A touch panel is disclosed. The touch panel is detects a position of a stylus, which includes first and second resonance circuits. The touch panel includes first and second coils respectively extending in first and second directions. Each of the first coils emits a first signal having a first frequency and receives a second signal having a second frequency, where emitting the first signal and receiving the second signal are successively and respectively performed by the plurality of second coils. In addition, each of second coils emits a second signal having the second frequency and receives a first signal having the first frequency, where emitting the second signal and receiving the first signal are successively performed. The first resonance circuit of the stylus generates the first signal after receiving the first signal, and the second resonance circuit of the electromagnetic stylus generates the second signal after receiving the second signal.
