Patent ID: 8884681

Claim:
A gate driving device, comprising: a gate driving unit, comprising a bi-directional shift register circuit for generating a plurality of gate driving signals according to a start pulse to drive a plurality of pixels in a pixel array, wherein the bi-directional shift register circuit comprises 1˜N stages of shift registers coupled in serial, and N is a positive integer, a first stage shift register generates a first output signal and an N-th stage shift register generates a second output signal; a first control unit, coupled to the gate driving unit and comprising an input terminal receiving the first output signal of the gate driving unit and a first clock input terminal receiving a first clock signal; a second control unit, coupled to the gate driving unit and comprising an input terminal receiving the second output signal of the gate driving unit and a first clock input terminal receiving a second clock signal; and a switch unit, coupled to the first control unit and the second control unit at a carryout signal output node, wherein the first control unit and the second control unit generates a carryout signal at the carryout signal output node according to the first output signal and the second output signal.
