Abstract
A gate driving circuit having a low leakage current control mechanism is disclosed for providing a plurality of gate signals forwarded to a plurality of gate lines respectively. The gate driving circuit includes a plurality of shift registers. Each shift register includes a driving unit, an energy store unit, a buffer unit, a voltage regulation unit, and a control unit. The driving unit generates a gate signal based on a driving control voltage and a first clock. The buffer unit functions to receive a start pulse signal. The energy store unit provides the driving control voltage through performing a charging process based on the start pulse signal. The control unit generates a control signal based on the first clock and a second clock having a phase opposite to the first clock. The voltage regulation unit regulates the driving control voltage based on the control signal.
