Problems solved by technology

The compensation table occupies a large amount of system storage space, and the process of transmitting and programming data on the production line consumes a lot of time, which reduces the operating speed and production efficiency of the display device
[0004] The existing practice is to perform transformation on multiple lines of the compensation table, where the basic unit of transformation and encoding is the compensation data of multiple lines of pixels, and at least multiple line buffers are required for hardware design to cache multiple lines data, so that the cost of hardware has increased significantly, which is contrary to the original intention of the algorithm to reduce costs
In addition, if the size of the transformation block is reduced blindly, such as changing the number of lines from 8 to 4, the compression effect will be reduced

Abstract

A compression method for a display system, comprising the following steps: step S10, providing a compensation table; step S20, rearranging a row of pixel data in the compensation table; step S30, dividing the row of pixel data after the rearranged data into multiple transformation blocks, each of which is adjacent to each other and does not overlap each other; and step S40, performing a transformation procedure on each of the transformation blocks, and then quantizing and encoding to obtain the compressed data of the row. In this way, while ensuring the compression effect, the hardware cost of the compression algorithm can also be reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a compression method for a display system. Background technique [0002] During the production process of the display panel, Mura (unevenness / brightness unevenness), such as bright spots or dark spots, often occurs due to the production process and other reasons, resulting in a decrease in the display quality of the panel. In order to eliminate the Mura of the display device, the prior art usually uses a compensation table to store the compensation information of each pixel in the display device. When projecting a picture, the driver board in the display device will look up the compensation table, adjust the signal, increase the signal in the dark area of ​​the display panel, and lower the signal in the bright area, so as to present a uniform display effect. In the compensation table, each pixel corresponds to a set of compensation information, and each set of compensation info...
