We proposed a layered capacitance 3D touch screen to detect the object (finger) at three dimensions (3D) range. In the proposed 3D touch screen, the plane-type capacitance sensors and the parallel-type capacitance sensors are layered. The plane-type capacitance sensor detects the object and position at non-contact (proximity range), and identifies the material on contact. The parallel-type capacitance sensor detects the indentation and precise position of the object on contact. In this paper, the 3D touch screen is set on the display and detects the object and position before and after contact. The proposed 3D touch screen may be the functional and useful interface.
