    • 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.
    • 在此描述的各种实施例中,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,以使光线返回到其原始轨迹。

    • 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.
