Abstract: An acoustic imaging system coupled to a sensing plate to define an imaging surface. The acoustic imaging system includes an array of piezoelectric acoustic transducers coupled to the sensing plate opposite the imaging surface and formed using a thin-film manufacturing process over an application-specific integrated circuit that, in turn, is configured to leverage the array of piezoelectric actuators to generate an image of an object at least partially wetting to the imaging surface.

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: A display may have an array of light-emitting pixels that display an image in an active area of the display. These light-emitting pixels may be visible light pixels such as red, green, and blue thin-film organic light-emitting diode pixels. The display may also have a border region that runs along a peripheral edge of the active area. The border region may be free of pixels that display image light, whereas the active area may be free of light detectors. A non-optical touch sensor such as a capacitive touch sensor may overlap the active area to gather touch input from the active area. The non-optical touch sensor may not overlap any portion of the border region. In the border region, an optical sensor formed from infrared light-emitting pixels and infrared light-sensing pixels or other optical sensing circuitry may serve as an optical touch sensor.

Abstract: An optical system is described. The optical system may include a sensor which may be in a mobile device. The optical system may use the same light source for imaging the display and for providing light to a sensor or sensor device. The optical system may be configured so that randomly polarized light will exit the device for viewing so that a user may view the display in any rotated orientation while wearing polarized eyewear. The optical system may further be configured to mitigate reflections in the mobile device from ambient light entering the system and from reflected and backscattered light from cross-contaminating the imaging light of the display.

Abstract: An apparatus for touch-sensing includes a light-emitting layer covered by a transparent layer and configured to illuminate a surface touching the transparent layer and to allow transmission of reflected light rays from the surface to underlying layers. The underlying layers include an optical coupling layer, a collimator layer and a pixelated image sensor. The optical coupling layer bends the reflected light rays to create oblique light rays. The collimator layer includes a number of apertures to collimate the received light rays. The pixelated image sensor senses the collimated oblique light rays.

Abstract: An input device outfitted with one or more ultrasonic transducers can determine the location of one or more objects in contact with the input device. For example, the input device can include one or more transducers disposed in a ring around the circumference of the input device or in an array of rings along the length of the input device. The ultrasonic transducers can be used to detect the position of the one or more touching objects in at least one dimension, for example. In some examples, the one or more ultrasonic transducers can produce directional ultrasonic waves.

Abstract: Systems and methods for through-display imaging. An optical imaging sensor is positioned at least partially behind a display and is configured to emit shortwave infrared light at least partially through the display to illuminate an object, such as a fingerprint, in contact with an outer surface of the display. Surface reflections from the object are received and an image of the object can be assembled.

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.
