Abstract

A display device can include a communication unit to receive first data from the external device; a display unit to display first screen information based on the first data; and a control unit to receive an content selection and transmit location information corresponding to the selected content to the external device for executing a function, and receive second data from the external device that is based on the executed function, and display second screen information based on the received second data, in which the first data is related to contents displayed in the external device before receiving the location information, the second data is related to contents displayed in the external device after receiving the location information and executing the function based on the location information from the external device, the location information includes coordinate information that are coordinates of the selected content in the displayed first screen information.

Claims

1. A display device comprising:

a communication unit configured to establish communication with an external device, wherein the communication unit is further configured to receive first data from the external device;

a display unit configured to display first screen information based on the received first data on the display unit; and

a control unit configured to receive an input signal for selecting content and transmit location information corresponding to the selected content to the external device for executing a function based on the location information in the external device, and receive second data from the external device, wherein the second data is based on the executed function,

wherein the control unit is further configured to display second screen information based on the received second data on the display unit,

wherein the first data is related to contents displayed in the external device before receiving the location information from the display device,

wherein the second data is related to contents displayed in the external device after receiving the location information from the display device and executing the function based on the location information from the external device,

wherein the location information includes coordinate information, and

wherein the coordinate information are coordinates of the selected content in the first screen information displayed on the display unit.

2. The display device of claim 1, wherein the controller is further configured to receive an authentication access request from the external device and the controller is further configured to grant the authentication access request.

3. The display device of claim 1, wherein the controller is further configured to receive an authentication access request from the external device and the controller is further configured to grant the authentication access request, when the display device initially receives authentication access request from the external device.

4. The display device of claim 2, wherein the controller is further configured to add the granted external device in an access authentication device list of connected external devices.

5. The display device of claim 1, wherein the first screen information includes a virtual manipulation unit corresponding to a manipulation unit provided at a main body of the external device.

6. The display device of claim 5, wherein the controller is further configured to transmit signals for controlling the external device via the virtual manipulation unit displayed on the display unit.

7. The display device of claim 1, wherein the display unit is further configured to display one or more external devices connected to the display device.

8. The display device of claim 1, wherein the display unit further displays a notification regarding an event occurred in the external device.

9. A method of controlling a display device, the method comprising:

establishing communication with an external device to receive first data from the external device;

displaying first screen information based on the received first data on a display unit of the display device;

receiving an input signal for selecting content and transmitting location information corresponding to the selected content to the external device for executing a function based on the location information in the external device, and receiving second data from the external device, wherein the second data is based on the executed function; and

displaying the second screen information based on the received second data on the display unit,

wherein the first data is related to contents displayed in the external device before receiving the location information from the display device,

wherein the second data is related to contents displayed in the external device after receiving the location information from the display device and executing the function based on the location information from the external device,

wherein the location information includes coordinate information, and

wherein the coordinate information are coordinates of the selected content in the first screen information displayed on the display unit.

10. The method of claim 9, wherein the display device receives an authentication access request from the external device and the display device grants the authentication access request.

11. The method of claim 10, wherein the display device receives an authentication access request from the external device and the display device grants the authentication access request, when the display device initially receives authentication access request from the external device.

12. The method of claim 10, wherein the display device adds the granted external device in an access authentication device list of connected external devices.

13. The method of claim 9, wherein the first screen information includes a virtual manipulation unit corresponding to a manipulation unit provided at a main body of the external device.

14. The method of claim 13, wherein the display device transmits signals for controlling the external device via the virtual manipulation unit displayed on the display unit.

15. The method of claim 9, wherein the display unit displays one or more external devices connected to the display device.

16. The method of claim 9, wherein the display unit displays a notification regarding an event occurred in the external device.
