Abstract

The invention relates to a flexible organic light-emitting diode. The diode includes at least one curved part, of which at least one portion is covered with a layer of varnish.

First claim

The invention claimed is:

1. Flexible organic light-emitting diode, wherein the diode comprises at least one curved part, of which at least one portion is covered with a layer of varnish.

2. Flexible organic light-emitting diode according to claim 1 , wherein the thickness of the layer of varnish covering the portion is variable as a function of the radius of curvature of the curved part.

3. Flexible organic light-emitting diode according to claim 1 , wherein the thickness of the layer of varnish is less than or equal to the thickness of the flexible organic light-emitting diode.

4. Flexible organic light-emitting diode according to claim 1 , wherein the at least one portion covered with a layer of varnish is a portion that emits light.

5. Flexible organic light-emitting diode according to claim 1 , wherein the varnish is transparent or translucent.

6. Flexible organic light-emitting diode according to claim 1 , wherein the at least one portion covered with a layer of varnish is a portion that does not emit light.

7. Flexible organic light-emitting diode according to claim 1 , wherein the diode is in the form of a sheet comprising an emitting face and a non-emitting face.

8. Flexible organic light-emitting diode according to claim 7 , wherein the portion covered with a layer of varnish is a portion of the non-emitting face.

9. Luminous module comprising at least one curved flexible organic light-emitting diode according to claim 8 .

10. Method for shaping a flexible organic light-emitting diode, comprising a first step consisting in providing a flexible organic light-emitting diode, a second processing step comprising at least one step of applying a varnish to at least one portion of the flexible organic light-emitting diode, and a third stiffening step consisting in stiffening the varnish in order to keep the flexible organic light-emitting diode in a predetermined shape.

11. Shaping method according to claim 10 , wherein a flexible organic light-emitting diode is provided according to a first shape in the first step, and in that the third stiffening step consists in keeping the flexible organic light-emitting diode in a predetermined second shape which is different to the first shape.

12. Shaping method according to either claim 10 , wherein the second processing step furthermore comprises a step of shaping the flexible organic light-emitting diode according to the predetermined second shape.

13. Shaping method according to claim 12 , wherein the shaping step is carried out before the step of applying the varnish.

14. Shaping method according to claim 12 , wherein the shaping step is carried out after the step of applying the varnish.

15. Shaping method according to claim 10 , wherein the step of applying the varnish is a step of spraying the varnish onto said at least portion of the flexible organic light-emitting diode.

16. Flexible organic light-emitting diode according to claim 2 , wherein the thickness of the layer of varnish is less than or equal to the thickness of the flexible organic light-emitting diode.

17. Flexible organic light-emitting diode according to claim 2 , wherein the at least one portion covered with a layer of varnish is a portion that emits light.

18. Flexible organic light-emitting diode according to claim 2 , wherein the varnish is transparent or translucent.

19. Flexible organic light-emitting diode according to claim 2 , wherein the at least one portion covered with a layer of varnish is a portion that does not emit light.

20. Flexible organic light-emitting diode according to claim 2 , wherein the diode is in the form of a sheet comprising an emitting face and a non-emitting face.
