Abstract

A terminal and controlling method thereof are disclosed that enable data of a first terminal to be executed in a second terminal. Accordingly, all functions of the first terminal are usable using the second terminal.

Claims

1. A terminal, comprising:

a wireless communication unit configured to communicate with an external terminal;

a display unit; and

a control unit, when content information exists within screen information for display on the display unit, the control unit is configured to display the screen information including notification information indicative of the content information on the display unit, and the control unit is further configured to transmit the as displayed screen information including the notification information to the external terminal.

2. The terminal of claim 1, wherein the notification information is as least one of a text, an image, an icon, an animation, a watermark and a barcode.

3. The terminal of claim 1, wherein when a request for the content information corresponding to the notification information is received from the external terminal, the control unit distinguishes a type of the content information, executes an application for the content information and transmits screen information indicative of the execution of the application to the external terminal.

4. The terminal of claim 1, wherein, when an event occurs at the terminal, the control unit displays another notification information indicating the occurring of the event within the screen information and transmits event screen information indicative of the occurring of the event that includes the another notification information to the external terminal.

5. The terminal of claim 4, wherein the event includes at least one of a phone call, an email, a message, and an alarm.

6. The terminal of claim 4, wherein, when an event screen request signal corresponding to the another notification information is received from the external terminal, the control unit displays event screen information corresponding to the event and transmits the event screen information to the external terminal.

7. The terminal of claim 1, wherein, when communication is established with the external terminal, the control unit adjusts a display brightness of a screen of the display unit to a predetermined brightness.

8. The terminal of claim 7, wherein, when no longer communicating with the external terminal, the control unit turns off the display unit or reduces the display brightness of the screen of the display unit to a level equal to or lower than the predetermined brightness.

9. The terminal of claim 1, further comprising:

a user input unit having a backlight unit configured to apply light to the user input unit, wherein, when communicating with the external terminal, the control unit adjusts a brightness of the backlight unit to a predetermined brightness.

10. The terminal of claim 9, wherein, when no longer communicating with the external terminal, the control unit turns off the backlight unit or adjusts the brightness of the backlight unit to a level equal to or lower than the predetermined brightness.

11. The terminal of claim 1, wherein, when there is no variation of the screen information transmitted to the external terminal for a predetermined duration, the control unit stops communicating with the external terminal.

12. The terminal of claim 11, wherein while the communicating is stopped, if the screen information transmitted to the external terminal varies, the control unit resumes communicating with the external terminal.

13. A method of controlling a terminal having a display, the method comprising:

establishing communication with an external terminal;

when content information exists within screen information to display, displaying the screen information including a notification information indicative of the content information on the display; and

transmitting the as displayed screen information including the notification information to the external terminal.

14. A terminal, comprising:

a wireless communication unit configured to establish communication with an external terminal, the wireless communication unit is configured to receive screen information including notification information indicative of content information existing within the screen information as is displayed on a screen of the external terminal;

a display unit configured to display the received as displayed screen information including the notification information; and

a control unit, when the notification information is selected in the terminal, the control unit is configured to request execution screen information of the content information corresponding to the notification information to the external terminal, and the control unit is configured to display the execution screen information received from the external terminal on the display unit.

15. The terminal of claim 14, wherein, when the notification information is selected, the control unit transmits a request signal for the content information corresponding to the notification information to the external terminal, receives the execution screen information of the content information corresponding to the request signal from the external terminal, and then displays the received execution screen information on the display unit.

16. The terminal of claim 14, wherein, when an event occurs at the external terminal, the control unit receives another notification information indicating an occurring of the event from the external terminal via the wireless communication unit and then displays the received another notification information on the display unit.

17. The terminal of claim 16, wherein the event includes at least one of a phone call, an email, a message, and an alarm.

18. The terminal of claim 16, wherein, when the another notification information is selected in the terminal, the control unit transmits a request signal for the event screen corresponding to the another notification information to the external terminal, receives the event screen information corresponding to the another notification information from the external terminal, and then displays the received event screen information on the display unit.

19. The terminal of claim 14, further comprising:

a memory having a communication connection authenticated device information list, wherein, when a device information of the external terminal is selected from the list, the control unit establishes the communication by searching for the external terminal during a predetermined cycle using the selected device information.

20. The terminal of claim 14, wherein, when the screen information received from the external device does not vary for a predetermined duration, the control unit stops communicating with the external terminal.

21. The terminal of claim 20, wherein, while the communicating is stopped, if the screen information received from the external terminal varies, the control unit resumes communicating with the external terminal.

22. The terminal of claim 14, further comprising:

a input unit, wherein when a key signal for an operation control of the external terminal is not input from the user input unit for a predetermined duration, the control unit stops communicating with the external terminal.

23. The terminal of claim 22, wherein while the communicating is stopped, if the key signal for the operation control of the external terminal is input from the user input unit, the control unit resumes communicating with the external terminal.

24. A method of controlling a terminal having a display, the method comprising:

establishing communication with an external terminal;

receiving screen information including notification information indicative of content information existing within the screen information as is displayed on a screen of the external terminal;

displaying the received as displayed screen information including the notification information;

when the notification information is selected in the terminal, requesting execution screen information of the content information corresponding to the notification information to the external terminal;

receiving the execution screen information from the external terminal; and

displaying the received execution screen information on the display.
