    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： Broad band white color can be achieved in MEMS display devices by incorporating a material having an extinction coefficient (k) below a threshold value for wavelength of light within an operative optical range of the interf erometric modulator. One embodiment provides a method of making the MEMS display device comprising depositing said material (23) over at least a portion of a transparent substrate (20), depositing a dielectric layer (24) over the layer of material, forming a sacrificial layer over the dielectric, depositing an electrically conductive layer (14) on the sacrificial layer, and forming a cavity (19) by removing at least a portion of the sacrificial layer. The suitable material may comprise germanium, germanium alloy of various compositions, doped germanium or doped germanium -containing alloys, and may be deposited over the transparent substrate, incorporated within the transparent substrate or the dielectric layer.

    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.

    摘要： Various embodiments of a display device described herein include an optical propagation region (97), at least one optical loss structure (93), an optical isolation layer (95), and a plurality of display elements (91). The propagation region includes a light guide in which light is guided via total internal reflection and turning features configured to redirect the light out of the propagation region. The loss structure would disrupt the total internal reflection of at least some of the light guided within the propagation region if disposed directly adjacent thereto. The optical isolation layer includes a non-gaseous material between the propagation region and the loss structure, and is configured to increase an amount of light that is totally internal reflected in the propagation region. The plurality of display elements are positioned to receive the light redirected out of the propagation region. The loss structure is positioned between the plurality of display elements and the propagation region.
