Abstract

The invention concerns a light-emitting component with an arrangement of electrodes for applying an electrical voltage to multiple organic areas, which form a light-emitting area, are distributed across a component surface and which each emit light when the electrical voltage is applied, in which the multiple organic areas are arranged between a flat-formed electrode and a flat-formed counter-electrode, where the electrode consists of a part electrode and an additional part electrode, which is electrically isolated from the part electrode and is formed so that it interlocks with it, where the electrode and the counter-electrode are formed so that they do not overlap outside the light-emitting area when looking towards the component surface.

Claims

1. Light-emitting component with an electrode arrangement for the application of an electrical voltage to multiple organic areas, which form a light-emitting area and are distributed across a component surface and which each emit light when the electric current is applied, in which the multiple organic areas are arranged between a flat-formed electrode and a flat-formed counter-electrode, where the electrode consists of a part electrode and an additional part electrodes, which is electrically isolated from the part electrode and formed to interlock with it, where the electrode, and counter-electrode are formed so that they do not overlap each other outside the light-emitting area when looking towards the component surface.

2. Light-emitting component according to claim 1, wherein the counter-electrode has a part counter-electrode and an additional part counter-electrode, which is electrically isolated from the part counter-electrode and interlocks with it, and that the part electrode and the additional part electrode, and the part counter-electrode and the additional part counter-electrode, are arranged opposite each other when looking towards the component surface.

3. Light-emitting component according to claim 1, wherein the part electrode and the additional part electrode are each in contact with two different organic areas out of the multiple organic areas.

4. Light-emitting component according to claim 3, wherein the two different organic areas are formed so that they emit light of different colors.

5. Light-emitting component according to claim 1, wherein the part electrode and the additional part counter-electrode are formed so that they overlap, at least partially, within the light-emitting area when looking towards the component surface.

6. Light-emitting component according to claim 1, wherein the additional part-electrode and the part counter-electrode are each in contact with precisely one of the organic areas.

7. Light-emitting component according to claim 3, wherein the precisely one organic area emits light, which differs from the light, which is omitted by the two different organic areas.

8. Light-emitting component according to claim 1, wherein the electrode electrode sections of the part electrode and electrode sections of the additional part electrode are arranged offset to one another having a gap in between when looking towards the component surface.

9. Light-emitting component according to claim 2, wherein the counter-electrode, electrode sections of the part counter-electrode and electrode sections of the additional part counter-electrode are arranged offset to one another having a gap in between when looking towards the component surface.

10. Light-emitting component according to claim 1, wherein the electrode and/or the counter-electrode has strip-formed electrode sections.

11. Light-emitting component according to claim 1, wherein the electrode and/or the counter-electrode are each formed in a single layer.

12. Light-emitting component according to claim 1, wherein the electrode and/or the counter-electrode are distributed across multiple layers.

13. Light-emitting component according to claim 1, wherein the electrode and/or the counter-electrode within the light-emitting area are formed to substantially overlap the organic areas completely within the light-emitting area.

14. Light-emitting component according to claim 1, wherein the part electrode and the additional part electrode, and the part counter-electrode and the additional part counter-electrode interlock with each other in the form of a comb.

15. Light-emitting component according to claim 1, wherein the multiple organic areas have an aggregate white light emission spectrum.

16. Light-emitting component with an electrode arrangement for applying an electrical voltage to multiple organic areas, which are arranged between a flat-formed electrode and a flat-formed counter-electrode of the electrode arrangement and emit light when the electrical voltage is applied, where an arrangement of multiple series circuits is formed, in which:

the electrode is formed as multiple strip segments arranged adjacent to each other, and the counter-electrode is segmented;

the multiple organic areas are each connected to multiple strip segments of the electrodes; and

by the segmented counter-electrodes, each of the organic areas is connected to one adjacent strip segment, which is arranged adjacent to one of the multiple strip segments, so that one part of the multiple organic areas is connected to one adjacent strip segment on one side and another part of the organic areas is connected to an adjacent strip segment on an opposite side.
