  • Publication number: 20080113117
    Abstract: Disclosed herein are light diffusing films, methods of making the same and articles using the same. In one embodiment, a method of making a light-diffusing film comprises: mixing about 90 wt. % to about 99.999 wt. % of a powdered polycarbonate and about 0.001 wt. % to about 3 wt. % light-diffusing particles to form a mixture, wherein weight percents are based on a total weight of the light-diffusing film; melting the mixture to form a melt; and extruding the melt in the form of a sheet to form the light-diffusing film. The light-diffusing film comprises a hiding power of about 0 to 0.
