Abstract: A touch panel includes odd-numbered touch sensor rows, even-numbered touch sensor rows, odd-numbered sensing signal transmission lines extending respectively connected to the odd-numbered touch sensor rows, and even-numbered sensing signal transmission lines respectively connected to the even-numbered touch sensor rows. First sub-scan signal transmission lines are connected only to the odd-numbered touch sensor rows, and second sub-scan signal transmission lines are connected only to the even-numbered touch sensor rows. Main scan signal transmission lines are connected to a demultiplexing circuit to selectively connect the main scan signal transmission lines to the first sub-scan signal transmission lines or the second sub-scan signal transmission lines.
