Abstract

The invention provides a flat display panel and a method for repairing a circuit. The flat display panel comprises a plurality of bridging lines arranged between adjacent common electrode wires; when the problem of short circuit occurs, the common electrode wire with short circuit can be directly cut off; a conducting path of common voltage is changed by the bridging lines to complete circuit repairing; and the method can effectively improve the operating performance and the qualification rate of the flat display panel.

Description

Technical field [0001] The present invention provides a flat display panel and a circuit repair method thereof, and more particularly relates to a flat display panel and a circuit repair method that can be repaired without going through a rescue line. Background technique [0002] Compared with traditional non-flat displays, such as cathode ray tube displays, flat displays have the characteristics of light weight and thin thickness, and have gradually become mainstream products in the display market. They are widely used in home TVs, personal computer displays, and mobile phones, digital Portable electronic products such as cameras and portable music players. [0003] As the development of flat-panel displays continues to trend toward high-resolution designs, the distribution of wires such as scan lines and data lines on the flat display panel is becoming more and more dense, so the process difficulty is relatively increased, causing adjacent wires to be prone to short circuits. ...
