Abstract:
1. A display comprising: a light-modulating array comprising a plurality of light-modulating elements and a substrate, the substrate on a side of the light-modulating elements, said light-modulating elements including movable reflective surfaces and static reflective surfaces that define active reflector areas of the light-modulating array spaced apart by substantially non-reflective portions; and an optical layer on said side of the light-modulating elements, the optical layer including a plurality of optical elements separated by gaps, wherein the gaps between the optical elements are above the active reflector areas and the optical elements are above the substantially non-reflective portions, the optical elements being configured to re-direct light propagating from above the optical layer and the substrate and incident on the optical elements into the active reflector areas.
