Abstract

The invention discloses a compensation table compression method, display manufacturing equipment and a device with a storage function. The method comprises the steps of obtaining a reference frame compensation table and a current frame compensation table; dividing the reference frame compensation table and the current frame compensation table into a plurality of coding blocks, and processing eachcoding block by using a plurality of prediction modes to obtain a residual coding block corresponding to the corresponding prediction mode; and compressing the residual encoding block. By means of themode, resources can be saved, the cost is reduced, and the working efficiency is improved.

Description

technical field [0001] The present application relates to the display field, in particular to a compensation table compression method, a display manufacturing device and a device with a storage function. Background technique [0002] In order to eliminate the Mura of the display, 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 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. [0003] The size of the compe...
