摘要： A method of driving a gate line includes: charging one of a scan start signal and a carry signal provided from a previous stage to a first node of a present stage; outputting a gate signal through a gate node of the present stage by pulling up a high level of a first clock signal at the first node to boost up a voltage potential of the first node; discharging the voltage potential of the first node and a voltage potential of the gate node to hold the first node and the gate node at a first power voltage as the first clock signal is shifted to a low level; and receiving a voltage potential signal of a second node of the previous stage, the second node holding a gate signal outputted from the previous stage, to reduce a ripple generated at the first node.

摘要： In a gate driving circuit and a display apparatus having the gate driving circuit, a pull-up transistor of a present stage among plural stages, which are connected one after another to each other and sequentially output a gate signal, pulls up a present gate signal output through an output terminal to a gate-on voltage. A buffer transistor is connected to a control terminal of the pull-up transistor to receive a previous output signal from a previous stage and to turn on the pull-up transistor. The buffer transistor has a chargeability that is about two times or greater than the chargeability of the pull-up transistor. Thus, the size of the pull-up transistor may be reduced, thereby preventing a malfunction of the gate driving circuit when the gate driving circuit is operated under conditions of high temperature or low temperature.
