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 visible wavelength light at least partially through the display to illuminate an object, such as a fingerprint or a retina, in contact with or proximate to an outer surface of the display. Surface reflections from the object traverse the display stack and are received and an image of the object can be assembled.
