Abstract: A touch screen device and method for displaying and selecting menus thereof are provided. The touch screen device includes a screen with a display for displaying menu images thereon and a detector for detecting a touch on a screen, and a controller which displays one or more menu bars on the screen. Each of the menu bars may have an expanded portion at one end thereof, and the menu bars may be displayed such that the expanded portions are arranged in a zigzag pattern to facilitate menu selection and reduce input errors. When two or more menu bars are erroneously touched, the controller may enlarge and display the touched menus so that a new touch input for the correct menu can be easily made. Thus, menus displayed on the touch screen may be arranged for easy selection, and input errors may be easily corrected.
