Title:

SHIFT REGISTER UNIT, GATE DRIVE CIRCUIT, DISPLAY DEVICE AND DRIVE METHOD

Document Type and Number:

WIPO Patent Application WO/2019/134450

Kind Code:

A1

Abstract:

A shift register unit, a gate drive circuit, a display device and a drive method. The shift register unit comprises an input circuit (110), a first node reset circuit (120), an output circuit (130) and a noise reduction touch circuit (140). The input circuit (110) is configured to control the level of a first node (PU) in response to an input signal; the first node reset circuit (120) is configured to reset the first node (PU) in response to a reset signal; the output circuit (130) is configured to output a drive signal to an output end (OUT) under the control of the level of the first node (PU); and the noise reduction touch circuit (140) is configured to reset the first node (PU) in response to a turn-on touch signal. The shift register unit can effectively control the potential of the first node in a touch scanning phase, improving the display quality of a display device comprising the shift register unit.
