Abstract

A display device includes a frame; and a transparent display module in the frame, the transparent display module including a horizontal cross-section including a closed curve and configured to emit light from opposite surfaces thereof.

Claims

1. A display device comprising:

a frame; and

a transparent display module in the frame, the transparent display module having a horizontal cross-section comprising a closed curve and configured to emit light from opposite surfaces thereof.

2. The display device of claim 1, wherein the horizontal cross-section of the display module has a circularly or ellipsoidally tubular shape.

3. The display device of claim 2, wherein the opposite surfaces of the display module comprise a first light emitting surface configured to display a first image, and a second light emitting surface opposite to the first light emitting surface and configured to display a second image, wherein

the first light emitting surface faces outside in a radial direction of the display module, and the second light emitting surface faces inside in the radial direction of the display module.

4. The display device of claim 3, wherein the first light emitting surface and the second light emitting surface are configured to display images in 360 degrees with respect to a longitudinal central axis of the display module.

5. A display system comprising:

a transparent display module having a horizontal cross-section comprising a closed curve and configured to emit light from opposite surfaces thereof; and

a display region controller configured to control a position of a display region for displaying an image by the display module.

6. The display system of claim 5, wherein the horizontal cross-section of the display module has a circularly or ellipsoidally tubular shape, and

the display module comprises a first light emitting surface facing outside in a radial direction of the display module, and a second light emitting surface facing inside in the radial direction.

7. The display system of claim 6, wherein the display region controller is configured to control the display region of the display module, wherein the display region comprises a first display region and a second display region,

wherein the first display region is a portion of the first light emitting surface and is configured to display a first image, and

wherein the second display region is a portion of the second light emitting surface opposite to the first display region with respect to a longitudinal central axis of the display module, and the second display region is configured to display a second image.

8. The display system of claim 7, further comprising

an image storage configured to store the first image and the second image.

9. The display system of claim 7, further comprising

an image input section configured to input the first image and the second image.

10. The display system of claim 7, wherein the second image is displayed in a same direction as the first image.

11. The display system of claim 10, wherein each of the first display region and the second display region has a circular arc or curve shaped cross-section with an angle of 180 degrees or smaller with respect to the longitudinal central axis.

12. The display system of claim 11, further comprising

a camera configured to photograph a position of a viewer who views the transparent display module,

wherein the display region controller comprises:

a camera controller configured to control the camera according to the position of the viewer; and

a position determiner configured to determine the position of the viewer photographed by the camera, and

wherein the display region controller is configured to control positions of the first display region and the second display region according to the position of the viewer determined by the position determiner.

13. The display system of claim 12, wherein the display region controller is configured to control the first display region and the second display region such that the first image and the second image are displayed in a direction in which the viewer is located.

14. The display system of claim 7, wherein the first image is a foreground image, and the second image is a background image.

15. A display control method of a transparent display module, the transparent display module comprising:

a horizontal cross-section comprising a closed curve,

a first light emitting surface facing externally in a radial direction of the display module, and

a second light emitting surface facing internally in the radial direction, wherein the transparent display module is configured to emit light from the first and second light emitting surfaces, the display control method comprising;

determining a position of a viewer who views the transparent display module; and

respectively providing a first display region on which a first image is displayed and a second display region on which a second image is displayed onto the first light emitting surface and the second light emitting surface in a direction in which the viewer is located.

16. The display control method of claim 15, wherein the determining of the position of the viewer who views the transparent display module comprises:

tracking a position of a face or an eye of the viewer, and

obtaining coordinates of the position of the face or eye of the viewer.

17. The display control method of claim 16, further comprising:

comparing position coordinates of the face or eye with reference position coordinates;

determining a movement amount of the face or eye; and

moving positions of the first display region and the second display region according to the movement amount of the face or eye after determining the position of the viewer who views the transparent display module.
