Abstract

An organic device is disclosed. In an embodiment the organic device includes an organic component designed to emit and/or detect radiation, wherein the organic component has a first layer stack and a radiation passage surface and an organic protection diode having a second layer stack, wherein the organic protection diode is arranged directly after the organic component in a stacking direction (Z), and wherein the organic protection diode is designed to protect the organic component from an electrostatic discharge and/or from a polarity reversal of the organic component.

Claims (41)

1. An organic device comprising:

an organic component designed to emit and/or detect radiation, wherein the organic component comprises a first layer stack and a radiation passage surface;

an organic protection diode comprising a second layer stack;

a first electrode;

a second electrode mounted on a side of the first layer stack facing away from the first electrode; and

a third electrode mounted on a side of the second layer stack facing away from the first electrode,

wherein the second electrode is in direct electrical and/or physical contact with the first layer stack and the second layer stack,

wherein the first electrode and the third electrode are connected to one another in an electrically conductive manner,

wherein the organic protection diode is arranged directly after the organic component in a stacking direction (Z), and

wherein the organic protection diode is designed to protect the organic component from an electrostatic discharge and/or from a polarity reversal of the organic component,

wherein the second layer stack comprises a layer structure, and wherein the layer structure has a thickness in the stacking direction (Z) of at least 10 μm and no more than 200 μm.

2. The organic device according to claim 1 , wherein a p-n junction of the organic protection diode is connected antiparallel to a p-n junction of the organic component.

3. The organic device according to claim 1 , wherein the first electrode and the third electrode are connected in an electrically conductive manner by a connecting layer, and wherein the connecting layer extends along the stacking direction (Z) on at least one lateral surface of the organic component and/or at least one lateral surface of the organic protection diode.

4. The organic device according to claim 1 , wherein the layer structure is arranged between the first electrode and the third electrode.

5. The organic device according to claim 1 , wherein the layer structure comprises at least one buffer layer, and wherein the buffer layer is produced by a solution-processed method.

6. The organic device according to claim 1 , wherein the layer structure comprises a buffer layer and at least one sealing layer, and wherein the sealing layer is arranged between the first layer stack and the buffer layer in the stacking direction (Z), the sealing layer and the buffer layer are produced by different methods and the buffer layer comprises at least 10 times the thickness of the sealing layer.

7. The organic device according to claim 5 , wherein the second electrode is formed using a material which is insoluble in a solvent used in the solution-processed method, and wherein the second electrode covers at least one of the lateral surfaces of the first layer stack.

8. The organic device according to claim 6 , wherein the sealing layer of the layer structure is adjacent to the second electrode and completely covers this on external surfaces of the second electrode facing away from the first layer stack in an area of the buffer layer.

9. The organic device according to claim 1 , wherein the second electrode comprises an ALD layer.

10. The organic device according to claim 1 , wherein the organic component is covered completely by at least one layer of the organic protection diode on external surfaces thereof facing away from the radiation passage surface.

11. The organic device according to claim 1 , wherein the first layer stack is covered and/or encapsulated completely by at least one layer of the organic protection diode on an external surface thereof facing away from the radiation passage surface.

12. An organic device comprising:

an organic component designed to emit and/or detect radiation, wherein the organic component comprises a first layer stack and a radiation passage surface;

an organic protection diode having a second layer stack,

wherein the organic protection diode is arranged directly after the organic component in a stacking direction (Z), and wherein the organic protection diode is designed to protect the organic component from an electrostatic discharge and/or from a polarity reversal of the organic component;

wherein the first electrode and the third electrode are connected to one another in an electrically conductive manner by a connecting layer, and wherein the connecting layer extends along the stacking direction (Z) on at least one lateral surface of the organic component and/or at least one lateral surface of the organic protection diode.

13. An organic device comprising:

an organic component designed to emit and/or detect radiation, wherein the organic component comprises a first layer stack and a radiation passage surface;

an organic protection diode comprising a second layer stack;

a first electrode;

a second electrode mounted on a side of the first layer stack facing away from the first electrode; and

a third electrode mounted on a side of the second layer stack facing away from the first electrode,
