Abstract

See full text

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, 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 controller; a receive layer disposed on a second side of the sensor glass layer, where the receive layer is electrically coupled to the controller; and a protective cover layer disposed on the receive layer.
