Specifically, the R/G/B cut-off voltage is adjusted by controlling the Offset parameters corresponding to the three colors of R, G, and B:

When the screen is obviously reddish when displaying a black image, adjust the red cut-off voltage by adjusting the parameter of R Offset to improve the reddishness of the black image.

When the screen is obviously greenish when displaying a black image, adjust the cut-off voltage of red by adjusting the parameters of G Offset to improve the problem of greenishness of black image.

If the current value of the R/G/B three-color Gain register, the current value of the R/G/B three-color Offset register, the current value of the x chromaticity coordinate and the current value of the y chromaticity coordinate all fall within the white balance debugging parameters If the real-time color display status of the display device to be debugged conforms to the corresponding white balance debugging parameters, it is determined that the white balance debugging device of the display device to be debugged operates normally, and the white balance debugging is completed. The display device to be debugged is moved to the next station by the conveying device, and the next factory inspection is carried out.
