Kind Code:
B2
Abstract:
In one aspect, the invention provides a light control film having an indicium visible at a range of viewing angles. The light control film comprises a light input surface and a light output surface opposite the light input surface. The control film further comprises alternating transmissive and absorptive regions disposed between the light input surface and the light output surface. Each absorptive region has a height and a length, wherein the heights of the absorptive regions corresponding to the indicium are different than the heights of the absorptive regions that surround the absorptive regions corresponding to indicium.
