Title:
SHIFT REGISTER, GATE DRIVE CIRCUIT, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/124721
Kind Code:
A1
Abstract:
A shift register, gate drive circuit, and display device. The shift register comprises: an input module (1), a first reset module (2), a first control module (3), a second control module (4), a node voltage control module (5), and an output module (6). By coordinating the six modules, and configuring the node voltage control module (5) to form a bootstrap circuit with the second control module (4), the voltage of a second node (B) is the same as the voltage of an effective pulse signal of a first clock signal end (CK1), such that the first control module (3) can timely and effectively operate under the control of the second node (B). In this way, a drive signal output end of the shift register can timely output a signal having a potential in reverse to an effective pulse signal at an input signal end upon completion of an output operation, thus improving output stability of the shift register, reducing noise of a scan signal outputted at the drive signal output end, and accordingly improving stability of the scan signal.
