A mobile terminal comprising: a terminal body; a microphone sensor configured to sense a sound generated around the terminal body; a touch-sensitive display unit configured to switch between an activated state in which lighting provided inside the display unit to illuminate the display unit is turned on and a deactivated state in which the lighting is turned off; and a controller configured to: sense a plurality of consecutive touch inputs applied to the display unit when the display unit is deactivated; determine whether the sensed touch inputs match a pre-set pattern; when the sensed touch inputs match the pre-set pattern, release a locked state of the mobile terminal, switch the deactivated display unit to the activated state, and selectively display on the activated display unit at least one execution screen among a plurality of pre-set execution screens; characterized in that the controller is further configured to: identify, using a sound generated when the sensed touch inputs are applied to the display unit, a type of an object used to apply the sensed touch inputs; and selectively display on the activated display unit the at least one execution screen among the plurality of pre-set execution screens based on the number of touches included in a final touch input among the sensed touch inputs and the identified type of the object. a terminal body; a microphone sensor configured to sense a sound generated around the terminal body; a touch-sensitive display unit configured to switch between an activated state in which lighting provided inside the display unit to illuminate the display unit is turned on and a deactivated state in which the lighting is turned off; and a controller configured to: sense a plurality of consecutive touch inputs applied to the display unit when the display unit is deactivated; determine whether the sensed touch inputs match a pre-set pattern; when the sensed touch inputs match the pre-set pattern, release a locked state of the mobile terminal, switch the deactivated display unit to the activated state, and selectively display on the activated display unit at least one execution screen among a plurality of pre-set execution screens; characterized in that the controller is further configured to: identify, using a sound generated when the sensed touch inputs are applied to the display unit, a type of an object used to apply the sensed touch inputs; and sense a plurality of consecutive touch inputs applied to the display unit when the display unit is deactivated; determine whether the sensed touch inputs match a pre-set pattern; when the sensed touch inputs match the pre-set pattern, release a locked state of the mobile terminal, switch the deactivated display unit to the activated state, and selectively display on the activated display unit at least one execution screen among a plurality of pre-set execution screens; characterized in that the controller is further configured to: identify, using a sound generated when the sensed touch inputs are applied to the display unit, a type of an object used to apply the sensed touch inputs; and selectively display on the activated display unit the at least one execution screen among the plurality of pre-set execution screens based on the number of touches included in a final touch input among the sensed touch inputs and the identified type of the object.
