DIGITIZER AND METHOD FOR REDUCING DETECTING POSITION ERROR

摘要

According to an embodiment of the present invention, provided is a digitizer which includes: a plurality of magnetic force sensors which detect a magnetic force vector for the distribution of a magnetic force which is generated at a magnetic force pen; and a control unit finally selecting three magnetic force sensors which form a triangle of which the biggest interior angle is less than or equal to 120, among the plurality of magnetic force sensors; and an image panel unit displaying a position of the magnetic force pen, which is calculated by triangulation, based on the magnetic force vector measured from the three magnetic force sensors selected by the control unit.
