Abstract:
A driving circuit and a display panel are disclosed. The driving circuit includes a plurality of cascaded driving units. The driving unit includes a forward/backward scan control module, a first control node controlling module, a second control node controlling module, a global control module, a regulating module, a first output module configured to output a stage signal, and a second output module configured to output a gate driving signal. A voltage level of the gate driving signal is higher than a voltage level of the stage signal.
