Abstract
A display device including a touch panel integrally formed with a display panel such as a liquid crystal display panel is advantageously used in a car navigation system. A ball is displayed together with other information on the display panel. The ball is adapted to be rotated by touching it for scrolling the displayed information or moving a highlighted item on a displayed list. When a desired item is highlighted, that item can be selected by simply pushing the ball to thereby input a command corresponding to the selected item to the system. A navigation map displayed on the display panel may be scrolled or its scale may be changed by rotating the ball. In this manner, a driver can easily and conveniently input a command to the system.
