    摘要: Embodiments include systems and methods for reducing visible artifacts such as Moiré, or interference, patterns, in displays. One embodiment includes a display device comprising a plurality of light modulators and a plurality of illumination elements configured to direct light to the light modulators. The directed light of the plurality of illumination elements collectively defines an nonuniformly varying pattern of light.

    摘要: In various embodiments described herein, a display device includes a front illumination device that comprises a light guide disposed forward of an array of display elements, such as an array of interferometric modulators, to distribute light across the array of display elements. The light guide may include a turning film to deliver uniform illumination from a light source to the array of display elements. For many portable display applications, the light guide comprises the substrate used in fabricating the display elements. The display device may include additional films as well. The light guide, for example, may include a diffuser and/or an optical isolation layer to further enhance the optical characteristics of the display.

    摘要: An illumination device includes a holographic film and a light source, such as a point light source. The point light source is positioned at an edge of the holographic film and has a light emitting face that faces the edge of the holographic film. The holographic film includes a hologram formed of diffractive refractive index structures. The density of the diffractive refractive index structures increases with increasing distance from the light source. Light is propagated from the light source through the holographic film, such as by total internal reflection. The diffractive refractive index structures turn the light, thereby causing the light to propagate out of the holographic film in a desired direction. In some embodiments, the light propagating out of the holographic film has a high uniformity across the surface of the holographic film.

The light in the second light guide is coupled into the first light guide using a small optical coupling element such as a turning mirror. In some embodiments the second light guide may comprise the backplate of the display device.

    摘要: An illumination apparatus includes a light bar, a plurality of indentations in the light bar on a first side of the light bar, and a contoured reflective surface including a plurality of protruding surface portions, such that the surface portions reflect light transmitted through sloping sidewalls of the indentations. The light bar has a first end for receiving light from a light source. The light bar includes material that supports propagation of the light along the length of the light bar. The turning microstructure is configured to turn at least a substantial portion of the light incident on the first side and to direct the portion of light out the second opposite side of the light bar. The protrusions on the contoured reflective surface and the indentations on the light bar can have complimentary shapes and/or aligned in certain embodiments.

    摘要: Light modulator displays may be illuminated using a light guide comprising diffractive optics that directs light onto the light modulators. The light guide may comprise, for example, a holographic light turning element that turns light propagating within the light guide onto the array of light modulators. In some embodiments, the holographic element has multiple holographic functions. For example, the holographic element may additionally collimate ambient light or diffuse light reflected form the light modulators.
