Abstract
A touch sensing apparatus including: a touch panel including a first electrode and a second electrode; a driver configured to apply a driving signal to the first electrode; a touch sensor configured to receive a signal transferred depending on the driving signal from the second electrode, and to convert and output the signal as a sensing signal; and a touch controller configured to detect the sensing signal. The touch panel further includes a third electrode and a fourth electrode which transfer noise signals having different magnitudes to the touch sensor, and the touch sensor outputs the sensing signal by using a difference in the noise signals and the signal.
