Title:
SHIFT REGISTER AND DRIVING METHOD THEREFOR, GATE DRIVER CIRCUIT, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/062245
Kind Code:
A1
Abstract:
Disclosed are a shift register and driving method therefor, a gate driver circuit, and a display device. The shift register comprises an input circuit, a reset circuit, a first control circuit, a first output circuit, and a second output circuit. The first output circuit has two output paths, one of the paths being a drive signal output end for providing a signal of a first clock signal end to the shift register under the joint control of the first clock signal end and a signal of a first node, and the other path being a drive signal output end for providing a signal of a second clock signal end under the joint control of the second clock signal end and the signal of the first node. In addition, by cooperating with the other four circuits, the first output circuit can make the two paths operate alternately, such that current can be avoided from only flowing through one path, and the service life of the shift register can be improved.
