J. Lodewyk Steyn 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).

  • MEMS anchor and spacer structure
    Patent number: 9213181
    Abstract: A display apparatus includes a first substrate, a plurality of microelectromechanical systems (MEMS) light modulators formed from a structural material coupled to the first substrate and a second substrate separated from the first substrate. A plurality of spacers extend from the first substrate to keep the second substrate a minimum distance away from the plurality of light modulators. The spacers include a first polymer layer having a surface in contact with the first substrate, a second polymer layer encapsulating the first polymer layer and a layer of the structural material encapsulating the second polymer layer. The spacers can be used as fluid barriers and configured to surround more than one but less than all of the MEMS light modulators in the display apparatus.
