Abstract

A display device includes a display module, a first case and a boss insertion element having a combination hole. The first case covers a first surface of the display module and has a first boss which is inserted into the combination hole to combine the front case to the display module. The first boss is formed at inside edges of the display module.

Claims

1. A display device comprising:

a display module including a boss insertion element having a combination hole and a first receiving frame contacting a lower surface of a mold frame of the display module to support the mold frame, the boss insertion element having a portion perpendicularly extending between the mold frame and the first receiving frame to contact the lower surface of the mold frame and an upper surface of the first receiving frame; and

a first case, the first case covers a first surface of the display module and has a first boss disposed in the combination hole to combine the front case to the display module, wherein the first boss is disposed at inside edges of the display module.

2. The display device of claim 1, wherein the mold frame and the first receiving frame each comprise a hole for exposing the combination hole to the outside of the display module.

3. The display device of claim 2, wherein the mold frame further comprises a recess for receiving the boss insertion element.

4. The display device of claim 2, wherein the boss insertion element comprises a supporting plate which contacts the first receiving frame.

5. The display device of claim 4, wherein the boss insertion element has a protruding portion protruded from the supporting plate and inserted into said hole of the first receiving frame.

6. The display device of claim 4, wherein the boss insertion element further comprises a fixing plate formed thereon being opposite to the supporting plate.

7. The display device of claim 6, wherein the supporting plate and the fixing plate contact the mold frame alternatively being opposite to each other.

8. The display device of claim 6, wherein the supporting plate and the fixing plate are protruded from a main body defining the boss insertion element disposed in the combination hole.

9. The display device of claim 1, wherein the first boss formed on the first case corresponds to a corner of the display module.

10. The display device of claim 1, wherein the boss insertion element includes an elastic material.

11. The display device of claim 10, wherein the boss insertion element includes rubber.

12. The display device of claim 1, further comprising a second case covering a second surface of the display module, which is opposite to the first surface of the display module, the second case having a second boss formed to correspond to a location of the first boss and is inserted into the combination hole of the boss insertion element.

13. The display device of claim 12, wherein the combination hole is formed to correspond to cross-sectional shapes of the first and second bosses.

14. The display device of claim 12, wherein each of the first and second bosses comprises a conical shape, and the combination hole comprises a circular shape.

15. The display device of claim 12, wherein the first and second bosses are combined with each other in the combination hole.

16. The display device of claim 1, wherein the boss insertion element includes a protrusion portion formed on an inside surface of the combination hole.

17. The display device of claim 1, further comprising a second receiving frame coupled to the first receiving frame.

18. A method for fabricating a display device, the method comprising:

inserting a body of a boss insertion element into a hole formed on a mold frame such that a fixing plate extending laterally from the body of the boss contacts an upper surface of the mold frame, the body of the boss insertion element defining a combination hole, the boss insertion element having a portion perpendicularly extending laterally from the body to contact a lower surface of the mold frame;

putting the mold frame in a first receiving frame so that the portion of the boss insertion element contacts an upper surface of the first receiving frame; and

inserting a boss protruding from a first case covering a first surface of a display module into the combination hole.

19. The method for fabricating a display device according to claim 18, wherein of the inserting the body of the boss insertion element into the hole formed on the mold frame comprises:

inserting the boss insertion element into the hole formed on the mold frame until the fixing plate having a larger cross section than the area of the hole passes through said hole.

20. A method for fabricating a display device comprising:

inserting a boss insertion element including a combination hole and a fixing plate into a hole formed on a mold frame until the fixing plate contacts an outer portion of the mold frame;

rotating the boss insertion element to a predetermined angle to fix the boss insertion element to the mold frame;

disposing the mold frame in a first receiving frame; and

inserting a boss protruded from a first case covering a first surface of a display module into the combination hole.
