Patent Images
1. A mobile terminal, comprising:
- a display;
a sensor;
at least one module to perform a particular function; and
a controller configured to;
maintain a screen brightness of the display at a lowest level when the mobile terminal is in a sleep state or a lock mode;
maintain the at least one module to be in a non-activated state when the mobile terminal is in the sleep state or the lock mode;
initiate an activation of the at least one module from the non-activated state in response to receiving a particular control command;
increase the screen brightness of the display to a reduced level in response to receiving the particular control command; and
maintain the screen brightness of the display at the reduced level of screen brightness during the activation of the at least one module.

Abstract
A method, system, and device for controlling screen brightness of a mobile terminal are disclosed. In one embodiment, a mobile terminal comprises a display unit, a sensing unit, and a controller configured to maintain a brightness of the display unit at a reduced level of screen brightness during a non-active state of the mobile terminal, and restore the brightness of the display unit to a normal level of screen brightness after a short timeout subsequent to a detection of an event configured to activate the mobile terminal via the sensing unit.
