Abstract: A film for a screen has a light transmitting substrate and a plurality of structures disposed on the substrate. An optical material at least partially fills cavities between the structures. A method of forming a film includes providing a light transmitting substrate having a plurality of structures disposed thereon and at least partially filling the cavities therebetween with an optical material.

Abstract: Described are multilayer optical composites including a first layer having an index of refraction n1, an ith layer having an index of refraction ni greater than n1, and one or two or more intermediate layers between the first layer and the ith layer, wherein the indices of refraction of the intermediate layers are between n1 and ni, and the index of refraction of each intermediate layer increases in the order of position of each layer from the first layer.

Abstract: In one embodiment, the invention is directed toward an apparatus that includes a first layer and a second layer attached with one another via sets of fastening elements formed on the layers. The fastening elements may comprise hook-like elements that engage one another in an interlocking arrangement to attach the layers, or alternatively, the fastening elements may take any form envisioned by a designer. In any case, the apparatus may also form a light guide that can be illuminated with a light source to transmit light by total internal reflection (TIR).

Abstract: Color-stable, pigmented optical bodies comprising a single or multiple layer core having at least one layer of a thermoplastic polymer material. The thermoplastic polymer material has dispersed within it a particulate pigment. The optical bodies generally possess high clarity and low haze and exhibit a transmission of light within a wavelength band of interest within the visible spectrum of from about 10 to about 90 percent.

Abstract: In a multilayer dielectric reflector, treating the surface of the reflector selectively increases the amount of light transmitted through the reflector. Various surface treatments can be used to permit light to transmit through the reflector that would otherwise be reflected by the reflector. In one such reflector, different portions of the surface have different coupling efficiencies for coupling light having a high propagation angle into the multilayer reflector. Those portions having higher coupling efficiencies on each side of the reflector have a higher degree of transmission.
