The present invention relates to a digitizer and, more specifically, to a 3D hovering digitizer controlling an image shape display by sensing information of a triaxial magnetic field depending on a movement of a magnetic pen. According to one aspect of the present invention, the 3D hovering digitizer comprises: a magnetic pen spaced apart from an upper portion of the touch screen to be able to move, while generating a magnetic field therearound; a sensor arranged on an external surface of the touch screen to sense information on a triaxial magnetic field depending on a movement of the magnetic pen; and a control unit receiving the sensed triaxial magnetic field information to control a shape display of a 3D image displayed on the touch screen. According to the present invention, a panel for an additional digitizer is unnecessary, and thus a display device can be produced slimmer and lighter. |
