Claim:
1. A gate driving circuit comprising: a control unit controlling the driving circuit to work orderly and recurrently in a first cut-off state, a first driving state, a second driving state and a second cut-off state; wherein the gate driving circuit further comprises: a driving unit for driving the gate driving circuit; a first negative voltage input for defining the voltages output from the driving unit; a driving voltage input providing voltages to the driving unit; and a control signal input for switching on the driving unit; wherein, when the driving unit works in the first cut-off state, the control unit controls the first negative voltage input to connect to the driving unit; when the driving unit works in the first driving state, the control unit controls the driving voltage input and the control signal input to connect to the driving unit respectively; and the control unit controls the first negative voltage input to disconnect to the driving unit; when the driving unit works in the second driving state, the control unit controls the driving voltage input to connect to the driving unit; and the control unit controls the control signal input disconnect to the driving unit; when the driving unit works in the second cut-off state, the control unit controls the first negative voltage input to connected to the driving unit; and the control unit controls the driving voltage input to disconnect to the driving unit.
