  • Patent number: 8866757
    Abstract: This disclosure provides systems, methods and apparatus for a front illumination device with metalized light-turning features. In one aspect, an illumination device includes a light guide having light-turning features that include recesses formed on the light guide and that extend down into the light guide. The recesses may be coated with a material where the material also forms an auxiliary structure outside of the recesses on the light guide. The auxiliary structure may be conductive and may form, for example, an electrode.

  • Patent number: 8789996
    Abstract: 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.

  • Patent number: 8358266
    Abstract: A light guide device includes a light guide body and two or more pluralities of spaced-apart slits. The slits are formed by undercuts in the light guide body. Sidewalls of the slits form facets that redirect light impinging on the facets. In some embodiments, the light guide body is attached to a light source. The light source emits light that is injected into the light guide body and the slits redirect the light out of the light guide body and towards a desired target. In some embodiments, the target is a display and a first plurality of slits directs light from the light source across the light guide body and over the face of the display. A second plurality of slits then directs light out of the light guide body and towards the display.
