    摘要： 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.

    摘要： 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.

    摘要： An illumination system for a reflective display is particularly useful for microdisplays that use reflective displays. The light source and the reflective image display unit are mounted in a coplanar manner, thus permitting the light source and the display unit to be mounted on a single board, or even on a single substrate. The display unit may include a first light source directing light generally along a first axis and a reflective image display unit disposed with an optical axis substantially parallel to the first axis. A reflective polarizing film is disposed to direct light from the first light source to the reflective image light display unit.

    摘要： Methods for fabricating an optical film characterizable by a relationship between gain and thickness to prism pitch ratio (S/p) that varies cyclically are described. The thickness and the prism pitch of the optical film are selected based on the relationship between gain and S/p ratio, to obtain a desired gain. The optical film is formed having the S/p ratio that provides the desired gain.

    摘要： A light guide including a light guide body having a light re-directing side positioned opposite from a light output side. A plurality of elongate prisms are located adjacent the light output side of the light guide body. The prisms extend side-by-side relative to one another along lengths. The prisms include upper edges defining heights of the prisms. The upper edges extend along the lengths of the prisms. Each upper edge includes a plurality of edge segments having different magnitudes of slope. The light guide also includes a plurality of light extraction structures located adjacent the light re-directing side of the light guide body for reflecting light toward the light output side. The light extraction structures include elongated projections each having a plateau segment and first and second facets. The elongated projections are separated by lands that are recessed relative to the plateau segments. The first and second facets extend from the plateau segments to the lands.
