Abstract
An optical system is disclosed and includes an optical sensor configured to receive light and form an image. The optical system further includes a microlens film including a structured first major surface opposite a second major surface, the structured first major surface includes a regular array of spaced apart microlenses arranged across a width and a length of the microlens film and each microlens has an effective imaging area and configured to form an image onto the optical sensor. A light absorbing layer is disposed on the array of spaced apart microlenses and reduces the effective imaging area of each microlens by at least 10%. A display panel, the optical sensor, the microlens film and the display plane are substantially co-extensive with each other along the width and length of the microlens film.
