Abstract

A shift register, a gate electrode drive circuit, a display panel, and a display apparatus, the shift register comprising: an input module (01), used for outputting a signal of a signal input terminal (Input) to a first node (P1); a reset module (02), used for outputting a signal of a signal reset terminal (Reset) to the first node (P1); an output module (03), used for outputting a signal of the first node (P1) to a scanning signal output terminal (Out); a buffering module (04), used for outputting a signal of the first node (P1) to a trigger signal terminal (STV); an auxiliary module (05), used for outputting to a second node (P2) a high voltage signal inputted by a clock signal terminal (CLK), the second node (P2) controlling a control output module (03) to output a scanning signal to a scanning signal output terminal (Out). By means of the addition of the auxiliary module (05), the shift register, when outputting a scanning signal, selects an input clock signal, and can thereby reduce the power consumption of the shift register, thus improving the yield of the display panel.

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...
