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.

Diffuser for flat panel display

A light-diffusing film comprises about 90 wt. % to about 99.999 wt. % polycarbonate, wherein the polycarbonate comprises a yellowness index of about 0.8 to about 1.5 as measured in accordance with ASTM E313-73 (D1925); about 0.001 wt. % to about 3 wt. % light-diffusing particles; wherein weight percents are based on a total weight of the light-diffusing film; and wherein the light-diffusing film comprises a light transmission of about 45% to about 65% as measured in accordance with ASTM D1003-00, and a hiding power of 0 to about 0.5.

Light-diffusing films, backlight display devices comprising the light-diffusing films, and methods of making the same

A light collimating and diffusing film and a method for making the film are provided. The film includes a plastic layer having a first side and a second side opposite the first side and at least a first peripheral edge. The first side has a first textured surface, wherein between 7 to 20 percent of slope angles on the first textured surface proximate a first axis has a value between zero and five degrees. The first axis is substantially parallel to the first peripheral edge. The plastic layer collimates light propagating therethrough.
