Claim 0:
1. An electronic device for performing fingerprint sensing control on a display panel, wherein the display panel comprises a region divided into a plurality of fingerprint zones, the electronic device comprising:
a fingerprint sensing control circuit, configured to be coupled to the display panel to:
determine at least one target fingerprint zone from the plurality of fingerprint zones according to a touch location, wherein the at least one target fingerprint zone comprises a first area and a second areas,
wherein the first area comprises a touch area corresponding to the touch location in the at least one target fingerprint zone and the second area comprises an area other than the touch area in the at least one target fingerprint zone;
provide a clock to the display panel for scanning the at least one target fingerprint zone;
scan the first area with the clock set at a first frequency; and
scan the second area with the clock set at a second frequency higher than the first frequency or skip scanning the second area.
