Abstract:
Optical films used for 3D autostereoscopic displays include lenses on one surface of the optical film that are registered to prisms on the opposing surface of the optical film. The lenses may be a-cylindrical lenses or cylindrical, and the rotation of the lenses can vary with position on the surface of the optical film. The prisms may be contiguous or non-contiguous. The prisms of the optical film can have a pitch that is different from a pitch of the lenses, or the prism pitch can be substantially the same as the pitch of the lenses.
