Provided are a sensing circuit and a sensing method thereof, a sensor chip, and a display panel. The sensing circuit includes a first transistor including a first gate and a second gate, a first capacitor, a read circuit, and a bias compensation circuit. The first gate receives a sensing signal outputted by a sensor. The first capacitor is connected between the second gate and a first fixed potential signal terminal. The read circuit is connected between the first transistor and an output terminal of the sensing circuit. The bias compensation circuit is electrically connected to the first transistor and configured to input a bias voltage into the second gate of the first transistor. The bias voltage received by the second gate reduce the threshold voltage drift of the first transistor.

Sensing circuit and sensing method thereof, sensor chip, and display panel

An antenna and its fabrication method, and a display device are provided. The antenna includes a substrate, a radiation electrode, a first dummy electrode, and a feed line. The radiation electrode, the first dummy electrode, and the feed line are disposed on the substrate. The feed line is coupled and connected to the radiation electrode. The first dummy electrode and the radiation electrode are adjacent but not connected to each other. Along a first direction, an orthographic projection of the radiation electrode to a plane where the substrate is located is a first projection, and an orthographic projection of the first dummy electrode to the plane where the substrate is located is a second projection. There is a first interval between the first projection and the second projection; and the first direction is perpendicular to the plane where the substrate is located.

Antenna and its fabrication method, and display device

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.
