Abstract
A high-reliability gate driving circuit is disclosed for providing a plurality of gate signals to plural gate lines respectively. The gate driving circuit includes a plurality of shift register stages. Each shift register stage includes a pull-up unit, an energy-store unit, a buffer unit, a discharging unit, a first pull-down unit, a second pull-down unit and a control unit. The pull-up unit pulls up a gate signal according to a driving control voltage and a first clock. The buffer unit receives an input signal. The energy-store unit provides the driving control voltage through performing a charging process based on the input signal. The first pull-down unit pulls down the gate signal according to a control signal. The second pull-down unit pulls down the gate signal according to a second clock having a phase opposite to the first clock. The control unit generates the control signal based on the gate signal.
