First Claim
Patent Images
1. A mobile terminal, comprising:
- a display;
a sensor configured to sense an event when the display is in a sleep state, wherein a brightness of the display in the sleep state is at a lowest level; and
a controller configured to;
activate the display;
increase the brightness of the display to a reduced level to display screen information of the event;
maintain the brightness of the display at the reduced level of screen brightness during a short timeout subsequent; and
increase the brightness of the display to a normal level in response to a control command during the short timeout subsequent, wherein the controller is configured to decrease the brightness of the display to the lowest level when a control command is not received during the short timeout subsequent.

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.

12. A method of a mobile terminal, the method comprising:
-
maintaining a brightness of a display of the mobile terminal at a reduced level of screen brightness during a non-active state of the mobile terminal; starting a timer for a short timeout in response to a detection of an event, wherein the brightness of the display of the mobile terminal is controlled to be at a lower level of screen brightness than a normal level of screen brightness during the short timeout; and setting the brightness of the display to the normal level of screen brightness upon completion of the short timeout if the event is configured to place the mobile terminal in an active state, or restoring the brightness of the display to the reduced level of screen brightness if the event is configured to place the mobile terminal in the non-active state. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
