    Abstract: A touch panel is provided. The touch panel includes a channel electrode unit configured to include a plurality of first electrodes disposed in a first direction and a plurality of second electrodes disposed in a second direction intersecting with the first direction, and a controlling unit configured to apply a driving signal to the electrodes in the channel electrode unit in a unit of a plurality of electrodes, transmit the driving signal to a resonance circuit of a stylus pen approaching the touch panel through a capacitive coupling, and receive response signals generated from the resonance circuit of the stylus pen from each of the plurality of electrodes to determine a location of the stylus pen including the resonance circuit.
