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.

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.
