  • Patent number: 6963081
    Abstract: In an embodiment of the invention, an electronic device includes an interfacial layer with traps. This interfacial layer is between an electrode and an organic layer, and if the electrode was adjacent to the organic layer, the energy barrier between these two layers is such that the current through the organic layer is limited by charge injection into this layer rather than the transport properties of the organic layer. The traps are used to accumulate charges of one charge type (e.g., either electrons or holes) within the interfacial layer. By accumulating charges, the bands of the interfacial layer are bent so that charges can tunnel from the electrode to the organic layer thus increasing the efficiency of the electronic device and allowing organic layers to be used within an electronic device that otherwise would be too inefficient for use in that device.

  • Patent number: 6911667
    Abstract: An embodiment of the present invention pertains to encapsulating an organic electronic device by selectively depositing a catalyst layer and then exposing the catalyst layer to a monomer to produce a planarization layer. The monomer reacts only in the areas where the catalyst layer is present so there is minimal or no contamination of other areas of the organic electronic device. Selectively depositing the catalyst layer allows the resulting planarization layer to be patterned. A barrier layer is selectively deposited on at least the planarization layer. Another embodiment of the present invention pertains to encapsulating an organic electronic device by depositing a planarization layer on a transfer substrate and then allowing it to stabilize to minimize its reactivity. The planarization layer is transferred from the transfer substrate onto at least an active area of the organic electronic device. A barrier layer is selectively deposited on at least the planarization layer.
