Abstract
A fingerprint identification system is provided. The fingerprint identification system includes a sensing panel and a driving circuit. The sensing panel includes a plurality of sensors. Each of the sensors transmits a sensing signal and a reference signal through two signal transmission paths. The driving circuit is coupled to the sensing panel. The driving circuit is configured to drive the sensing panel, and execute a fingerprint identification operation according to the sensing signal and the reference signal. The sensing signal and the reference signal form a differential signal pair. The driving circuit generates a fingerprint identification signal according to the sensing signal and the reference signal. A driving circuit and a fingerprint identification method are also provided.
