Robert Tress 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).

  • Organic light emitting diode, method for producing an organic light emitting diode and module comprising at least two organic light emitting diodes
    Patent number: 9105863
    Abstract: An organic light emitting diode includes a substrate and an organic layer sequence, which generates electromagnetic radiation during operation. The organic layer sequence is arranged in a central region of the substrate A metallization is arranged in an edge region of the substrate and is designed for making electrical contact with the organic layer sequence. A separately produced metallic contact structure is cohesively and electrically conductively connected to the metallization by a joining process based on ultrasonic technology.
