| 20100053771 | FLAT PANEL LENS - A flat panel lens system as a tapered light guide that has minimal or no margin for fan out. The tapered light guide includes a thin end, and a thick end of which is a bevelled mirror or an optical equivalent. Light is injected into the thin end and the mirror is such that rays injected through a point at the thin end emerge collimated from one of the light guide surfaces, and that collimated rays injected at an appropriate angle through one of the light guide surfaces emerge from a point at the thin end. Bragg gratings can be utilized for color implementations as well. The tapered light guide can be fabricated as a single piece, by extrusion, injection molding, or the combination/variation of extrusion and injection molding, as well as other commonly known techniques. | 03-04-2010 |
| 20100177387 | END REFLECTOR FOR A FLAT PANEL LENS - End reflectors, flat panel lens that may utilize the end reflector, and methods are provided. The end reflector for a flat panel lens may include a first grating having a first set of parallel planes. The first set of parallel planes may be of layers of alternating refractive indexes disposed at a first angle with a central plane of the flat panel lens. The end reflector may also include a second grating having a second set of parallel planes. The second set of parallel planes may be of layers of alternating refractive indexes of alternating refractive indexes disposed at a second angle with the central plane. The second angle may be equivalent to the first angle reflected about the central plane. | 07-15-2010 |
| 20100231498 | IMAGE DISPLAY VIA MULTIPLE LIGHT GUIDE SECTIONS - Various embodiments related to a multi-section light guide and computing devices comprising a plurality of wedge light guides are disclosed. For example, one disclosed embodiment comprises a multi-section light guide having a monolithic wedge-shaped body comprising a plurality of logical light guide sections. Each logical light guides section is configured to direct light via total internal reflection between a first light input/output interface located at a first end of the logical light guide section and a second light input/output interface located at a major face of the logical light guide section. | 09-16-2010 |
| 20100300608 | MAKING AN OPTIC WITH A CLADDING - Embodiments related to making an optic comprising a cladding are disclosed. One example embodiment comprises forming a wedge-shaped light guide having opposing first and second faces and comprising a material having a first refractive index. The embodiment further comprises applying a cladding layer to the first face, and, applying an interface layer to the cladding layer. In this embodiment, the cladding layer has a second refractive index less than the first refractive index, and the interface layer has a third refractive index matched to the first refractive index. | 12-02-2010 |
