Abstract: A screen includes a first set of louver members at least partially disposed in the screen and located proximate to a first side of the screen, and a second set of louver members at least partially disposed in the screen and located proximate to a second side of the screen. An observer on either side of the screen sees an image produced by light directed to that observer by that set of louvers on the same side of the screen as the observer. Objects on the other side of the screen from the observer are visible to the observer between the louvers.

Abstract: In a particular embodiment, a see-through display includes a screen having transparent layer of material with a front side and a back side. At least one plurality of shaped louver members is disposed between the front side and the back side. The plurality of the louver members allow transmission of a fraction of light through the screen with minimum scattering within a range of incident angles. The plurality of the louvers also redirect image signal light from an image source into a range of angles centered about a normal to the screen. The louver members combine the image signal light with the light emitted from background objects located on the backside of the screen. The background image light is transmitted through the display screen with minimal scattering. For embodiments providing two sets of louver members, the image signal light may be redirected to observers on either side of the screen, such that the observers may see each other as well as the intended image.

Abstract: A field emission device, which among other things may be used within an ultra-high density storage system, is disclosed. The emitter device includes an emitter electrode, an extractor electrode, and a solid-state field controlled emitter that utilizes a Schottky metal-semiconductor junction or barrier. The Schottky metal-semiconductor barrier is formed on the emitter electrode and electrically couples with the extractor electrode such that when an electric potential is placed between the emitter electrode and the extractor electrode, a field emission of electrons is generated from an exposed surface of the semiconductor layer. Further, the Schottky metal may be selected from typical conducting layers such as platinum, gold, silver, or a conductive semiconductor layer that is able to provide a high electron pool at the barrier.

Abstract: In a particular embodiment, the fractional coverage louver device includes a transparent layer of material having a first surface and a second surface parallel thereto. A plurality of louver members disposed within the transparent layer of material provide fractional reflective coverage across the width of the transparent material. The louver members are aligned to receive light entering the first surface at a shallow angle relative to the first surface and direct the light out the second surface at a high angle relative to the second surface, thereby increasing the angular viewing range. Transparent areas between louver members allow a portion of incident ambient light to pass through the louver device without being reflected back to a viewer. As such, the louver device has advantageous contrast properties.

Abstract: In a particular, a high contrast projection system configured for front or rear projection includes a screen having a viewing side and a back side opposite thereto. The screen includes a transparent layer of material having louver members disposed therein to provide fractional reflective coverage across the width of the transparent material. The screen discriminates an image signal light from a source, such as a projector, from ambient light incident upon the viewing surface. The image signal light is redirected over a range of angles relative to a normal to the viewing side, while the majority of ambient light is directed generally toward the back side, for example passing through the transparent material between louver members. A light absorbing back panel adjacent to the back side absorbs the ambient light further improving contrast.
