SHIFT REGISTER AND GATE DRIVING CIRCUIT USING THE SAME

摘要

The present invention relates to a gate driving circuit which includes N shift resisters which are connected sequentially to supply a scan signal to each gate line of a display device and allows output signals of the neighboring shift resisters to be partially overlapped. An n^th shift resistor (n is a natural number greater than 1 and less than or equal to N) comprises an input unit which outputs a directional input signal having an a gate high voltage (VGH) or a gate low voltage (VGL) by the output signal of an (n-2)^th shift resistor or an (n+2)^th shift resistor to a bootstrap node; a pull-up unit which is connected to the bootstrap node and activates a first clock signal by a signal of the bootstrap node to output the first clock signal to the gate line as an output signal; and a noise eliminating unit which outputs an output signal of an (n-1)^th shift resister to the bootstrap node by a fourth clock signal in the normal direction operation and outputs an output signal of an (n+1)^th shift resister to the bootstrap node by a second clock signal in the reverse direction operation.
