Abstract

The embodiment of the present invention discloses a method for compensating the mura phenomenon of a display panel, including: performing compression at an interval of n*m pixels, and storing a preset mura compensation value corresponding to one of the first pixels in each area; according to the Preset the mura compensation value to perform linear interpolation calculation to obtain the mura compensation value of other pixels except the first pixel in the same area, and perform mura compensation on the display panel; after the mura compensation is performed on the display panel, the mura phenomenon still exists in the Xth area is obtained Information, wherein the Xth area belongs to the area formed by the compression of the display panel at an interval of n*m pixels; obtain the final gray scale compensation curve formula; calculate according to the preset mura compensation value and the final gray scale compensation curve formula Obtain the supplementary mura compensation values ​​corresponding to other pixels in the Xth area except the first pixel; perform mura compensation on the Xth area again. The embodiment of the invention also discloses a display panel. Adopting the present invention has the advantage of reducing the brightness unevenness of the screen of the display panel.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a method for compensating a mura phenomenon of a display panel and the display panel. Background technique [0002] Due to defects 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, resulting in various trace phenomena). [0003] In order to improve the uniformity of the brightness of the display panel (panel), there is currently a mura compensation method, that is, the mura form of the grayscale picture (pure white picture with different brightness) is captured by an external camera, and by comparing the brightness at the center of the display panel, Calculate the difference between the brightness of the surrounding area and the center position, and then r...
