Abstract

The invention discloses a compensation gray-scale value determination method, a compensation method, a compensation device, equipment and a medium. The method comprises the steps of collecting brightness values of a mura area and a non-mura area of a display panel under a plurality of binding points; fitting a first gamma curve corresponding to the mura area according to the brightness values of the mura area under the plurality of binding points; according to the brightness value of the non-mura area under the target binding point and the first gamma curve, determining the corresponding compensation gray scale value of the mura area under the target binding point, wherein the target binding point is any binding point in the multiple binding points. According to the embodiment of the invention, the problem of compensation of a large-area mura region can be solved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to a method for determining a compensated gray scale value, a compensation method, a device, a device and a medium. Background technique [0002] During the display process of the display panel, a mura phenomenon (mura refers to uneven display of the display panel) may occur, which affects the display effect of the display panel. In order to avoid the mura phenomenon, Demura compensation can be performed on the display panel. [0003] In the related art, when performing Demura compensation on the display panel, the display panel is divided into multiple blocks, and the average brightness value in the block is used as the target brightness value of each pixel in the block, so as to determine the brightness of each pixel in the block. The compensation grayscale value corresponding to the pixel. However, when the area of ​​the divided block is smaller than the actual a...
