1. A driving circuit, comprising a plurality of cascaded driving units, the driving unit comprising:
a forward/backward scan control module, configured to control the driving circuit to perform a forward scan according to a forward scan control signal or control the driving circuit to perform a backward scan according to a backward scan control signal;
a first control node controlling module, electrically connected to the forward/backward scan control module, wherein an output end of the first control node controlling module is electrically connected to a first control node to control a voltage level of the first control node;
a second control node controlling module, electrically connected to the forward/backward scan control module and the first control node controlling module, wherein an output end of the second control node controlling module is electrically connected to a second control node to control a voltage level of the second control node;
a global control module, configured to control the driving unit to output a global control signal;
a regulating module, configured to maintain the voltage level of the second control node;
a first output module, electrically connected to the first control node and the second control node, configured to output a stage signal; and
a second output module, electrically connected to the first control node and the second control node, configured to output a gate driving signal;
wherein a voltage level of the gate driving signal is higher than a voltage level of the stage signal.
