Title:

SHIFT REGISTER AND DRIVING METHOD THEREFOR, GATE DRIVE CIRCUIT AND DISPLAY APPARATUS

Document Type and Number:

WIPO Patent Application WO/2016/179982

Kind Code:

A1

Abstract:

A shift register and a driving method therefor, a gate drive circuit and a display apparatus. The shift register comprises a triggered reset module, a pull-up module, a first capacitor and a pull-down module, and further comprises a denoising module. The pull-up module is used for pulling up a signal output from an output end of the shift register and a signal output from a delivery signal output end. The pull-down module is used for pulling down a signal output from the output end of the shift register and a signal output from the delivery signal output end. The denoising module is used for cutting off the connection passage between the delivery signal output end and a second end of the first capacitor in a pull-down phase. The shift register, by providing the denoising module, makes it possible to prevent a coupling effect of the capacitor from making a delivery signal output from the delivery signal output end generate a sparkle noise or the like, when a voltage jump occurs at a pull-up node thereof, so that a shift delivery signal of the shift register is more stable, thereby making the signal output from the shift register more stable.
