Abstract
Official abstract text for this publication.
An organic light-emitting component includes a substrate on which a functional layer stack is applied, the stack including a first electrode, an organic functional layer stack thereover including an organic light-emitting layer and a translucent second electrode thereover, and a translucent halogen-containing thin-film encapsulation arrangement over the translucent second electrode, wherein a translucent protective layer having a refractive index of more than 1.6 is arranged directly on a translucent second electrode between the translucent second electrode and the thin-film encapsulation arrangement, and the thin-film encapsulation arrangement is arranged directly on the translucent protective layer.

Opening claim text (preview).
The invention claimed is: 1. An organic light-emitting component comprising a substrate on which a functional layer stack is applied, the stack comprising a first electrode, an organic functional layer stack thereover comprising an organic light-emitting layer and a translucent second electrode thereover, and a translucent halogen-containing thin-film encapsulation arrangement over the translucent second electrode, wherein a translucent protective layer having a refractive index of more than 1.6 is arranged directly on a translucent second electrode between the translucent second electrode and the thin-film encapsulation arrangement, and the thin-film encapsulation arrangement is arranged directly on the translucent protective layer. 2. The component according to claim 1 , wherein the protective layer has a refractive index of more than 1.8. 3. The component according to claim 1 , wherein the protective layer has a refractive index of more than 2.0. 4. The component according to claim 1 , wherein the protective layer comprises one or more selected from the group consisting of zirconium dioxide, titanium dioxide, zinc oxide, hafnium dioxide, tin dioxide, tantalum oxide and vanadium oxide. 5. The component according to claim 1 , wherein the protective layer is halogen-free. 6. The component according to claim 1 , wherein the substrate and the first electrode are translucent. 7. The component according to claim 1 , wherein the protective layer is formed as layer stack with at least two layers, each of said layers being halogen-free. 8. An organic light-emitting component comprising a substrate on which a functional layer stack is applied, the stack comprising a first electrode, an organic functional layer stack thereover comprising an organic light-emitting layer and a translucent second electrode thereover, and a translucent halogen-containing thin-film encapsulation arrangement over the translucent second electrode, wherein a translucent protective layer having a refractive index of more than 1.6 is arranged directly on a translucent second electrode between the translucent second electrode and the thin-film encapsulation arrangement, and the protective layer consists of vanadium oxide. 9. An organic light-emitting component comprising a substrate on which a functional layer stack is applied, the stack comprising a first electrode, an organic functional layer stack thereover comprising an organic light-emitting layer and a translucent second electrode thereover, and a translucent halogen-containing thin-film encapsulation arrangement over the translucent second electrode, wherein a translucent protective layer having a refractive index of more than 1.6 is directly arranged on a translucent second electrode between the translucent second electrode and the thin-film encapsulation arrangement, the thin-film encapsulation arrangement is arranged directly on the translucent protective layer, and the translucent protective layer consists of vanadium oxide.
