Abstract

A display system and method of a portable phone using an external display device are provided, in which application data is displayed, a user input information presentation mode is activated while the application data is displayed, and a user input information corresponding to a signal is presented on the application data, if the signal is input in the user input information presentation mode.

Claims

1. A display method of a portable device having an internal display and connected to an external display, comprising:

displaying application data;

activating a user input information presentation mode, while the application data is displayed; and

presenting on the application data a user input information corresponding to a signal, if the signal is input in the user input information presentation mode.

2. The display method of claim 1, wherein the application data comprises a text document, a still picture, and a motion picture.

3. The display method of claim 1, wherein the application data is displayed on at least one of the internal display and external display.

4. The display method of claim 1, wherein the user input information is overlaid on the application data.

5. The display method of claim 1, wherein the user input information comprises at least one of a line drawing, a diagram drawing, a pointer movement, and a character input on the internal and external displays.

6. The display method of claim 1, wherein the user input information is displayed on at least one of the internal display and external display.

28. The method of claim 1, further comprising processing the user input information presented on the application data.

29. The method of claim 1, further comprising storing an application for establishing a connection between a portable device and an external display, and the application data.

7. A display method of a portable device having an internal display and connected to an external display, comprising:

displaying application data on an external display;

activating a user input information presentation mode, while the application data is displayed;

determining whether an event occurs in the user input information presentation mode; and

presenting on the application data a user input information corresponding to an event, if the event occurs.

8. The display method of claim 7, wherein the determining of whether the event occurs comprises:

determining whether an input is performed; and

generating the user input information corresponding to the input.

9. The display method of claim 7, wherein the determining of whether the event occurs comprises:

determining whether an event is detected by a sensor;

generating an event signal corresponding to the event;

generating the user input information corresponding to the event signal.

10. The display method of claim 9, wherein the event signal includes a spatial displacement of the portable device.

11. The display method of claim 7, further comprising:

determining whether an input for storing the application data and the user input information as a combined image is performed; and

storing the combined image, if the input for storing the application data and the user input information is performed.

12. The display method of claim 7, wherein the user input information comprises at least one of a line drawing, a diagram drawing, a pointer movement, and a character input.

13. The display method of claim 7, wherein the application data comprises at least one of a text document, a still picture, and a motion picture.

14. The display method of claim 7, wherein the application data is displayed on at least one of the internal display and external display.

15. The display method of claim 7, wherein the user input information is displayed on at least one of the internal display and external display.

30. The method of claim 7, further comprising processing the user input information presented on the application data.

31. The method of claim 7, further comprising storing an application for establishing a connection between a portable device and an external display, and the application data.

16. A display system of a portable device having an internal display and connected to an external display, the display system comprising:

a memory for storing an application for establishing connection between a portable device and an external display, presenting application data and user input information, and storing the application data;

a screen image processing unit for processing the user input information presented on the application data; and

a controller for controlling the portable device to operate in a user input information presentation mode, in which user input information is presented on the application in real time according to a mode selection input.

17. The display system of claim 16, further comprising a keypad comprising a plurality of keys for performing key inputs.

18. The display system of claim 16, further comprising a displacement detector for detecting a spatial displacement of the portable device, wherein the spatial displacement is analyzed as user input information.

19. The display system of claim 16, further comprising a connection interface for interfacing the portable phone with the external display.

20. The display system of claim 19, wherein the connection interface comprises at least one of a wire interface module and a wireless interface module.

21. The display system of claim 16, wherein the user input information is presented overlaid on the application data.

22. The display system of claim 21, wherein the application data comprises at least one of a text document, a still picture, and a motion picture.

23. The display system of claim 21, wherein the application data is displayed on at least one of the internal display and external display.

24. The display system of claim 21, wherein the user input information is represented by at least one of a line drawing, a diagram drawing, a pointer movement, and a character input on the internal and external displays.

25. The display system of claim 21, wherein the user input information is displayed on at least one of the internal display and external display.

26. The display system of claim 16, wherein the application data and the user input information are stored as a combined image in the memory.

27. The display system of claim 26, wherein the application data and the user input information are stored separately in the memory.
