Claim 16:
17. A method for performing fingerprint sensing control on a display panel, wherein the display panel comprises a sensing region divided into a plurality of fingerprint zones, the method comprising:
determining 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, 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;
scanning the first scanning group with a first speed; and
scanning the second scanning group with a second speed higher than the first speed or skipping scanning the second scanning group.
