Problems solved by technology

[0005] As the GOA technology is applied to the small board (slim boarder) LCD, in order to reduce the space occupied by the display panel, the distance between the GOA bus (Bus line) and the glass cutting edge is getting shorter and shorter. The defect rate caused by damage to the GOA bus also increases

Abstract

The invention provides a repairing circuit for a displaying panel, comprising a substrate, two groups of bus-bars, and at least one repairing wire, wherein the two groups of bus-bars are arranged on the substrate; each group of bus-bar comprises a plurality of identical leads; the at least one repairing wire is arranged above or below the bus-bar in an insulating manner and is crossed to each lead. The repairing circuit can introduce the signal of the lead at the other side when the lead of one bus-bar of the displaying panel driven at two sides is cracked, thus repairing the dual-sided driving function and avoiding the insufficiently charging problem resulting from single-sided driving; furthermore, the reject rate of the panel due to fracture of the lead can be reduced; and the space occupied by the repairing wire is not enlarged, and the identical panel design is maintained.

Description

technical field [0001] The present invention relates to a display panel repair circuit, in particular to a display panel repair circuit using array substrate row driving technology. Background technique [0002] In an active matrix liquid crystal display (Active Matrix Liquid Crystal Display), each pixel has a TFT, its gate (Gate) is connected to the horizontal direction scanning line, the drain (Drain) is connected to the vertical direction data line, and the source Level (Source) is connected to the pixel electrode. [0003] If enough positive voltage is applied to a scanning line in the horizontal direction, all the TFTs on the line will be turned on. At this time, the pixel electrodes on the line will be connected to the data lines in the vertical direction, and the data lines on the data lines will be connected to each other. The video signal voltage is written into the pixel to control the transmittance of different liquid crystals to achieve the effect of color contr...
