Claim 0:
1. A driving circuit, comprising:
an input circuit configured to output a control signal upon receiving a trigger signal;
a first output circuit comprising a control terminal connected to an output terminal of the input circuit, and configured to output a first output signal upon receiving the control signal and a first input signal;
a second output circuit comprising a control terminal connected to the output terminal of the input circuit and configured to output a second output signal upon receiving the control signal and a second input signal; and
a pull-down circuit comprising:
an input terminal connected to the output terminal of the input circuit, an output terminal of the first output circuit and an output terminal of the second output circuit; and
an output terminal connected to a first low level voltage and configured to pull down the control signal, the first output signal and the second output signal to a low level when a pull-down control signal is at a high level, and stop pulling down the control signal, the first output signal and the second output signal when the trigger signal or the control signal is at the high level,

wherein the pull-down circuit comprises:
a pull-down holding circuit comprising an input terminal connected to the output terminal of the input circuit, and the pull-down holding circuit being configured to output a pull-down signal according to the pull-down control signal, and pull down the pull-down signal according to the trigger signal and the control signal; and
a pull-down sub-circuit comprising:
a control terminal connected to the output terminal of the pull-down holding circuit;
an input terminal connected to the output terminal of the input circuit, the output terminal of the first output circuit and the output terminal of the second output circuit; and
an output terminal connected to the first low level voltage, and configured to pull down the control signal, the first output signal and the second output signal to the low level upon receiving the pull-down signal.
