configured to display the event information on the display of the at least one external terminal automatically and without user interaction based on the at least one external terminal being a pre-registered external terminal. ### Claim 5 (depends on 1) The mobile terminal of claim 1, wherein the controller is further configured to display the event information on the display of the at least one external terminal when the at least one external terminal has a predetermined intimacy with the mobile terminal over a predetermined referenced value. ### Claim 6 (depends on 5) The mobile terminal of claim 5, wherein the predetermined reference value includes at least one of a number of calls or messages transferred between the at least one external terminal and the mobile terminal, the external mobile terminal being included in a friends list set on the mobile terminal, the external terminal being included in a friends list on a social network, and intimate contents included in the received event signal related to the event. ### Claim 7 (depends on 1) The mobile terminal of claim 1, wherein the event signal is generated by at least one of a call transmission/reception, a message transmission/reception, a data transmission/reception via an instant messaging service, a data transmission/reception via a social networking service and a schedule indication. ### Claim 8 (depends on 1) The mobile terminal of claim 1, wherein the controller is further configured to compare a first designated security level related to at least one of the mobile terminal and information displayed on the first information screen to a second designated security level related said at least one external terminal, and to selectively display contents of the first information screen on the display of the at least one external terminal based on a result of the comparison of the first and second designated security levels. ### Claim 9 (depends on 1) The mobile terminal of claim 1, wherein the controller is further configured to control the at least one external terminal to switch to the first mode when the at least one external is operating in the second mode. ### Claim 10 (depends on 1) The mobile terminal of claim 1, wherein the controller is further configured to receive another event signal indicating an event related to the second mode has occurred on the at least one external terminal, and to selectively display event information related to the event of the second mode on the display of the mobile terminal. ### Claim 11 A method of controlling a mobile terminal, the method comprising: allowing, via a communication unit of the mobile terminal, communication with at least one external terminal; storing, in a memory of the mobile terminal, at least a first and second operating system including at least first and second modes, respectively; executing, via a controller of the mobile terminal, the first operating system and activating the first mode corresponding to the first operating system; displaying, on a display of the mobile terminal, a first information screen corresponding to the activated first mode; receiving, via the controller, an event signal indicating an event related to the second mode has occurred on the mobile terminal; outputting a signal indication information related to the event at the mobile terminal; selectively displaying event information related to the event of the second mode on a display of the at least one external terminal if the at least one external terminal meets a prescribed condition; controlling, via the controller, the at least one external terminal to selectively display contents of the first information screen corresponding to the activated first mode on the display of the external terminal; and when a specific region from the first information screen and a display effect to be applied to the specific region are selected and when an entire part of the first information screen is displayed on the display of the external terminal, displaying the entire part of the first information screen with the selected display effect applied to the specific region on the display of the external terminal, while the selected specific region of the first information screen is displayed without the selected display effect on the display of the mobile terminal, wherein the display effect applied to the specific region comprises at least not displaying the selected specific region, enlarging the selected specific region or shrinking the selected specific region. ### Claim 12 (depends on 11) The method of claim 11, wherein the selectively displaying displays the event information on the display of the at least one external terminal when receiving an input from a user authorizing the display of the event information. ### Claim 13 (depends on 11) The method of claim 11, wherein the selectively displaying displays the event information on the display of the at least one external terminal when the event signal includes information related to the at least one external terminal. ### Claim 14 (depends on 11) The method of claim 11, wherein the selectively displaying displays the event information on the display of the at least one external terminal automatically and without user interaction based on the at least one external terminal being a pre-registered external terminal. ### Claim 15 (depends on 11) The method of claim 11, wherein the selectively displaying displays the event information on the display of the at least one external terminal when the at least one external terminal has a predetermined intimacy with the mobile terminal over a predetermined referenced value. ### Claim 16 (depends on 15) The method of claim 15, wherein the predetermined reference value includes at least one of a number of calls or messages transferred between the at least one external terminal and the mobile terminal, the external mobile terminal being included in a friends list set on the mobile terminal, the external terminal being included in a friends list on a social network, and intimate contents included in the received event signal related to the event. ### Claim 17 (depends on 11) The method of claim 11, wherein the event signal is generated by at least one of a call transmission/reception, a message transmission/reception, a data transmission/reception via an instant messaging service, a data transmission/reception via a social networking service and a schedule indication. ### Claim 18 (depends on 11) The method of claim 11, further comprising: comparing, via the controller, a first designated security level related to at least one of the mobile terminal and information displayed on the first information screen to a second designated security level related said at least one external terminal; and selectively displaying contents of the first information screen on the display of the at least one external terminal based on a result of the comparison of the first and second designated security levels. ### Claim 19 (depends on 11) The method of claim 11, further comprising: receiving another event signal indicating an event related to the second mode has occurred on the at least one external terminal; and selectively displaying event information related to the event of the second mode on the display of the mobile terminal.
