  • Publication number: 20100131880
    Abstract: According to an embodiment, a terminal and a method of displaying menu icons thereof are discussed, by which a terminal user is facilitated to input various commands. An embodiment of the present invention includes a touch screen and a control unit configured to control at least one touch-available icon to move between outer and inner areas of an image displayed on the touch screen in a direction of a touch-drag on the touch screen. Accordingly, the electric current for detecting a touch is supplied to the touch screen only if the touch-available icon is displayed on the touch screen. Hence, the present invention minimizes power consumption in using the touch screen.
