    Abstract: An electronic device may include a display layer including light transmissive portions and non-transmissive portions. The electronic device may also include a palm biometric image sensor layer beneath the display layer and configured to sense an image of a user's palm positioned above the display layer based upon light reflected from the user's palm passing through the light transmissive portions of the display layer. The electronic device may further include a controller configured to capture image data from the user's palm in cooperation with the palm biometric image sensor layer and determine a surface distortion of the user's palm based upon the image data. The controller may also be configured to perform a biometric authentication of the user's palm based upon the image data and the surface distortion.

    Abstract: Acoustic touch and/or force sensing system architectures and methods for acoustic touch and/or force sensing can be used to detect a position of an object touching a surface and an amount of force applied to the surface by the object. The position and/or an applied force can be determined using time-of-flight (TOF) techniques, for example. Acoustic touch sensing can utilize transducers (e.g., piezoelectric) to simultaneously transmit ultrasonic waves along a surface and through a thickness of a deformable material. The location of the object and the applied force can be determined based on the amount of time elapsing between the transmission of the waves and receipt of the reflected waves. In some examples, an acoustic touch sensing system can be insensitive to water contact on the device surface, and thus acoustic touch sensing can be used for touch sensing in devices that may become wet or fully submerged in water.

    Abstract: Systems and methods for through-display imaging. A display includes an imaging aperture defined through an opaque backing. An optical imaging array is aligned with the aperture. Above the aperture, the display is arranged and/or configured for increased optical transmittance. For example, a region of the display above, or adjacent to, the imaging aperture can be formed with a lower pixel density than other regions of the display, thereby increasing inter-pixel distance (e.g., pitch) and increasing an area through which light can traverse the display to reach the optical imaging array.

    Abstract: An acoustic imaging system includes multiple transducers disposed to circumscribe a portion of substrate. An acoustic imaging system also includes a controller and an image resolver. The transducers convert electrical signals into mechanical energy and/or mechanical energy into electrical signals. The controller is adapted to apply an electrical signal to the transducers which, in response, induce a mechanical wave, such as a surface wave, into the circumscribed portion. The controller is also adapted to receive electrical signals from the transducers. The image resolver uses the electrical signals received by the controller in order to construct an image of an object in physical contact with the substrate.

    Abstract: An electronic device may include a substrate and a dielectric cover layer above the substrate. The electronic device may also include light emitting diodes (LEDs) carried by the substrate to direct light to the dielectric cover layer and optical image sensors carried by the substrate below the dielectric cover layer and adjacent the plurality of LEDs. Each optical image sensor may include at least one photodetector, a mask having at least one opening therein above the at least one photodetector, and an optical element above the mask and cooperating therewith to collimate light reflected from the dielectric cover layer to the at least one photodetector.
