Abstract: A microfluidic apparatus, and its drive circuit and drive method are provided in the present disclosure. The drive circuit includes at least one switch unit, where the switch unit includes a first signal input terminal, a signal output terminal, first and second control signal terminals, a signal terminal, a first module, a second module, and a third module. The first module is electrically connected to the first signal input terminal, the signal output terminal and the second module; and the second module is electrically connected to the first control signal terminal. The first control signal terminal is configured to control the first module and the second module to be in conduction or disconnection, and the second control signal terminal is configured to control the third module to in conduction or disconnection, thereby controlling the signal output terminal to output a first or second signal.
