Embodiment 1

[0032] figure 2 A schematic structural diagram of a liquid crystal display according to Embodiment 1 of the present invention is shown; image 3 for correspondence figure 2 The schematic diagram of the drive.

[0033] See figure 2 and image 3 , on the basis of the existing liquid crystal display structure, a pTFT is added to the Cs electrode of the liquid crystal cell part as a second TFT, the gate and source of the second TFT are connected to the Cs electrode line, and the drain is connected to the Cs capacitor. Its driving principle is as image 3 As shown, within the time T of one frame, the GL in the liquid crystal cell is gated by the VGH pulse output by the gate driver 12 at time t1. At this time, the data signal on DL charges Clc, and when the voltage on GL changes When it is VGL, the TFT on GL is turned off, and the voltage difference across Clc is maintained by the Cs capacitor; therefore, from t1 to t2, the liquid crystal unit displays the gray scale require...

Embodiment 2

[0035] Figure 4 A schematic structural diagram of a liquid crystal display according to Embodiment 2 of the present invention is shown; Figure 5 yes Figure 4 Schematic diagram of the drive for the illustrated embodiment.

[0036] See Figure 4 and Figure 5 , on the basis of the existing liquid crystal display structure, an nTFT is added to the Cs electrode of the liquid crystal cell part as a second TFT, the gate and source of the second TFT are connected to the Cs electrode line, and the drain is connected to the Cs capacitor. Its driving principle is as Figure 5 As shown, within the time T of one frame, the GL in the liquid crystal cell is gated by the VGH pulse output by the gate driver 12 at time t1. At this time, the data signal on DL charges Clc, and when the voltage on GL changes When it is VGL, the TFT on GL is turned off, and the voltage difference across Clc is maintained by the Cs capacitor; therefore, from t1 to t2, the liquid crystal unit displays the gr...

Embodiment 3

[0038] Figure 6 It is a structural schematic diagram of a liquid crystal display according to Embodiment 3 of the present invention.

[0039] See Figure 6 , on the basis of the existing liquid crystal display structure, an nTFT is added to the Cs electrode of the liquid crystal cell part as the second TFT, the gate and source of the second TFT are connected to the Cs electrode line, the drain is connected to the Cs capacitor, and the gate The pole line GL and the Cs electrode line are driven by a dual gate driver 22 . In Embodiment 2, the gate line GL is driven by a gate driver, and the Cs electrode line is driven by a Cs electrode driver; Figure 5 It can be seen from the driving principle of the gate line and the Cs electrode line that the driving of the gate line and the Cs electrode line is also a second-order drive; therefore, in this embodiment, the gate driver and the Cs electrode in Embodiment 2 are further integrated driver is a dual gate driver 22, i.e. Figure...

Abstract

The invention discloses a liquid display device, which adds a second thin film transistor for the Cs electrode of each liquid crystal unit on the configuration of an existing liquid display device, and controls the image data charged by a pixel electrode and a fixed gate voltage respectively through a first thin film transistor and the second thin film transistor. Thus, the liquid display device not only can effectively eliminate the foggy moving phenomenon generated by the residual image of the last frame, but also does not shorten the time of the pixel electrode charging image data. The liquid display device is also applicable to a normally white LCD or a normally black LCD.

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 crystal display (LCD) uses the change of the electric field strength clamped on the liquid crystal molecules to change the orientation of the liquid crystal molecules to control the intensity of light transmission to display images. Currently, liquid crystal displays have been widely used in various terminal display devices of large, medium and small sizes due to their characteristics of light weight, small volume, and thin thickness. Generally, a liquid crystal display includes a liquid crystal display panel having a matrix of pixels and a driving circuit for driving the liquid crystal display panel. [0003] like figure 1 As shown, the liquid crystal display includes: a liquid crystal display panel 11, which has a pixel ma...
