  • Molded frame for fixing optical elements in a liquid crystal shutter
    Patent number: 5570141
    Abstract: A molded frame for fixing optical elements in a liquid crystal shutter including a registration portion configured similar to a 35 mm slide frame for precisely registering the elements relative to one another and a mounting portion configured to mate with the outer surface of a CRT and couple the frame thereto.
    Type: Grant

  • Multiple beam laser exposure system for liquid crystal shutters
    Patent number: 5405733
    Abstract: A method for fabricating liquid crystal shutters using a laser exposure system. An output beam from the laser is split into multiple exposure beams and a photoresist coated substrate having a metallic layer is caused to traverse the beams. The substrate is then processed leaving multiple parallel electrodes on the substrate surface.

  • Optically coupled liquid crystal cell with grease
    Patent number: 5371619
    Abstract: A method for bonding together liquid crystal cells using a transparent grease. The grease maintains a level of viscosity appropriate for physically bonding the cells while matching the indices of refraction of the cells or cell layers for proper optical coupling.
