Gate driving circuit and display apparatus having the same
Abstract:
A gate driving circuit and a display apparatus having the gate driving circuit include a pull-up part and a carry part pull up a present gate signal and a present carry signal, respectively, to a first clock during a first period within one frame. A pull-down part receives a next gate signal to discharge the present gate signal to a source power voltage. A pull-up driving part is connected to control terminals of the carry part and pull-up part (Q-node) to turn the carry part and pull-up part on and off. A floating preventing part prevents an output terminal of the carry part from being floated in response to the first clock during a second period within the one frame.
