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： This disclosure provides systems, methods and apparatus for providing illumination by using a light guide to distribute light. In one aspect, the light guide includes a light turning film over an optically transmissive supporting layer. The light turning film may be formed of a material deposited in the liquid state. The light turning film may be formed of a photodefinable material, which may be glass, such a spin-on glass, or may be a polymer. In some other implementations, the glass is not photodefinable. The light turning film may have indentations that define light turning features and a protective layer may be formed over those indentations. The protective layer may also be formed of a glass material, such as spin-on glass. The light turning features in the light guide film may be configured to redirect light out of the light guide, for example, 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： A front light guide panel including a plurality of embedded surface features is provided. The front light panel is configured to deliver uniform illumination from an artificial light source disposed at one side of the font light panel to an array of display elements located behind the front light guide while allowing for the option of illumination from ambient lighting transmitted through the light guide panel. The surface embedded surface relief features create air pockets within the light guide panel. Light incident on the side surface of the light guide propagates though the light guide until it strikes an air/light material guide interface at one on the air pockets. The light is then turned by total internal reflection through a large angle such that it exits an output face disposed in front of the array of display elements.
