Abstract: Optical films for redirecting light are described, and optical systems, such as display systems, incorporating such optical films are described. The optical film may include a first structured surface including a plurality of prismatic structures, and a second structured surface opposing the first structured surface and including a plurality of microstructures. An effective transmission of the optical film is not more than 1% less than a film with a comparable construction except for a smooth, non-structured second surface.

Abstract: A diffuser including opposing structured first and second major surfaces is described. The first major surface includes a first plurality of surface structures providing a uniform first haze. The second major surface includes a first portion adjacent an edge and a second portion adjacent the first portion. The first portion includes a first region and a second region between the first region and the second portion. The second major surface includes a second plurality of surface structures providing a uniform second haze over the second portion and providing a third haze in the first portion. The third haze in the first region is higher than the second haze, and the third haze in the second region is monotonically decreasing. The second portion has a surface area of at least 90 percent of a surface area of the second major surface.

Abstract: Optical diffusing films are made by microreplication from a structured surface tool. The tool is made using a 2-part electroplating process, wherein a first electroplating procedure forms a first metal layer with a first major surface, and a second electroplating procedure forms a second metal layer on the first metal layer, the second metal layer having a second major surface with a smaller average roughness than that of the first major surface. The second major surface can function as the structured surface of the tool. A replica of this surface can then be made in a major surface of an optical film to provide light diffusing properties. The structured surface and/or its constituent structures can be characterized in terms of various parameters such as optical haze, optical clarity, Fourier power spectra of the topography along orthogonal in-plane directions, ridge length per unit area, equivalent circular diameter (ECD), and/or aspect ratio.
