    Abstract: A brightness enhancement film includes a plurality of linear prisms disposed on a birefringent substrate. A light ray that enters the film from the substrate side and exits the film from the linear prisms side undergoes substantially a same phase retardation for mutually orthogonal polarization states while travelling within the film. The light ray exits the film at an angle from a normal to the substrate that is greater than 20 degrees.

    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.

    Abstract: An optical assembly includes a light directing film having an average effective transmission of at least 1.3, a light diffusing film having an optical haze of at least 5% and a plurality of spaced apart posts disposed and defining an air gap between the light directing and diffusing films. The posts are attached to a first major surface of the substrate and an opposing second end of each post is attached to the light diffusing film via a first adhesive layer. The first adhesive layer forms a meniscus at each post having an outer surface radius of at least 0.5 micrometers.

    Abstract: Example light management films including a plurality of tapered protrusions are described. In some examples, the disclosure relates to a film comprising a reflective polarizer layer and a plurality of tapered protrusions disposed on and tapering away from the reflective polarizer layer, where the tapered protrusions include at least one of a plurality of substantially conical shaped protrusions or a plurality of pyramidal shaped protrusions including at least four side faces. The plurality of tapered protrusions may be configured to reduce the divergence of incident light and redirect a majority of incident light propagating along a first direction to a second direction different from the first direction.
