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.
Claims20
A light control material for displaying autostereoscopic or dynamic images formed of a series of image elements, said light control material comprising:
- a plurality of focusing elements;
- and
- light control optics having dark zones and bright zones, said dark zones and bright zones arranged in a predetermined pattern, and wherein there are a plurality of said focusing elements associated with each image element of the series of image elements, and wherein said dark zones and bright zones cause light to be directed through all of the focusing elements associated with a particular image element in the same direction such that an observer is provided with a view of an autostereoscopic or dynamic image.
