Abstract: An electronic device includes a substrate having a primary surface, an array lying along the primary surface, wherein the array includes one or more radiation-emitting components, one or more radiation-responsive components, or any combination thereof, and a first edge connector. In a direction parallel to the primary surface, the first edge connector lies between the array and a perimeter of the substrate. In one embodiment, the electronic device is designed, such that during normal operation, the first edge connector has a temperature difference, due to current flow through the first edge connector, of no more than 10° C. In another embodiment, the array has an emission homogeneity of at least 75% over a lifetime of the electronic device. The electronic device can be operated with good emission intensity and have an extended electronic device lifetime compared to an electronic device having edge connectors that can cause local heating.

Abstract: A process for protecting first electrodes, conductive leads and the underlying substrate from the process of removing organic layers during the fabrication of an organic electronic device. After first electrodes and conductive leads are formed over a substrate, a protective layer is selectively formed over the structure, with the protective layer not being disposed over selected portions of the first electrodes, the conductive leads and the substrate. Organic layers are then formed over the structure, and second electrodes are formed over the organic layers. Those portions of the organic layers disposed over the selected portions of the first electrodes, conductive leads and substrate are removed, and the protective layer protects adjacent portions of the first electrodes, conductive leads and substrate from the process of removing the portions of the organic layers.

Abstract: The energy levels (HOMO, LUMO) of the conjugated polymer are tuned independently, so that an energy match on both sides of the device can be accomplished while keeping the emission color in the blue region. Such polymers can be formed by polymerization of a mixture of monomers. The mixture of the monomers contains at least one monomer having an electron-deficient group sandwiched by two aromatic hydrocarbon groups (“Monomer (I)”) and at least one hole transporting (“HT”) monomer. The mixture of monomers may also contain a solubility enhancement (“SE”) monomer and/or a Branching Monomer. Such polymers can be used in fabricating light emitting diodes to achieve some of the best device performance to date including high efficiency and blue color purity.
