摘要： This disclosure provides systems, methods and apparatus, including a display device that includes an overlying holographic film. In one aspect, the holographic film includes a hologram that is configured to turn light incident on the film. The light is turned towards the display device at desired angles. The display can be formed of interferometric modulators and the turned light can be reflected off the display, and towards a viewer, to form an image. For light that is incident on the film at angles outside of a view cone, the holographic film is provided with holographic light turning features that turn this light so that it is reflected off the display at angles within a view cone of the display.

摘要： The present disclosure provides systems, methods and apparatus to produce a plurality of virtual light sources and at least partially collimate light. In one aspect, a manifold to collimate light can produce a plurality of virtual light sources used to inject light into a light guide for illuminating a display. The manifold can be formed of optically transmissive material and can have a backside for receiving light from a light source and a front wall, opposite the backside, for outputting light. The front wall can include first and second output portions separated by a non-light emitting area, each of the output portions providing a separate virtual light source. The upper, bottom, and side walls of the manifold can extend along a curve from the backside to the front wall and can be configured to collimate light propagating in directions extending out of the plane of the light guide.

摘要： In various embodiments described herein, a display device includes a front illumination apparatus that comprises a first 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 panel is edge illuminated by a light source positioned behind the array display elements. The light from such a light source is coupled to a second light guide disposed behind the array of display elements and positioned laterally with respect to the light source. 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.
