Abstract

The present invention relates to a display device. A display device according to an embodiment of the present invention may comprise: a display module; a support frame disposed at the rear of the display module; and a hinge module hingedly connecting the display module to the support frame. The hinge module may comprise: a first fastening part fastened to the display module; a first body part connected to the first fastening part and protruding further rearward than the first fastening part; an insertion part protruding downward from the first body part; a second fastening part fastened to the support frame; a second body part connected to the second fastening part and protruding forward from the second fastening part; a first insertion groove recessed downward from the upper surface of the second body part and into which the insertion part is rotatably fitted; a second insertion groove which is in communication with the first insertion groove and is located on a side of the first insertion groove, and into which the insertion part is rotatably fitted.

First claim

What is claimed is:

1 . A display device comprising:
a display module; a support frame disposed behind the display module; and a hinge module configured to hinge-connect the display module to the support frame, wherein the hinge module comprises:
a first fastening part fastened to the display module;
a first body part connected to the first fastening part and protruding backward from the first fastening part;
an insertion part protruding downward from the first body part;
a second fastening part fastened to the support frame;
a second body part connected to the second fastening part and protruding forward from the second fastening part;
a first insertion groove which is recessed downward from a top surface of the second body part and into which the insertion part is rotatably inserted; and
a second insertion groove which is configured to communicate with the first insertion groove and disposed at a side of the first insertion groove and into which the insertion part is rotatably inserted.

2 . The display device according to claim 1 , wherein the hinge module comprises:
a first through-hole configured to vertically pass through the first body part and the insertion part; a second through-hole configured to pass downward from an inner bottom surface of the second insertion groove; and a hinge pin inserted into the first through-hole and the second through-hole.

3 . The display device according to claim 1 , wherein the insertion part has a first width in one direction and a second width greater than the first width in the other direction crossing the one direction.

4 . The display device according to claim 3 , wherein the first insertion groove has an inner diameter greater than an inner diameter of the second insertion groove, and
a portion at which the first insertion groove and the second insertion groove communicate with each other has a width less than the inner diameter of the second insertion groove.

5 . The display device according to claim 4 , wherein the portion at which the first insertion groove and the second insertion groove communicate with each other has a width greater than the first width and less than the second width.

6 . The display device according to claim 1 , further comprising:
a magnet provided on a front surface of the support frame; and a magnetic body provided on a rear surface of the display module to apply attractive force by the magnet.

7 . The display device according to claim 6 , wherein the hinge module is connected to an edge of one side of the rear surface of the display module, and
the magnetic body is provided on an edge of the other side of the rear surface of the display module.

8 . The display device according to claim 1 , wherein the display module comprises:
a display panel; a back plate disposed behind the display panel; a magnet plate disposed between the display panel and the back plate; and a plurality of reinforcing frames fastened to a rear surface of the back plate, wherein at least a portion of the plurality of reinforcing frames is in contact with the support frame.

9 . The display device according to claim 8 , wherein an upper end of the display panel is higher than an upper end of the back plate.

10 . The display device according to claim 9 , wherein a lower end of the display panel is disposed at the same height as a lower end of the back plate.

11 . The display device according to claim 8 , wherein the display panel comprises:
a display area on which an image or picture is displayed; a first non-display area disposed above the display area; and a second non-display area disposed under the display area, wherein a vertical width of the first non-display area is less than a vertical width of the second non-display area.

12 . The display device according to claim 11 , wherein a distance between an upper end of the display panel and an upper end of the back plate is the same as the vertical width of the second non-display area.

13 . A display device comprising:
a first display module; a second display module disposed under the first display module; a support frame disposed behind the first display module and the second display module; and a hinge module configured to hinge-connect each of the first display module and the second display module to the support frame, wherein the hinge module comprises:
a first fastening part fastened to the first display module or the second display module;
a first body part connected to the first fastening part and protruding backward from the first fastening part;
an insertion part protruding downward from the first body part;
a second fastening part fastened to the support frame;
a second body part connected to the second fastening part and protruding forward from the second fastening part;
a first insertion groove which is recessed downward from a top surface of the second body part and into which the insertion part is rotatably inserted; and
a second insertion groove which is configured to communicate with the first insertion groove and disposed at a side of the first insertion groove and into which the insertion part is rotatably inserted.

14 . The display device according to claim 13 , wherein the first display module comprises:
an upper display panel; and an upper back plate which is disposed behind the upper display panel and to which the hinge module is connected, wherein the second display module comprises: a lower display panel; and a lower back plate which is disposed behind the lower display panel and to which the hinge module is connected.

15 . The display device according to claim 14 , wherein a portion of a lower side of the lower display panel is configured to cover a portion of an upper side of the upper display panel at a front side.

16 . The display device according to claim 14 , wherein at least one of the first display panel or the second display panel is elastically deformed.

17 . The display device according to claim 14 , wherein each of the upper display panel and the lower display panel comprises:
a display area on which an image or picture is displayed; a first non-display area disposed above the display area; and a second non-display area disposed under the display area, wherein a vertical width of the first non-display area is less than a vertical width of the second non-display area.

18 . The display device according to claim 17 , wherein the first non-display area of the lower display panel is disposed in front of the second non-display area of the upper display panel.
