Claim 0:
1. An apparatus comprising:
an ultrasonic fingerprint sensor system including a plurality of ultrasonic sensor pixels disposed within one or more layer stacks, each layer stack having at least a corresponding piezoelectric layer and a corresponding electrode layer and each ultrasonic sensor pixel configured to generate a corresponding ultrasonic sensor signal responsive to that ultrasonic sensor pixel detecting passage of an ultrasonic wave therethrough;
a display system including at least one display, the display system including a plurality of ultrasonically sensitive display surfaces, each ultrasonically sensitive display surface associated with a different subset of display pixels of the display system and a different subset of the ultrasonic sensor pixels, wherein at least two of the ultrasonically sensitive display surfaces are not co-planar with each other; and
an ultrasonic transmitter that is not coextensive with the ultrasonically sensitive display surfaces and not part of any of the one or more layer stacks, the ultrasonic transmitter configured to transmit one or more ultrasonic waves responsive to receipt of one or more input signals, wherein the apparatus is defined by a plurality of rigid outermost surfaces that include the ultrasonically sensitive display surfaces.
