Abstract: A driver integrated circuit for fingerprint sensing, touch sensing and display driving and a driving method thereof are provided. The driver integrated circuit is adapted for driving a touch display panel with a fingerprint sensor. The driver integrated circuit includes a fingerprint sensing control circuit, a display driving circuit, and a display driving circuit. The fingerprint sensing control circuit drives the fingerprint sensor to perform a fingerprint sensing operation. The display driving circuit drives the touch display panel to perform a display operation. The touch sensing control circuit drives the touch display panel to perform a touch operation. The fingerprint sensing control circuit and the display driving circuit have a first direct communication therebetween so as to facilitate at least one of the fingerprint sensing operation and the display operation.

Abstract: A fingerprint identification device and method are provided. The fingerprint identification device includes a touch-sensing panel, a fingerprint sensor, and a processing circuit. The fingerprint sensing area of the fingerprint sensor is located in the touch-sensing area of the touch-sensing panel. The processing circuit senses the touch area of an object in the touch-sensing area via the touch-sensing panel when the object contacts the touch-sensing area of the touch-sensing panel. The processing circuit senses the fingerprint of the object via the fingerprint sensor to obtain a fingerprint template. The processing circuit determines the finger attribute of the object based on the physical characteristics of the touch area. The processing circuit selects the registered template related to the finger attribute from a plurality of registered templates according to the finger attribute, so as to perform fingerprint matching on the fingerprint template.
