A head-mounted display system displays information via a matrix display element mounted within a housing that is positioned relative to at least eye of a user. 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 field of view without adjusting the supporting harness that holds the display on the user's head.

Portable communication display device

An active matrix color crystal display has an active matrix circuit, a counterelectrode panel and an interposed layer of liquid crystal. The active matrix display is located in a portable microdisplay system that has a display computer that generates images to be displayed on the liquid crystal display and connected to the active matrix liquid crystal display. A data link transmits data at a rate of speed of greater than 200 Mbytes per second in series for at least a portion between the display computer and the active matrix liquid crystal display. In a preferred embodiment, the display system has a randomizing device that alternates the amplifier through which an analog video signal passes.

Portable microdisplay system

A head mounted display system including a high resolution active matrix display which reduces center of gravity offset in a compact design. The active matrix display can be either a liquid crystal display or a light emitting display.

Head mounted display system

A camera display system displays information via a matrix display element mounted within a housing that is positioned relative to at least eye of a user. The display is connected to a video or image sensor such that the user can view information or images shown on the display. The display can be mounted to a housing so that the user can move the display in and out of the user's field of view.

Camera display system

Head-mounted display system

A display viewer has an electronic display including an array of pixel electrodes having an area of less than 400 mm . A light source can be used to illuminate the array of pixel electrodes of a liquid crystal display in a preferred embodiment. The viewer has a lens system that enlarges an image on the display and can also include a mirror that reflects the enlarged image from the lens. A display viewer in a preferred embodiment has a planar mirror and a viewing screen. The viewing screen has a diffuser and a Fresnel lens through which the image is viewed.

Microdisplay viewer

A transmissive active matrix liquid crystal display device has a multievel optical phase element that sepaeates each color component of light into a plurality of diffraction orders. The multilevel optical phase element is aligned with a an active matrix array and directs light of different colors through different pixels of a liquid crystal material. The transmission of light through the liquid crystal material is controlled by an array of transistor circuits that actuate pixel electrodes.

Active matrix liquid crystal display device

Binary optics are used in an illumination system to provide a method of imaging for a color projection display. In one embodiment a broad spectrum light source illuminates a multilevel optical phase element which disperses the broad spectrum light from the light source by diffraction. A display having a number of pixel elements, each capable of transmitting a predetermined spectral region, is positioned within the near field region of the multilevel optical phase element so as to receive the light dispersed by the multilevel phase element.

Method of imaging using a liquid crystal display device

An active matrix display panel is operated by a color sequential system to form color images. A color generator is disposed between a light source and the display panel for sequentially providing red, green and blue light. A color sequential drive circuit controls the color generator and the pixels of the display panel. The color generator is preferably a multi-stage multiple wavelength blocking filter incorporating fast switching surface stabilized liquid crystal cells.

Color sequential display panels

A head mounted display device includes a high resolution active matrix display which reduces center of gravity offset in a compact design. The display panel may be formed using a 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 then incorporated into a color display panel with a light emitting or liquid crystal material to provide the desired light valve.

Head mounted color display system

A head mounted liquid crystal display system includes a high resolution active matrix display which reduces center of gravity offset in a compact design. The display system further includes an optically transparent substrate, a circuit panel, which comprises transistors and electrodes, and a adhesive layer between the substrate and circuit panel. A driver circuit formed in the circuit panel is connected to an array of pixel circuits and drives the display system to generate images.
