Abstract

The invention provides an array substrate and a liquid crystal display panel. The array substrate comprises LCQ (liquid crystal display quick) test wire harnesses, driving wire harnesses, ADD wire harnesses, first thin film transistors, second thin film transistors and third thin film transistors. The first thin film transistors, the second thin film transistors and the third thin film transistors comprise gate electrodes, gate insulation layers, semiconductor layers, first electrodes and second electrodes, the three first electrodes of each first thin film transistor, the corresponding second thin film transistor and the corresponding third thin film transistor comprise first metal layers, the three second electrodes of each first thin film transistor, the corresponding second thin film transistor and the corresponding third thin film transistor comprise second metal layers, the first metal layers and the second metal layers are arranged at intervals, the first metal layers are electrically connected with the LCQ test wire harnesses, the second metal layers are electrically connected with the driving wire harnesses, the gate electrodes of the first thin film transistors are electrically connected with the first metal layers, and the gate electrodes of the second thin film transistors are electrically connected with the second metal layers. The array substrate and the liquid crystal display panel have the advantage that control on ESD (electro-static discharge) and LCQ can be reduced on the premise that functional characteristics of the liquid crystal display panel are guaranteed.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to an array substrate and a liquid crystal display panel. Background technique [0002] The preparation of the liquid crystal display panel includes the array substrate (Array) process, the color filter substrate (CF) process, and the cell alignment (Cell) process of the array substrate and the color filter substrate. Generally, the panel function test (CellTest) is performed during the Cell process. To detect defects in the display panel in the three processes of Array, CF, and Cell, and identify defective products layer by layer. At present, the commonly used method of Cell Test is to deflect liquid crystal molecules for image quality detection through the anti-terminal side of dataline and gateline and part of LCQ (Liquid Crystal Display Quick) injection signal. LCQ principle: open TFT (Thin Film Transistor, thin film transistor) through ADD signal ), and then the...
