Problems solved by technology

However, the number of pixel common electrodes required by this solution is large, and the pixel common electrodes are arranged in the pixel area, so it will have a negative impact on the pixel area, so that the aperture ratio of the pixel is greatly affected, and the resolution of the TFT-LCD is relatively low. Low

Embodiment Construction

[0014] In the prior art, the gate signal of each row is simultaneously transmitted by the gate line of the row and the pixel common electrode of the next row, the number of common electrodes required is relatively large, and the common electrodes are arranged inside the pixel area, so there will be no The bad effect of the pixel area causes the aperture ratio of the pixel to be greatly limited, which in turn makes the resolution of the TFT-LCD lower. Different thin film transistors connect the two ends of the gate signal line to the provided lead wires. For each row of gate signal lines formed on the array substrate, the gate signal can pass through the row of gate signal lines and connect with the row of gate signals. The leads connected to the signal lines are conducted at the same time, and the gate signal of each row is conducted at least by the gate signal line and the set lead at the same time, which reduces the gate resistance, improves the conduction speed of the gate s...

Abstract

The invention discloses an array substrate and a liquid crystal display, which can better improve the aperture opening ratio of pixels and further promote the resolution of a TFT-LCD (Thin Film Transistor-Liquid Crystal Display). The array substrate comprises a pixel zone arranged on a substrate and at least two leads arranged at the periphery of the pixel zone and used for transmitting grid signals, wherein each lead is connected with two ends of each corresponding grid signal wire, close to the periphery of the pixel zone, through a first TFT and a second TFT.

Description

technical field [0001] The present invention relates to the technical field of thin film transistor liquid crystal display (TFT-LCD, Thin Film Transistor Liquid Crystal Display), in particular to an array substrate and a liquid crystal display. Background technique [0002] TFT-LCD has the characteristics of small size, low power consumption, and no radiation. It has developed rapidly in recent years, and its size is getting larger and larger, and its display effect is getting better and better. [0003] like figure 1 The schematic diagram of the structural composition of the TFT-LCD driving device is shown. On the array substrate, gate signal lines 101 and data signal lines 102 are formed. The gate signal line 101 and the data signal line 102 are connected through a thin film transistor 103 . Under this structure, the gate signal of each row is transmitted by one gate line, especially in a large-size liquid crystal display device, the signal will be delayed during the tra...
