Abstract

A display device is disclosed. In one aspect, the display device includes a first display unit including a first display area, a first left pad area outside a first left end portion of the first display area, and a first right pad area outside a first right end portion of the first display area. The first right end portion is opposite to the first left end portion. The first display unit is bent at a first portion between the first display area and the first left pad area and bent at a second portion between the first display area and the first right pad area. The first display area is bent such that the first left and right end portions are adjacent to each other, and the first left and right pad areas are located inside the first display unit. The display device also includes a first printed circuit board corresponding to both the first left and right pad areas.

First claim

What is claimed is:

1. A display device comprising:
a first display unit comprising a first display area, a first left pad area outside a first left end portion of the first display area, and a first right pad area outside a first right end portion of the first display area, wherein the first right end portion is opposite to the first left end portion, wherein the first display unit is bent at a first portion between the first display area and the first left pad area and bent at a second portion between the first display area and the first right pad area, wherein the first display area is bent such that the first left and right end portions are adjacent to each other, and wherein the first left and right pad areas are located inside the first display unit; and
a first printed circuit board positioned over at least a portion of both the first left and right pad areas.

2. The display device of claim 1 , wherein the first and second portions are bent such that a rear surface of the first left pad area and a rear surface of the first display area face each other and a rear surface of the first right pad area and the rear surface of the first display area face each other.

3. The display device of claim 2 , wherein the first printed circuit board contacts both the first left and right pad areas.

4. The display device of claim 3 , wherein the first printed circuit board is bonded to each of the first left and right pad areas so as to maintain a state in which the first display area is bent.

5. The display device of claim 1 , further comprising:
a second display unit comprising a second display area, a second left pad area outside a second left end portion of the second display area, and a second right pad area outside a second right end portion of the second display area, wherein the second right end portion is opposite to the second left end portion, wherein the second display unit is bent at a third portion between the second display area and the second left pad area and bent at a fourth portion between the second display area and the second right pad area, wherein the second display area is bent such that the second left and right end portions are adjacent to each other, and wherein the second left and right pad areas are located inside the second display unit; and
a second printed circuit board positioned over at least a portion of both the second left and right pad areas.

6. The display device of claim 5 , wherein the third and fourth portions are bent such that a rear surface of the second left pad area and a rear surface of the second display area face each other and a rear surface of the second right pad area and the rear surface of the second display area face each other.

7. The display device of claim 5 , wherein the second printed circuit board contacts both the second left and right pad areas.

8. The display device of claim 7 , wherein the second printed circuit board is bonded to each of the second left and right pad areas so as to maintain a state in which the second display area is bent.

9. The display device of claim 5 , wherein the first and second printed circuit boards form a single body.

10. The display device of claim 5 , further comprising a connection unit connecting the first and second display units,
wherein the first and second display units are arranged to maintain a first interval.

11. The display device of claim 10 , wherein the connection unit comprises a first connection unit and a second connection unit connecting the first and second display units at different positions.

12. The display device of claim 10 , wherein the first display unit comprises a first substrate, wherein the second display unit comprises a second substrate, and wherein the connection unit comprises a third substrate that connects the first substrate and the second substrate.

13. The display device of claim 12 , wherein the first, second and third substrates form a single body.

14. The display device of claim 1 , further comprising a plurality of first left pads electrically connected to scan lines in the first display area arranged in the first left pad area and a plurality of first right pads electrically connected to data lines in the first display area arranged in the first right pad area.

15. A display device comprising:
a first display unit comprising a first display area, a first left pad area and a first right pad area, wherein the first display area has a first partially cone shape and configured to display a first image in 360 degrees, and wherein the first left and right pad areas contact each other and are located at an inner surface of the first display area; and
a first printed circuit board connected to the first left and right pad areas.

16. The display device of claim 15 , wherein the first printed circuit board directly contacts both the first left and right pad areas.

17. The display device of claim 15 , further comprising:
a second display unit comprising a second display area, a second left pad area and a second right pad area, wherein the second display area has a second partially cone shape and is smaller than the first display area, wherein the second display area is configured to display a second image in 360 degrees, wherein the second left and right pad areas contact each other and are located at an inner surface of the second display area, and wherein a bottom portion of the second display unit is connected to a top portion of the first display unit such that the combined first and second display units have a substantially cone shape; and
a second printed circuit board connected to the first left and right pad areas.

18. The display device of claim 17 , wherein the second printed circuit board directly contacts both the second left and right pad areas.

19. The display device of claim 17 , further comprising a connector connecting the first and second display units such that the bottom portion of the second display unit does not directly contact the top portion of the first display unit.

20. The display device of claim 17 , wherein the first and second images are different from each other.
