Abstract

An embodiment of the invention discloses a circuit repair structure and method, and aims to repair an open circuit formed at the intercrossing position of electric wires extending along different directions on a thin film transistor array substrate. The circuit repair structure comprises a repair wire and a protection pattern. The repair wire extends towards the same side of the electric wires at which the open circuit point located and connects two ends of the open circuit point. The repair wire penetrates another electric wire crossed the electric wire at which the open circuit located. The protection pattern is arranged between the repair wire and the electric wire that the repair wire crosses.

Description

technical field [0001] The invention relates to the field of display panels, in particular to a circuit repair structure and a circuit repair method of a display panel. Background technique [0002] Existing display panels are generally driven by active thin film transistor arrays. Each pixel needs to be connected to criss-cross scan lines and data lines for selection and display voltage input. Since the existing display panel has several million pixels, the required scanning lines and data lines are also close to 10,000. However, as long as a few of so many circuits are disconnected, the entire display panel will be reduced to a defective product, which greatly affects the yield rate of the display panel and increases the finished product of the display panel. [0003] Therefore, it is necessary to provide a line repair method and a line repair structure capable of solving the above problems. Contents of the invention [0004] In order to solve the above-mentioned tech...
