Abstract

A packaging method and a display device are disclosed. The packaging method comprises: 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 comprising thermite; and initiating the first substance to obtain a second substance comprising a product of the thermite reaction.

First claim

What is claimed is:

1. A packaging method, comprising:
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 comprising thermite; and
initiating the first substance to obtain a second substance comprising a product of the thermite reaction,
wherein the package has a lid shape and 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.

2. The method of claim 1 , wherein the first substance is separated from the display element.

3. The method of claim 2 , wherein the first substance is disposed between a joining edge between the substrate and the package and an edge of the display element.

4. The method of claim 2 , wherein the first substance is disposed in an area where the substrate contacts the package.

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

6. The method of claim 1 , wherein the first substance is disposed in an area where the substrate contacts the package.

7. The method of claim 1 , wherein the first substance is included in a glue.

8. The method of claim 1 , wherein before packaging the display element, the method further comprises:
applying the first substance to the substrate around the display element.

9. The method of claim 1 , wherein before packaging the display element, the method further comprises:
applying the first substance to a side of the package that faces the display element.

10. The method of claim 9 , wherein the method further comprises attaching the package with the first substance applied thereto to the display element.

11. The method of claim 1 , wherein a width of the first substance is 0.5 mm.

12. The method of claim 1 , wherein the first substance further comprises inorganic oxides, inorganic nitrides or a mixture of both.

13. The method of claim 1 , wherein initiating the first substance comprises:
initiating the thermite to start the thermite reaction via ignition or thermal effect.

14. The method of claim 1 , wherein a part of the first substance extends to the exterior of the package and becomes exposed.
