摘要: A gate driving circuit for driving plural scan lines of a liquid crystal display includes N driving circuit units and a control unit. Each of the N driving circuit units sequentially outputs a driving signal to drive a corresponding scan line of the scan lines. The control unit outputs a positive-phase and an opposite-phase clock signal to control the N driving circuit units. After an Nth driving circuit unit of the N driving circuit units outputs the driving signal, the control unit transmits a control signal to at least one of the N driving circuit units. A method for driving the foregoing gate driving circuit is also disclosed.
