Abstract

A display device is provided. The display device includes a housing, a display panel provided inside the housing, a cover layer coupled to an upper side of the display panel and including a protruding area that protrudes beyond a side surface of the display panel, an inner mold disposed on a lower side of the protruding area of the cover layer so as to be spaced a predetermined distance from the side surface of the display panel, and a sealing member provided in a spacing S between the inner mold and the display panel, wherein the sealing member contacts each of the display panel, the cover layer, and the inner mold.

First claim

What is claimed is:

1 . A display device, comprising:
a housing; a display panel provided inside the housing; a cover layer coupled to an upper side of the display panel and comprising a protruding area that protrudes beyond a side surface of the display panel; an inner mold disposed on a lower side of the protruding area of the cover layer so as to be spaced a predetermined distance from the side surface of the display panel; and a sealing member provided in a spacing S between the inner mold and the display panel, wherein the sealing member contacts each of the display panel, the cover layer, and the inner mold.

2 . The display device of claim 1 ,
wherein the housing comprises a first groove provided on the inside, and wherein the inner mold comprises a first insertion area inserted into the first groove.

3 . The display device of claim 1 ,
wherein the inner mold comprises a second groove provided on a surface of the inner mold facing the housing, and wherein the housing comprises a second insertion area inserted into the second groove.

4 . The display device of claim 1 , wherein the inner mold comprises:
a first surface facing the protruding area of the cover layer; a second surface opposite the first surface and facing the housing; a third surface extending from the first surface to the second surface and facing the sealing member; and a fourth surface extending from the first surface to the second surface and opposite the third surface.

5 . The display device of claim 4 , wherein the inner mold is a columnar cross-section extending from the first surface toward the second surface.

6 . The display device of claim 4 , wherein the second surface of the inner mold is disposed to protrude beyond a bottom surface of the display panel.

7 . The display device of claim 1 , wherein the display device further comprises:
a first adhesive member that adheres the housing to the inner mold, and is made of a thermoplastic material.

8 . The display device of claim 7 , wherein the display device further comprises:
a second adhesive member that adheres the cover layer to the inner mold, and is made of a different material from the first adhesive member.

9 . The display device of claim 1 , wherein the inner mold is disposed to protrude a predetermined distance from a side surface of the cover layer.

10 . The display device of claim 1 , wherein the housing is spaced a predetermined distance from the side surface of the cover layer such that a gap G is formed between the housing and the cover layer.

11 . The display device of claim 1 , wherein the inner mold comprises a guide area protruding from an upper side surface of the inner mold facing a side surface of the cover layer.

12 . The display device of claim 11 , wherein the guide area provides a buffer to the cover layer such that the cover layer is not disposed in close contact with the housing.

13 . A manufacturing method of a display device, comprising:
coupling, a cover layer comprising a protruding area that protrudes beyond a side surface of a display panel, to an upper side of the display panel; coupling an inner mold to a lower side of the protruding area so as to be spaced a predetermined distance from the side surface of the display panel; filling a sealing member into a spacing S between the inner mold and the display panel; and coupling the inner mold to a housing such that the display panel is disposed inside the housing, wherein the filling of the sealing member comprises:
filling the sealing member such that the sealing member contacts each of the display panel, the cover layer, and the inner mold.

14 . The manufacturing method of claim 13 , wherein the coupling of the inner mold to the housing comprises:
inserting a first insertion area of the inner mold into a first groove provided on the inside of the housing.

15 . The manufacturing method of claim 13 , wherein the coupling of the inner mold to the housing comprises:
inserting a second insertion area of the housing into a second groove provided in the inner mold.

16 . The manufacturing method of claim 13 , wherein the coupling of the inner mold to the lower side of the protruding area comprises:
coupling the inner mold to the protruding area such that the inner mold protrudes a predetermined distance from a side surface of the cover layer.

17 . The manufacturing method of claim 13 , wherein the coupling of the inner mold to the housing comprises:
placing the housing at a predetermined distance spaced from the side surface of the cover layer such that a gap G is formed between the housing and the cover layer.

18 . The manufacturing method of claim 13 , wherein the coupling of the inner mold to the housing comprises:
applying a first adhesive member made of a thermoplastic material to an area where the housing and the inner mold come into contact.

19 . The manufacturing method of claim 18 , wherein the coupling of the inner mold to the lower side of the protruding area comprises:
applying a second adhesive member made of a different material from the first adhesive member to an area where the protruding area and the inner mold come into contact.

20 . A disassembling method of a display device by separating a display module from a housing that accommodates the display module, the display module including a display panel, a cover layer coupled to an upper side of the display panel and comprising a protruding area that protrudes beyond a side surface of the display panel, an inner mold disposed on a lower side of the protruding area of the cover layer so as to be spaced a predetermined distance from the side surface of the display panel, and a sealing member provided in a spacing S between the inner mold and the display panel and contacting each of the display panel, the cover layer, and the inner mold, the disassembling method comprising:
heating a first adhesive member made of a thermoplastic material and provided between the inner mold and the housing, and separating the display module from the housing, and wherein the heating of the first adhesive member comprises: in a lower direction of the housing, heating an external area of the housing opposite a position where the inner mold is disposed.

21 . The disassembling method of claim 20 , wherein the separating of the display module from the housing comprises:
separating a first insertion area of the inner mold from a first groove provided in the housing.

22 . The disassembling method of claim 20 , wherein the separating of the display module from the housing comprises:
separating a second insertion area of the housing from a second groove provided in the inner mold.
