Abstract:
An electronic device, a fingerprint sensing control method and a fingerprint scanning control method are provided. A sensing region of a display panel is divided into a plurality of fingerprint zones. The electronic device determines at least one target fingerprint zone from the fingerprint zones according to a touched area. The electronic device scans the at least one target fingerprint zone to control the at least one target fingerprint zone for performing fingerprint sensing. The electronic device performs an accelerated scanning operation. The accelerated scanning operation includes: setting a scanning speed corresponding to at least one target scanning group coupled to at least the touched area to a first speed; and setting a scanning speed corresponding to one or more scanning groups other than the at least one target scanning group to a second speed higher than the first speed.
