摘要： An illumination apparatus includes a light bar, a plurality of indentations in the light bar on a first side of the light bar, and a contoured reflective surface including a plurality of protruding surface portions, such that the surface portions reflect light transmitted through sloping sidewalls of the indentations. 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. The protrusions on the contoured reflective surface and the indentations on the light bar can have complimentary shapes and/or aligned in certain embodiments.

摘要： In various embodiments described herein, a front light guide panel comprises a plurality surface relief features having a variety of different sloping surface portions. Light injected into an edge of the light guide propagates though the light guide until it strikes one of the surface relief features. The light is then turned by total internal reflection such that the light is directed onto a reflective modulator array rearward of the light guide panel. The light reflects from the modulator array and is transmitted back through the surface features of the light guide panel. 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 having equal and opposite surface relief features is disposed forward of the light guide panel. Light reflected from the modulator array and passing through surface relief features on the light guide panel is refracted a second time by the conjugate film to return the rays to their original trajectory.
摘要翻译： 在本文所述的各种实施例中，前导光板包括具有各种不同倾斜表面部分的多个表面浮雕特征。 注入光导的边缘的光通过光导传播，直到其撞击到其中一个表面浮雕特征。 然后光被全内反射转动，使得光被引导到导光板后面的反射调制器阵列上。 光从调制器阵列反射并通过导光板的表面特征被透射回来。 然而，根据光入射在表面特征上的位置，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源于不同的位置，并且出现了幽灵图像。 为了减少这种重影，具有相同和相对的表面浮雕特征的共轭膜设置在导光板的前方。 从调制器阵列反射并穿过导光板上的表面浮雕特征的光被共轭膜第二次折射，以将光线返回到其原始轨迹。

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.
