Shift register unit, driving method, gate driving circuit and display device

Abstract

The present invention provides a shift register unit, a driving method, a gate driving circuit and a display device. The shift register unit includes an input unit, a first control unit, a first CMOS phase inverter, a second control unit, a carry signal output unit which is used for controlling the potential of carry signals outputted from a carry signal output end and the phase inversion of the potential of a second control node, and a gate driving signal output unit which is used for controlling a gate driving signal output end to output a second electric level when the potential of the carry signals is at the second electric level, and controlling the gate driving signal output end to output second clock signals when the potential of the carry signals is at a first electric level. According to the shift register unit of the invention, a simple CMOS transmission gate, the CMOS phase inverter and a single tube are adopted, so that gate driving signal output can be realized. With the shift register unit adopted, the number of transistors is smaller, power consumption is lower, false output can be avoided, the performance and stability of a panel can be better improved, and yield can be improved.

Description

technical field [0001] The invention relates to the technical field of display driving, in particular to a shift register unit, a driving method, a gate driving circuit and a display device. Background technique [0002] At present, with the fierce competition in the LCD panel industry, reducing panel costs and improving performance have become the competition points of panel manufacturers. Among them, the adoption of GOA (Gate On Array, array substrate row drive circuit) can reduce IC usage, so it has become the key to reducing costs. A direct approach, the attempt and adoption of a new structure effectively improves performance and power consumption. In the CMOS (Complementary Metal Oxide Semiconductor, Complementary Metal Oxide Semiconductor) GOA of the display panel, the reduction of the number of transistors used, the reduction of power consumption and the reduction of false output are always a key consideration for the improvement of the performance of the GOA circuit....
