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.

Abstract: The present disclosure provides a phased-array antenna and a control method thereof. The phased-array antenna includes two parallel substrates attached by sealant into a cavity filled with liquid crystals, a plurality of phase-shifting units is provided in the cavity defined. Each unit comprises: a power feeder electrically connected to a radio frequency signal terminal, a radiator electrically connected to the power feeder, a ground electrode electrically connected to a ground signal terminal but electrically insulated from the power feeder and the radiator respectively, and a driving electrode electrically connected to a control signal wire. The orthographic projections of the driving electrode, the power feeder, and the ground electrode overlap on one substrate.
