Abstract: An optical system comprises a lightguide having an elongated recess formed therein. The recess divides the lightguide into a first lightguide section a second larger lightguide section. Light extractors are disposed in the second, but not the first, lightguide section for extracting light that would otherwise propagate within and along the second lightguide section via total internal reflection (TIR). The depth of the recess varies along its length. The inclusion of a recess having a depth that varies along its length provides design flexibility in the number and location of light source(s) used by the optical system.

Abstract: A display system including a lightguide and first and second reflective layers disposed on opposite sides of the lightguide is provided. The lightguide has opposing first and second major surfaces and includes a light extraction pattern for extracting light that would otherwise be confined and propagate within the lightguide primarily by total internal reflection. Light extracted by the light extraction pattern exits the lightguide through at least one of the first and second major surfaces of the lightguide. Each of the first and second reflective layers has an average specular reflectance of at least 50% in a predetermined wavelength range. The light extraction pattern may be repeatedly imaged by the first and second reflective layers to produce three-dimensional stacked images of the light extraction pattern.

Abstract: Provided compositions, films, and methods impart a low-surface energy surface to a polyurethane layer whereby contaminants to bead up on the surface to dramatically facilitate removal. At the same time, the provided articles retain excellent clarity and processibility for use in surface protection applications. Compositions having these advantageous properties derive from reacting a primary polyisocyanate; a monohydroxyl polydimethylsiloxane present in a suitable amount; and a polyol selected from the group consisting of: a caprolactone polyol, polycarbonate polyol, a polyester polyol, acrylic polyol, polyether polyol, polyolefin polyol, and mixtures thereof.
