Abstract

The invention discloses a shifting register, a gate driving circuit, a display panel and a display device. The shifting register comprises an input module, a reset module, a pull-up module, a pull-down module and an output control module, and further comprises an input protection module. According to the shifting register, the input module, the reset module, the pull-up module, the pull-down module and the output control module can be controlled by respective control terminals to output scanning signals and achieve the gate driving effect; as the input protection module is additionally arranged, a signal input end is connected with a second reference signal end when the signal input end generates static electricity, the static electricity is directly discharged through the second reference signal end, it is prevented that the shifting register is damaged when the static electricity is led in, and the static-electricity protection capacity of the shifting register is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a shift register, a gate drive circuit, a display panel and a display device. Background technique [0002] At present, with the development of liquid crystal display technology, the competition in the liquid crystal panel industry is becoming more and more fierce. Reducing the production cost of liquid crystal display panels has become the first choice for panel manufacturers to improve their competitiveness. In order to reduce the production cost of display panels, generally, related technologies Technical personnel in the field use the edge of the display panel to build a gate drive circuit. The gate drive circuit includes multiple shift registers, each of which corresponds to a gate line. Multiple shift registers are arranged in series, and two adjacent shift registers There are trigger signals transmitted step by step between the bit registers. After each shift register rec...
