Problems solved by technology

[0005] see figure 1 , TVSOC 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 SCALERUP algorithm, and then outputs 4K2K signal to 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 has poor stability, which affects display performance. These factors restrict ultra-high resolution. The rapid popularization and cost reduction of display technology 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 sequential control drive circuits, wherein the first processing unit is used for receiving a frame of film source data, and performing data conversion on the frame of film source data, thus obtaining a frame of image data; the second processing unit is used for receiving the frame of image data, correspondingly dividing the frame of 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 N sub-piece image data; and the N sequential control drive circuits are used for receiving the N sub-piece image data, and correspondingly driving the N sub-piece display areas of a display screen based on the N sub-piece image data respectively. According to the display device and the television, a liquid crystal screen of ultrahigh resolution can be driven through a multi-channel driving technology.

Description

[0001] This application is a divisional application of the Chinese invention patent application 201310144157.7 filed on April 24, 2013 with the title of "a display device and a television set". technical field [0002] The present invention relates to the field of television technology, in particular, to a display device and a television. Background technique [0003] 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 nu...
