Method of performing touch sensing and fingerprint sensing simultaneously and electronic device and system using the same
Abstract:
An electronic device, capable of performing a touch sensing operation and a fingerprint sensing operation simultaneously, is provided. The electronic device comprises a touch sensing control circuit; and a fingerprint sensing control circuit; wherein the touch sensing control circuit senses a first touch on a sensing region of a panel, and the touch sensing control circuit provides a first location information corresponding to the first touch; wherein a fingerprint region is determined in the sensing region according to the first location information, and the fingerprint region encompasses a location of the first touch; wherein the fingerprint sensing control circuit performs the fingerprint sensing operation on the fingerprint region during a first sensing time, and the electronic device performs the touch sensing operation on the sensing region except the fingerprint region during the first sensing time.
