摘要: 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.

摘要: A liquid crystal display device and driving method thereof that are capable of generating positive and negative bias voltages the absolute values of which are symmetrical. The liquid crystal display device of the present invention includes a pulse generator for generating a pulse signal, a positive bias voltage generator for generating a positive bias voltage using (by rectifying) the pulse signal and a negative bias voltage generator for generating a negative bias voltage the absolute value of which is substantially symmetrical with the absolute value of the positive bias voltage. The pulse generator generates the pulse signal based on feedback of at least one of the positive and negative bias voltages.
