Abstract

The invention discloses a compression method and device of a pixel compensation table. The method comprises the following steps: acquiring a plurality of compensation data from a pixel compensation table; converting each compensation data into a binary code to obtain a plurality of binary codes in one-to-one correspondence with the plurality of compensation data, wherein each binary code comprisesa plurality of bits; splicing the values at the same bit in the plurality of binary codes into a character string to obtain a plurality of character strings; splicing the plurality of character strings into a binary string; and performing quantization coding on the binary string to obtain a compressed pixel compensation table. According to the invention, the compression ratio can be improved, theresource occupation of the pixel compensation table is reduced, the requirement for a hardware system is reduced, and the time consumption of transmission and burning is reduced.

Description

technical field [0001] The present application relates to the technical field of display panels, in particular to a method and device for compressing a pixel compensation table. Background technique [0002] In order to eliminate the mura (display unevenness) of the display, a pixel compensation table is usually used to store the compensation information of each pixel. When projecting an image, the driver board looks up the pixel compensation table, adjusts the signal, increases the signal in the dark area of ​​the display panel, and lowers the signal in the bright area to present a uniform display effect. In the pixel compensation table, each pixel corresponds to a set of compensation information, and each set of compensation information includes one or more compensation data. The physical meaning of the compensation data depends on the algorithm, usually the adjustment value of a specific gray scale, and some algorithms set it as the voltage value to be adjusted.
