a display configured to display the processed image; and

a controller configured to transmit the input image to an adjacent display device provided separately from the display device in the display system through the communication interface, and control the display to display the processed image in a scanning direction based on an arrangement position of the display device within the display system,

wherein the scanning direction of the processed image on the display is opposite to a scanning direction of an image on the adjacent display device, and

wherein the processed image is not inverted when the processed image is displayed in the scanning direction opposite to the scanning direction of the image on the adjacent display device.

2. The display device as claimed in claim 1 , wherein the display is configured to divide the processed image into a plurality of regions, and has a first scan mode for updating the divided regions in a direction from top to bottom of the display and a second scan mode for updating the divided regions in a direction from bottom to top of the display, and

the controller is configured to control the display to display the processed image in the second scan mode.

3. The display device as claimed in claim 1 , wherein the controller is configured to, in response to the adjacent display device rotationally processing a respective image displayed by the adjacent display device, control the display to display the image processed by the image processor with a delay for a predetermined amount of time.

4. The display device as claimed in claim 1 , further comprising a user interface configured to receive an input of a user identifying an arrangement position of the display device in the display system,

wherein the controller is configured to control the display to display the processed image in the scanning direction that is opposite to the scanning direction of the adjacent display device based on arrangement position.

5. The display device as claimed in claim 1 , further comprising a sensor configured to sense an arrangement direction of the display device,

wherein the image processor is configured to rotationally process the image to be displayed on the display device according to the sensed arrangement direction.

6. The display device as claimed in claim 1 , wherein the controller is configured to set a position delay time based on the arrangement position of the display device in the display system, and, in response to the communication interface receiving the input image, the controller is configured to control the display to display the processed image after the position delay time elapses.

7. The display device as claimed in claim 1 , wherein the communication interface is configured to receive the input image from another adjacent display device that is disposed adjacent to the display device in the display system.

8. The display device of claim 1 , wherein the adjacent display device is disposed directly above or directly below the display device within the display system.

9. A display system comprising:

a first display device including a first display and a first communication interface and configured to display an upper region of an input image on the first display; and

a second display device which includes a second display and a second communication interface and is arranged below the first display device and configured to display, on the second display, a lower region of the input image that is on a lower portion of the input image than the upper region,

wherein a scanning direction of the upper region of the input image on the first display of the first display device and a scanning direction of the lower region of the input image on the second display of the second display device are opposite to each other in mutually vertical directions, and

wherein each of images on the first display of the first display device and the second display of the second display device is not inverted when the images are displayed in the scanning directions opposite to each other, and

wherein the first display device is further configured to control the first communication interface to transmit the input image to the second display device via the second communication interface of the second display device.

10. The display system as claimed in claim 9 , wherein the first display device is arranged at a position rotated 180° relative to the second display device and is configured to rotationally process the image to be displayed on the first display of the first display device by inverting the image.

11. A display method of a display device from among a plurality of display devices included in a display system, the display method comprising:

receiving an input image via a first communication interface of the display device;

processing an image of the input image to be displayed; and

transmitting the input image to an adjacent display device via the first communication interface, wherein the adjacent display device is disposed adjacent to and outside the display device in the display system,

displaying, on the display device, the processed image in a scanning direction that is opposite to a scanning direction of an image of the input image on the adjacent display device based on an arrangement position of the display device within the display system,

wherein the processed image is not inverted when the processed image is displayed in the scanning direction opposite to the scanning direction of the image on the adjacent display device.

12. The display method as claimed in claim 11 , wherein the displaying comprises:

dividing the processed image into a plurality of regions, wherein the display device has a first scan mode for updating the divided regions in a direction from top to bottom of the display and a second scan mode for updating the divided regions in a direction from bottom to top of the display; and

displaying the processed image in the second scan mode.

13. The display method as claimed in claim 11 , wherein the displaying comprises, in response to the adjacent display device rotationally processing a respective image, displaying the image processed with a delay for a predetermined time.

14. The display method as claimed in claim 11 , further comprising receiving an input of an arrangement position of the display device within the display system,

wherein the displaying comprises displaying the processed image in the scanning direction that is opposite to the scanning direction of the adjacent display device based on the received arrangement position.

15. The display method as claimed in claim 11 , further comprising sensing an arrangement direction of the display device,

wherein the processing comprises rotationally processing the image to display the image on the display device according to the sensed arrangement direction.

16. The display method as claimed in claim 11 , wherein the displaying comprises setting a position delay time based on the arrangement position of the display device within the display system, and, in response to the input image being received, displaying the processed image after the position delay time elapses.

17. The display method as claimed in claim 11 , wherein the receiving comprises receiving the input image from another adjacent display device that is disposed adjacent to the display device in the display system.

18. A non-transitory computer readable medium having recorded thereon a computer program that is executable by a computer to perform the method of claim 11 .
