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.

An embodiment of the invention provides a method and a device of liquid crystal display. Firstly, an area with color cast characteristics in a frame image is determined, secondly, the gray scale of the area with the color cast characteristics in the frame image is compensated, so that only portions generating color cast in the image are compensated, portions not generating color cast in the image are not compensated, and liquid crystal display is normal.
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...
