Abstract:
An electronic device, and a method for performing fingerprint sensing control on a display panel are provided. A sensing region of the 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 touch location, wherein the fingerprint zones are coupled to a plurality of scanning groups, each of the scanning groups comprises one or more scanning lines, the at least one target fingerprint zone is coupled to a first scanning group and a second scanning group other than the first scanning group among the plurality of scanning groups. The electronic device scans the first scanning group with a first speed, and scans the second scanning group with a second speed higher than the first speed or skips scanning the second scanning group.
