Abstract: A retroreflective article comprises (a) a retroreflective layer including a structured surface that is opposite a major surface, (b) a pressure sensitive adhesive that contacts at least a portion of the structured surface to form an optically inactive area that does not substantially retroreflect incident light and (c) at least one low refractive index layer forming an optically active area that retroreflects incident light; wherein the optically active area comprises about 25% or less of the structured surface.

Abstract: An optical film includes a microstructured surface having a plurality of irregularly arranged planar portions forming greater than about 10% of the microstructured surface. The microstructured surface may be configured such that, when the microstructured surface is placed on an emission surface of a lightguide with a first luminous distribution of light exiting the lightguide from the emission surface in a first plane perpendicular to the emission surface, the light emitted by the lightguide is transmitted by the microstructured surface at a second luminous distribution of the transmitted light in the first plane. The first luminous distribution includes a first peak making a first angle greater than about 60 degrees with a normal to the microstructured surface. The second luminous distribution includes a second peak making a second angle in a range from about 5 degrees to about 35 degrees with the normal to the microstructured surface.

Abstract: An optical film (210) includes a microstructured surface (211) comprising a plurality of prismatic structures (230), the microstructured surface (211) defining a reference plane (241-242) and a thickness direction (243) perpendicular to the reference plane; wherein the plurality of prismatic structures includes a plurality of facets (231), each facet having a facet normal direction forming a polar angle with respect to the thickness direction and an azimuthal angle along the reference plane, and wherein the microstructured surface has a surface azimuthal distribution of the plurality of facets that is substantially uniform, and wherein the microstructured surface has a surface polar distribution of the plurality of facets that has an off-axis peak polar distribution.

Abstract: A method for creating and using tradeable carbon credits with display devices comprising the steps of: (a) identifying a display component that provides greenhouse gas emission reductions in a display device while the display device is powered; (b) obtaining certification of tradeable carbon credits for greenhouse gas emissions reductions provided by the display component when the display device is powered; (c) providing the display component for use in a display device; and (d) receiving tradeable carbon credits over the course of the lifetime of the display device.

Abstract: A backlight (120) that includes a front reflector (130) and a back reflector (160) that form a hollow light recycling cavity (162) having an output surface (164) is disclosed. The front reflector includes at least four directional recycling films (132). The backlight also includes a semi-specular diffuser disposed between the front reflector and the back reflector, and one or more light sources (166) disposed to emit light into the light recycling cavity.
