PURPOSE: A 4D display system for enabling a user to touch and input a 3D image is provided to arrange rod sensors whose lengths are proper for input on a 2D panel, thereby inputting and displaying 3D information. CONSTITUTION: An input device reads information sensed by a rod sensor as 3D information by arraigning rod sensors on a 2D panel. The lengths of the rod sensors are proper for input. An output device system outputs the 3D information by arranging the rod sensors on the 2D panel.
