  • Color sequential display panels
    Patent number: 5642129
    Abstract: A color active matrix display system allows random access of pixel electrodes. The control electronics is fabricated with the active matrix circuitry using single crystal silicon technology. The control electronics includes a random access data scanner and random access spec scanners.

  • Method of making an eye tracking system having an active matrix display
    Patent number: 5583335
    Abstract: An eye tracking system is disclosed which is comprised of an eye tracking module formed of a display joined to a photodetector array.

  • Reduction of parasitic effects in floating body mosfets
    Patent number: 5578865
    Abstract: A semiconductor fabrication method improves the voltage characteristic of floating-body MOSFETs by creating recombination centers near the source-body junction of the device. A MOSFET is fabricated through the passivation oxidation stage, and a photolithography step is used to expose the source region. Implantation is then performed using one of two types of material. A first type creates electron traps of predetermined energy in the vicinity of the source-body junction. A second type creates defects in the crystalline structure of the semiconductor material. Both implantation types create recombination centers in the material. This allows the discharge through the source-body junction of charges built up in the body region.

  • Compact high resolution light valve projector
    Patent number: 5550604
    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.

  • Method for mounting light valves for projection display system
    Patent number: 5455678
    Abstract: Liquid crystal display panels are mounted to a beam combining prism such that each display panel can flex in the place of the display panel as a result of thermal stresses. Mirrors having a cover glass plate substantially equivalent to the cover glass on the display panels are used to establish the image planes. A three-point clip mount for each display panel is then positioned based on the respective image plane. The mirrors are then replaced with the actual display panels and the optical system is then finely adjusted. After the fine adjustments, the mounting clips are bonded to the display panels.
