Abstract

An organic light-emitting component is disclosed. The component includes an organic functional layer stack between two electrodes, where the organic functional layer stack has at least two organic light-emitting layers and at least one charge generation layer, and where at least one of the at least two organic light-emitting layers is part of the charge generation layer.

Claims (13)

1. An organic light-emitting component comprising:

an organic functional layer stack between two electrodes, wherein one of the two electrodes is transparent;

wherein the organic functional layer stack comprises at least two organic light-emitting layers and at least one charge generation layer; and

wherein at least one of the at least two organic light-emitting layers is part of the charge generation layer; and

wherein the at least one of the at least two organic light-emitting layers that is part of the charge generation layer comprises an emitter material.

2. The organic light-emitting component of claim 1 , wherein the other one of the two electrodes is non-transparent and reflective.

3. The organic light-emitting component of claim 1 , wherein at least one of the electrodes comprises at least one of the following materials: Ag, Pt, Au, Mg, or Ag:Mg.

4. The organic light-emitting component of claim 1 , wherein the charge generation layer comprises an electron-conducting layer.

5. The organic light-emitting component of claim 1 , wherein the charge generation layer comprises a hole-conducting layer.

6. The organic light-emitting component of claim 1 , wherein an undoped intermediate layer is arranged between an electron-conducting layer and a hole-conducting layer of the charge generation layer.

7. The organic light-emitting component of claim 6 , wherein the intermediate layer comprises a metal or a metal oxide.

8. The organic light-emitting component of claim 1 , wherein the emitter material simultaneously acts as a dopant.

9. The organic light-emitting component of claim 1 , wherein the at least one of the at least two organic light-emitting layers that is part of the charge generation layer additionally comprises a dopant.
