Abstract

A multi-display device according to an embodiment of the present disclosure includes: a frame; a plurality of display modules fixed to the front of the frame; and an adjuster provided between each of the plurality of display modules and the frame, and installed such that the height of the display modules is adjustable at the rear of the frame.

First claim

The invention claimed is:

1. A multi-display device comprising:
a frame;
a plurality of display modules fixed to a front surface of the frame; and
an adjuster provided between each of the plurality of display modules and the frame, and installed so that a height of the display modules is adjustable at a rear of the frame,
wherein the adjuster includes:
a pillar portion formed to protrude toward the frame on a rear surface of a display module of the plurality of display modules, the pillar portion having a screw line therein, and having a recess formed on an outer peripheral surface of the pillar portion, and the recess being formed on a surface of the pillar portion facing the frame, and
a rubber-made elastic member fitted into the recess of the pillar portion, and protruding out of the pillar portion,

wherein the display module is fixed to the frame while the height is adjusted by a bolt fastened to the pillar portion on a rear surface of the frame,
wherein the elastic member is in direct contact with the recess and the frame, and
wherein the surface of the pillar portion facing the frame is apart from the frame.

2. The multi-display device of claim 1 , wherein a height of the elastic member is larger than a height of the pillar portion, and
wherein the elastic member protrudes outside of the pillar portion.

3. The multi-display device of claim 1 , wherein the frame further includes a supporter supporting a rear circumference of each of the plurality of display modules on the front surface of the frame.

4. The multi-display device of claim 3 , wherein the adjuster is arranged immediately neighboring to the supporter.

5. The multi-display device of claim 4 , wherein the adjuster includes at least two first adjusters arranged respectively at corners of the display module and a second adjuster arranged between the at least two first adjusters.

6. The multi-display device of claim 1 , wherein a height adjustment range of the display module is 0 to 0.5 millimeters (mm).

7. The multi-display device of claim 1 , wherein the elastic member has a ring shape in which a bottom and a top are flat.

8. The multi-display device of claim 7 , wherein an inner diameter of the ring shape is smaller than an outer diameter of the pillar portion.

9. The multi-display device of claim 6 , wherein the elastic member is more deformed in a width direction of the elastic member than in a height direction of the elastic member.

10. The multi-display device of claim 6 , wherein when the display module is completely closely contacted with the frame, an adjustment height is 0.5 mm, and when the display module is coupled to the frame without form deformation of the elastic member, the adjustment height is 0 mm.

11. The multi-display device of claim 10 , wherein when the adjustment height is 0.5 mm, a top of the elastic member and a top of the pillar portion are positioned substantially at a same location.

12. The multi-display device of claim 10 , wherein when the adjustment height is 0 mm, a top of the elastic member protrudes over a top of the pillar portion.

13. The multi-display device of claim 1 , wherein the display module includes:
a display panel, and
a module cover supporting the display panel, and
wherein the display panel includes a micro light emitting diode (LED).

14. The multi-display device of claim 1 , wherein a maximum length of the pillar portion is smaller than a maximum length of the recess.

15. The multi-display device of claim 14 , wherein a maximum length of the elastic member is a same length as the maximum length of the recess.

16. The multi-display device of claim 1 , wherein the pillar portion protrudes through a portion of the elastic member.

17. The multi-display device of claim 1 , wherein a portion of the display module directly adjacent to a bottom of the recess is curved away from the recess.
