Optoelectronic component and method for producing an optoelectronic component
View Patent ↗An optoelectronic component may include: at least one layer of the optoelectronic component; at least one adhesive on the layer of the optoelectronic component; and a cover on the at least one adhesive; wherein the at least one adhesive is cured only in a partial region above at least one of a substrate and the layer.
1. An optoelectronic component, comprising:
at least one layer of the optoelectronic component;
at least one adhesive on the layer of the optoelectronic component; and
a cover on the at least one adhesive;
wherein the at least one adhesive is cured only in a partial region above at least one of a substrate and the layer; and
wherein, after being cured, the partial region at least partly encloses a region in which a liquid adhesive is provided, wherein the liquid adhesive is configured to flow into a defect location.
2. The optoelectronic component as claimed in claim 1 ,
wherein the partial region comprises the edge region of the at least one adhesive.
3. The optoelectronic component as claimed in claim 2 ,
wherein the edge region is at least one part of a circumferential structure of the at least one adhesive.
4. The optoelectronic component as claimed in claim 1 ,
wherein the partial region is arranged at least partly laterally outside an active region of the optoelectronic component.
5. The optoelectronic component as claimed in claim 1 ,
wherein the at least one adhesive comprises a plurality of adhesives of differing viscosity.
6. The optoelectronic component as claimed in claim 1 ,
wherein particles are provided in the adhesive, said particles having a different refractive index than the adhesive.
7. The optoelectronic component as claimed in claim 1 ,
wherein the adhesive has a lower refractive index than the cover.
8. The optoelectronic component as claimed in claim 1 ,
wherein an optically refractive layer is provided on at least one surface of the cover.
9. The optoelectronic component as claimed in claim 1 , designed as a light emitting diode.
10. The optoelectronic component as claimed in claim 1 , designed as an organic light emitting diode.
11. The optoelectronic component as claimed in claim 1 ,
wherein the layer comprises an encapsulation layer of the optoelectronic component.
12. The optoelectronic component as claimed in claim 1 ,
wherein the cover comprises glass.
13. The optoelectronic component as claimed in claim 1 ,
wherein the cover comprises a film.
14. The optoelectronic component as claimed in claim 1 ,
wherein the partial region at least partly encloses a region in which a liquid non-adhesive material is provided.
15. An optoelectronic component, comprising:
at least one layer of the optoelectronic component;
at least one adhesive on the layer of the optoelectronic component; and
a cover on the at least one adhesive;
wherein the at least one adhesive is cured only in a partial region above at least one of a substrate and the layer; and
wherein the partial region at least partly encloses a region in which a liquid non-adhesive material is provided.
16. The optoelectronic component as claimed in claim 15 ,
wherein the at least one adhesive is cured in a partial region that at least partially encloses a region comprising the at least one adhesive in a liquid, uncured form.
17. The optoelectronic component as claimed in claim 15 ,
wherein particles are provided in the at least one adhesive, said particles having a different refractive index than the at least one adhesive.
18. A method for producing an optoelectronic component,
wherein the method comprises:
applying a cover to a layer of the optoelectronic component by means of at least one adhesive; and
varying the viscosity of the at least one adhesive only in a partial region above a substrate of the optoelectronic component and above the layer;
wherein, after varying the viscosity, the partial region at least partly encloses a region in which a liquid adhesive remains, wherein the liquid adhesive is configured to flow into a defect location.
19. The method as claimed in claim 18 ,
wherein the viscosity is varied by means of light irradiation.
20. The method as claimed in claim 19 ,
wherein the light irradiation is effected by means of irradiation by ultraviolet light.
