[57] ABSTRACT
A light control material for providing autostereoscopic and dynamic images. The light control material is comprised of a light direction control optic which contains a pattern of bright zones and dark zones which provide light direction control, and a light focusing optic which contains a plurality of gradient refractive index lenses which provide light focusing control. The bright zones and dark zones and the gradient refractive index lenses are preferably formed in a single polymer layer. Interleaved image elements may generally be located anywhere between the light control optic and an observer. The light direction control optic in conjunction with the light focusing optic and the interleaved image elements produce the perception autostereoscopic depth, motion, or color change.
