Patent attributes
Provided is a light control film and displays incorporating same. In particular, provided are light control films comprising a light input surface and a light output surface opposite the light input surface. The light control films further comprise alternating transmissive and absorptive regions disposed between the light input surface and the light output surface. Each transmissive region has an index of refraction N1, and each absorptive region having an index of refraction N2, where N2-N1 is not less than−0.005. The light control films have an average pitch of successive absorptive regions of 0.070 mm or less. Light incident to the light input surface exits the light output surface with a maximum relative brightness ratio (RBR) in a direction perpendicular to the light output surface of 65 or greater, and exits the light output surface with an effective polar viewing angle (EPVA) of 45° or less.
