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.

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： This disclosure provides systems, methods, and apparatus for providing illumination using a light-turning stack having diffractive light-turning features to eject light out of the light-turning stack. In one aspect, light ejected from the light-turning stack may be applied to illuminate a display. The light-turning stack includes a light-guiding layer having a surface on which the diffractive light-turning features are disposed. A planarization layer having a refractive index different than a refractive index of the light-guiding layer directly contacts the diffractive light-turning features and has a planar surface opposite the light-turning features. The light-guiding layer can also have a planar surface opposite the light-turning features. Both these planar surfaces, on opposite sides of the light turning stack, facilitate the integration of the light-guiding layer with other layers of material, including functional layers.
