  • Publication number: 20220011474
    Abstract: Light control films have a pattern applied to it. The light control film has a plurality of spaced apart first grooves in an optical medium. Each first groove has a closed bottom. Some of the first grooves are partially filled with a light absorbing first material that absorbs light of a predetermined wavelength range of from 400 to 2000 nm. The light absorbing first material defines an unfilled void region inside the first groove extending from a bottom surface of the light absorbing first material to the closed bottom of the first groove.

  • Patent number: 10663630
    Abstract: Light control films are provided that confine light transmitted therethrough to be within a 360° view region and block light outside of this view region. The light control films can provide security in all directions including right-and-left and up-and-down of the films, without compromising light transmittance compared to one-dimensional light control films. The light control films include an array of light transmissive, tapered posts and absorptive regions disposed between the posts.

  • Patent number: 9684119
    Abstract: Flexible unitary lightguide and a method of making the same are disclosed. The lightguide includes a structured input side that includes a first pattern having smaller features superimposed on a second pattern having larger features. The lightguide further includes a structured top surface that includes a first region and a different second region. The first region includes a plurality of discrete light extractors for extracting light that propagates within the flexible unitary lightguide by total internal reflection. The second region includes a taper portion for directing light from the structured input side to the first region. The light extractors form a periodic array that has a first period along the length of the flexible unitary lightguide.
