Classification: CPC G | IPC G

Claim 6:
7. An electronic device, comprising:
a fingerprint sensing control circuit, configured to be coupled to a display panel to perform fingerprint sensing control on the display panel, wherein the display panel is divided into a plurality of fingerprint zones and the fingerprint zones are coupled to a plurality of scanning groups, each of the scanning groups comprises one or more scanning lines, and the fingerprint sensing control circuit is configured to:
determine at least one target fingerprint zone from the fingerprint zones according to a touch location, wherein 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, wherein the first scanning group crosses a touch area corresponding to the touch location in the at least one target fingerprint zone and the second scanning group crosses an area other than the touch area in the at least one target fingerprint zone;
scan the first scanning group with a first speed; and
scan the second scanning group with a second speed higher than the first speed or skip scanning the second scanning group.
