Abstract

A packaging method and a display device are disclosed. The packaging method includes: packaging a display element on a substrate having the display element disposed thereon to form a package covering the display element, wherein a first substance is disposed on at least a part of the substrate inside the package, the first substance including thermite; and initiating the first substance to obtain a second substance including a product of the thermite reaction.

First claim

What is claimed is:

1. A display device comprising:
a substrate;
a display element, disposed on the substrate;
a package covering the display element; and
a substance disposed on at least a part of the substrate inside the package, the substance comprising a product of thermite reaction,
wherein the package is in a lid shape and is in direct contact with the substrate to form a contact area, and the substance is disposed in a gap between the contact area and the display element.

2. The display device of claim 1 , wherein the substance is disposed in an area where the substrate contacts the package.

3. The display device of claim 1 , wherein the substance is disposed between a joining edge between the substrate and the package and an edge of the display element.

4. The display device of claim 1 , wherein the substance is separated from the display element.

5. The display device of claim 1 , wherein the substance further comprises inorganic oxides, inorganic nitrides or a mixture of both.

6. A display device comprising:
a substrate;
a display element, disposed on the substrate;
a package in a shape of a lid, covering the display element; and
a first substance, disposed on at least a part of the substrate inside the package, the first substance comprising thermite;
wherein the first substance is configured to be initiated to start a thermite reaction so as to obtain a second substance comprising a product of the thermite reaction,
wherein the package is in direct contact with the substrate to form a contact area, and the first substance is disposed in a gap between the contact area and the display element.

7. The display device of claim 6 , wherein the first substance is separated from the display element.

8. The display device of claim 6 , wherein the first substance is disposed between a joining edge between the substrate and the package and an edge of the display element.

9. The display device of claim 6 , wherein the first substance is disposed in an area where the substrate contacts the package.

10. The display device of claim 6 , wherein a part of the first substance extends to the exterior of the package and becomes exposed.

11. The display device of claim 6 , wherein the first substance is included in a glue.

12. The display device of claim 6 , wherein the first substance further comprises inorganic oxides, inorganic nitrides or a mixture of both.

13. The display device of claim 6 , wherein the second substance is disposed in an area where the substrate contacts the package.

14. The display device of claim 6 , wherein the second substance is disposed between a joining edge between the substrate and the package and an edge of the display element.

15. The display device of claim 6 , wherein the second substance is separated from the display element.

16. The display device of claim 6 , wherein the second substance further comprises inorganic oxides, inorganic nitrides or a mixture of both.

17. The display device of claim 6 , wherein the package is in direct contact with the substrate to form a contact area, and the second substance is disposed in a gap between the contact area and the display element.
