ELECTRONIC CIRCUIT HAVING FINGERPRINT SENSING FUNCTION AND METHOD FOR SENSING FINGERPRINT IMAGE

摘要

An electronic circuit adapted to drive a panel including a plurality of fingerprint sensing zones is provided. The electronic circuit includes a fingerprint sensing circuit. The fingerprint sensing circuit is configured to determine at least one of the fingerprint sensing zones to perform a fingerprint sensing operation according to a reference point of a touch area and receive a fingerprint sensing signal corresponding to fingerprint sensing data from the at least one of the fingerprint sensing zones. The fingerprint sensing circuit determines whether to rearrange the fingerprint sensing data according to the number of the fingerprint sensing zones determined to perform the fingerprint sensing operation. In addition, an electronic device and a method for sensing a fingerprint image are also provided.
