The display device according to various exemplary embodiments includes a display, a communicator configured to communicate with an external device, a first nearby device, and a second nearby device, and a processor configured to control the communicator to transmit each of a first image which is received from the external device and a second image which is received from the first nearby device to the second nearby device, and control the display to display at least one of the first image and the second image. ## Claims ### Claim 1 A display device comprising: a display; a communicator configured to communicate with an external device, a first nearby device, and a second nearby device; and a processor configured to control the communicator to transmit each of a first image which is received from the external device and a second image which is received from the first nearby device to the second nearby device, and control the display to display at least one of the first image and the second image. ### Claim 2 (depends on 1) The device as claimed in claim 1, wherein the communicator receives device information on the external device from the external device and receives device information on a second external device corresponding to the second image from the first nearby device, wherein the processor generates an image source list using the received device information of the external device and the device information of the second external device, and controls the display to display the generated image source list. ### Claim 3 (depends on 2) The device as claimed in claim 2, further comprising: an input unit configured to receive a control command to select an image source, wherein the processor, in response to a control command to select the external device as an image source being received, controls the display to display the first image, and in response to a control command to select the second external device as an image source being received, controls the display to display the second image. ### Claim 4 (depends on 1) The device as claimed in claim 1, wherein the processor controls the display to display a predetermined area out of the received first image or second image based on a position of the display device, the first nearby device and the second nearby device. ### Claim 5 (depends on 1) The device as claimed in claim 1, wherein the processor synthesizes the first image and the second image to generate a synthesized image, and controls the communicator to transmit the synthesized image to the second nearby device. ### Claim 6 (depends on 5) The device as claimed in claim 5, further comprising: an input unit configured to receive a control command to select a part of an area which is to be displayed in the display from the synthesized image, wherein the processor controls the display to display only a part of an area corresponding to the control command from the synthesized image. ### Claim 7 (depends on 1) The device as claimed in claim 1, wherein the communicator receives, from the first nearby device, a control command regarding the display device, wherein the processor performs an operation corresponding to the received control command. ### Claim 8 (depends on 1) The device as claimed in claim 1, wherein the communicator receives, from the first nearby device, a control command regarding the second nearby device, and the processor controls the communicator to transmit the received control command regarding the second nearby device to the second nearby device. ### Claim 9 A control method of a display device, the method comprising: connecting with a first nearby device and a second nearby device; connecting with an external device; transmitting each of a first image received from the external device and a second image received from the first nearby device to the second nearby device; and displaying at least one of the first image and the second image. ### Claim 10 (depends on 9) The method according to claim 9, further comprising: receiving device information of the external device from the external device; receiving device information on the second external device corresponding to the second image from the first nearby device; generating an image source list using the received device information of the external device and the device information of the second external device; and displaying the generated image source list. ### Claim 11 (depends on 10) The method according to claim 10, further comprising: receiving a control command to select an image source, wherein the displaying comprises, in response to a control command to select the external device as an image source being received, displaying the first image, and in response to a control command to select the second external device as an image source being received, displaying the second image. ### Claim 12 (depends on 9) The method according to claim 9, wherein the displaying comprises displaying a predetermined area out of the received first image or second image based on a position of the display device, the first nearby device and the second nearby device. ### Claim 13 (depends on 9) The method according to claim 9, further comprising: synthesizing the first image and the second image to generate a synthesized image; and transmitting the synthesized image to the second nearby device. ### Claim 14 (depends on 13) The method according to claim 13, further comprising: receiving a control command to select a part of an area which is to be displayed in the display device from the synthesized image, wherein the displaying comprises displaying only a part of an area corresponding to the control command from the synthesized image. ### Claim 15 (depends on 9) The method according to claim 9, further comprising: receiving, from the first nearby device, a control command regarding the display device; and performing an operation corresponding to the received control command. ### Claim 16 (depends on 9) The method according to claim 9, further comprising: receiving, from the first nearby device, a control command regarding the second nearby device; and transmitting the received control command regarding the second nearby device to the second nearby device. ### Claim 17 A display system comprising: an external device which stores content; and a plurality of display devices, wherein a first display device which directly receives a first image corresponding to a content stored in the external device from among the plurality of display devices transmits each of the received first image and a second image received from the second display device to a third display device, and displays at least one of the first image and the second image. ### Claim 18 (depends on 17) The display system according to claim 17, wherein each of the plurality of display devices is connected to each of two adjacent other devices via wired cable. ### Claim 19 (depends on 17) The display system according to claim 17, further comprising: a second external device which provides a second image to a display device other than the first display device from among the plurality of display devices, wherein the first display device receives device information of the external device from the external device, receives device information of the second external device from the second display device, generates an image source list using the received device information of the external device and device information of the second external device, and displays the generated image source list. ### Claim 20 (depends on 17) The display system according to claim 17, wherein the first display device synthesizes the first image and the second image to generate a synthesized image and transmits the synthesized image to the second display device.
