摘要： An illumination device includes a holographic film 89 and a light source 93, such as a point light source. The point light source 93 is positioned at an edge of the holographic film and has a light emitting face that faces the edge of the holographic film 89. The holographic film 89 includes a hologram formed of diffractive refractive index structures. The density of the diffractive refractive index structur-es increases with increasing distance from the light source 93. Light is propagated from the light source 93 through the holographic film 89, such as by total internal reflection. The diffractive refractive index structures turn the light, thereby causing the light to propagate out of the holographic film 89 in a desired direction. In some embodiments, the light propagating out of the holographic film 89 has a high uniformity across the surface of the holographic film 89.

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： An optical isolation structure is incorporated into a display between the display elements and the transparent substrate for the display elements. The optical isolation structure reflects light rays within the substrate that impact the structure at high angles relative to normal to the structure, thereby permitting the substrate to be used as an integrated light guide for distributing light over the display from a light source on the edge of the substrate. The optical isolation structure may include a single layer having an index of refraction less than the substrate or a plurality of thin-film interference layers.

摘要： A reflective or transmissive hologram may be used to extract light from a waveguide. The hologram may be formed by separately exposing each of a plurality of areas of a holographic medium with object beams and/or reference beams having attributes (e.g., illumination angles) that vary randomly or pseudorandomly over the entire hologram. The areas may be contiguous (e.g., in a tiled pattern) or overlapping. In some embodiments, the spacing and/or orientation of the diffraction gratings may vary from area to area. For example, the spacing and/or orientation of the diffraction gratings may vary randomly or pseudorandomly from area to area. Some parts of the hologram may intentionally be made relatively more or relatively less efficient at extracting light from the waveguide.

摘要： In various embodiments described herein, a front light guide panel (80) comprises a plurality surface relief features (89) having a variety of different sloping surface portions (89a, 89b). Light (170) injected into an edge of the light guide (80) propagates though the light guide (80) until it strikes one of the surface relief features (89). The light is then turned by total internal reflection such that the light is directed onto a reflective modulator array (81) rearward of the light guide panel (80). The light reflects from the modulator array (81) and is transmitted back through the surface features (89) of the light guide panel (80). However, depending upon where the light is incident on the surface features, the light will be refracted at different angles by the different sloping surface portions. As a result, light reflected from a single point on the modulator array appears to originate from different locations, and ghost images appear. To reduce such ghosting, a conjugate film (92) having equal and opposite surface relief features (99) is disposed forward of the light guide panel (80). Light reflected from the modulator array (81) and passing through surface relief features (89) on the light guide panel is refracted a second time by the conjugate film (92) to return the rays to their original trajectory.
摘要翻译：在本文所述的各种实施例中，前部光导面板（80）包括具有各种不同倾斜表面部分（89a，89b）的多个表面起伏特征（89）。注入到光导（80）边缘的光（170）传播通过光导（80），直到它撞击表面起伏特征（89）中的一个。然后通过全内反射使光转向，使得光被引导到导光板（80）后面的反射调制器阵列（81）上。光从调制器阵列（81）反射并且通过导光板（80）的表面特征（89）被传回。然而，根据光入射到表面特征上的位置，光将被不同的倾斜表面部分以不同的角度折射。结果，从调制器阵列上的单个点反射的光似乎来自不同的位置，并且出现重影图像。为了减少这种重影，具有相等和相反的表面起伏特征（99）的共轭膜（92）设置在导光板（80）的前方。从调制器阵列（81）反射并且穿过导光板上的表面起伏特征（89）的光被共轭膜（92）第二次折射以使射线返回到它们的原始轨迹。

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.
