Abstract

A display device includes display panels; and a specular reflection structure that converts positions of images displayed by the display panels and merges the images at a predetermined position to generate an integrated image, wherein the specular reflection structure includes at least one specular mirror that corresponds to each of the display panels, and the at least one specular mirror converts a display direction by reflecting the images displayed on the display panels wherein a size of each of the images is maintained.

First claim

What is claimed is:

1. A display device comprising:
a plurality of display panels;
a specular reflection structure that converts positions of images displayed by the plurality of display panels and merges the images at a predetermined position to generate an integrated image; and
a display screen that displays the integrated image generated by the specular reflection structure, wherein
the specular reflection structure comprises at least one specular mirror that corresponds to each of the plurality of display panels, and
the at least one specular mirror converts a display direction by reflecting the images displayed on the plurality of display panels, wherein a size of each of the images is maintained, and
wherein the specular reflection structure comprises:
a specular mirror that correspond to one of the plurality of display panels in a 1:1 correspondence, and
a specular mirror group that corresponds to one of the plurality of display panels in a 1:multiple correspondence.

2. The display device of claim 1 , wherein the specular mirror group parallelly moves a display direction of an image displayed on a corresponding one of the plurality of display panels.

3. The display device of claim 2 , wherein the specular mirror that corresponds to one of the plurality of display panels in the 1:1 correspondence converts a display direction of an image displayed on a corresponding one of the plurality of display panels.

4. The display device of claim 3 , wherein the plurality of display panels are disposed in a matrix form on a plane.

5. The display device of claim 3 , wherein the plurality of display panels are disposed on a plurality of planes.

6. The display device of claim 5 , wherein
the plurality of display panels are disposed in a first group and a second group that face each other, and
the specular reflection structure is disposed between the first group and the second group.

7. The display device of claim 6 , wherein
the at least one specular mirror includes a plurality of specular mirrors, and
the plurality of display panels correspond to the plurality of specular mirrors in a 1:1 correspondence.

8. The display device of claim 1 , wherein the at least one specular mirror comprises a light blocking layer that defines a light incident region or a light emission region.

9. The display device of claim 1 , wherein
the plurality of display panels are disposed in a matrix form on a plane, and
display areas of the plurality of display panels are inclined at a predetermined angle with respect to the plane.

10. The display device of claim 1 , further comprising a light blocking wall that separates each image transmission path of each of the plurality of display panels.

11. The display device of claim 1 , wherein the plurality of display panels are disposed on a plurality of planes.

12. The display device of claim 11 , wherein
the plurality of display panels are disposed in a first group and a second group that face each other, and
the specular reflection structure is disposed between the first group and the second group.

13. The display device of claim 11 , wherein
the at least one specular mirror includes a plurality of specular mirrors, and
the plurality of display panels correspond to the plurality of specular mirrors in a 1:1 correspondence.

14. The display device of claim 1 , wherein the specular reflection structure is configured for aligning boundaries of the images separated between the display panels, causing display of the integrated image without the boundaries.

15. The display device of claim 1 , wherein
each display panel comprises a display area displaying a corresponding image and a non-display area, the images displayed by the plurality of display panels having one or more gaps between the images based on one or more of the non-display areas, and
the specular reflection structure is configured for generating the integrated image based on removing the one or more gaps between the images.
