摘要:
An organic electroluminescent device cfomprising: a transparent substrate; a first electrode disposed over the substrate for injecting charge of a first polarity; a second electrode disposed over the first electrode for injecting charge of a second polarity opposite to said first polarity; an organic light-emitting layer disposed between the first and the second electrode, wherein the second electrode is reflective, the first electrode is transparent or semi-transparent, and one or more intermediate layers of dielectric material with a refractive index greater than 1.8 or a metal material is disposed between the substrate and the first electrode forming a semi-transparent mirror whereby a microcavity is provided between the reflective second electrode and the semi-transparent mirror, all the intermediate layers disposed between the substrate and the first electrode having a surface nearest the organic light-emitting layer not more than 150 nm from a surface of the first electrode nearest the organic light-emitting layer.

摘要:
Method for manufacturing an organic light emitting device or a blank for forming therefrom an organic light emitting device as well as such a OLED or blank, the organic light emitting device having a light emitting area with two opposite first sides and two opposite second sides, the method comprising at least the following steps: providing a substrate; depositing and partly removing a layer of transparent conductive material on the substrate for forming parallel anode lines which extend between the first sides; depositing and partly removing at least one conductive layer for forming contacts which are connected anode lines; wherein a photoresist layer is deposited so that it fully extends over contacts adjacent the at least one second side except for at least one contact position per cathode line, via which an electric contact between a respective cathode line to be formed and a respective contact is established.
