Abstract

A multi-display device includes: a plurality of display devices disposed adjacent to each other; and a plurality of optical apparatuses disposed on at least a part of a display area and a non-display area of a respective one of the plurality of display devices, wherein each of the plurality of optical apparatuses comprises: a transparent body having a side surface substantially perpendicular to one surface of the display device and a first inclined surface disposed to face the non-display area; and a reflective member disposed on the side surface and the first inclined surface.

First claim

What is claimed is:

1. A multi-display device comprising:
a plurality of display devices disposed adjacent to each other; and
a plurality of optical apparatuses disposed on at least a part of a display area and a non-display area of a respective one of the plurality of display devices,
wherein each of the plurality of optical apparatuses comprises:
a transparent body having a side surface substantially perpendicular to one surface of the display device and a first inclined surface disposed to face the non-display area; and
a reflective member disposed on the side surface and the first inclined surface.

2. The multi-display device of claim 1 , wherein the optical apparatus is symmetric with respect to a boundary surface between the plurality of display devices.

3. The multi-display device of claim 2 , wherein the optical apparatus further comprises a second inclined surface between the side surface and the first inclined surface.

4. The multi-display device of claim 3 , further comprising an adhesive between the first inclined surface and the non-display area.

5. The multi-display device of claim 2 , wherein the optical apparatus further comprises a second inclined surface between the side surface and a lower surface.

6. The multi-display device of claim 5 , further comprising an adhesive between the lower surface and the display area.

7. The multi-display device of claim 1 , wherein the first inclined surface has an inclination angle of 10 to 80 degrees.

8. The multi-display device of claim 3 , wherein the second inclined surface has an inclination angle of 10 to 80 degrees.

9. The multi-display device of claim 5 , wherein the second inclined surface has an inclination angle of 10 to 80 degrees.

10. The multi-display device of claim 2 , wherein the optical apparatus has a convexly formed upper surface.

11. The multi-display device of claim 2 , wherein the optical apparatus has a concavely formed upper surface.

12. The multi-display device of claim 1 , wherein the transparent body comprises at least one substance selected from polycarbonate (PC), polymethylmethacrylate (PMMA), acrylonitrile-butadiene-styrene (ABS) copolymer and acrylic resins.

13. The multi-display device of claim 1 , wherein the reflective member comprises at least one substance selected from gold (Au), silver (Ag), copper (Cu), aluminum (Al), chromium (Cr), titanium (Ti), and alloys thereof.

14. A multi-display device comprising:
a plurality of display devices disposed adjacent to each other; and
a plurality of optical apparatuses disposed on at least a part of a display area and a non-display area of a respective one of the plurality of display devices,
wherein each of the optical apparatuses comprises:
a transparent body having a side surface substantially perpendicular to one surface of the display device and a first inclined surface disposed to face the non-display area; and
an externally reflective member disposed on the side surface and another reflective member disposed on the first inclined surface,
the reflective member disposed on the side surface having a top edge with a height greater than the first inclined surface.

15. The multi-display device of claim 14 , wherein the height of the top edge is defined within a range between about 2.5 mm or more and 3.5 mm or less.

16. The multi-display device of claim 6 , wherein the adhesive is a transparent adhesive.

17. The multi-display device of claim 15 , wherein the reflective member disposed on the side surface being flat.

18. The multi-display device of claim 15 , wherein the reflective member is formed of polyethylene terephthalate (PET).

19. The multi-display device of claim 17 , wherein a major surface of the reflective member is coated with a material containing metal including silver.

20. The multi-display device of claim 17 , wherein a major surface of the reflective member is coated with a diffusion layer containing an inorganic oxide including titanium oxide.
