Abstract:
Example light management films including a plurality of tapered protrusions are described. In some examples, the disclosure relates to a film comprising a reflective polarizer layer and a plurality of tapered protrusions disposed on and tapering away from the reflective polarizer layer, where the tapered protrusions include at least one of a plurality of substantially conical shaped protrusions or a plurality of pyramidal shaped protrusions including at least four side faces. The plurality of tapered protrusions may be configured to reduce the divergence of incident light and redirect a majority of incident light propagating along a first direction to a second direction different from the first direction.
