摘要： An illumination apparatus includes a light bar, turning microstructure disposed on a first side of the light bar, and a light guide panel disposed with respect to a second opposite side of the light bar. 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. A parameter of the turning microstructure changes with distance from the first end of the light bar. The light bar has a turning efficiency that determines the amount of light turned out of the light bar compared to the amount of light that continues to be guided within the light bar. The turning efficiency increases with distance from the first end of the light bar. The light guide panel is configured to receive light turned by the turning microstructure and directed out of the second opposite side of the light bar.

摘要： A method of fabricating an electromechanical device which comprises a step of etching a sacrificial layer with an etchant comprising a noble gas fluoride, e.g. xenon difluoride (XeF2). The efficiency of the etching process may be increased in various ways, and the cost of an etching process may be decreased. Unused etchant may be isolated and recirculated during the etching process. Etching byproducts may be collected and removed from the etching system during the etching process. Components of the etchant may be isolated and used to general additional etchant. Either or both of the etchant or the layers being etched may also be optimized for a particular etching process.

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.
