Claim 6:
7. A touch panel comprising:
odd-numbered touch sensor rows corresponding to odd-numbered rows;
even-numbered touch sensor rows corresponding to even-numbered rows;
odd-numbered sensing signal transmission lines extending in a row direction, arranged side by side in a column direction, and respectively connected to the odd-numbered touch sensor rows;
even-numbered sensing signal transmission lines extending in the row direction, arranged side by side in the column direction, and respectively connected to the even-numbered touch sensor rows;
first sub-scan signal transmission lines extending in the column direction, arranged side by side in the row direction, and connected only to the odd-numbered touch sensor rows;
second sub-scan signal transmission lines extending in the column direction, arranged side by side in the row direction, and connected only to the even-numbered touch sensor rows;
main scan signal transmission lines extending in the column direction and arranged side by side in the row direction; and
a demultiplexing circuit configured 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,
a scan signal transmission circuit connected to the main scan signal transmission lines and configured to sequentially transmit scan signals to the main scan signal transmission lines;
a sensing signal receiving circuit connected to the odd-numbered sensing signal transmission lines and the even-numbered sensing signal transmission lines and configured to receive sensing signals corresponding to the scan signals from the odd-numbered sensing signal transmission lines and the even-numbered sensing signal transmission lines; and
a control circuit configured to detect a touch position based on the sensing signals and configured to control the scan signal transmission circuit, the sensing signal receiving circuit, and the demultiplexing circuit.
