Abstract:
A fingerprint sensing device includes: a fingerprint sensor including scan lines and initialization lines extending in a first direction and arranged in a second direction, sensing lines extending in the second direction and arranged in the first direction, and sensing pixels connected to the scan lines, the initialization lines, and the sensing lines and disposed in a matrix configuration; a scan driver configured to apply an enable-level initialization signal to a-numbered sensing pixel rows while applying a disable-level initialization signal to b-numbered sensing pixel rows, and applying an enable-level scan signal to one sensing pixel row in the b-numbered sensing pixel rows; and a sensing driver configured to receive a sensing signal from the sensing pixel row to which the scan signal is applied through the sensing lines, wherein the a and b are positive numbers that are greater than 2.
