Abstract: An apparatus for fingerprint sensing includes a touch-display layer covered by a transparent layer. The touch-display layer can emit light to illuminate a finger surface touching the transparent layer. The touch-display layer is transparent to reflected light from the surface to underlying layers. The underlying layers include a collimator layer and a pixelated image sensor. The collimator layer can collimate the reflected light, and the pixelated image sensor can sense the collimated reflected light. The collimator can collimate the reflected light to enable a one-to-one imaging ratio between an area of the finger surface touching the transparent layer and an area of a corresponding image formed on the pixelated image sensor.

Abstract: An electronic device may include finger biometric sensing pixels and a processor capable of cooperating with the finger biometric sensing pixels to generate a series of finger images at a progressively slower capture rate as a finger settling increases over time from initial placement of a user's finger adjacent the finger biometric sensing pixels. The processor may also be capable of cooperating with the finger biometric sensing pixels to determine a quality factor for each image in the series thereof, and select at least one image from the series thereof for matching and based upon the quality factor.
