摘要： Various embodiments of the invention include an interferometric optical modulator comprising a substrate layer and a light direction layer. Such an interferometric modulator may be integrated with a diffuser layer in a display device in a way that physically integrates the diffuser layer into the light direction layer in a way where the diff-user layer does not interact with light propagating within the light direction layer. As a result, most of the light propagating within the light direction layer does not penetrate into the diffuser which would inhibit performance of the display. In some embodiments, the interface between the diffuser layer and the light direction layer has a lower index of refraction than the light direction layer and the transparent substrate so that total internal reflection occurs at the interface.

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。

In one embodiment, the display element includes a first layer that is at least partially transmissive of light, a second layer that is at least partially reflective of light, and a photovoltaic element that is formed on the first layer or the second layer or formed between the first layer and the second layer. The second layer is spaced from the first layer and is selectably movable between a first position in which the display element has a first reflectivity and a second position in which the display element has a second reflectivity. The first reflectivity is greater than the second reflectivity. The photovoltaic element is at least partially absorptive of light and is configured to convert a portion of the absorbed light into electric energy, at least when the second layer is in the second position.
