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: A system includes a first group of transmit electrodes configured to be driven from a first side of a capacitive touch panel and a second group of transmit electrodes configured to be driven from a second side of the panel. The system also includes receive electrodes and a controller operatively coupled with the transmit electrodes and the receive electrodes. The controller is operable to dynamically configure the transmit electrodes and the receive electrodes to compensate for phase delays introduced by driving the transmit electrodes from different sides of the panel. A method includes driving a first group of transmit electrodes from a first side of a capacitive touch panel, driving a second group of transmit electrodes from a second side of the panel, and dynamically configuring the transmit electrodes and receive electrodes to compensate for phase delays introduced by driving the transmit electrodes from different sides of the panel.
