Abstract

The present invention provides a method of a control circuit for controlling a fingerprint sensing operation of a display panel. The fingerprint sensing operation includes a reset operation, an exposure operation and a sample operation. The method includes steps of: performing the reset operation, the exposure operation and the sample operation of a fingerprint sensing cycle during a display frame interval in which a polarity of display data voltage on the display panel remains unchanged; and adjusting an exposure time of the exposure operation to be within the display frame interval.
