Abstract:
Disclosed is a fingerprint sensor integrated type touch screen device that includes a touch screen having at least one fingerprint & touch area and a plurality of touch areas, each touch area including Tx electrode lines of a first group crossing Rx electrode lines of the first group, and touch sensors at crossings of the Tx electrode lines of the first group and the Rx electrode lines of the first group; and a touch integrated circuit (IC) that supplies a sensor driving signal of a same phase to the Tx electrode lines of the first group, groups first effective Rx channels of the Rx electrode lines of the first group as a bundle, and simultaneously senses the first effective Rx channels through a first touch sensing part, wherein first ineffective Rx channels of the Rx electrode lines of the first group are electrically disconnected from the first touch sensing part.
