    Abstract: An optical film structure for backlit displays having two films, both in prisms up configuration. The first film, closer to the light guide, has an array of generally symmetric 90-degree prisms facing the viewer. The second film, farther from the light guide, has an array of generally asymmetric prisms facing the viewer, with one face of the prisms inclined at about 45 degrees and the other face generally perpendicular to the plane of the backlight. The prisms of the first and second films may have an azimuthal angle between them, and may have different pitches from each other. The film structure recycles a portion of the light from the light guide, thereby helping to increase uniformity over the area of the display. The film structure also compresses the light emerging from the light guide, thereby providing a more sharply peaked brightness distribution for the viewer.

    Abstract: An illumination system includes a light guide for distributing light. Extraction structures are provided to uniformly extract light from the light guide. The structures extract more light out of the light guide when light is propagating in the light guide in a direction toward the light input area than when light is propagating in the light guide in a direction away from the light input area.

    Abstract: Shaped refractive articles having compound curved surfaces enable a light source to provide substantially uniform illumination of a linear or planar target. The refractive articles can comprise an input edge or face and an output edge or face, the input edge or face having at least one shaped notch or cavity that can at least partially envelop a light source, wherein the notch or cavity has at least two oppositely signed curved portions shaped to provide substantially uniform illumination of a target by the source. The articles can also be optically coupled to and at least partially envelop a light source, and can have an output edge or surface having at least two oppositely signed curved portions shaped to provide substantially uniform illumination of a target region by the source. The shaped articles can be used in, for example, lighting devices, frontlights, backlights and electronic displays.

    Abstract: A wedge-shaped light extractor having a light-redirecting surface with a plurality of projections having a riser segment, a plateau segment, and a facet segment, with land segments flanking the projections. The projections improve extraction efficiency, thereby facilitating use of available light from a light source.

    Abstract: The present disclosure is directed to optical devices including a light source and an optical film having a first surface disposed to receive light from the light source and a second surface facing away from the light source. The second surface includes a two-dimensional array of closely packed substantially hemispherically-shaped structures. In some implementations of the present disclosure, the optical film further includes a substrate portion having an optical characteristic different from optical characteristics of the second surface comprising the two dimensional array.
