Abstract:
A gate driver, including multiple stages of gate driving circuits, wherein each stage of the gate driving circuits includes an input part configured to generate a Q node signal in response to a carry signal of one of previous stages and a clock signal, the Q node signal being applied to Q node, an output part configured to output a gate output signal to a gate output terminal in response to the Q node signal, and a charge sharing part connected to the gate output terminal of a present stage and a gate output terminal of one of next stages, the charge sharing part configured to operate charge-sharing between the gate output signal of the present stage and a gate output signal of one of the next stages in response to a select signal.
