a display configured to receive a touch input,

wherein the coupling controller hardware device is further configured to;

identify a touch input on the display as the content transfer request and to request for status information to a peripheral device,

store a time of recognition at which a touch is recognized and a time of cancellation at which the touch is cancelled, and

compare the time of recognition and the time of cancellation with recognition information, the recognition information being acquired by using a proximity sensor within the user equipment, when the recognition information is received from the user equipment as the status information, and to perform coupling with the user equipment based upon the compared result.

2. The device of claim 1,

wherein the coupling controller hardware device is further configured to:

generate touch information respective to the touch input, when the touch input is recognized, and

compare the touch information with recognition information within the user equipment, when the recognition information is received from the user equipment as the status information, and to perform coupling with the user equipment based upon the compared result.

3. The device of claim 2, wherein the recognition information includes at least one a movement time, movement distance, and movement pattern of the user equipment, and

wherein the coupling controller hardware device performs coupling with the user equipment, when the recognition information corresponds to the touch information.

4. The device of claim 1, further comprising:

a camera flash, and

wherein the coupling controller hardware device is further configured to;

display an image code through the display or the camera flash, when the touch input is recognized, and

compare the image code with a code value, when the code value recognized by the user equipment is received from the user equipment as the status information, and to perform coupling with the user equipment based upon the compared result.

5. The device of claim 4, wherein the image code includes information for identifying the content, and

wherein the image code is configured as a code being displayed as a pattern having at least one pre-decided color or as a barcode or a Quick Response (QR) code.

6. The device of claim 4, wherein the code value corresponds to a value of recognizing the image code displayed on the display by the user equipment by using at least one of an illuminance sensor, a camera, an RGB sensor, and an image sensor.

7. The device of claim 1, wherein the recognition information includes a first time of change at which the proximity sensor recognizes access of an object, and a second time of change at which access of the object is cancelled, and

wherein the coupling controller hardware device performs coupling with the user equipment in accordance with whether or not the first time of change corresponds to a time prior to the time of recognition and whether or not the second time of change corresponds to a time after the time of cancellation.

8. The device of claim 1, wherein the coupling controller hardware device transmits a device search message to a peripheral device existing within a predetermined distance range, the device search message being used for searching the user equipment, or wherein the coupling controller hardware device requests a server for a transmission of the device search message by using a user equipment list, the server including a user equipment list related to the display device, when the content transfer request is recognized.
