Abstract:
Light control films comprise a light input surface and alight output surface opposite the light input surface and alternating transmissive regions and absorptive regions disposed between the light input surface and the light output surface. The absorptive regions have an aspect ratio of at least 30 and are canted in the same direction. The alternating transmissive regions and absorbing regions have a maximum relative transmission at a viewing angle other than 0 degrees.
