Abstract
An electronic circuit adapted to process fingerprint data from a panel including touch sensors and fingerprint sensors is provided. The electronic circuit includes a first circuit, a second circuit and a control circuit. The first circuit is configured to receive touch sensing signals from the touch sensors. The second circuit is configured to receive fingerprint sensing signals corresponding to at least one fingerprint imprint from the fingerprint sensors via fingerprint sensing lines. The control circuit is configured to determine a fingerprint touch area according to the touch sensing signals, and select a subset of the fingerprint sensing lines to form a fingerprint sensing zone adapted for a fingerprint sensing operation and including at least one boundary based on the determined fingerprint touch area. The subset of fingerprint sensing lines is selected based on the at least one boundary of the fingerprint sensing zone. An electronic device and a method for sensing at least one fingerprint imprint from a panel are also provided.
