Claim 11:
12. A method for performing fingerprint sensing control on a display panel, wherein the display panel comprises a region divided into a plurality of fingerprint zones, the method comprising:
determining 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;
scanning the first area with at least one clock signal; and
scanning the second area with the at least one clock signal or skipping scanning the second area, wherein the at least one clock signal is set at a first frequency when the first area is scanned, and the at least one clock signal is set at a second frequency higher than the first frequency when the second area is scanned.
