Abstract: A driving circuit, a method for driving the same, and a microfluidic device are provided. The driving circuit includes a constant voltage writing module configured to transmit a constant voltage to an output terminal of the driving circuit, an AC voltage writing module configured to transmit an AC voltage to the output terminal of the driving circuit, a first switch, and a first capacitor. The first switch includes an input terminal electrically connected to a third signal line, an output terminal electrically connected to control terminals of the AC voltage writing module and the constant voltage writing module, and a control terminal electrically connected to a first scan line. The first capacitor is configured to stabilize a potential of the output terminal the first switch.
