Abstract

The present invention provides a method for storing a compensation table of a display panel, which includes obtaining the multi-grayscale compensation tables of the first sub-pixel, the second sub-pixel, and the third sub-pixel of the display panel respectively; The original gray scale and compensation value corresponding to the same coordinate position between the compensation tables are fitted according to the unary n(n≥1) function relationship to obtain the first combinable coefficient and the first non-combinable coefficients, and record all first combinable coefficients in the first coefficient table, and record all first non-combinable coefficients in the second coefficient table; the fitting process of the second sub-pixel and the third sub-pixel and the first One sub-pixel coincides. The amount of information in the compensation table is reduced by fitting different sub-pixels according to the unary n(n≥1) function relationship.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for storing a compensation table of a display panel. Background technique [0002] At present, in the production process of display panels, due to the production process and other reasons, Mura (uneven brightness) often occurs, and bright or dark spots appear, resulting in a decrease in the display quality of the panel. In order to eliminate the Mura of the display panel, a compensation table is usually used to store the compensation information of each pixel. When projecting images, the driver board looks up the compensation table, adjusts the signal, increases the signal in the dark area of ​​the panel, and lowers the signal in the bright area to present a uniform display effect. In the compensation table, each pixel corresponds to a set of compensation information, and each set of compensation information contains one or more compensation data. The physical meaning...
