    摘要: This disclosure provides systems, methods and apparatus for providing illumination by using a light guide to distribute light and for determining spacing between light turning features in the light guide. In one aspect, a light intensity profile along a first axis is determined and the pitch of light turning features along that first axis is varied based upon this profile, while the pitch along a second crossing axis (for example, an orthogonal axis) and the sizes of the light turning features remain unchanged. In some implementations, an apparatus includes a light guide having an array of light turning features configured to turn light from at least one light emitter. The light turning features can be non-uniformly spaced apart along a first axis such that pitches vary non-monotonically and, along a second axis that crosses the first axis, the light turning features are spaced apart with substantially the same progression.

    摘要: An integrated illumination apparatus includes a light injection portion having a first end for receiving light from a light source. The light injection portion includes material that supports propagation of said light along the length of the light injection portion. Turning microstructure is disposed on a first side of the light injection. The turning microstructure is configured to turn at least a substantial portion of light incident on the first side and to direct the portion of the light out a second opposite side of the light injection portion. A slit is disposed along the length of the light injection portion. The slit forms an optical interface on the second opposite side of the light injection portion that provides total internal reflection for light propagating along the length of the light injection portion to be guided therein. The optical interface further transmits light turned by said turning microstructure. A light distribution portion is disposed with respect to the slit to receive the light turned by said turning microstructure and transmitted out of the second side of the light injection portion and through said slit. At least one bridge is disposed between light injection portion and the light distribution portion. The bridge mechanically connects the light injection portion to the light distribution portion.

    摘要: This disclosure provides systems, methods and apparatus for providing illumination by using a light guide to distribute light. In one aspect, a passivation layer is attached to the light guide of an illumination device. The passivation layer may be an optically transparent moisture barrier and may have a thickness and refractive index which allows it to function as an anti-reflective coating. The passivation layer may protect moisture-sensitive underlying features, such as metallized light turning features that may be present in the light guide. The light turning features may be configured to redirect light out of the light guide. In some implementations, the redirected light may be applied to illuminate a display.

    摘要: Various embodiments of the present invention relate to enhancing the brightness of displays that employ illumination systems. In some embodiments, the illumination systems include light guides, diffractive microstructure, and light-turning features. The diffractive microstructure may be configured to receive ambient light at a first angle and produce diffracted light at a second angle greater than the first angle and greater than the critical angle for of light guide. The light is thereby guided within the light guide. The light-turning features may be configured to turn the light guided within the light guide out of a light guide and onto, for example, a spatial light modulator at near normal incidence.

    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.
