1. A mobile terminal, comprising:

a first display unit configured to display at least one of a first home screen image and a second home screen image as an output home screen image;

an interface unit configured to be connected to an external display device, the external display device configured to be controlled by a microprocessor and having a second display unit; and

a controller configured to generate a monitor window including a copy of the output home screen image displayed on the first display unit of the mobile terminal and to control the external display device to simultaneously display the generated monitor window on the second display unit of the external display device.

2. The mobile terminal of claim 1, wherein the controller is further configured to transmit information to the external display device corresponding to the displayed first and second home screen images, and to control the external display device to simultaneously display the first and second home screen images in the monitor window on the external display device.

3. The mobile terminal of claim 2, wherein the controller is further configured to control the external display device to display each of the first and second home screen images in separate monitor windows on the second display unit.

4. The mobile terminal of claim 2, wherein the controller is further configured to control the external display device to highlight a respective one of the first and second home screen images displayed in the monitor window that corresponds to the one of the first and second home screen images displayed as the output home screen image on the mobile terminal.

5. The mobile terminal of claim 1, wherein each of the first and second home screen images includes at least one object, and

wherein if one object is selected and deleted from the first home screen image or is shifted to the second home screen image on the second display unit, the controller is further configured to control the selected object to be deleted from the first home screen image or to be shifted to the second home screen image on the first display unit of the mobile terminal.

6. The mobile terminal of claim 2, wherein if one of the first and second home screen images displayed in the monitor window on the second display unit of the external display device is selected, the controller is further configured to display the selected one of the first and second home screen images on the first display unit of the mobile terminal.

7. The mobile terminal of claim 2, wherein the controller is further configured to receive an input signal requesting the first and second home screen images to be sequentially displayed as the output home screen image on the first display unit in a prescribed display order, and

wherein if an arrangement of the first and second home screen images displayed in the monitor window on the second display unit is adjusted, the controller is further configured control the first display unit to display the first and second home screen images as the output home screen image in a display order that matches the adjusted arrangement.

8. The mobile terminal of claim 1, wherein if one of the first and second home screen images displayed as the output home screen image is zoomed in or zoomed out on the first display unit, the controller is further configured to control the second display unit of the external display device to zoom in or zoom out the corresponding first or second home screen image displayed in the monitor window of the external display device.

9. The mobile terminal of claim 4, wherein at least one of the first and second home screen images includes at least one object, and

wherein the controller is further configured to receive a selection signal indicating a selection of an object on said one of the first and second home screen images displayed as the home screen image on the first display unit, to execute a corresponding application and display an image of the executed application on the first display unit, and to control the second display unit of the external display device to display the same application image on the monitor window in the second display unit.

10. (canceled)

11. A display device configured to be controlled by a microprocessor, comprising:

an interface unit configured to be connected to a mobile terminal having a first display unit configured to display at least one of a first home screen image and a second home screen image as an output home screen image on the first display unit;

a second display unit; and

a controller configured to generate a monitor window including a copy of the output home screen image displayed on the first display unit and to control the second display unit to simultaneously display the generated monitor window on the second display unit.

12. The display device of claim 11, wherein the controller is further configured to receive information from the mobile terminal corresponding to the displayed first and second home screen images, and to control the second display unit to simultaneously display the first and second home screen images in the monitor window on the second display unit.

13. The display device of claim 12, wherein the controller is further configured to control the second display unit to display each of the first and second home screen images in separate monitor windows on the second display unit.

14. The display device of claim 12, wherein the controller is further configured to control the second display unit to highlight a respective one of the first and second home screen images displayed in the monitor window that corresponds to the one of the first and second home screen images displayed as the output home screen image on the mobile terminal.

15. The display device of claim 11, wherein each of the first and second home screen images includes at least one object, and

wherein if one object is selected and deleted from the first home screen image or is shifted to the second home screen image on the second display unit, the controller is further configured to control the selected object to be deleted from the first home screen image or to be shifted to the second home screen image on the first display unit of the mobile terminal.

16. The display device of claim 12, wherein if one of the first and second home screen images displayed in the monitor window on the second display unit is selected, the controller is further configured to display the selected one of the first and second home screen images on the first display unit of the mobile terminal.

17. The display device of claim 12, wherein the controller is further configured to receive an input signal requesting the first and second home screen images to be sequentially displayed as the output home screen image on the first display unit in a prescribed display order, and

wherein if an arrangement of the first and second home screen images displayed in the monitor window on the second display unit is adjusted, the controller is further configured control the first display unit to display the first and second home screen images as the output home screen image in a display order that matches the adjusted arrangement.

18. The display device of claim 11, wherein if one of the first and second home screen images displayed as the output home screen image is zoomed in or zoomed out on the first display unit, the controller is further configured to control the second display unit to zoom in or zoom out the corresponding first or second home screen image displayed in the monitor window.

19. The display device of claim 14, wherein at least one of the first and second home screen images includes at least one object, and

wherein the controller is further configured to receive a selection signal indicating a selection of an object on said one of the first and second home screen images displayed as the home screen image on the first display unit, to execute a corresponding application and display an image of the executed application on the first display unit, and to control the second display unit to display the same application image on the monitor window in the second display unit.
