Problems solved by technology

[0014] The liquid crystal display is a sample-and-hold display device, and its problem is that the residual image of the previous frame produces motion blur
The advantage of this method is that the time for image data charging is guaranteed, and the disadvantage is that the cost of the second gate driver is increased, which increases the cost

Abstract

The invention discloses a liquid crystal cell matrix and a liquid crystal display device which includes the matrix. The liquid crystal cell matrix includes: a scan line which provides scanning signals; a data line which provides data signals; a common line which provides common voltage; pixel electrodes; a first thin film transistor which responds to the scanning line of a current line and a source cathode receiving the data signals; a second thin film transistor which responds to the scanning line of the current line; a third thin film transistor which responds to the scanning line in the next line and a drain is connected with the source cathode of the second thin film transistor; wherein, the data signals which provides data line for the pixel electrode of the current line via the first thin film transistor and provides common voltage for the common line of the pixel electrode of the last line via the second film transistor and the third thin film transistor. The liquid crystal cell matrix guarantees the time for filling image data and saves the cost of a second grid driver, and is applied to the field of the liquid crystal display device.

Description

technical field [0001] The present invention relates to a liquid crystal display device, in particular to a liquid crystal display device for eliminating motion blur caused by a residual image of a previous frame. Background technique [0002] Liquid crystals have the characteristics of birefringence, and under different electric fields, there will be different arrangements. Liquid crystal displays use liquid crystal light valves to control light transmittance, thereby displaying images. Existing liquid crystal display structures such as figure 1 As shown, it includes: a liquid crystal display panel 10, which has a gate driver 20 for driving the scanning line GL of the liquid crystal display panel 10; a data driver 30 for driving the data line DL of the liquid crystal display panel 10; and a timing controller 40 , for controlling the gate driver 20 and the data driver 30 . [0003] The liquid crystal display panel 10 includes a plurality of liquid crystal cell matrixes, a...
