Claim 4:
5. 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,
wherein the demultiplexing circuit comprises:
first switches located between the main scan signal transmission lines and the first sub-scan signal transmission lines, configured to turn on when a first control signal is activated, and configured to turn off when the first control signal is deactivated; and
second switches located between the main scan signal transmission lines and the second sub-scan signal transmission lines, configured to turn on when a second control signal is activated, and configured to turn off when the second control signal is deactivated,

one frame includes first to n-th sub-frames sequentially implemented, and
wherein each of the first to n-th sub-frames includes a first period and a second period following the first period,
where n is an integer greater than or equal to 3,
wherein the demultiplexing circuit is configured to connect the main scan signal transmission lines to the first sub-scan signal transmission lines during the first period, and
wherein the demultiplexing circuit is configured to connect the main scan signal transmission lines to the second sub-scan signal transmission lines during the second period.
