Abstract

An organic radiation-emitting component ( 1 ) comprising an organic layer ( 2 ) formed for generating radiation, and comprising a radiation coupling-out side is specified, a scattering film ( 8 ) being arranged on the radiation coupling-out side of the component and being connected to the component.

Claims (32)

1 . A component comprising:

an organic radiation-emitting element having an organic layer formed for generating radiations;

a radiation coupling-out side; and

a scattering film arranged on the radiation coupling-out side of the element and being connected to the element.

2 . The component according to claim 1 , comprising a substrate, on which the organic layer is arranged, the scattering film being arranged on that side of the substrate which is remote from the organic layer and being connected to the substrate.

3 . The component according to claim 1 , wherein,

the scattering film is formed as a transmission scattering film which scatters radiation passing through the scattering film during operation of the component.

4 . The component according to claim 1 , wherein,

the scattering film comprises a film matrix admixed with scattering particles.

5 . The component according to claim 4 , wherein scattering particles are formed such that they are radiation-transmissive.

6 . The component according to claim 4 , wherein the scattering particles comprise organic particles.

7 . The component according to claim 4 , wherein the scattering particles comprise hollow particles.

8 . The component according to claim 4 , wherein the scattering particles comprise particles with a core-shell construction.

9 . The component according to claim 4 , wherein the scattering particles have an average particle diameter of between 0.5 micrometer and 50 micrometers inclusive, preferably between 2 micrometers and 30 micrometers inclusive.

10 . The component according to claim 1 , wherein a scattering structure is formed in a surface of the scattering film.

11 . The component according to claim 10 ,

wherein the scattering film comprises a film matrix admixed with scattering particles.

12 . The component according to claim 1 , wherein the scattering film or the film matrix contains a plastic that is transmissive to the radiation generated in the component.

13 . The component according to claim 12 , wherein the plastic is a polycarbonate.

14 . The component according to claim 1 , wherein the scattering film or the film matrix is refractive-index-matched to the element.

15 . The component according to claim 13 , wherein the substrate contains glass.

16 . The component according to claim 1 , wherein the scattering film is fixed to the element by means of an adhesion promoter, or in which the scattering film is laminated onto the element.

17 . The component according to claim 1 , wherein the substrate is formed from a fragmentable material, and the scattering film is formed in mechanically stable fashion and connected to the substrate in such a way that a fragmented substrate is held together by means of the scattering film.

18 . The component according to claim 1 , wherein the scattering film has a thickness of between 1 μm and 1 mm inclusive.

19 . The component according to claim 1 , wherein an ultraviolet-radiation-absorbing element is connected to the organic radiation-emitting element.

20 . The component according to claim 19 , wherein the ultraviolet-radiation-absorbing element is arranged on that side of the substrate which is remote from the organic layer.

21 . The component according to claim 19 , wherein the element is a separate UV protective film.

22 . The component according to claim 19 , wherein the scattering film is formed such that it is UV-absorbent.

23 . The component according to claim 1 , wherein the scattering film is formed in antistatic fashion.

24 . The component according to claim 1 , wherein is formed as an organic light-emitting diode.

25 . The component according to claim 1 , wherein the element is adapted for lighting.

26 . Use of a film for a coupling-out layer for an organic radiation-emitting component.
