Abstract

The present disclosure relates to the field of display technology, and discloses a package structure and an organic light emitting display apparatus. The package structure includes a self-repairing functional layer and a heating layer for heating the self-repairing functional layer. A forming material of the self-repairing functional layer at least includes: a self-repairing material.

Claims (35)

1. A package structure, for packaging a display apparatus, the package structure comprising:

an inorganic layer;

a self-repairing functional layer attached to the inorganic layer; and

a heating layer formed on the self-repairing function layer for heating the self-repairing functional layer,

wherein the self-repairing functional layer comprises at least a self-repairing material to repair a crack in the inorganic layer,

wherein the self-repairing functional layer comprises: an organic layer, and the self-repairing material is doped within the organic layer, and

wherein a temperature of a self-repairing reaction of the self-repairing material is lower than a glass transition temperature of a forming material of the organic layer.

2. The package structure of claim 1 , wherein a doping mass ratio of the self-repairing material in the organic layer is less than or equal to 30%.

3. The package structure of claim 1 , wherein the inorganic layer comprises a first inorganic layer and a second inorganic layer, wherein the self-repairing functional layer is located between the first inorganic layer and the second inorganic layer.

4. The package structure of claim 3 , wherein the heating layer is located on a side of the first inorganic layer away from the second inorganic layer.

5. The package structure of claim 3 , wherein the heating layer is located on a side of the second inorganic layer away from the first inorganic layer.

6. The package structure of claim 3 , wherein the heating layer is located on a side of the self-repairing functional layer towards the first inorganic layer.

7. The package structure of claim 3 , wherein the heating layer is located on a side of the self-repairing functional layer towards the second inorganic layer.

8. The package structure of claim 1 , wherein the self-repairing material comprises: at least one of ethylene-vinyl acetate copolymer, polyethylene oxide, polyolefin elastomer (POE), polydimethylsiloxane, and polyethylene glycol.

9. The package structure of claim 1 , wherein a thickness of the self-repairing functional layer is greater than or equal to 2 microns and less than or equal to 8 microns.

10. The package structure of claim 1 , wherein the heating layer is a graphene layer or a metal mesh layer or a metal thin film layer.

11. An organic light emitting display apparatus, comprising an organic light emitting device, and the package structure located on the organic light emitting device as claimed in claim 1 .

12. The organic light emitting display apparatus of claim 11 , wherein a resistance of the heating layer is greater than that of the organic light emitting device.

13. The organic light emitting display apparatus of claim 11 , wherein the heating layer is connected to an external circuit through an array layer within the organic light emitting device.

14. A package structure, for packaging a display apparatus, the package structure comprising:

an inorganic layer;

a self-repairing functional layer attached to the inorganic layer; and

a heating layer formed on the self-repairing function layer for heating the self-repairing functional layer,

wherein the inorganic layer comprises a first inorganic layer and a second inorganic layer, wherein the self-repairing functional layer is located between the first inorganic layer and the second inorganic layer, and

wherein the heating layer is located between the first inorganic layer and the self-repairing functional layer.

15. A package structure, for packaging a display apparatus, the package structure comprising:

an inorganic layer;

a self-repairing functional layer attached to the inorganic layer; and

a heating layer formed on the self-repairing function layer for heating the self-repairing functional layer,

wherein the self-repairing functional layer comprises at least a self-repairing material to repair a crack in the inorganic layer,

wherein the self-repairing functional layer comprises: an organic layer, and the self-repairing material is doped within the organic layer,

wherein the inorganic layer comprises a first inorganic layer and a second inorganic layer, wherein the self-repairing functional layer is located between the first inorganic layer and the second inorganic layer, and
