The method may include establishing a connection to an external display, executing a first application in the mobile terminal, transmitting information associated with the first application to the external display, and displaying a first application window for the first application in a first region of the external display based on the transmitted information. The method may further include receiving a command to display another application window on the external display, moving the first application window for the first application displayed on the first region to a second region of the external display, executing a second application in the mobile terminal, transmitting information associated with the second application to the external display, and displaying a second application window for the second application in the first region of the external display. ## Claims ### Claim 1 A method of controlling a mobile terminal, comprising the steps of: establishing a connection to an external display; executing a first application in the mobile terminal; transmitting information associated with the first application to the external display; displaying a first application window for the first application in a first region of the external display based on the transmitted information; receiving a command to display another application window on the external display; moving the first application window for the first application displayed on the first region to a second region of the external display; executing a second application in the mobile terminal; transmitting information associated with the second application to the external display; and displaying a second application window for the second application in the first region of the external display. ### Claim 2 (depends on 1) The method of claim 1, further comprising displaying a menu in the first region of the external display for selecting the second application among a list of one or more applications in response to the command. ### Claim 3 (depends on 1) The method of claim 1, wherein the application window displayed in the first region of the external display is simultaneously displayed on a display of the mobile terminal. ### Claim 4 (depends on 1) The method of claim 1, further comprising: receiving a command to change the display of the application windows on the external display; detecting an input to scroll the displayed application windows at the mobile terminal; and scrolling the displayed application windows on the external display in response to the detected input. ### Claim 5 (depends on 1) The method of claim 1, further comprising the steps of: determining an orientation of the mobile terminal based on sensed motion of the mobile terminal; and changing a shape of the application window displayed in the first region to correspond to the determined orientation of the mobile terminal. ### Claim 6 (depends on 5) The method of claim 5, wherein the changing the shape of the application window displayed in the first region includes changing the application window displayed in the first region to a portrait mode from a landscape mode based on the determined orientation of the mobile terminal; and changing the application window displayed on the first region to the landscape mode from the portrait mode based on the determined orientation of the mobile terminal. ### Claim 7 (depends on 1) The method of claim 1, wherein the receiving a command to display another application window on the external display includes at least one of detecting a selection of a button provided to the mobile terminal, or detecting a prescribed pattern of motion based on sensed motion of the mobile terminal. ### Claim 8 (depends on 1) The method of claim 1, wherein the application window displayed in the second region is updated in real time irrespective of whether an application associated with the application window displayed in the second region is displayed on the mobile terminal. ### Claim 9 A method of controlling a mobile terminal, comprising: establishing a connection to an external display; displaying a first application window associated with a first application on a display on the mobile terminal; displaying an image of the first application window on the external display; receiving a request to display a second application on the mobile terminal; displaying a second application window associated with the second application on the display on the mobile terminal in response to the request; and displaying an image of the second application window and the image of the first screen on the external display, wherein the second application window associated with the second application replaces the first application window associated the first application on the display of the mobile terminal. ### Claim 10 (depends on 9) The method of claim 9, wherein the image of the first application window is moved from a first region on the external display to a second region on the external display, and the image of the second application window is displayed in the first region on the external display. ### Claim 11 (depends on 10) The method of claim 10, wherein the first region includes a full screen image of the first application window and the second region is an overlay window displayed over the first region. ### Claim 12 (depends on 10) The method of claim 10, wherein the first region and the second region do not overlap each other on the external display. ### Claim 13 (depends on 10) The method of claim 10, wherein the request to display the second application on the mobile terminal is based on a selection of a prescribed button on a body or display of the mobile terminal. ### Claim 14 (depends on 10) The method of claim 10, wherein at least one of a position, size, or orientation of the first and second application window is changed based on an input at the mobile terminal. ### Claim 15 (depends on 10) The method of claim 10, further comprising the steps of: detecting a selection of a prescribed button on a body of the mobile terminal; removing the image of the second application window of the second application from the first region; detecting a second selection of the prescribed button; and displaying the image of the second application window of the second application on the first region. ### Claim 16 (depends on 15) The method of claim 15, wherein when the image of the second application window of the second application is removed by the selection of the prescribed button, the display of the second application window of the second application is maintained on a display of the mobile terminal. ### Claim 17 (depends on 10) The method of claim 10, further comprising the steps of: detecting a change in an inclination of the mobile terminal; and changing a position of the second region within the first region to correspond to the detected change in inclination. ### Claim 18 (depends on 10) The method of claim 10, further comprising the steps of: detecting a change in an inclination of the mobile terminal; and switching positions of the first and second regions between each other based on the detected change in inclination. ### Claim 19 (depends on 18) The method of claim 18, wherein the changing the position of the first and second regions includes detecting a selection of a prescribed button on the mobile terminal. ### Claim 20 A method of controlling a mobile terminal, comprising the steps of: establishing a data connection to a first external device having a display; executing a first application in the mobile terminal; transmitting information associated with the first application to the first external device; displaying a first application window for the first application in a first region of the display; receiving information associated with a second application that executes in a second external device; and displaying a second application window for the second application in a second region of the display based on the information associated with the second application.
