MULTI-SCALE DIGITIZER USING 3D MAGNETIC FORCE SENSOR AND MAGNETIC FORCE PEN

摘要

Provided is a multi-scale digitizer using a 3D magnetic force sensor and a magnetic force pen, wherein one or more magnetic force sensors are installed inside a recognition device, and a change in a magnetic field of an external input unit with a magnetic material installed therein is measured through the sensors to detect a position of the external input unit. Since the digitizer capable of detecting position information of an external input unit by using the magnetic force sensors installed inside the recognition device is implemented, there is no need to provide a separate digitizer panel, and thus, a display device may be reduced in weight and thickness.
