Abstract
Abstract A light control material includes a two-layer optical system for producing autostereoscopic and dynamic images in thin-film materials. The first layer comprises focusing optics which have a plurality of focusing elements. These elements may consist of refractive optics, binary optics, or mixed optics. The second layer comprises light control optics having dark zones and bright zones for providing directional control of light through the focusing optics. The bright zones may be comprised of a light transmissive material, or the light control optics may include a reflective layer for reflecting light at the bright zones. The dark zones may be formed by using an opaque material, preferably pigmented ink, on a substrate.
