Mobile terminal and method for controlling the same

A mobile terminal, comprising:

• a main body;
• a display disposed on the main body;
• a receiver disposed on the main body and located adjacent to the display;
• an infrared unit disposed on the main body at a first distance from the receiver in a first direction and configured to output infrared rays;
• an iris recognition sensor disposed on the main body at a second distance from the receiver in a second direction opposite the first direction and configured to receive infrared rays reflected from a subject;
• a low power image sensor disposed on the main body at a third distance from the receiver in the second direction and having a focal point matching a focal point of the iris recognition sensor, wherein the third distance is greater than the second distance;
• and
• a controller configured to:
• detect an occurrence of an event while the display is in an inactive state, wherein when the display is the inactive state, a backlight of the display is off such that visual information is not displayed,
• determine whether or not a face image is detected through the low power image sensor in response to the detection of the occurrence of the event,
• control one area of the display from the inactive state to an active state when the face image is detected, and
• display specific information related to the event on the one area of the display in the active state,
• wherein when the detected face image corresponds to the side face, the specific information is summary information related to the event, and
• wherein when the detected face image corresponds to a front face, the specific information is detail information related to the event.
