Abstract
A light control material having a layer of emulsion, an inner optic, and a substrate. Image strips are formed in the emulsion. The inner optic provides illumination of the image strips as well as the light direction control needed to produce the perception of autostereoscopic depth, motion, or color change. The inner optic is comprised of a pattern of bright zones and dark zones. The inner optic has a constant period and the width of the bright zones is approximately equal to the width of the image strips. The field of view of the autostereoscopic or dynamic image may be altered by varying the widths of the bright zones and the image strips.
