Mobile terminal performing a different operation based on a type of a tap applied to a display and control method thereof

Abstract

A mobile terminal including a display; a touch sensor configured to detect a touch input on the display; and a controller configured to activate the display and periodically drive the touch sensor with a first period; deactivate the display in response to a predetermined condition and periodically drive the touch sensor with a second period greater than the first period; detect a first tap input applied on the touch sensor in state of the deactivated display; determine a region of the display that corresponds to the first tap input; detect a second tap input applied on the touch sensor in state of the deactivated display within a predefined time period from the first tap input; determine if the second tap input is applied within the region; in response to the second tap input being applied within the region of the display that corresponds to the first tap input, activate the display and periodically drive the touch sensor with the first period; and in response to the second tap input being applied to a spot outside the region of the display that corresponds to the first tap input, maintain the deactivation of the display and periodically drive the touch sensor with the second period.
