Problems solved by technology

[0003] At present, the industry mainly uses color demura (color compensation) technology to improve in-plane color shift. This technology is similar to demura (brightness compensation). The difference is that demura technology is aimed at uneven brightness. Inhomogeneity, color demura integrates the algorithm in the IC, and adjusts the gray scale of the screen displayed in different areas, so as to improve the color uniformity. Although the above method can effectively improve the color cast in the plane, it requires additional IC cost

Abstract

The invention discloses a pixel array. The pixel array comprises a plurality of pixel units, each pixel unit comprises the sub-pixels of various colors, the sub-pixels of various colors comprise the blue sub-pixels, and the proportion of the blue sub-pixels in the pixel array is larger than that of the rest sub-pixels of various colors in the pixel array. According to the present invention, the gray scale value of the blue sub-pixels during white balance correction is increased by increasing the proportion of the blue sub-pixels in the pixel array, so that the color uniformity is improved, thetechnical problem of color cast in the surface of the display panel is effectively solved, and the display effect of the display device is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a pixel array. Background technique [0002] In-plane color shift is an important parameter for evaluating panel quality, and it refers to an important indicator of the uniformity of colors displayed in different areas in grayscale images. Therefore, how to improve color uniformity and make the in-plane color shift as small as possible, It is an unavoidable problem for every panel manufacturer. [0003] At present, the industry mainly uses color demura (color compensation) technology to improve in-plane color shift. This technology is similar to demura (brightness compensation). The difference is that demura technology is aimed at uneven brightness. Inhomogeneity, color demura integrates the algorithm in the IC, and adjusts the gray scale of the screen displayed in different areas, so as to improve the color uniformity. Although the above method can effectively improve ...
