Abstract
The refresh rate of an LCD panel is changed as the brightness of the LCD panel changes. When the brightness of the LCD panel is decreased, the refresh rate is also decreased. In addition, whether the power source of the apparatus is AC or DC is determined based on whether an AC adapter is attached or not. When the DC power source is used, the brightness and refresh rate of the LCD panel is lowered with respect to when the AC power source is used.
