Abstract

A multi-display apparatus includes; a first display panel including a first display device, and a second display panel including a second display device, wherein pixels of the first display panel are vertically aligned with pixels of the second display panel in an area where the first display panel and the second display panel overlap.

Claims

1. A multi-display apparatus comprising:

a first display panel comprising a first display device; and

a second display panel comprising a second display device,

wherein pixels of the first display panel are vertically aligned with pixels of the second display panel in an area where the first display panel and the second display panel overlap.

2. The multi-display apparatus of claim 1, wherein a length of an overlapping portion where the pixels of the first display panel are vertically aligned with the pixels of the second display panel is determined based on a distance between the first display device and the second display device, and based on a viewing angle which is substantially normal to at least one of the first display panel and the second display panel.

3. The multi-display apparatus of claim 2, wherein the length of the overlapping portion is determined according to the following equation:

l=d×

tan(θ

)

wherein, l represents the length of the overlapping portion where the pixels of the first display panel are vertically aligned with the pixels of the second display panel, d represents the distance between the first display device and the second display device, and θ

represents the viewing angle which is substantially normal to at least one of the first display panel and the second display panel.

4. The multi-display apparatus of claim 1, wherein a size of the pixels of the second display panel that overlap the pixels of the first display panel is substantially equal to or smaller than a size of non-overlapping pixels of the second display panel.

5. The multi-display apparatus of claim 1, wherein a luminance level of the pixels of the second display panel that overlap the pixels of the first display panel is substantially equal to or lower than a luminance level of non-overlapping pixels of the second display panel.

6. The multi-display apparatus of claim 1, wherein the pixels of the second display panel that overlap the pixels of the first display panel have a smaller size and a higher luminance level than non-overlapping pixels of the second display panel.

7. The multi-display apparatus of claim 1, wherein substantially the same image signal is transmitted to the pixels of the first display panel that are vertically aligned with the pixels of the second display panel and the pixels of the second display panel that are vertically aligned with the pixels of the first display panel.

8. The multi-display apparatus of claim 1, wherein a length of an overlapping portion where the pixels of the first display panel are vertically aligned with the pixels of the second display panel is about 0.1 to about 3 times a pixel length.

9. The multi-display apparatus of claim 1, wherein

the first display panel further comprises:

a first substrate on which the first display device is disposed; and

a first cover which covers and protects the first display device, and

wherein the second display panel further comprises;

a second substrate on which the second display device is disposed; and

a second cover which covers and protects the second display device.

10. The multi-display apparatus of claim 1, wherein the first display panel and the second display panel are interconnected to allow the multi-display apparatus to be foldable.

11. The multi-display apparatus of claim 10, wherein the multi-display apparatus further comprises a hinge attached to edges of the first display panel and the second display panel.

12. The multi-display apparatus of claim 1, wherein each of the first display device and the second display device is one of a liquid crystal display device, a field emission display device, a plasma display panel, and an organic light-emitting diode.
