Electronic device and method for performing fingerprint sensing control

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.

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.
