Abstract: A luminance enhancement film having a built-in light diffusing structure. The support substrate incorporates a dispersion of particles for light diffusion. In accordance with the present invention, a separate particle layer is not required in addition to the support substrate layer. The particles are integrated in the unitary support substrate layer. In one aspect of the present invention, the particles are dispersed near at least one of the planar surfaces of the support substrate (i.e., the light input surface light output surface or both of the support substrate. All the particles may be embedded below the surface of the support substrate, or some of the particles may protrude above the surface of the support substrate. In one embodiment of the present invention, the support substrate contains particles that are dispersed only close to its surface and form protrusions at the surface (i.e., the particle dispersed surface is not smooth).

Abstract: This invention is directed to an improved thermoplastic molding composition having an admixture of thermoplastic polymer or blends thereof and a particular mineral additive having needle like particles and a high aspect ratio of length to diameter. The composition when molded with the final article has improved surface characteristics, even a Class A surface, a lower coefficient of thermal expansion, as well as other improved properties, particularly impact as determined by Dynatup testing. The mineral additive can range from 5 to 70 weight percent. The polymer portion can be a copolyetherimide ester, a copolyether ester, an aromatic polycarbonate, a rubber modified homopolymer, or copolymer of a vinyl aromatic monomer, a polyphenylene ether, a polyamide, and blends thereof or blends with other polymers. The preferred mineral additive is calcium meta silicate, also known as wollastonite.
