Abstract

A driving circuit, a driving method and a microfluidic substrate are provided. The driving circuit includes a first switching unit, a second switching unit, a reset unit, a first capacitor, and a second capacitor. In a first stage of a driving process of the driving circuit, the first switching unit is turned on, a first voltage signal is transmitted to a first node, the second switching unit is turned on, a second voltage signal is input to an output terminal of the driving circuit, and the driving circuit outputs an AC signal. In a second stage of the driving process, the first switching unit is turned off, the valid signal output by the second scan signal terminal controls the reset unit to be turned on, a third voltage signal is input to the output terminal of the driving circuit for reset, and the driving circuit outputs a DC signal.
