DISPLAY COMPENSATION METHOD, DISPLAY COMPENSATION DEVICE AND DISPLAY DEVICE

WIPO Patent Application WO/2022/160496

A1

The present invention relates to the technical field of display, and provides a display compensation method, a display compensation device and a display device, for solving the problems that the uniformity of a display screen is poor, the sub-pixel grayscale relationship is changed due to the ambient temperature change, and the brightness of the screen is influenced due to an aging offset of the threshold voltage corresponding to sub-pixels. The display compensation method is applied to the display device. The display compensation method comprises: converting a received grayscale signal into a brightness signal; performing optical compensation on the display brightness of the display device on the basis of the brightness signal; converting a corresponding brightness signal after the optical compensation into a voltage signal; and on the basis of the voltage signal, compensating for the threshold voltage corresponding to each sub-pixel in the display device, and compensating for working parameters of the display device when the display device is at different working temperatures.
