The present disclosure relates to a fingerprint sensor integrated type touch screen panel having at least one fingerprint/touch area and a plurality of touch areas. The touch screen panel includes a fingerprint/touch driving electrode group including a plurality of fingerprint/touch driving electrodes; a fingerprint/touch sensing electrode group including a plurality of fingerprint/touch sensing electrodes; a touch driving electrode group including a plurality of touch driving electrodes; a touch sensing electrode group including a plurality of touch sensing electrodes; and a touch IC configured to supply touch driving signals to the touch driving electrode group and the fingerprint/touch driving electrode group and obtain touch sensing data by sensing the touch sensing electrode group and some of the fingerprint/touch sensing electrodes in a touch sensing mode, and supply fingerprint driving signals to the fingerprint/touch driving electrodes and obtain fingerprint sensing data by sensing the fingerprint/touch sensing electrodes in a fingerprint sensing mode.
