Abstract

The present invention provides a display data compression method. The method comprises: providing a pixel data line; determining whether there is a pixel value set in the pixel data, wherein the pixel value set includes continuously arranged pixel values consisting of a first pixel value, and the differences between each pixel value located behind the first pixel value in the pixel value set and the first pixel value are not larger than a first threshold; if there is the pixel value set, performing quantification of the sum of the differences between each pixel value set and the first pixel value, and obtaining a quantification value; determining whether the quantification value is larger than a second threshold or not; and if the threshold value is not larger than the second threshold, setting each pixel value as the first pixel value. The display data compression method and the display data processing system can effectively compress the pixel data so as to improve the display data sending/receiving speed and reduce the read/write delay.

Description

technical field [0001] The invention relates to image data compression technology, in particular to a display data compression method and a display data processing system. Background technique [0002] An image may be stored in a display device as information on a plurality of pixels. For example, an image may be divided into a plurality of pixels arranged in a matrix, and information on each of the pixels may include information on color and brightness of the pixel. For example, information about one pixel may be divided into grayscale components of red, green, and blue. Also, in monochrome display, information about one pixel may not be divided according to color, but may contain gray scale information. [0003] Existing compression methods include a variety. Common lossless compression methods include run-length compression and LZ77 compression. Common lossy compression methods include JPEG compression. [0004] Run-length compression is a compression technique that ...
