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： 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，前导光板（80）包括具有各种不同倾斜表面部分（89a，89b）的多个表面浮雕特征（89）。注入光导（80）的边缘的光（170）通过光导（80）传播，直到其撞击到一个表面浮雕特征（89）。然后光被全内反射转动，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）反射并通过导光板（80）的表面特征（89）传输回来。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（99）的共轭膜（92）被布置在导光板（80）的前方。从调制器阵列（81）反射并穿过导光板上的表面浮雕特征（89）的光被共轭膜（92）第二次折射，以将光线返回到其原始轨迹。
