Abstract

The invention provides a signal wiring structure in a GOA (gate driver on array) circuit of a liquid crystal display. The structure comprises a plurality of first metal layers, an insulating layer and a plurality of second metal layers, wherein each first metal layer is provided with a control signal wire; the insulating layer is formed under the first metal layers; the plurality of second metal layers are formed under the insulating layer, and the control signal wire on each first metal layer is electrically connected with the corresponding second metal layer through a plurality of through holes; and the number of the through holes formed on the control signal wire on each first metal layer is the same. According to the signal wiring structure, the control signal wire on each first metal layer is electrically connected with the second metal layer through a plurality of through holes, and the number of the through holes formed on the control signal wire on each first metal layer is the same, so that the impedance values on all control signal wires are uniform, and input and output signals of each stage of the GOA circuit are stable, and the image display quality is improved.

Description

technical field [0001] The invention relates to a GOA circuit of a liquid crystal display, in particular to a signal wiring structure for the GOA circuit. Background technique [0002] Currently, in an active matrix liquid crystal display (AMLCD, Active Matrix Liquid Crystal Display), each pixel has a thin film transistor (TFT, Thin Film Transistor), the gate of which is electrically connected to the horizontal scanning line, and the drain is electrically The source is electrically connected to the data line in the vertical direction, and the source is electrically connected to the pixel electrode. If enough positive voltage is applied to a scanning line in the horizontal direction, all the TFTs on the scanning line will be turned on. At this time, the pixel electrode corresponding to the scanning line will be connected to the data line in the vertical direction, and the data line will be The video signal voltage is written into the pixel, so as to control the light transmi...
