s2, debugging the display device according to the gamma signal;
s3, when the display device is debugged, burning compensation gray scales for the display device according to the gamma signals;
s4, when the compensation gray scale burning is completed, burning the uncompensated gray scale to the display device according to the gamma signal, and lighting the display device by using the compensation gray scale to take a picture;
s5, streaming is carried out on the display device after the non-compensation gray scale burning is completed, and a compensation signal is obtained according to the compensation gray scale and the data determined by photographing;
s6, burning the compensation signal for the display device.
According to the display device compensation method, gamma signals are divided into compensation gray scales and non-compensation gray scales, the compensation gray scales are firstly burnt and then the non-compensation gray scales are burnt, so that when the non-compensation gray scales are burnt, the process of shooting by using the compensation gray scales to lighten the display device can be synchronously carried out, the time of the data burning and processing process of the display device is shortened, and the time of the data burning and processing process of the display device is further shortened by carrying out data processing when the display device performs streaming, and the efficiency of the compensation process of the display device is improved.
Note that the compensation gray scale refers to a gray scale for determining a compensation signal of the display device, and the non-compensation gray scale refers to other gray scales except for the compensation gray scale in the gray scale for driving the display device, for example, the gamma signal includes gray scales of 0, 3, 5, 7, 13, 25, 60, 75, 128, 225, 255, etc., and the compensation gray scale is 25, 60, 128 gray scales, and the non-compensation gray scale is 0, 3, 5, 7, 13, 75, 225, 255 gray scales.
In one embodiment, before the step of acquiring the gamma signal in the display device, further comprising:
obtaining the maximum gray scale of the display device;
determining the compensation gray scale of the display device according to the maximum gray scale of the display device and the compensation strategy;
and determining the uncompensated gray scale of the display device according to the compensated gray scale of the display device. By determining the compensation gray scale and the non-compensation gray scale of the display device before the gamma signal of the display device is acquired, the compensation gray scale and the non-compensation gray scale can be respectively burnt when the gamma signal is burnt, a plurality of processes are correspondingly carried out at the same time, and the burning and processing time of data is shortened.
Specifically, when determining the compensation gray scale of the display device, it is first required to determine the maximum gray scale of the display device, for example, whether the display device is in a 256 gray scale driving mode or a 128 gray scale driving mode, then determine the compensation strategy of the display device, for example, whether to determine the compensation signal of each gray scale according to the brightness difference of a part of gray scales, or to divide the gray scales into a high gray scale and a low gray scale, respectively determine the compensation signal, respectively compensate the high gray scale and the low gray scale, then determine the compensation gray scale from the gamma signal correspondingly, and then determine the non-compensation gray scale correspondingly after determining the compensation gray scale.

After the uncompensated gray scale is determined, the uncompensated gray scale is burnt into the second partition according to the connection of the gamma chip and the second partition, and at the moment, the compensated gray scale is burnt completely, and the first partition and the second partition are connected with the gamma chip, so that photographing of the display device can be performed at the moment, namely, the two can be performed simultaneously, and when the two are performed, the next process is continued after one of the two is completed.
Specifically, since the first partition and the second partition are two different areas, data can be transmitted to the gamma chip respectively or instructions or data transmitted by the gamma chip can be received respectively, after the compensation gray scale is burnt in advance, the compensation gray scale can be extracted from the first partition at this time, meanwhile, since the first partition and the second partition are arranged separately, the uncompensated gray scale can be burnt in the second partition, and then the burning of the uncompensated gray scale and the photographing of the compensation gray scale lighting display device can be carried out at the same time, namely, two separate processes are carried out at the same time, so that the burning and photographing time of the data of the display device can be shortened.
Specifically, since the writing of the non-compensation gray scale and the photographing of the compensation gray scale lighting display device are performed simultaneously, the first completed process can be determined according to the time length of the two processes, and then after one of the processes is completed, the next process is continued, so that the writing of the non-compensation gray scale and the photographing of the compensation gray scale lighting display device are completed.
