Abstract
A touch sensing system includes a pen including a resonant circuit embedded therein, XY electrodes including X electrodes and Y electrodes perpendicular to the X electrodes, an antenna surrounding the XY electrodes, and a first touch driving circuit which transmits a resonant inductive signal to the pen through electric coupling and to receive a resonance signal from the pen through the antenna.
