Abstract
A gate driver includes an input circuit, a pull-up circuit, a pull-down circuit, a QB node control circuit and a Q node control circuit. The input circuit transmits an input signal to a Q node in response to a first clock signal. The pull-up circuit pulls up a gate output signal to a high voltage in response to a signal of a QF node. The pull-down circuit pulls down the gate output signal to a low voltage in response to a QB node. The QB node control circuit controls a signal of the QB node based on a QB control signal and a second clock signal. The Q node control circuit controls a signal of the Q node based on the QB node.
