after the display device is debugged, placing the display device on a gamma station;
and burning and compensating gray scales for the display device on the gamma station according to the gamma signal.
7. The method as claimed in claim 6, wherein the step of streaming the display device after the burning of the non-compensated gray scale is completed and obtaining the compensation signal according to the compensated gray scale and the determined data by photographing comprises:
after the uncompensated gray scale burning is finished, the display device is streamed from the gamma station to the next station, and information obtained by photographing is processed when the display device is streamed, so that brightness data are determined;
and determining a compensation signal of the display device according to the compensation gray scale, the brightness data and preset display information.
8. The compensation method for a display device according to claim 1, wherein the step of burning the compensation signal for the display device comprises:
when the display device slides to the next station, acquiring information of a compensation module of the display device;
and burning the compensation signal to the compensation module.
9. The display device compensation method of claim 1, wherein the step of acquiring the gamma signal in the display device is preceded by:
acquiring a first memory and a second memory in the display device, wherein the first memory and the second memory respectively store the compensation gray scale and the non-compensation gray scale;
and establishing connection between the first memory and the second memory and a gamma chip in the display device.
10. A display device characterized by being compensated using the display device compensation method according to any one of claims 1 to 9, the display device comprising:
the time schedule controller comprises a gamma chip;
the driving chip comprises a flash memory, and the flash memory is connected with the gamma chip and is used for transmitting gamma signals to the gamma chip;
the flash memory comprises a first partition and a second partition, the first partition stores a compensation gray scale in the gamma signal, the second partition stores an uncompensated gray scale in the gamma signal, and when the gamma chip burns the uncompensated gray scale, the display device shoots the compensation gray scale.
