Wiring structure for GOA (Gate driver On Array) circuit

Abstract

The invention provides a wiring structure for a GOA (Gate driver On Array) circuit. The wiring structure comprises a scan line to be measured and a rescue line, wherein the scan line to be measured is located in the GOA circuit, and the rescue line is located in the GOA circuit. The scan line to be measured and the rescue line are at least partially overlapped and are electrically coupled in a welding manner, so as to achieve the function of multiplexing the rescue line. Compared with the prior art, the wiring structure has the advantages that the scan line to be measured is electrically coupled to the rescue line in the welding manner, so that the sharing between dummy gate wires in a liquid crystal cell and the rescue line is realized, then, the number of the dummy gate wires in the GOA circuit is reduced, and high-frequency signal interference caused by line variety is lowered. In addition, a simple circuit design is utilized, and the function of multiplexing the rescue line is achieved through testing switching cooperation between a first resistor and a second resistor which are additionally arranged on a circuit board, so that the number of wires in the GOA circuit is reduced, the location of the scan line to be measured can be freely changed and selected, and then, the flexibility of measurement is improved.

Description

technical field [0001] The invention relates to a gate drive circuit of a liquid crystal display device, in particular to a wiring structure of a row drive circuit of an array substrate. Background technique [0002] Array substrate row drive (Gate Driver on Array, GOA) technology is a kind of gate driver ICs made directly on the array substrate (Array Substrate) instead of the gate driver chip made of external silicon wafers. technology. Generally speaking, a liquid crystal panel using GOA technology in a thin film transistor liquid crystal display (Thin Film Transistor Liquid Crystal Display, TFT-LCD) is called a GOA liquid crystal. Compared with traditional TFT-LCDs, GOA liquid crystals can not only save costs, but also help increase production capacity because the bonding process in the direction of the gate is omitted. [0003] During the manufacturing process of the GOA circuit, due to the short circuit or open circuit of the GOA gate, the short circuit or open circu...
