Patents by Inventor Tobias W. Walker

Tobias W. Walker has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Wafer scale processing
    Patent number: 6890786
    Abstract: This invention relates to a method of fabricating a light modulation system having a semiconductor substrate. In one exemplary method, an optical layer is applied over a semiconductor substrate which includes a plurality of integrated circuits. Each of these integrated circuits is capable of creating a separate display device. A protective layer is then applied over the optical layer. The plurality of integrated circuits is then singulated. Various other embodiments of apparatuses and methods are disclosed.
    Type: Grant
    Filed: April 22, 2002
    Date of Patent: May 10, 2005
    Assignee: Brillian Corporation
    Inventors: Tobias W. Walker, Douglas J. McKnight, Kam Wan
  • Micro liquid crystal displays
    Patent number: 6825909
    Abstract: The invention relates to liquid crystal displays and method of making liquid crystal displays. One liquid crystal display invention has as an element an optically transmissive first substrate that may be positioned to receive light incident from the light source. A reflective second substrate is positioned adjacent to this first substrate. The second substrate has an active area that may include a circuit panel and a perimeter seal area surrounding that active area. To separate the first substrate from the second substrate, spacers are configured about the perimeter seal area of the second substrate. Between the first substrate and the second substrate is a liquid crystal material. Other embodiments are disclosed.
