1. A driving circuit, comprising:
a light-emitting diode;
a driving transistor electrically connected to the light-emitting diode and configured to provide driving current to the light-emitting diode;
a first switch connected to a gate of the driving transistor, wherein the first switch is in a first state during a previous frame, and is in a second state during a current frame; and
a second switch, wherein the first switch is connected between the gate of the driving transistor and the second switch, and the second switch is in the second state during the previous frame, and is in the first state during the current frame;
wherein the first state is one of a conducting-and-cut-off switching state or a constant conducting state, and the second state is the other of the conducting-and-cut-off switching state or the constant conducting state.
