Problems solved by technology

[0003] Taking the current three resolutions of HD (High Definition, high definition), FHD (Full High Definition, full high definition) and UHD (Ultra High Definition, ultra high definition) as an example, the SRAM capacity occupied by the over driver without considering the compression is 26Mbit, 50Mbit, 200Mbit, which account for a large proportion of the entire chip design, so the current industry generally uses data compression technology in the design of over driver, which can greatly save the capacity of SRAM. Take the triple compression commonly used in the industry as an example , the SRAM can be reduced to one-third of the original, and the SRAM capacity required by HD / FHD / UHD TCON (TimingController) is reduced to 8.7Mbit / 16.7Mbit / 66.7Mbit, but the over driver still occupies a large amount of SRAM, which affects timing The cost of the controller has a big impact

Abstract

The invention provides a data processing method and a data processing system. The data processing method comprises the following steps: converting data from an RGB format to a YUV format; Compressingthe data in the YUV format according to a certain proportion; Comparing the pixel points with surrounding pixel points one by one, and replacing the data of the current pixel point with the directionnumber of the surrounding pixel point closest to the data of the current pixel point. a plurality of pixel points around the current pixel point are numbered, the data of the current pixel point is compared with the data of the numbered pixel point, and if the data difference value between the numbered pixel point and the current pixel point is smaller than a threshold value, the corresponding number is quoted to serve as the compressed data of the current pixel point.

Description

technical field [0001] The present application relates to a data processing method and a data processing system, in particular to a data processing method and a data processing system in the field of display. Background technique [0002] In the over driver (overvoltage drive, OD) of the display device, the size of the SRAM (Static Random-Access Memory, Static Random-Access Memory) has a great influence on the cost of the timing controller. In the current design of the timing controller, the over The driver needs to store the entire data of the previous frame. The current frame queries the lookup table based on the data of the previous frame and the current frame to determine the final output data. Therefore, the over driver is the module that occupies the most SRAM. [0003] Taking the current three resolutions of HD (High Definition, high definition), FHD (Full High Definition, full high definition) and UHD (Ultra High Definition, ultra high definition) as an example, the ...
