Problems solved by technology

However, when dual-pixel video data undergoes dynamic contrast and sharpening processing, the data throughput of its corresponding processing device is often smaller than the input amount of dual-pixel video data, and the dynamic contrast and sharpening processing of the input dual-pixel video data cannot be realized.

Abstract

The invention discloses a video data conversion circuit and method and a display device, and the circuit comprises a pixel splicing module which sequentially receives each group of pixel data in each frame of image data in input video data, and is used for carrying out the pixel splicing of the received pixel data, and outputting the spliced pixel data; the data conversion module is used for carrying out data processing on the spliced pixel data so as to convert each frame of image data into first image data representing a first part of a corresponding frame of image and second image data representing a second part of the corresponding frame of image, the first part at least comprises a left half part of the frame of image, and the second part at least comprises a right half part of the frame of image; the second part at least comprises the right half part of the frame image. The method can meet the requirements of dynamic contrast and data throughput when sharpening processing is carried out on the multi-pixel video data, and can be suitable for filters of different levels.

Description

technical field [0001] The present invention relates to the technical field of video image processing, in particular to a video data conversion circuit, method and display device. Background technique [0002] With the improvement of people's demand for display image quality, the physical resolution of displays has been upgraded from SD and HD to full HD, UHD, and 8K. Therefore, the bandwidth of the HDMI or DP interface between the graphics card and the display chip is also constantly improving to meet the above requirements. [0003] Generally, the input interface of LCD (Liquid Crystal Display, liquid crystal display) video controller is HDMI or DP interface. After the input video is intercepted, it is finally output to the LCD screen through the HDMI or DP interface between the LCD video controller and the LCD screen. Generally, if the 4Kx2K resolution video is output through the Gigabit Ethernet port, nearly 20 Gigabit Ethernet cables are required to fully output the vi...
