Abstract

The invention discloses a gray scale compensation method and a gray scale compensation device of a display panel. The display panel includes a plurality of pixels, the display panel includes a multi-level area, and the compensation method for the gray scale of the display panel includes: S1, determining the area of ​​the current level; Gray scale compensation for the above pixels; S3, determine the area of ​​the next level according to the area of ​​the current level, wherein the pixels located in the area of ​​the current level and the part of the pixels located in the area of ​​the next level Repeat; S4, performing grayscale compensation on the plurality of pixels located in the region of the next level. The gray scale compensation method of the display panel of the present invention can effectively solve the factor of separation of regions at different levels caused by the traditional gray scale compensation algorithm, so that the gray scale of the compensated picture pixels is smoother without obvious sense of boundary.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a gray scale compensation method and a gray scale compensation device of a display panel. Background technique [0002] Mura (mura refers to the phenomenon that the brightness of the display device is uneven, resulting in various traces) is the difference in the visual perception of different colors, especially in the pure color grayscale screen, the mura is extremely obvious. Mura on the TFT-LCD display panel is mainly caused by uneven backlight and process factors, such as CF process, TFT process, CELL process, etc., so that even in the split-screen area of ​​the same CELL, the degree of Mura in the upper, middle and lower is also different. the same. In order to improve the uniformity of the brightness of the display panel, there is currently a mura compensation method, that is, the mura form of the grayscale picture (pure white picture with different brightness) is ...
