Problems solved by technology

[0003] At present, the compensation table is usually compressed by using a common general-purpose encoder directly. Since different encoding tools in the encoder have different degrees of influence on the encoding performance of the compensation table, the compression ratio of the compensation table and the The time complexity of encoding cannot meet the actual needs

Abstract

Provided is a compensation table compression method. Each coding block is processed by using multiple prediction modes, and a prediction mode with the minimum rate distortion optimization value in each coding block is selected as an optimal prediction mode through a rate distortion optimization method, so that each coding block can correspond to an optimal prediction mode, and the compression rateof the compensation table and the time complexity of coding are reduced, and further the compression quality is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a compensation table compression method. Background technique [0002] In the prior art, in order to eliminate the uneven brightness of the display panel, a compensation table is usually used to store the compensation information of each pixel in the display panel, thereby eliminating the uneven brightness and phenomenon of the display panel, thereby improving the display quality of the display panel . In order to improve data transmission efficiency, the compensation table needs to be compressed. [0003] At present, the compensation table is usually compressed by using a common general-purpose encoder directly. Since different encoding tools in the encoder have different degrees of influence on the encoding performance of the compensation table, the compression ratio of the compensation table and the The time complexity of encoding cannot meet the actual needs.
