Abstract: Provided are an operation mode-driving mechanism and method for a mobile terminal is provided for of rapidly driving specific operation mode. The operation mode-driving method is provided for a mobile terminal including a first body having a first and a second display and a second body having a first and a second keypad, the second body being pivotally coupled with the first body on a longitudinal axis of the mobile terminal. The operation mode-driving method includes determining whether a rotation-based driving function is activated and if the rotation-based driving function is activated, driving an operation mode on the basis of whether the first and second bodies are rotated relative to each other.
