A display device and a television

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 update has given Bringing higher performance to display technology. 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 basically 4 times that...

Problems solved by technology

[0004] see figure 1 , the TVSOC chip (TV display processing chip 102 ) generates a signal of FHD specification and outputs it to the FRC chip 104 , and the FRC chip 104 expands the FHD image data to 4K2K image data through the built-in SCALERUP algorithm, and then outputs the 4K2K signal to the ultra-high resolution display 108 The dedicated TCON chip (timing control drive circuit 106) at the 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 display performance. These factors restrict ultra-high resolution. The rapid popularization and cost reduction of display technology such as 4K2K technology
