Patent ID: 8605960

Claim:
A fingerprint sensing module for a touch screen device, comprising: a substrate; a sensor having at least one linear sensor array attached to the substrate, the sensor being operable to capture portions of a fingerprint image as a finger is slid over the sensor; wherein the sensor is disposed adjacent to a perimeter edge of a touch screen of the touch screen device; a light source for illuminating an area of the finger; a motion detector comprised of a capacitive sensing element disposed within the touch screen of the touch screen device; wherein the motion detector is configured to detect finger movement as the finger is slid over an upper surface of the touch screen; and an image processor attached to the substrate and coupled to the sensor and the motion detector for processing at least two captured portions of the fingerprint image and further generating a processed fingerprint image in accordance with the finger movement determined by the motion detector; an optical lens system for directing light to the finger and for directing reflected light towards the sensor, wherein the optical element comprises a lens and a light guide that each has an upper surface that is co-planar with the upper surface of the touch screen.
