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

A mobile terminal, comprising:

• a display including an illumination;
• a touch sensor overlapped with the display and configured to detect a touch input;
• and
• a controller configured to:
• detect a first tap input applied on the touch sensor in a turn-off state of the illumination of the display and the touch sensor being periodically driven with a second period,
• determine a region of the display that corresponds to the first tap input,
• detect a second tap input applied on the touch sensor in the turn-off state of the illumination of the display within a predefined time period from the first tap input,
• determine if the second tap input is applied within the region,
• if the second tap input is applied within the region and within the predefined time period from the first tap input, switch to turn on the illumination of the display and periodically drive the touch sensor with a first period shorter than the second period, and
• if the second tap input is applied to a spot outside the region, maintain the turn-off state of the illumination of the display and periodically drive the touch sensor with the second period.

A mobile terminal, comprising:

• a display including an illumination;
• a touch sensor overlapped with the display and configured to detect a touch input;
• and
• a controller configured to control one or more functions executable in the mobile terminal when a tap corresponding to a pre-set scheme is applied to the display,
• wherein operation modes of the mobile terminal include:
• an active mode in which the display is activated and the touch sensor is periodically driven with a first period;
• a doze mode in which the display is deactivated and the touch sensor is periodically driven with a second period greater than the first period, the doze mode being set to recognize the tap corresponding to the pre-set scheme;
• and
• a sleep mode in which the touch sensor is in a sleep mode and the display is deactivated,
• wherein the controller is further configured to:
• detect a first tap input applied on the touch sensor in the doze mode,
• 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,
• if the second tap input is applied within the region and within the predefined time period from the first tap input, switch from the doze mode to the active mode, and
• if the second tap input is applied to a spot outside the region of the display that corresponds to the first tap input, maintain the deactivation of the display.

A mobile terminal, comprising:

• a display;
• a touch sensor overlapped with the display and configured to detect a touch input;
• and
• a controller configured to:
• detect a first tap input applied on the touch sensor in state of a deactivated display and the touch sensor being periodically driven with a second period,
• 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,
• if the second tap input is applied within the region and within the predefined time period from the first tap input, activate the display and periodically drive the touch sensor with a first period shorter than the second period, and
• if the second tap input is applied to a spot outside the region of the display that corresponds to the first tap input, maintain the deactivation of the display,
• wherein the controller is further configured to:
• display a home screen on the activated display, the home screen including at least one icon and an empty space,
• detect a third tap input applied to the empty space of the home screen in which the touch sensor is periodically driven with the first period,
• determine a region of the empty space of the home screen that corresponds to the third tap input,
• detect a fourth tap input applied on the empty space of the home screen within a predefined time period from the third tap input,
• determine if the fourth tap input is applied within the region of the empty space of the home screen, and
• if the fourth tap input is applied on the region of the empty space of the home screen within the predefined time period from the third tap input, deactivate the display.
