Abstract: An electronic device and a fingerprint sensing control method thereof are provided. The electronic device includes a touch control circuit and a fingerprint sensing control circuit. The touch control circuit is coupled to the display panel. The touch control circuit performs touch detection on the display panel to obtain a finger press area corresponding to the finger on the display panel. The fingerprint sensing control circuit is coupled to the touch control circuit to obtain a finger press area. The fingerprint sensing control circuit is coupled to the display panel to perform a fingerprint sensing control on a display panel. The fingerprint sensing control circuit scans the finger press area on the display panel in a first direction during a first period and scans the finger press area in a second direction different from the first direction during a second period after the first period.

Abstract: An electronic device and a fingerprint sensing control method thereof are provided. A sensing region of a display panel is divided into a plurality of fingerprint zones. The electronic device determines at least one target fingerprint zone from the fingerprint zones according to a touched area. The electronic device scans the at least one target fingerprint zone for performing fingerprint sensing. The electronic device performs an accelerated reading operation. The accelerated reading operation includes: reading at least one sensing signal from the at least one target fingerprint zone; and skipping reading at least one of the fingerprint zones other than the at least one target fingerprint zone among the fingerprint zones.
