  • 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%.
    Type: Grant
    Filed: November 24, 2015
    Date of Patent: April 18, 2017

  • 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.
