1 zeigt eine kurze technische Erläuterung des Prinzips einer in einer OLED-Anzeigevorrichtung verwendeten OLED 1. Eine OLED ist eine Leuchtdiode aus organischen, halbleitenden Verbindungen, wie beispielsweise Polymeren oder kleinen Molekülen, die bei einer elektrischen Anregung Licht emittieren. Bei den für OLEDs typischen Schichtdicken sind sie transparent. Die Polymere werden in einer oder mehreren Schichten zwischen einer Anode 2 und einer Kathode 3, wie in 1 aufgetragen, wo hier zwei Schichten dargestellt sind, nämlich eine leitende Polymerschicht 4 und eine darüber liegende lichtemittierende Polymerschicht 5. Die Schichtdicke liegt im Bereich weniger 100 nm. Anode 2 und Kathode 3 bestehen ebenfalls aus einem transparenten Material, beispielsweise unter Verwendung von Indium-Zinn-Oxid. Die OLED 1 wird auf einem transparenten Substrat 6, vorzugsweise einem Glassubstrat oder Folie oder ähnliches aufgebracht und anschließend mit einem transparenten Deckel 7, ebenfalls aus Glas oder Folie, luftdicht verschlossen. Die aus einer Vielzahl von OLEDs zusammengefügte OLED-Anzeige hat einen großen Blickwinkelbereich von bis zu 170° und eine hohe Schaltgeschwindigkeit. Die Transmission beträgt im ausgeschalteten Zustand bis zu 85%. 1 shows a brief technical explanation of the principle of an OLED used in an OLED display device 1 , An OLED is a light-emitting diode made of organic semiconducting compounds, such as polymers or small molecules that emit light upon electrical excitation. At the layer thicknesses typical for OLEDs, they are transparent. The polymers are in one or more layers between an anode 2 and a cathode 3 , as in 1 plotted, where here two layers are shown, namely a conductive polymer layer 4 and an overlying light emitting polymer layer 5 , The layer thickness is in the range of less than 100 nm. Anode 2 and cathode 3 are also made of a transparent material, for example using indium tin oxide. The OLED 1 is on a transparent substrate 6 , preferably a glass substrate or foil or the like applied and then with a transparent lid 7 , also made of glass or foil, hermetically sealed. The OLED display, assembled from a large number of OLEDs, has a wide viewing angle range of up to 170 ° and a high switching speed. The transmission is up to 85% when switched off.
