Problems solved by technology

[0004] see figure 1 , TV SOC chip (TV display processing chip 102) generates FHD signal and outputs it to FRC chip 104, FRC chip 104 expands FHD image data to 4K2K image data through built-in SCALER UP algorithm, and then outputs 4K2K signal to ultra-high resolution The dedicated TCON chip (timing control drive circuit 106) at the display 108 end, because the dedicated TCON chip requires powerful processing capabilities, high process requirements, and complex structure, it is difficult to manufacture, and its stability is poor, which affects the display performance. These factors restrict ultra-high The rapid popularization and cost reduction of resolution display technologies such as 4K2K technology

Abstract

The invention provides a display device and a television. The display device comprises a first processing unit, a second processing unit and N time sequence control driving circuits, wherein the first processing unit is used for receiving frame film source data, conducting data conversion on the frame film source data, and obtaining frame image data, the second processing unit is used for receiving the frame image data, correspondingly dividing the frame image data into N sub-piece image data according to a pixel proportion occupied by each sub-piece display area of N sub-piece display areas, and outputting the N sub-piece image data, and the N time sequence control driving circuits are used for receiving the N sub-piece image data, and correspondingly driving N sup-piece displaying areas of a display screen base on the N sub-piece image data. The display device can drive a liquid crystal screen of ultrahigh resolution through a multi-channel driving technology.

Description

technical field [0001] The present invention relates to the field of television technology, in particular, to a display device and a television. Background technique [0002] In recent years, with the rapid development of display technology, from CRT (Cathode Ray Tube) to LCD (liquid crystal display) technology, from CCFL backlight to energy-saving and thin LED products, from 2D to 3D technology products, every new display technology Updating and updating are all to make the display technology have higher performance. At present, the application of ultra-high-resolution display screens has become a research hotspot. Ultra-high-resolution display screens, such as 4K×2K, have achieved four times the resolution of the current full HD pixel 1080p, reaching a resolution of 3840×2160. Calculated by the number of pixels, the 1080p picture has a total of 1920×1080=2073600 pixels, while the “4K×2K” pixel information is 3840×2160=8294400 or 4096×2160=8847360. The latter two are basi...
