  • Patent number: 7824747
    Abstract: A light diffusing film for a back light display is described. The light diffusing film includes a unitary film consisting essentially of polycarbonate and a uniformly dispersed anti-static material in an amount sufficient to impart anti-static properties to the film. The anti-static material may comprise a fluorinated phosphonium sulfonate. The film may additionally include at least one textured surface for the low scattering of light. Alternatively, the film may additionally include a uniformly dispersed acrylic bulk scattering additive of particles having a mean particle size of from about 3 to about 10 microns and present in an amount from about 2 to about 7 percent by weight percent for the high scattering of light.
    Type: Grant

  • Publication number: 20060020075
    Abstract: A film comprising in admixture a thermoplastic resin component comprising a thermoplastic resin component and a glass having a refractive index within 0.04 of the thermoplastic resin component, wherein the film has a haze of less than about 20%, total transmittance of greater than about 70%, and a coefficient of thermal expansion of about 20 to about 80 um/m/° C. measured over a temperature range of 20 to 70° C. The films are of particular utility in optical applications such as light diffuser films.
