Abstract
Embodiments may be directed to a gate driving circuit. The gate driving circuit includes a pre-charge unit, a pull-up unit, a boosting unit, and a discharge unit. The pre-charge unit pre-charges a first node in response to a first input signal. The pull-up unit outputs a first clock signal as a gate driving signal in response to a first node signal of the first node. The boosting unit boosts the first node signal of the first node in response to the first node signal and the first clock signal. The discharge unit discharges the first node to a gate-off voltage level in response to a second input signal and a second clock signal.
Claims19
A gate driving circuit, comprising:
- a pre-charge unit pre-charging a first node in response to a first input signal;
- a pull-up unit outputting a first clock signal as a gate driving signal in response to a first node signal of the first node;
- a boosting unit boosting the first node signal of the first node in response to the first node signal and the first clock signal, wherein the boosting unit includes a first capacitor connected between the first node and a second node and wherein the first node is directly connected to the first capacitor and the second node is directly connected to the first capacitor;
- and
- a discharge unit discharging the first node through the second node to a gate-off voltage level in response to a second input signal and a second clock signal.
A display device, comprising:
- a plurality of stages which are dependently connected,
- wherein each of the stages includes:
- a pre-charge unit pre-charging a first node in response to a first input signal;
- a pull-up unit outputting a first clock signal as a gate driving signal in response to a first node signal of the first node;
- a boosting unit boosting the first node signal of the first node in response to the first node signal and the first clock signal, wherein the boosting unit includes a first capacitor connected between the first node and a second node and wherein the first node is directly connected to the first capacitor and the second node is directly connected to the first capacitor;
- and
- a discharge unit discharging the first node through the second node to a gate-off voltage level in response to a second input signal and a second clock signal.
