    摘要: 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.

    摘要: Disclosed are apparatus and methods for illuminating a display. In certain embodiments, the illumination apparatus includes a light guide that receives light from a light generator along an edge of the light guide and directs the received light via light extractor features (e.g., grooves) towards a display. The light guide includes at least two sets of light extractor features that are rotated with respect to each other so as to reduce a shadowing effect on the display when the display is viewed from within a specific range of viewing angles. In further embodiments, the spacing or orientation of each or one of the extractor feature sets may also be adjusted so that other visual artifacts, such as a Moiré effect, are reduced.
