Abstract: Disclosed are methods, devices, apparatuses, and systems for an under-display ultrasonic fingerprint sensor. A display device may include a platen, a display underlying the platen, and an ultrasonic fingerprint sensor underlying the display, where the ultrasonic fingerprint sensor is configured to transmit and receive ultrasonic waves via an acoustic path through the platen and the display. A light-blocking layer and/or an electrical shielding layer may be provided between the ultrasonic fingerprint sensor and the display, where the light-blocking layer and/or the electrical shielding layer are in the acoustic path. A mechanical stress isolation layer may be provided between the ultrasonic fingerprint sensor and the display, where the mechanical stress isolation layer is in the acoustic path.

Abstract: Embodiments of an ultrasonic button and methods for using the ultrasonic button are disclosed. In one embodiment, an ultrasonic button may include an ultrasonic transmitter configured to transmit an ultrasonic wave, a piezoelectric receiver layer configured to receive a reflected wave of the ultrasonic wave, a platen layer configured to protect the ultrasonic transmitter and the piezoelectric receiver layer, a first matching layer configured to match an acoustic impedance of the platen layer with an acoustic impedance of ridges of a finger, and an ultrasonic sensor array configured to detect the finger using the reflected wave.

Abstract: Un dispositivo de sensor de huellas digitales incluye un sustrato del sensor, una pluralidad de circuitos del sensor sobre una primera superficie del sustrato del sensor, y una capa de transceptor situada sobre la pluralidad de circuitos del sensor y la primera superficie del sustrato del sensor. La capa de transceptor incluye una capa piezoeléctrica y un electrodo del transceptor posicionado sobre la capa piezoeléctrica. La capa piezoeléctrica y el electrodo del transceptor están configurados para generar una o más ondas ultrasónicas o para recibir una o más ondas ultrasónicas. El dispositivo de sensor de huellas digitales puede incluir una tapa acoplada al sustrato del sensor y una cavidad formada entre la tapa y el sustrato del sensor. La cavidad y el sustrato del sensor pueden formar una barrera acústica.

Abstract: A fingerprint sensor device includes a sensor substrate, a plurality of sensor circuits over a first surface of the sensor substrate, and a transceiver layer located over the plurality of sensor circuits and the first surface of the sensor substrate. The transceiver layer includes a piezoelectric layer and a transceiver electrode positioned over the piezoelectric layer. The piezoelectric layer and the transceiver electrode are configured to generate one or more ultrasonic waves or to receive one or more ultrasonic waves. The fingerprint sensor device may include a cap coupled to the sensor substrate and a cavity formed between the cap and the sensor substrate. The cavity and the sensor substrate may form an acoustic barrier.
