Mobile terminal and screen control method thereof
First Claim

1. A mobile terminal comprising:
- a display for sensing at least a touch on the display or an approach of a pointing means proximate to a sensed area on the display; and
a controller for controlling brightness of the display at the sensed area according to the touch or the approach of the pointing means, the controller configured to;
apply an illumination only to the sensed area where the approach of the pointing means is sensed while the mobile terminal is in a standby mode in which a display light of the display is turned off, wherein a radius of the illumination is a preset value, and the illumination generates a searchlight effect;
expand the radius of the illumination in proportion to a duration of the pointing means detected at the sensed area, such that a size of the illumination generating the searchlight effect remains smaller than a size of the display; and
reduce the brightness of the display at the sensed area in response to an increase in a distance from the sensed area to the pointing means.

7. A screen control method of a mobile terminal, the screen control method comprising:
-
applying an illumination only to a sensed area of a touch screen of the mobile terminal where an approach of a pointing means is sensed while the mobile terminal is in a standby mode in which a display light of the touch screen is turned off, wherein a radius of the illumination is a preset value, and the illumination generates a searchlight effect; determining a duration during which the pointing means is held proximate to the sensed area; expanding the radius of the sensed area illumination in proportion to the duration during which the pointing means is held, such that a size of the illumination generating the searchlight effect remains smaller than a size of the touch screen; and reducing a brightness of the illumination in response to an increase in a distance from the sensed area to the pointing means. - View Dependent Claims (8, 9, 10, 11, 12, 14, 15, 16, 17)
