Abstract:
The fingerprint sensing circuit includes sensing units and a sensing circuit. The sensing units are arranged as columns and rows. Each of the sensing units includes a sensing electrode. The sensing circuit is electrically connected to the sensing electrodes in at least two first sensing units of the sensing units in a first period to obtain a first fingerprint grey level.
