Abstract

Provided are a display device and an augmented reality apparatus including the same. The display device includes a display panel including display blocks and an optics array including pin hole structures that one-to-one correspond to the display blocks. Here, each of the pin hole structures includes a pin hole and a shielding area surrounding the pin hole, and the display blocks are spaced apart from each other in a first direction parallel to a top surface of the display panel and a second direction crossing the first direction and parallel to the top surface of the display panel.

First claim

What is claimed is:

1. A display device comprising:
a display panel comprising display blocks; and
an optics array comprising pin hole structures that one-to-one correspond to the display blocks,
wherein each of the pin hole structures comprises a pin hole and a shielding area configured to surround the pin hole, and
the display blocks are spaced apart from each other in a first direction parallel to a top surface of the display panel and a second direction crossing the first direction and parallel to the top surface of the display panel.

2. The display device of claim 1 , wherein the display panel and the optics array are spaced apart from each other in a third direction perpendicular to the first direction and the second direction.

3. The display device of claim 2 , further comprising a spacer disposed between the display panel and the optics array.

4. The display device of claim 3 , wherein a thickness of the spacer in the third direction is about 0.1 mm to about 10 mm.

5. The display device of claim 2 , wherein each of the pin hole structures overlaps at least a portion of one of the display blocks in the third direction.

6. The display device of claim 2 , wherein a width of the shielding area is proportional to a spaced distance between the display panel and the optics array in the third direction.

7. The display device of claim 2 , wherein a resolution of each of the display blocks is inversely proportional to a spaced distance between the display panel and the optics array in the third direction.

8. The display device of claim 1 , wherein each of the display blocks comprises an organic light emitting diode (OLED).

9. The display device of claim 1 , wherein the display blocks are arranged in a row in the first direction and arranged in a zigzag shape in the second direction.

10. The display device of claim 1 , wherein the display blocks are arranged in a row in the first direction and the second direction.

11. An augmented reality apparatus comprising:
lenses disposed at positions corresponding to eyes of a user;
lens rims configured to surround the lenses, respectively;
temples each connected to an end of each of the lens rims,
wherein each of the lenses comprises:
a display panel comprising display blocks; and
an optics array comprising pin hole structures that one-to-one correspond to the display blocks,
wherein each of the pin hole structures comprises a pin hole and a shielding area configured to surround the pin hole, and
the display blocks are spaced apart from each other in a first direction parallel to a top surface of the display panel and a second direction crossing the first direction and parallel to the top surface of the display panel.

12. The augmented reality apparatus of claim 11 , wherein each of the display blocks comprises a transparent material.

13. The augmented reality apparatus of claim 11 , wherein the display panel and the optics array are spaced apart from each other in a third direction perpendicular to the first direction and the second direction, and
the augmented reality apparatus further comprises a spacer disposed between the display panel and the optics array.

14. The augmented reality apparatus of claim 13 , wherein the spacer comprises a transparent material.

15. The augmented reality apparatus of claim 13 , wherein a thickness of the spacer in the third direction is about 0.1 mm to about 10 mm.

16. The augmented reality apparatus of claim 13 , wherein a width of the shielding area is proportional to a spaced distance between the display panel and the optics array in the third direction.

17. The augmented reality apparatus of claim 13 , wherein a resolution of each of the display blocks is inversely proportional to a spaced distance between the display panel and the optics array in the third direction.

18. The augmented reality apparatus of claim 11 , wherein the display blocks are arranged in a row in the first direction and arranged in a zigzag shape in the second direction.

19. The augmented reality apparatus of claim 11 , wherein the display blocks are arranged in a row in the first direction and the second direction.

20. The augmented reality apparatus of claim 11 , wherein the shielding area prevents images emitted from the display blocks from being transmitted to the eyes of the user without passing through the pin hole.
