摘要:
A gate driving circuit is provided which includes a plurality of stages cascade-connected with each other and outputting a plurality of gate signals. An n-th (n is a natural number) stage includes a gate output part, a first node control part and a carry part. The gate output part includes a first transistor. The first transistor outputs a high voltage of a clock signal to a high voltage of an n-th gate signal in response to a high voltage of a control node. The first node control part is connected to the control node to control a signal of the control node and includes at least one transistor having a channel longer than the channel length of the first transistor. The carry part outputs the high voltage of the clock signal to an n-th carry signal in response to the signal of the control node.

A display apparatus includes a gate driver which sequentially outputs a gate signal at a high state in response to a gate control signal and a data driver which converts image data into a data signal in response to a data control signal. The display apparatus further includes a display panel which includes a plurality of gate lines which sequentially receive the gate signal, a plurality of data lines which receive the data signal and a plurality of pixels connected to the gate and data lines and which receive the data signal in response to the gate signal to display an image. The polarity of the data signal is inverted after the gate signal transitions to a low state.

A pull-up driving part maintains a signal of a first node at a high level by receiving a turn-on voltage in response to one of a previous stage or a vertical start signal. A pull-up part outputs a clock signal through an output terminal in response to the signal of the first node. A first holding part maintains a signal of a second node at a high level or a low level when the signal of the first node is respectively low or high. A second holding part maintains the signal of the first node and a signal of the output terminal at a ground voltage in response to the signal of the second node or a delayed and inverted clock signal.

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.
