  • Publication number: 20190094418
    Abstract: Optical films for redirecting light are described, and optical systems, such as display systems, incorporating such optical films are described. The optical film may include a first structured surface including a plurality of prismatic structures, and a second structured surface opposing the first structured surface and including a plurality of microstructures. An effective transmission of the optical film is not more than 1% less than a film with a comparable construction except for a smooth, non-structured second surface.

  • Patent number: 10156661
    Abstract: An optical film having a structured surface is described. At least 90% of the structured surface has a slope magnitude that is less than about 5 degrees. The optical film may have an optical haze of less than about 10% and an optical clarity of less than about 50%, or may have an optical haze of less than about 7.5% and an optical clarity of less than about 60%, or may have an optical haze of less than about 3% and an optical clarity of less than about 65%.

  • Patent number: 9625640
    Abstract: Optical films, optical stacks including the optical films, and display systems including the optical films are described. The optical film includes a first major surface that may include a plurality of first microstructures that extend along a first direction. The optical film also includes a second major surface that is opposite to the first major surface and includes a plurality of second microstructures. The second major surface has an optical haze that is not greater than about 3% and an optical clarity that is not greater than about 85%.

  • Patent number: 8657472
    Abstract: A light redirecting film (100) includes a first major surface (110) that includes first microstructures (150) that extend along a first direction and a second major surface (120), which may form part of a matte layer, the second major surface being opposite to the first major surface and including second microstructures (160). The second major surface has an optical haze that is not greater than about 3% and an optical clarity that is not greater than about 85%. The light redirecting film has an average effective transmission that is not less than about 1.75. The light redirecting film (100) may comprise particles. The second microstructures may have a slope distribution.
