METHOD AND DISLAY DEVICE FOR UNIFORM IMAGE DISPLAY

摘要

A method and a display device for uniform image display are provided. The method is used for a full in-cell display device and includes steps of: a display device inputting a first image signal, compensating the first image signal according to image compensation data to obtain a third image signal and displaying the third image signal. The display device includes a color filter substrate, an array substrate and a liquid crystal layer disposed therebetween. A side of the array substrate facing toward the liquid crystal layer is disposed touch electrodes. The touch electrodes are combined with common electrodes of the array substrate and arranged on the array substrate in a matrix. The compensation data are common electrode voltage offsets determined according to differences between grayscale information of the first image signal and an original second image signal. Accordingly, the invention can effectively improve the displayed image uniformity.
