Abstract
Disclosed is a device for optical sensing, comprising: a display comprising a transparent substrate and a plurality of light emitters disposed above the transparent substrate; a transparent cover layer disposed above the display, wherein a top surface of the transparent cover layer provides an input surface for sensing an input object; and, an angled filter disposed below the transparent substrate of the display, wherein the angled filter is configured to allow light within a tolerance angle of an acceptance angle to pass through the angled filter, wherein the acceptance angle is centered around a non-zero angle relative to a normal of the input surface.
