Abstract:
A gate driving circuit includes a plurality of shift registers coupled in series. An nth shift register includes a driving circuit and a pull-down circuit. The driving circuit is electrically coupled to an output node and a first node. The driving circuit is configured to receive a first clock signal and output a gate signal according to the first clock signal. The pull-down circuit is electrically coupled to the output node. The pull-down circuit is configured to receive an (n−m)th gate signal and an (n+m)th gate signal, and pull-down the gate signal to a low voltage level according to one of the (n−m)th gate signal and the (n+m)th gate signal, wherein m and n are positive integers.
