    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.
