摘要： Light modulator displays may be illuminated using a light guide comprising diffractive optics that directs light onto an array of light modulators. A holographic light turning element may be included with the light guide to turn light propagating within the light guide onto the light modulators. In some embodiments, the holographic element is configured to distribute a substantially uniform amount of light across the array of modulators. The holographic element may, for example, have a turning efficiency that changes along the length of the holographic element. A holographic element can also be used to function as a light bar. Such a holographic element may receive light from a light source such as a light emitting diode and distribute the light along a light guide disposed in front of an array of light modulators.

摘要： Various embodiments of a display device described herein include an optical propagation region (97), at least one optical loss structure (93), an optical isolation layer (95), and a plurality of display elements (91). The propagation region includes a light guide in which light is guided via total internal reflection and turning features configured to redirect the light out of the propagation region. The loss structure would disrupt the total internal reflection of at least some of the light guided within the propagation region if disposed directly adjacent thereto. The optical isolation layer includes a non-gaseous material between the propagation region and the loss structure, and is configured to increase an amount of light that is totally internal reflected in the propagation region. The plurality of display elements are positioned to receive the light redirected out of the propagation region. The loss structure is positioned between the plurality of display elements and the propagation region.

摘要： Modulator devices are selectably adjustable between at least two states, wherein the transmission and/or reflection of particular wavelengths of light are modified. Certain modulator devices are substantially uniformly adjustable over a wide range of wavelengths, including visible and infrared wavelengths. Other modulator devices are adjustable over visible wavelengths without significantly affecting infrared wavelengths. In addition, the modulator devices may be used in conjunction with fixed thin film reflective structures.

摘要： An illumination apparatus includes a light bar having 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. Turning microstructure is disposed on a first side of the light bar. The turning microstructure is configured to turn a substantial portion of light incident on the first side and to direct the portion of the light out a second opposite side of the light bar. A light guide panel is disposed with respect to a second opposite side of the light bar to receive the light turned by said turning microstructure and directed out of the second opposite side of the light bar. An optical coupler has an input surface and an output surface. The input surface is disposed to receive the light directed out of the second opposite side of the light bar. The output surface is disposed to couple light from the optical coupler into the light guide panel. The output surface of the optical coupler is tapered.
