Patents by Inventor Richard Lunt

Richard Lunt 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).

  • Patent number: 11374172
    Abstract: Methods and systems for organic vapor jet deposition are provided, where an exhaust is disposed between adjacent nozzles. The exhaust may reduce pressure buildup in the nozzles and between the nozzles and the substrate, leading to improved deposition profiles, resolution, and improved nozzle-to-nozzle uniformity. The exhaust may be in fluid communication with an ambient vacuum, or may be directly connected to a vacuum source.
    Type: Grant
    Filed: December 21, 2010
    Date of Patent: June 28, 2022

  • Patent number: 9054335
    Abstract: A first device is provided. The first device includes an organic light emitting device, which further comprises a first electrode, a second electrode, and an organic emissive layer disposed between the first and second electrode. Preferably, the second electrode is more transparent than the first electrode. The organic emissive layer has a first portion shaped to form an indentation in the direction of the first electrode, and a second portion shaped to form a protrusion in the direction of the second electrode. The first device may include a plurality of organic light emitting devices. The indentation may have a shape that is formed from a partial sphere, a partial cylinder, a pyramid, or a pyramid with a mesa, among others. The protrusions may be formed between adjoining indentations or between an indentation and a surface parallel to the substrate.

  • Patent number: 8017863
    Abstract: A photoactive device includes a photoactive region disposed between and electrically connected to two electrodes where the photoactive region includes a first organic photoactive layer comprising a first donor material and a second organic photoactive layer comprising a first acceptor material. The first donor material contains photoactive polymer-wrapped carbon nanotubes and the photoactive region includes one or more additional organic photoactive material layers disposed between the first donor material layer and the acceptor material layer. The photoactive region creates excitons upon absorption of light in the range of about 400 nm to 1450 nm.

  • Patent number: 7879401
    Abstract: Methods and systems for organic vapor jet deposition are provided, where an exhaust is disposed between adjacent nozzles. One or more carrier gases may be provided and ejected from a plurality of nozzles. An exhaust may be provided to create a localized vacuum between nozzles. The exhaust may reduce pressure buildup in the nozzles and between the nozzles and the substrate, leading to improved deposition profiles, resolution, and improved nozzle-to-nozzle uniformity. The exhaust may be in fluid communication with an ambient vacuum, or may be directly connected to a vacuum source.
