Display compensation method, display compensation device and display device

Abstract

The invention provides a display compensation method, a display compensation device and a display device, and relates to the technical field of display. While the display precision is guaranteed and the cost is reduced, the problems that the uniformity of a display screen is poor, the sub-pixel gray scale relation is changed due to the change of the environment temperature, and the brightness of the screen is influenced due to the aging offset of the threshold voltage corresponding to the sub-pixels are solved. The display compensation method is applied to the display device. The display compensation method comprises the following steps: converting a received gray-scale signal into a brightness signal; performing optical compensation on the display brightness of the display device based on the brightness signal; converting the corresponding brightness signal after optical compensation into a voltage signal; based on the voltage signal, compensating threshold voltage corresponding to each sub-pixel in the display device; and compensating for the working parameters of the display device when the display device is at different working temperatures.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display compensation method, a display compensation device, and a display device. Background technique [0002] A high-resolution organic light-emitting diode (English: Organic Light-Emitting Diode, hereinafter referred to as: OLED) display screen is one of the key points of competition in the screen display industry at this stage. While the OLED display is self-illuminating, there will be problems such as poor screen uniformity, environmental temperature changes that change the gray scale relationship of sub-pixels, and aging shifts of threshold voltages corresponding to sub-pixels that affect screen brightness. At present, the compensation display scheme for OLED display is mainly aimed at large-size OLED display, and the compensation consideration is not comprehensive, resulting in the final display accuracy to be improved, and the non-self-developed technology has ...
