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: Example light management films including a plurality of tapered protrusions are described. In many embodiments, a film includes a reflective polarizer layer and a plurality of tapered protrusions disposed on and tapering away from the reflective polarizer layer. At least one tapered protrusion in the plurality of tapered protrusions has a first lateral cross-section at a first location along a height of the tapered protrusion and a second lateral cross-section at a second location along the height of the tapered protrusion. The first cross-section has a first shape and the second cross-section has a different second shape.
