    Abstract: The present disclosure provides a light control film that is capable of transmitting light, or allowing a viewer to observe information, only within a viewing region centered around the normal (perpendicular line) to a surface. The light control film generally blocks information or light outside of this viewing region, and provides security in all directions including right-and-left and up-and-down of the film. The light control film includes a plurality of light-transmissive cavities that are surrounded by a light absorbing material, such that each of the plurality of cavities is optically isolated from adjacent cavities. Each of the light-transmissive cavities effectively block light which enters the cavity outside of a viewing (that is, cutoff) angle.

    Abstract: 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 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.

    Abstract: A light control film, and light collimating assemblies and liquid crystal displays incorporating such light control films are described. The light control film includes alternating transmissive and absorptive regions, where the refractive index of each transmissive region is greater than the refractive index of each absorptive region. The absorptive regions form interfaces at angles that are close to the perpendicular to the light control film. A portion of the incident light intercepting the absorptive region undergoes Total Internal Reflection, and is transmitted through the film. The axial brightness of light passing through the film is increased, the brightness is more uniform within the viewing angle, and the viewing cutoff angle is sharpened.
