    摘要: This disclosure provides systems, methods and apparatus for providing illumination by using a light guide to distribute light. In one aspect, the light guide has a surface, such as an edge, into which light is injected. The surface is treated to create a diffusive interface with a light source. For example, the surface may be subjected to abrasion to form a frosted surface that acts as the diffusive interface, or a diffusive structure may be attached to the edge, with the attached diffusive structure functioning as the diffusive interface. The diffusive interface diffuses light entering into the light guide, and can thereby increase the uniformity of light propagating within the light guide. The light guide may be provided with light turning features that redirect light out of the light guide. In some implementations, the redirected light may be applied to illuminate a display.

    摘要: In various embodiments described herein, a display device includes a front illumination apparatus that comprises a first light guide disposed forward of an array of display elements, such as an array of interferometric modulators, to distribute light across the array of display elements. The light guide panel is edge illuminated by a light source positioned behind the array display elements. The light from such a light source is coupled to a second light guide disposed behind the array of display elements and positioned laterally with respect to the light source. The light in the second light guide is coupled into the first light guide using a small optical coupling element such as a turning mirror. In some embodiments the second light guide may comprise the backplate of the display device.
