Problems solved by technology

[0005] However, due to the design structure of the above-mentioned double-gate transistors, the common voltage (Vcom) is susceptible to coupling (couple), and because the charging time is halved, the time for Vcom to restore the original voltage level is also halved. This will cause picture quality problems of cross-talk in the horizontal direction

Embodiment Construction

[0015] In order to avoid image quality problems caused by crosstalk in the horizontal direction, it is necessary to speed up the time for the common voltage (Vcom) to return to the level. Therefore, the present invention adopts a method of reducing the resistance of the common voltage wiring to speed up the time for the common voltage to return to the level.

[0016] see image 3 Schematic diagram of the structure and Figure 4 As shown in the figure, the double-gate transistor substrate 20 of the liquid crystal display proposed by the present invention includes a plurality of data lines 22, a plurality of scanning lines 24, a multi-pixel unit 26 and a plurality of dummy data lines ( dummy data line)38. The pixel units in the first column use scanning lines G1 and G2, the pixel units in the second column use scanning lines G3 and G4, the pixel units in the third column use scanning lines G5 and G6, and so on; and the scanning lines G1, G2 and G3 , G4... etc. are connected to...

Abstract

The invention provides a base plate of a double gate electrode transistor of a liquid crystal display. Dummy data lines are arranged among adjoining data lines and among each group of adjoining pixel units; and all the dummy data lines are connected to a common voltage electrode running cable. Therefore, the base plate of the double gate transistor of the liquid crystal display can effectively reduce the resistance of the common voltage and shorten the recovery time and the alignment time of the common voltage, so as to solve the problem that the picture quality is easily crossly interfered in the horizontal direction in the prior art.

Description

【Technical field】 [0001] The invention relates to a liquid crystal display device with a double gate design, in particular to a double gate transistor substrate of a liquid crystal display. 【Background technique】 [0002] In thin film transistor liquid crystal display (TFT LCD), the driver IC used is divided into source driver IC (Source IC) and gate driver IC (Gate IC) according to the X and Y axes, in order to utilize the timing controller (Time Controller) ) The data signal from the source driver IC provides the grayscale voltage according to the signal, and the on or off of the thin film transistor is controlled by the gate driver IC. [0003] In order to reduce the area of ​​the control circuit, the design of double-gate transistors was derived, which halved the number of data lines and doubled the number of scanning lines to achieve the effect of reducing the number of overall source ICs and their channels. For example, a general liquid crystal display is 800×RGB×480,...
