Abstract: A head-mountable image display system provides an image to a user's eye separate from ambient light. The system includes an optical relay having an optical pathway to receive light from a display element. The optical relay also permits passage of ambient light toward the user's eye. An eyepiece assembly is disposed to redirect light on the optical pathway to the user's eye. The system is highly compact, allowing the integration of the display system with eyeglasses, a face mask, such as a diver's mask, a head set, or the like.

Abstract: The present invention relates to methods of fabricating pixel electrodes (44) for active matrix displays including the formation of arrays of transistor circuits in thin film silicon (10) on an insulating substrate and transfer of this active matrix circuit onto an optically transmissive substrate (24).

Abstract: The present invention provides a compact, remountable display device for attachment to eyewear having a head-borne frame to provide an image from an image display superposed on the ambient image. The display device includes a housing assembly which removably mounts to the head-borne frame at a location outside of a user's field of view. An electronic imaging assembly is supported by the housing assembly outside of the user's field of view and in communication with circuitry within the housing assembly to produce an image. An optical element is provided comprising a transparent fixture supporting an eyepiece assembly in front of a user's eye. The transparent fixture is located to receive the image from the electronic imaging assembly and relays the image to the eyepiece assembly, which directs the image to the user's eye.
