Abstract: Structured surfaces are described. In one embodiment, the structured surface comprises a plurality of structures having complement cumulative slope magnitude distribution (Fcc) such that at least 30, 40, 50, 60, 70, 80 or 90% of structures have a slope greater than 10 degrees; and less than 80% of the structures have a slope greater than 35 degrees. In other embodiments, the structures comprise peaks and valleys defined by a Cartesian coordinate system such that the peaks and valleys have a width and length in the x-y plane and a height in the z-direction and at least a portion of the peaks and/or valleys vary in height in the y direction and/or the x-direction by at least 10% of the average height. Articles and methods are also described.

Abstract: Films and articles are described comprising a microstructured surface having an array of peak structures and adjacent valleys. For improved cleanability, the valleys preferably have a maximum width ranging from 10 microns to 250 microns and the peak structures have a side wall angle greater than 10 degrees. The peak structures may comprise two or more facets such as in the case of a linear array of prisms or an array of cube-corners elements. The facets form continuous or semi-continuous surfaces in the same direction. The valleys typically lack intersecting walls. Also described are methods of making and methods of use. The microstructured surface of the article can be prepared by various microreplication techniques such as coating, injection molding, embossing, laser etching, extrusion, casting and curing a polymerizable resin; and bonding microstructured film to a surface or article with an adhesive.

Abstract: An optical component includes a substrate and a plurality of structures formed on a first major surface of the substrate and extending from the first major surface along a thickness direction of the optical component. The optical component can be assembled with another optical component to form a light control film. A light control film includes first and second optical components including respective pluralities of first and second structures formed on, and extending from, respective first and second substrates. The first and second optical components are assembled so that the first and second structures are disposed between the first and second substrates and interleaved to form a plurality of pairs of adjacent first and second structures. For each of at least some of the pairs, the adjacent first and second structures define an optical cavity therebetween substantially filled with a light absorbing material.

Abstract: A light redirecting film includes a first layer disposed on a second layer with structured major surfaces of the first and second layers facing each other. An optically reflective layer or a metal layer is disposed between the first and second layers. The first layer can be a hot melt adhesive layer and the second layer can be a polymeric layer. The first and second layers can be unitary layers. The first layer can be a first polymeric layer having a softening temperature T1 and the second layer can be a second polymeric layer having a softening temperature T2 greater than T1. Heating and/or applying pressure to the film changes an optical characteristic of the film by less than about 5%.

Abstract: Lamination transfer films and methods for transferring a structured layer to a receptor substrate. The transfer films include a carrier substrate having a releasable surface, a sacrificial template layer applied to the releasable surface of the carrier substrate and having a non-planar structured surface, and a thermally stable backfill layer applied to the non-planar structured surface of the sacrificial template layer. The sacrificial template layer is capable of being removed from the backfill layer, such as via pyrolysis, while leaving the structured surface of the backfill layer substantially intact.

Abstract: Variable index light extraction layers (100) that contain a plurality of microreplicated posts (120) are described. The variable index light extraction layers contain a plurality of microreplicated posts (120), a first region including a first lower-index substance (130) and a second region including a second higher-index substance (140). Optical films can use the variable index light extraction layers (100) in front lit or back lit display devices.
