Method for treating video of liquid crystal display device

Abstract

The invention discloses a method for treating a video of a liquid crystal display device, and in the method, interleaving and frame erasure techniques are utilized to lower the video image moving velocity so as to efficiently reduce the streaking phenomenon of the liquid crystal display device. The method comprises the following steps: 1) receiving and caching a to-be-displayed video signal; 2) estimating the motion of a continuous two-frame video and dividing a continuous three-frame video into a video with a smaller motion frame, a video with a proper motion frame and a video with a bigger motion frame; 3) performing frame erasure treatment on the video with the smaller motion frame, eliminating the middle frame of the continuous three-frame video, performing no treatment on the video with the proper motion frame, and performing interleaving treatment on the video with the bigger motion frame by using the interleaving technique based on bidirectional motion estimation and the motion compensation; and 4) finishing integrating the interleaved video and the frame-erased video with the original video and keeping a frame rate of the output video signal equal to the frame rate of the received video signal. The method is suitable for the current mainstream 50Hz / 60Hz liquid crystal display device as well as high-class liquid crystal display devices, such as the 100Hz / 120Hz / 200Hz / 240Hz liquid crystal display devices, and the like.

Description

technical field [0001] The invention relates to a video processing method, in particular to a video processing technology aimed at the trailing phenomenon of a liquid crystal display device. Background technique [0002] Liquid crystal display (LCD) is the fastest-growing technology in flat panel display technology. With the smooth resolution of problems such as brightness, contrast and viewing angle, its advantages of rich colors have been fully utilized. The display effect of static images and text On the one hand, it has caught up with or even surpassed the display effect of mature CRT, and its application has been greatly promoted. In recent years, the large-scale LCD panels used in PCs and TVs are rapidly developing. At present, LCD panel manufacturers are actively improving the dynamic image quality. There is still a difficult defect in LCD display of moving images and texts. It's the tailing issue. [0003] Studies in recent years have shown that there are four main...
