A method for driving a fingerprint sensing device including a fingerprint sensor including a plurality of scan lines and a plurality of initialization lines extending in a first direction and arranged in a second direction, a plurality of sensing lines extending in the second direction and arranged in the first direction, and a plurality of sensing pixels connected to the scan lines, the initialization lines, and the sensing lines and disposed in a matrix configuration, comprising:

• applying a disable-level initialization signal to b-numbered sensing pixel rows, and applying an enable-level initialization signal to a-numbered sensing pixel rows;
• while applying the initialization signal, applying an enable-level scan signal to one sensing pixel row in the b-numbered sensing pixel rows;
• and
• receiving 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 and
• wherein
• the sensing pixels respectively include:
• a reference capacitor including one electrode connected to a first node and another electrode connected to a corresponding initialization line from among the plurality of initialization lines,
• a touch capacitor including one electrode connected to the first node,
• a first transistor configured to output a sensing signal to a corresponding sensing line from among the sensing lines according to a voltage at the first node,
• a second transistor connected to a corresponding scan line from among the scan lines and configured to transmit the sensing signal to the sensing line, and
• a third transistor connected to the initialization line and configured to initialize the first node.
