by the human eye and compensates for the brightness characteristics of the display device through power-law conversion. The Gamma value reflects the sensitivity of the human brain to changes in brightness, remapping the brightness changes in the display device to achieve more accurate color display. VCOM (common voltage) is the reference voltage for the deflection of liquid crystal molecules and has a direct impact on liquid crystal display. The specific voltage value is determined according to the input data and the magnitude of the VCOM voltage, used to display various different gray levels to achieve color display. By precisely controlling these two parameters, higher-quality image display can be achieved, reducing flicker and color distortion.

[0034] In the embodiment of the present invention, the execution subject can be, for example, a computer. Specifically, it can be a debugging software installed on the computer that executes the data storage method through the processor. The computer can be electrically connected to the memory storage chip of the liquid crystal panel. When performing automatic Gamma correction and automatic anti-flicker on the liquid crystal panel for the first time in the production line, it is necessary to debug the liquid crystal panel to obtain the first output voltage data set corresponding to Gamma and VCOM in the first format. Then, according to the first output voltage data set, the corresponding first code encoding set is obtained. Specifically, the corresponding first code encoding set is generated according to the first output voltage data set and the calculation function. In one implementation manner of this embodiment, the calculation function can be, for example, a multivariate polynomial equation. In another implementation manner of this embodiment, the calculation function can also be, for example, a quadratic equation of one variable. In this embodiment, the first output voltage data set includes multiple actual output voltages obtained through debugging. By substituting the multiple actual output voltages in the first output voltage data set into the calculation function, multiple corresponding encoding codes can be obtained, that is, the corresponding first code encoding set is obtained. Then, the obtained first code encoding set is written into the first address of the memory storage chip, or the first output voltage data set can also be stored in the first address of the memory storage chip together.

[0035] Then, corresponding second code encoding data is obtained from the first code encoding group according to the second output voltage data group in the second format. According to the second format and the first output voltage data group, a corresponding second output voltage data group can be obtained. The second output voltage data group includes some output voltage data in the first output voltage data group. Then, multiple corresponding code encodings are obtained from the first code encoding group according to the actual output voltages in the second output voltage data group to form a second code encoding group. Then, the obtained second code encoding group is written into the second address of the memory storage chip. For example, the second output voltage data group can also be stored in the second address of the memory storage chip together. The second format here can be, for example, other formats different from the first format, and can also include a third format, a fourth format, etc., so as to obtain multiple output voltage data groups and code encoding groups in different formats and store them in different addresses of the memory storage chip.

[0036] In the embodiment of the present invention, by obtaining the first output voltage data group corresponding to Gamma and VCOM in the first format, then obtaining the corresponding first code encoding group through a calculation function, and then obtaining the corresponding second code encoding data from the first code encoding group according to the output voltage data groups in different formats, and storing different code encoding groups in different addresses, the liquid crystal panel can be made to match multiple different gamma correction chips, and different gamma correction chips can read the debugging data in the corresponding format from the corresponding addresses, improving the product adaptability.

[0037] Further, step S50 stores the second code encoding data in the second address in the memory storage chip, specifically: after performing corresponding format conversion on the second code encoding data according to the second format, it is stored in the second address in the memory storage chip. For example, the second code encoding data is in decimal, while the required number systems for different gamma correction chips may be different, such as hexadecimal, binary, etc. Therefore, according to customer requirements, the decimal of the second proxy encoding data needs to be converted to hexadecimal or binary, etc. for use by the gamma correction chip. Of course, this embodiment is not limited thereto.

[0038] In an implementation manner of this embodiment, as Figure 2 shown, before step S10 of obtaining the first output voltage data group corresponding to Gamma and VCOM in the first format, it further includes:

[0039] S01, testing the output voltage data and corresponding code encodings of the first format of Gamma and VCOM at multiple gray-scale brightness levels;

[0040] S02, fitting the calculation function according to the multiple output voltage data and the multiple code encodings.

[0041] Specifically, during multiple debugging processes, for example, testing can be performed first to obtain the output voltage data and corresponding code encodings of Gamma and VCOM in the first format at multiple gray-scale brightness levels through the testing. The output voltage data and the code encodings are in one-to-one correspondence. The calculation function is obtained by fitting based on the multiple output voltage data and the multiple code encodings, so that the corresponding code encoding can be obtained through the calculation function, avoiding obtaining data through multiple debugging and facilitating data acquisition.

[0042] In an implementation manner of this embodiment, referring to Figure 3 , before obtaining the first output voltage data group corresponding to Gamma and VCOM in the first format in step S10, it further includes:

[0043] S03, obtaining the output voltage data and corresponding code O encodings of Gamma and VCOM of multiple liquid crystal panels of the same type and size at multiple gray-scale brightness levels;

[0044] S04, obtaining multiple preliminary calculation functions by fitting based on the multiple output voltage data and the multiple code encodings of the multiple liquid crystal panels;

[0045] S05, obtaining the calculation function by fitting the multiple preliminary calculation functions.

[0046] Specifically, during multiple debugging processes, for example, testing can be performed first to obtain the output voltage data and corresponding code encodings of Gamma and VCOM of multiple liquid crystal panels of the same type and size at multiple gray-scale brightness levels through the testing. The output voltage data and the code encodings are in one-to-one correspondence, so that multiple groups of data corresponding to the multiple liquid crystal panels are obtained. The multiple groups of data are stored or input into a computer, and then the computer obtains multiple preliminary calculation functions by fitting based on the multiple output voltage data and the multiple code encodings under each liquid crystal panel, and then obtains the calculation function by fitting the multiple preliminary calculation functions, so that the corresponding code encoding can be obtained through the calculation function, avoiding obtaining data through multiple debugging and facilitating data acquisition. And by obtaining multiple preliminary calculation functions from multiple liquid crystal panels and then fitting to obtain the calculation function, the accuracy of the calculation function can be further improved.

[0047] When a customer uses a liquid crystal lamp board, it needs to be used in conjunction with a control main board. The gamma correction chip on the control main board reads the corresponding Gamma and VCOM data from the corresponding address of the memory storage chip according to the corresponding format for liquid crystal panel display, thereby improving the adaptability of the liquid crystal panel. During the process of encoding and reading the code in the memory storage chip and writing it into the gamma correction chip, there is a data verification function, which can enable the computer to calculate whether the data moved to the register of the gamma correction chip is the same as the data in the memory storage chip. Specifically, for example, the memory storage chip obtains the verification value C of the data B to be moved to the register of the gamma correction chip through algorithm A, and the gamma correction chip then obtains the verification value D of the data B that has been moved to the register of the gamma correction chip through algorithm A. This process is data verification. If C = D, it means that the data moved to the register of the gamma correction chip is complete. Of course, this embodiment is not limited thereto.
