Abstract: Provided is a digitizer with high accuracy of identifying a position, and more particularly, to a digitizer with high accuracy of identifying a position, in which a plurality of magnetic force sensors are installed to collect a plurality of pieces of position information regarding a magnetic force pen and a position of the magnetic force pen is determined by using only position information selected according to a specific reference. Since only information with high reliability, among pieces of position information of the magnetic force pen measured by the plurality of magnetic force sensors, is used, accuracy of identifying a position of the magnetic force pen may be increased.

Abstract: 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.

Abstract: Provided is a touch screen integrated digitizer including a three-axis magnetic force sensor and a magnetic pen, which measures a distribution and a change amount of a magnetic force vector, generated by moving the magnetic pen generating a magnetic force, to accurately sense a position of the magnetic pen which is moved on a touch screen. Since the digitizer for detecting position information of an external input unit is implemented with a magnetic force sensor installed at an internal edge of a display device, a separate digitizer panel is not provided, and thus, the display device is lightened and slimmed.
