Abstract: Some disclosed implementations include an ultrasonic sensor stack and an acoustic resonator. The acoustic resonator may be configured to enhance ultrasonic waves transmitted by the ultrasonic sensor stack in an ultrasonic frequency range that is suitable for ultrasonic fingerprint sensors. In some examples, the acoustic resonator may include one or more low-impedance layers residing between a first higher-impedance layer and a second higher-impedance layer. Each of the one or more low-impedance layers may have a lower acoustic impedance than an acoustic impedance of the first higher-impedance layer or an acoustic impedance of the second higher-impedance layer. At least one low-impedance layer may have a thickness corresponding to a multiple of a half wavelength at a peak frequency of the acoustic resonator. The peak frequency may be within a frequency range from 1 MHz. to 20 MHz.

Abstract: An apparatus includes an ultrasonic sensor stack, a foldable display stack that includes a display stiffener, and an additional stiffener between the ultrasonic sensor stack and the foldable display stack. The additional stiffener forms an acoustic resonator with the display stiffener and an adhesive layer between the display stiffener and the additional stiffener in order to amplify transmission of ultrasonic waves transmitted by the ultrasonic sensor stack. The additional stiffener includes a material having a high modulus of elasticity, low density, and high acoustic impedance value. In some cases, the additional stiffener includes a metal, a ceramic, a glass, or a glass ceramic. The additional stiffener increases an overall stiffness and mechanical integrity of the apparatus so that a foam backer may be omitted from the ultrasonic sensor stack.

Abstract: Techniques for operating an ultrasonic sensor array, the ultrasonic sensor array disposed under a platen, include making a determination whether or not to recalibrate the ultrasonic sensor array based on whether a first screen protector disposed above the platen has been removed or replaced by a second screen protector; and recalibrating the ultrasonic sensor array, when the determination is to recalibrate the ultrasonic sensor array. In some cases, the techniques include prompting a user to indicate whether or not the screen protector has been changed or removed, and recalibrating the ultrasonic sensor array only after confirmation from the user.

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.

The method may involve determining, via the control system, a digit force or a digit pressure of the digit on the outer surface of the apparatus. The method may involve controlling, via the control system, the apparatus to provide a second prompt corresponding to the digit force or the digit pressure.
