Abstract: A mobile terminal including a communication unit configured to communicate with at least one external terminal; a memory configure to store at least first and second operating systems including at least first and second modes, respectively; and a controller configured to execute the first operating system and to activate the first mode corresponding to the first operating system, to display a first information screen on a display unit corresponding to the activated first mode, to receive a switching signal indicating the first mode is to be switched to the second mode, to activate the second mode and deactivate the first mode, and to display a second information screen on the display unit corresponding to the second mode and that is different than the first information screen.

Abstract: A mobile terminal including a communication unit configured to communicate with at least one external terminal; a memory configured to store at least a first and second operating system including at least first and second modes, respectively; and a controller configured to execute the first operating system and to activate the first mode corresponding to the first operating system, to display a first information screen on a display unit corresponding to the activated first mode, to receive a switching signal indicating the first mode is to be switched to the second mode, to perform an authentication procedure for authenticating that the first mode can be switched to the second mode, to activate the second mode and deactivate the first mode when the authentication procedure is validly performed, and to display a second information screen on the display unit corresponding to the second mode and that is different than the first information screen.

Abstract: A mobile terminal including a communication unit configured to communicate with at least one external terminal; a memory configured to store at least first and second operating systems including at least first and second modes, respectively; and a controller configured to execute the first operating system, to activate the first mode, to control a display unit of the mobile terminal to display a mode configuration screen including selectable options for designating a designated mode corresponding to at least one of the first and second modes to a particular information, and to selectively restrict assigning the particular information from the designated mode to a non-designated mode.

Abstract: A mobile terminal including a communication unit configured to communicate with at least one external terminal; a memory configured to store at least first and second operating systems including at least first and second modes, respectively; and a controller configured to execute the first operating system and to activate the first mode corresponding to the first operating system, to display a first information screen on a display unit corresponding to the activated first mode, to receive a switching signal indicating the first mode is to be switched to the second mode, to attempt to switch to the second mode based on the received switching signal, and to restrict a specific application executing in the first mode when the second mode is not switched to.
