Abstract: A display device has a visual display capable of providing an image and an ultrasonic sensor array attached to a backside component of the visual display. The ultrasonic sensor array may be an ultrasonic area array sensor. For example, the backside component may be a backlight, an optical waveguide, or a display TFT.

Abstract: A touch sensing system may include a pressure and force sensing device capable of sensing dynamic pressure or dynamic force applied to a piezoelectric sensing array. In such implementations, an applied force may be detected (and optionally recorded) during a period of time that the force is applied and changing. The force-sensing device may have a sufficiently high resolution to function as a fingerprint sensor. The touch sensing system may include one or more additional components capable of fingerprint sensing, such as an ultrasonic transmitter that allows the device to become an ultrasonic transducer capable of imaging a finger (or another object) in detail. The force-sensing device also may be capable of functioning as an ultrasonic receiver.
