    摘要: A shift register and a driving method therefor, a gate driving circuit and a display apparatus. The shift register comprises a trigger 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 terminal of the shift register and a signal output from a transmission signal output terminal. The pull-down module is used for pulling down a signal output from the output terminal of the shift register and the signal output from the transmission signal output terminal. The denoising module is used for cutting off the connection path between the transmission signal output terminal and a second terminal 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 transmission signal output from the transmission signal output terminal generate a sparkle noise or the like, when a voltage jump occurs at a pull-up node thereof, so that a shift transmission signal of the shift register is more stable, thereby making the signal output from the shift register more stable.

    摘要: There are provided in the present disclosure a shift register and a driving method thereof, a gate driving circuit and a display apparatus. The shift register of the present disclosure includes: a forward scanning input sub-circuit for pre-charging a potential of a pull-up node by an operation level signal under control of a forward input signal and a forward scanning signal upon scanning forwards; a backward scanning input sub-circuit for pre-charging the potential of the pull-up node by an operation level signal under control of a backward input signal and a backward scanning signal upon scanning backwards; an output sub-circuit for outputting a clock signal through a signal output terminal under control of the potential of the pull-up node; wherein the pull-up node is a connection node of the forward scanning input sub-circuit, the backward scanning input sub-circuit and the output sub-circuit.
