Array substrate and repairing method

Abstract

The invention discloses an array substrate and repairing method. The array substrate comprises a first public electric potential signal wire, a second public electric potential signal wire, a plurality of data wires and a plurality of first public electrode wires, each data wire corresponds to one first public electrode wire, the first public electrode wires are respectively communicated with the first public electric potential signal wire and the second public electric potential signal wire, each first public electrode wire is provided with a second public electrode wire communicated with the first public electrode wire, the second public electrode wires are respectively communicated with a first repairing cross wire and a second repairing cross wire, and the first repairing cross wire and the second repairing cross wire are both crossed with the data wires. The invention can keep a repaired peripheral public electrode pattern complete without lowering the supply capacity of public electrode current, reduces various bad displays caused by the reduction of the supply capacity, can reduce the time of laser welding and laser cutting during the reparation, improves the repairing rhythm in production, and saves the labor hour.

Description

technical field [0001] The invention relates to an array substrate, in particular to an array substrate and a repair method for repairing broken data lines. Background technique [0002] Thin film transistor liquid crystal display (TFT-LCD) has become the most widely used flat-panel display device in the world. It is formed by array substrate, color filter substrate and liquid crystal filled between the two substrates. Determine the orientation of liquid crystal molecules to adjust the polarization direction of light to achieve the purpose of displaying images. [0003] The current array substrate structure mainly includes pixels, scanning lines, data lines, common electrode lines, wiring protection units, crimping electrodes, etc. figure 1 Shown is a brief circuit diagram of an array substrate of a thin film transistor liquid crystal display in the prior art. [0004] Such as figure 1 As shown, the scan lines G1 , G2 . . . Gn and the common electrode lines COM are arrang...
