Problems solved by technology

[0003] During this process, the LCD driver IC will store and process the binary code of the RGB color. At this time, the longer the binary code representing the RGB color, the larger the storage space required, and the larger the LCD driver IC. Makes the production cost of the circuit board in the LCD increase

Embodiment Construction

[0113] The present invention converts a six-bit binary into a four-bit binary or a five-bit binary algorithm and its decompression method, divides the pixel matrix into pixel groups, and sets a reference matrix corresponding to the pixel positions in the pixel group one by one , to compress the binary color code of the pixel by judging the last two digits or the last digit and operating with the reference matrix. The following is attached Figures 1 to 7 Be specific.

[0114] like figure 1 As shown, the present invention provides a compression method of a six-bit binary color code, which is used to compress the six-bit binary color code representing the same color of each pixel in the pixel matrix, comprising the following steps:

[0115] a1. The pixel matrix is ​​divided into some first pixel groups composed of two adjacent pixels, and two pixels are respectively defined as [P1P2] according to their positions in the pixel matrix;

[0116] a2. Set two reference matrices w a...

Abstract

The invention provides the algorithm that a six-bit binary system is conversed into a four-bit six-bit binary system or a five-bit six-bit binary system and an uncompression algorithm. A pixel matrix is cut into pixel groups and reference matrixes corresponding to pixel positions in the pixel groups in a one-to-one mode are arranged, the last two bits or the last bit are or is judged to be matched with the reference matrixes for computing, and therefore the binary system color codes of pixels can be compressed. The byte length of red, green, blue (RGB) of binary codes can be shortened, storage spaces can be reduced, the size of a liquid crystal display (LCD) can be reduced, an integrated circuit (IC) can be driven beneficially, and manufacturing cost of circuit boards in the LCD can be reduced.

Description

technical field [0001] The invention relates to the field of data compression, especially the compression and decompression of binary color codes, in particular, a compression and decompression method of six-bit binary color codes used in LCD driver ICs. Background technique [0002] LCD driver ICs must be used in LCD displays at present. The principle of LCD driver IC: LCD signal scanning method is one column at a time, and goes down column by column. GateDriverIC is connected to the Gate terminal of the transistor, responsible for the switch of each row of transistors, and turns on a whole row of transistors at a time during scanning. When the transistor is turned on (ON), the SourceDriverIC can control the brightness, gray scale, and color control voltage line by line into the pixels of the Panel through the channel formed by the Source terminal and the Drain terminal of the transistor. Because GateDriverIC is responsible for the switching of each column of transistors,...
