Abstract

The invention discloses a gate drive circuit, a display device and a repair method. The gate drive circuit comprises a plurality of cascaded GOA units, a plurality of clock signal lines, a plurality of clock signal lines for repair and a plurality of electrostatic protection sub-circuits, wherein each clock signal line is used for providing various clock signals for the GOA unit; the clock signalline for repairing is used for replacing the broken clock signal line to transmit a corresponding clock signal when any clock signal line is broken; each electrostatic protection sub-circuit is connected with the corresponding clock signal line and the corresponding clock signal line for repair through connecting lines, and is used for preventing the clock signal line and each clock signal line for repair from electrostatic damage; the connecting lines, the clock signal lines and the clock signal lines for repairing are arranged on different layers of the circuit board, and the orthographic projections of the connecting lines on the planes where the corresponding clock signal lines or the corresponding clock signal lines for repairing are located intersect with the corresponding clock signal lines and the corresponding clock signal lines for repairing respectively.

Description

technical field [0001] The present disclosure generally relates to the field of circuit repair, and in particular relates to a gate drive circuit, a display device and a repair method. Background technique [0002] Most of the existing flat panel display devices use a Gate Driver On Array (GOA for short) technology consisting of multiple cascaded shift registers. Technology, the use of GOA technology can reduce the use of IC (Integrated Circuit), thereby reducing the manufacturing cost of display devices. [0003] With the improvement of the resolution of the display device, the density of the gate drive circuit in the display device is getting higher and higher, and the width of the clock signal line used for the gate drive circuit is getting narrower, so that the clock signal line is prone to disconnection . Contents of the invention [0004] The main purpose of the inventors of the present invention is to provide a gate driving circuit, a display device and a repairin...
