Abstract

A display device using semiconductor light emitting element, and including a display module including semiconductor light emitting element; a frame on which a plurality of the display modules is arranged; a first connection member which fixes the display module onto the frame on a rear surface of the display module, and which provides planar fluidity; and a second connection member having a magnet provided on a side surface of the display module, and applying attractive force to adjacent the display module.

Claims (45)

1 . A display device using a semiconductor light emitting element, the display device comprising:

a display module including the semiconductor light emitting element;

a frame in which a plurality of the display modules is arranged;

a first connection member configured to fix the display module onto the frame at a rear surface of the display module, and provide planar fluidity; and

a second connection member configured to include a magnet provided on a side surface of the display module, and provide attractive force to adjacent the display module,

wherein the first connection member includes:

an accommodation portion provided in the frame; and

an insertion portion provided on a rear surface of the display module, inserted into the accommodation portion to fix the display module, and having a smaller width than the accommodation portion, and

wherein the insertion portion includes:

a first structure connected to the rear surface of the display module; and

a second structure connected vertically to an end of the first structure, and including a protrusion provided on an inner surface thereof facing the rear surface of the display module.

2 . The display device according to claim 1 , wherein:

in a state where the insertion portion is inserted into the accommodation portion, the second structure elastically supports the protrusion toward the rear surface of the frame.

3 . The display device according to claim 1 , wherein:

the protrusion is continuously formed from an end of the inner surface of the second structure to a portion connected to the first structure; and

at least one protrusion is provided on the inner surface of the second structure.

4 . The display device according to claim 1 , wherein the second connection member includes:

a first magnet provided on a side surface of the display module; and

a second magnet provided on a side surface of another display module facing the side surface of the display module, and

wherein the first magnet and the second magnet are formed at positions facing each other.

5 . The display device according to claim 4 , wherein:

at least one second connection member is provided on each side surface of the display module.

6 . The display device according to claim 5 , wherein the second connection member includes:

a magnet having polarity opposite to that of a magnet included in another second connection member adjacent to the second connection member.

7 . The display device according to claim 4 , wherein:

any one of the first magnet and the second magnet includes a magnetic material.

8 . The display device according to claim 1 , wherein:

the frame includes:

a first connector arranged in an upward direction; and

a first connector guide configured to fix the first connector to the frame,

the display module includes:

a second connector arranged in a downward direction so as to be electrically connected to the first connector; and

a second connector guide configured to fix the second connector to the display module.

9 . The display device according to claim 8 , wherein:

at least one of the first connector guide and the second connector guide is elastically supported in an upward or downward direction.

10 . The display device according to claim 8 , wherein:

the first connector guide includes:

at least one guide protrusion formed to protrude upward from a portion that is in contact with the second connector guide, and

the second connector guide includes:

at least one guide hole formed to accommodate the guide protrusion therein.

11 . The display device according to claim 8 , wherein the frame further includes:

a module control circuit electrically connected to the first connector to control the plurality of the display modules.

12 . The display device according to claim 1 , further comprising:

a side case formed to cover a side surface of the display device,

wherein the side case is coupled to the second connection member of the display module by magnetic attraction.
