Abstract: A monocular head mounted display system in which a matrix display element is mounted within a housing that is positioned relative to one eye of the user to display information. The display is connected to a video or information source such that the user can view information or images shown on the display. The display can be mounted to a frame so that the user can move the display in and out of the user's filed of view without adjusting the supporting harness that holds the display on the user's head.

Abstract: The present invention relates to a light valve projector in which a small high resolution active matrix transmission display is used with a light source, coupling optics and a projection lens to provide a compact presentation system. A preferred embodiment of the system comprises a three light valve system with an arc lamp within a compact housing in which dichroic mirrors separate light from the source into three primary colors and directs the separated light through three active matrix displays manufactured by a thin film transfer process and having a small active area.

Abstract: A passive matrix display device obtains fast response times and high resolutions by fabricating the control circuitry and passive matrix electrodes together as a single monolithic device. The electrodes and the control circuitry are fabricated as an SOI structure on a substrate. The structure is removed from the substrate and transferred to a glass substrate using a lift-off and transfer process. Performance is further increased by incorporating an active addressing procedure instead of standard multiplex addressing.

Abstract: A display panel is formed using essentially single crystal thin-film material that is transferred to substrates for display fabrication. Pixel arrays form light valves or switches that can be fabricated with control electronics in the thin-film material prior to transfer. The resulting circuit panel is than incorporated into a display panel with a light emitting or liquid crystal material to provide the desired display.

Abstract: A method of producing sheets of crystalline material is disclosed, as well as devices employing such sheets. In the method, a growth mask is formed upon a substrate and crystalline material is grown at areas of the substrate exposed through the mask and laterally over the surface of the mask to form a sheet of crystalline material. This sheet is optionally separated so that the substrate can be reused. The method has particular importance in forming sheets of crystalline semiconductor material for use in solid state devices.

Abstract: Light emitting diodes (LEDs) and LED bars and LED arrays formed of semiconductive material, such as III-V, and particularly AlGaAs/GaAs material, are formed in very thin structures using organometallic vapor deposition (OMCVD). Semiconductor p-n junctions are formed as deposited using carbon as the p-type impurity dopant. Various lift-off methods are described which permit back side processing when the growth substrate is removed and also enable device registration for LED bars and arrays to be maintained.
