Problems solved by technology
[0004] The disadvantage of this method is that for parts of the image that have no color cast, this compensation will affect the normal display of this part
[0005] To sum up, the current technical solution for data compensation of image color cast can only perform grayscale compensation for the entire image, which is likely to affect the liquid crystal display effect of the image area where there is no color cast.

A liquid crystal display method and device. The method comprises: determining a region with colour cast characteristics in each frame image first, and performing grey scale compensation on the region with the colour cast characteristics in each frame image, so that only the part of which colour cast will be generated in the image is compensated, and the part of which colour cast will not be generated in the image is not compensated, thereby achieving the normal display of liquid crystals.
Description
technical field [0001] The invention relates to liquid crystal display technology, in particular to a liquid crystal display method and device. Background technique [0002] Generally, there is capacitive coupling between the data line and the common line of the liquid crystal display device. During the liquid crystal display, due to the capacitive coupling effect, the common electrode of the color filter substrate will be shifted, resulting in partial color cast of the displayed image. [0003] One solution is to perform grayscale compensation on the entire image for each frame of image received, so as to avoid color cast phenomenon. [0004] The disadvantage of this method is that, for the part of the image without color cast, this compensation will affect the normal display of this part. [0005] To sum up, the current technical solution for data compensation for color cast of an image can only perform grayscale compensation for the entire image, which easily affects the...
