Abstract

The invention discloses a method for acquiring a gray-scale compensation value of a pixel and belongs to the technical field of display. According to the method, the size of a storage space in an Mura processing structure is reduced. The method for acquiring the gray-scale compensation value of the pixel comprises the following steps: acquiring a display area of a display panel; averagely dividing the display area into a plurality of first subareas according to a first preset rule, wherein each first subarea at least comprises two pixels; acquiring a prestored multinomial coefficient of each first subarea; constructing a multinomial corresponding to each first subarea according to a second preset rule; acquiring a preset value range for an independent variable of the multinomial, and acquiring the gray-scale compensation value of each first subarea according to the corresponding multinomial. The method disclosed by the invention can be used for display devices of a liquid crystal television, a liquid crystal display, a mobile phone, a tablet computer and the like.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a method for acquiring grayscale compensation values ​​of pixels. Background technique [0002] In the process of manufacturing the display panel, defects (mura) such as dots, lines, bands, and blocks may appear on the panel due to insufficient manufacturing process or materials during the production process of the display panel. Grayscale compensation can be performed by adjusting the external circuit voltage to improve some defects; or grayscale compensation can be performed through the Mura treatment structure in the back-end process to improve such defects, thereby improving the yield rate of the display panel. [0003] In the Mura processing structure, the gray-scale compensation value corresponding to the defect can be obtained through image processing, and then each gray-scale compensation value is stored in the Mura processing structure, which is directly called ...
