Abstract
Screens having unique optical properties are produced according to the invention by crosslinking and stretching, or otherwise deforming, a sheet of light-diffusing material having symmetrical light diffusion characteristics under conditions sufficient to induce asymmetry. Screens made from the asymmetric light diffusing materials described herein exhibit enhanced brightness and clarity. Utilizing the present methods, optical materials having a desired view angle or improved optical characteristics can be achieved.
