Abstract
A gate driving unit includes a shift register including a forward input sub-circuit and a backward input sub-circuit, and a forward-backward scanning controller. The forward-backward scanning controller transmits a first clock signal provided by the first clock signal terminal to the forward input sub-circuit and the backward input sub-circuit for forward scanning, and transmits a second clock signal provided by the second clock signal terminal to the forward input sub-circuit and the backward input sub-circuit for backward scanning. The forward input sub-circuit transmits a signal provided by the forward-backward scanning controller to the pull-up node under control of an enabling signal provided by the forward scanning input terminal, and the backward input sub-circuit transmits the signal provided by the forward-backward scanning controller to the pull-up node under control of an enabling signal provided by the backward scanning input terminal.
