Liquid crystal display device, scan driver, and display driving method

Abstract

The invention discloses a liquid crystal display device, a scan driver and a driving display method. The liquid crystal display device comprises a scan driver, a data driver and a liquid crystal display panel. The scan driver comprises a plurality of cascaded shift registers. Each shift register includes an input end, an output end and a sequence signal control end. The input end of shift register in the first stage is used for receiving a start signal STV. The output end of the shift register in the 2n-1-th stage is connected with the input end of the shift register in the 2n-th stage and is further connected with a scanning line in the n-th row, where n is a natural number. The data driver outputs a black data driving signal to a data line when the shift register in the first stage receives another start signal STV via the input end at an interval of the number of 2N+1 sequence signals CKV, where N is a natural number. In this way, the invention can reduce the retention time of an image on a screen, reduce the impact on human eyes' persistence of vision, and improve motion blur.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a liquid crystal display device, a scan driver and a display driving method. Background technique [0002] In the era of rapid technological development, liquid crystal displays have become widely used in electronic display products, such as televisions, computer screens, and mobile phones. The existing liquid crystal display includes a data driver, a scan driver and a liquid crystal display panel, wherein the liquid crystal display panel has a pixel array, and the scan driver is used to sequentially turn on corresponding pixel columns in the pixel array, so that the pixels output by the data driver The data is sent to the pixels, and then the picture to be displayed is displayed. [0003] Current technologies mostly use shift registers to implement scan drivers that can sequentially turn on corresponding pixel columns in the pixel array. Please refer to figure 1 and fi...

[0004] However, although the image of the liquid crystal display panel will change when the next frame of image signal arrives, due to the phenomenon of persistence of vision in the human eye, when the next frame of image is updated, the memory of the previous frame is still retained, which will cause Issues with viewers seeing blurry images
