Abstract
Disclosed is a method for controlling a backlight of a portable terminal, which includes the steps of storing preset backlight brightness values so as to correspond to the backlight brightness values to backlight steps, detecting a backlight brightness value stored so as to correspond to the backlight step required by a user in backlight regulation mode, and regulating the backlight brightness according to the detected backlight brightness value. Further, since the present invention can regulate the backlight brightness at night, the illumination intensity of which is low, the consumption of the battery can be reduced.

A method for controlling brightness of a touch display unit of a portable terminal, the method comprising:
- displaying on the touch display unit a brightness step selection screen for selecting one of a plurality of selectable brightness steps, the plurality of selectable brightness steps corresponding to incremental levels of brightness of the touch display unit;
- while continuing to display the brightness step selection screen, receiving a single selection user input to select a brightness step among the plurality of selectable brightness steps;
- while continuing to display the brightness step selection screen and in direct response to the receiving of the single selection user input of one of the plurality of selectable brightness steps, visually distinguishing the selected brightness step among the plurality of selectable brightness steps on the brightness step selection screen;
- and
- while continuing to display the brightness step selection screen and in direct response to the receiving of the single selection user input of one of the plurality of selectable brightness steps, regulating the brightness of the touch display unit to correspond to the selected brightness step,
- wherein the visually distinguishing of the selected brightness step and the regulating of the brightness of the touch display unit at least partly occur at the same time, and
- wherein the regulating of the brightness of the touch display unit according to the selected brightness step comprises, when there is at least one intervening brightness step between a previously selected brightness step and the selected brightness step, regulating the brightness of the touch display unit from the previously selected brightness step to the selected brightness step without incrementing through the at least one intervening brightness step.
