4. The method of claim 2, wherein receiving, from the mobile terminal, a second content item comprises:

determining that the first portion of the screen of the display device is not displaying the representation of the first content item, and

based on determining that the first portion of the screen of the display device is not displaying the representation of the first content item,

receiving the second content item from the mobile terminal, and

displaying the second content item at the first portion of the screen of the display device.

5. The method of claim 2,

wherein transmitting, to the mobile terminal, a first content item which is displayed at the first portion of the screen of the display device comprises:

based on a determination that the first portion of the screen of the display device is displaying the representation of the first content item, transmitting, to the mobile terminal, the first content item of which representation is being displayed at the first portion of the screen of the display device, and

based on a determination that the first portion of the screen of the display device is not displaying the representation of the first content item, transmitting, to the mobile terminal, the first content item which is moved to the first portion of the screen of the display device from a second portion of the screen of the display device by a user input.

6. The method of claim 5, wherein transmitting, to the mobile terminal, a first content item which is displayed at the first portion of the screen of the display device further comprises:

performing a copy operation, wherein the copy operation comprises copying the first content item from a storage unit of the display device to the mobile terminal.

7. The method of claim 5, wherein transmitting, to the mobile terminal, a first content item which is displayed at the first portion of the screen of the display device further comprises:

performing a cut operation, wherein the cut operation comprises removing the display of the representation of the first content item from the first portion of the screen of the display device.

8. The method of claim 5, wherein transmitting, to the mobile terminal, a first content item which is displayed at the first portion of the screen of the display device further comprises:

transmitting a copy of the first content item from the display device to the mobile terminal, and

deleting the first content item from a storage unit of the display device immediately after the first content item is transmitted to the mobile terminal.

9. The method of claim 1, wherein the content data comprises at least one of video, text, audio, a photograph, a document file, a game, a representation of a telephone call or a video call, and a software application.

10. The method of claim 1, wherein determining the first portion of the screen of the display device where the mobile terminal is locationally proximate with the display device comprises detecting a touch location of the display device where a rear side of the mobile terminal touches the display device.

11. The method of claim 1, wherein determining the first portion of the screen of the display device where the mobile terminal is locationally proximate with the display device comprises determining a touch location of the mobile terminal with respect to the first portion of the screen of the display device by using at least one of a touch sensor, an Near Field Communication (NFC) tag, and a catadioptric camera in the display device.
