Abstract: A fingerprint sensing apparatus having a large-area sensing mechanism is provided that includes at least three optical fingerprint sensing circuits and a processing circuit. The at least three optical fingerprint sensing circuits are configured to perform sensing within a plurality of sensing areas to obtain a plurality of sensed images, wherein each of the sensing areas corresponds to one of the optical fingerprint sensing circuits. The processing circuit is electrically coupled to the optical fingerprint sensing circuits to receive the sensed images and is configured to splice the sensed images together to form an integrated sensed image.

Abstract: A fingerprint detection device comprises a plurality of fingerprint sensing circuits and a processor. The plurality of fingerprint sensing circuits is corresponding to a plurality of sensing zones respectively. The processor is electrically coupled to the fingerprint sensing circuits through a shared transmission bus. The processor is configured to receive information of a touched area of each of the sensing zones, determine a transmission sequence according to the touched area of each of the sensing zones, and control the fingerprint sensing circuits to transmit sensing information of the corresponding sensing zones to the processor through the shared transmission bus according to the transmission sequence.
