Abstract: A fingerprint sensor is described that includes a thin protective cover layer on a sensor glass layer with receive circuitry between the thin protective cover layer and the sensor glass layer. In an implementation, a fingerprint sensor assembly includes a controller; a metal layer configured to be electrically coupled to the controller; a transmit layer electrically connected to the metal layer and the controller; a sensor glass layer including at least one through-glass via, where the transmit layer is disposed on a first side of the sensor glass layer, and where the transmit layer is electrically coupled to the at least one through-glass via; a receive layer disposed on a second side of the sensor glass layer, where the receive layer is electrically coupled to the at least one through-glass via; and a protective cover layer disposed on the receive layer.

Abstract: In embodiments, an apparatus includes a controller configured to operatively couple to a sensor (e.g., a touch panel sensor, a fingerprint sensor). The sensor includes a plurality of drive electrodes and a plurality of sense electrodes. Nodes are formed at the intersections of the plurality of drive electrodes and the sense electrodes. The controller includes output circuitry operatively coupled to the plurality of drive electrodes. The output circuitry is configured to generate unique drive signals to drive corresponding drive electrodes of touch panel sensor. The touch panel controller also includes input circuitry operatively coupled to the sense electrodes. The input circuitry is configured to measure mutual-capacitance formed at each intersection of the plurality of drive electrodes to create an image of one or more objects proximate to the sensor.
