Title (EN) ORGANIC LIGHT-EMITTING DIODE (LED) AND METHOD FOR THE PRODUCTION THEREOF
(FR) DIODE ELECTROLUMINESCENTE ORGANIQUE ET SON PROCEDE DE PRODUCTION
(DE) ORGANISCHE LEUCHTDIODE (LED) UND VERFAHREN ZU IHRER HERSTELLUNG
Abstract:
(EN) An organic layer (1) is applied to a transparent carrier (2) in such a way that several partial segments with different refractive indices are configured in the layer. Fewer photons remain trapped in the layer as a result of waveguide losses than in homogenous layers due to diversion at the phase limits within the layer.
(FR) Selon l'invention, une couche organique (1) est déposée sur un support transparent (2) de façon à réaliser dans la couche différentes zones partielles ayant des indices de réfraction différents. Grâce à la déviation au niveau des limites de phase à l'intérieur de la couche, moins de photons restent prisonniers dans la couche en raison de pertes de guidage d'ondes que dans des couches homogènes.
(DE) Eine organische Schicht (1) wird derart auf einen transparenten Träger (2) aufgebracht, dass in der Schicht verschiedene Teilbereiche mit unterschiedlichen Brechungsindices ausgebildet werden. Wegen der Umlenkung an den Phasengrenzen innerhalb der Schicht bleiben weniger Photonen durch Wellenleitverluste in der Schicht gefangen als bei homogenen Schichten.
