Problems solved by technology

However, as the resolution of the panel increases, the distance between two adjacent scan pads 160 or the distance between two adjacent data pads 170 will inevitably become narrower.
Therefore, it is still difficult to repair the damaged circuit by laser cutting, which will reduce the production yield of the thin film transistor array substrate 100 and increase the production cost.

Abstract

The invention relates to an array substrate of a thin film transistor, comprising a substrate, a plurality of electrode wirings, a plurality of pixel units, a plurality of pads and a plurality of switch assemblies. The substrate has a display region and a peripheral line region. The electrode wirings are configured on the substrate and divide the display region into a plurality of pixel regions. Each pixel unit is respectively configured in one of the pixel regions and driven by the electrode wirings. The pads are configured in the peripheral line region. Each pad comprises a first main body part and a first extending part. The first extending part is narrower than the first main body part. Each pad is electrically connected with corresponding electrode wiring. The switching assemblies are configured in the peripheral line region, and at least one switch assembly is configured between two adjacent pads. Each switch assembly is electrically connected with the pads on both sides of the switch assembly.

Description

technical field [0001] The present invention relates to an array substrate and a display panel, and in particular to a thin film transistor array substrate (Thin Film Transistor array substrate, TFTarray substrate) which is easy to repair (Electrostatic dischargerepair) the circuit damaged by static electricity and has The liquid crystal display panel (LCD panel) of the thin film transistor array substrate. Background technique [0002] In recent years, due to the maturity of optoelectronic technology and semiconductor manufacturing technology, the flat panel display (Flat Panel Display) has been vigorously developed. Among them, thin film transistor liquid crystal display (ThinFilm Transistor Liquid Crystal Display, TFT-LCD) is based on its low voltage operation, operation speed Due to the advantages of high speed, light weight and small size, it has gradually become the mainstream of display products. [0003] The thin film transistor liquid crystal display mainly include...
