1. An electronic device comprising:
a panel comprising a plurality of first electrodes extending in a Y-axis and a plurality of second electrodes extending in an X-axis;
a driving part configured to individually control a direction of current flowing through the plurality of first electrode and the plurality of second electrodes so as to generate electromagnetic fields, thereby driving a stylus; and
a determination part configured to receive a signal generated in the stylus so as to determine touch coordinates,
wherein each of the plurality of first electrodes and the plurality of second electrodes does not form a closed loop, and
wherein the driving part is configured to control the direction of the current flowing through the first electrode and the second electrode is controlled based on a position of the first electrode or the second electrode around a tip of the stylus to generate the electromagnetic fields.
