Abstract

The embodiment of the invention discloses a mura phenomenon compensation method of a display panel. The method comprises the steps of compressing an area interval with n*m pixels, and storing a preset mura compensation value corresponding to one of first pixels in each area; according to a compensation value of the preset mura, conducting linear interpolation calculation to obtain mura compensation values of other pixels except the first pixel in the same area, and conducting mura compensation on the display panel; after the display panel conducts the mura compensation, obtaining information that a mura phenomenon still exists in the Xth area, wherein the Xth area belongs to the area formed by compressing the area interval with n*m pixels of the display panel; obtaining a final gray-scale compensation curve formula; according to the preset mura compensation value and the final gray-scale compensation curve formula, calculating supplementary mura compensation values corresponding to other pixels except the first pixel in the Xth area; conducting mura compensation on the Xth area again. The embodiment of the invention further discloses the display panel. By adopting the mura phenomenon compensation method of display panel and the display panel, the mura phenomenon compensation method of the display panel has the advantages that nonuniform brightness of a picture of the display panel can be alleviated.

Description

Technical field [0001] The present invention belongs to the field of display technology, and in particular, relates to a mura phenomenon compensation method of a display panel and a display panel. Background technique [0002] Due to the flaws in the liquid crystal display (Liquid Crystal Display, LCD) manufacturing process, the brightness of the display panel of the produced liquid crystal display device is often uneven, forming various mura (mura refers to the uneven brightness of the display device, causing The phenomenon of various traces). [0003] In order to improve the brightness uniformity of the display panel (panel), there is currently a mura compensation method, that is, the mura form of grayscale images (pure white images with different brightness) is captured by an external camera, and by comparing the brightness at the center of the display panel, Calculate the brightness difference between the surrounding area and the center position, and then compensate the gray l...
