  • Patent number: 6800498
    Abstract: A method of producing an organic light-emitting device comprising a patterned electroluminescent polymer layer arranged between two electrodes such that charge carriers can move between the first and second electrodes an the electroluminescent polymer layer, the method comprising the steps of (a) providing a substrate comprising the first electrode, (b) depositing solid particles comprising the electroluminescent polymer onto selected portions of the surface of the substrate, and (c) securing to the substrate those solid particles comprising electroluminescent polymer particles deposited onto the substrate in step (b) to form the patterned electroluminescent polymer; and (d) forming the second electrode over the surface of the electroluminescent.

  • Patent number: 6558219
    Abstract: A method of forming an electroluminescent device, including the steps of forming a first charge carrier injecting layer for injecting charge carriers of a first polarity, forming an organic charge carrier transport layer over the first charge carrier injecting layer, the transport layer having an electronic and/or optical property which varies across the thickness of the transport layer, forming an organic light emissive layer over the transport layer, and forming a second charge carrier injecting layer over the light emissive layer for injecting charge carriers of a second polarity.
