Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0036] FIG. 4 shows the structure of the liquid crystal display of the present invention. In this embodiment, a timing control unit 41 is added to the structure of the liquid crystal display shown in FIG. 3 . The timing control unit 41 generates a clock signal for controlling the second gate driver 31 . Combined with the schematic illustration of the second gate driving principle shown in FIG. 5, for the driving of n second gate lines 2GL, in the period T2 of one frame, the time for each second gate line to be gated is T1, n×T1>T2 exists, and the time t2 when each second gate line is turned on and the time t1 when the previous second gate line is turned off have a relationship of (t2-t1)<0. Preferably, please refer to the second gate driving principle shown in FIG. The following relationship exists between the times T1 at which the lines are gated: (...

Abstract

The present invention discloses a liquid crystal display device and a driving method thereof, which are more suitable for reducing the requirements of the dimension of a second gate line 2GL and the dimension of a TFT on the gate line. The technical proposal is that: regarding to the driving of n second gate lines 2GL, the gating time of each second gate line 2GL of the invention is T1 in a T2 period of one frame, and n multipliesT1is more thanT2; the gating time t2 of each second gate lines 2GL and the closing time t1 of a previous second gate line 2GL have the following relationship: (t2 minus t1) is less than 0. That is , the driving of the technical proposal of the present invention is aimed to realize n multiplies T1is more thanT2 and (t2 minus t1) is less than 0. The present invention is applied in the liquid crystal display field.

Description

technical field [0001] The invention relates to a liquid crystal display device and a driving method for a second gate line in the liquid crystal display device, in particular to a liquid crystal display device and a driving method thereof by changing a clock signal for driving the second gate line. 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] As shown in Figure 1, the liquid...
