Jan Blochwitz-Niemoth 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).

  • Light emitting component comprising organic layers
    Patent number: 7074500
    Abstract: The invention relates to a light-emmiting component having organic layers, in particular to an organic light-emmiting diode. The component has at least one doped charge carrier transport layer (2), a light-emmiting layer (4) and contact layers (1, 5) and also has a blocking layer (3; 3?) wherein an organic material is provided between the charge carrier transport layer (2, 2?) and the light-emmiting layer (4). The energy levels of the charge carried transport layer are chosen in such a way that efficient doping is possible and the blocking layer nevertheless ensures that non-radiating recombination processes on the interface with the emitting layer are prevented.

    Abstract: The invention relates to a light-emmiting component having organic layers, in particular to an organic light-emmiting diode. The component has at least one doped charge carrier transport layer (2), a light-emmiting layer (4) and contact layers (1, 5) and also has a blocking layer (3; 3′) wherein an organic material is provided between the charge carrier transport layer (2, 2′) and the light-emmiting layer (4). The energy levels of the charge carried transport layer are chosen in such a way that efficient doping is possible and the blocking layer nevertheless ensures that non-radiating recombination processes on the interface with the emitting layer are prevented.
