Abstract
A touch apparatus according to an exemplary embodiment includes: a touch panel that includes a plurality of first touch electrodes extending in a first direction and arranged in a second direction that crosses the first direction, and a plurality of second touch electrodes extending in the second direction and arranged in the first direction; and a touch driver that applies a first driving signal for generation of a resonance signal of a stylus pen to the touch panel in a first section, and receives a detection signal from the touch panel in a second section that is next to the first section, wherein the touch driver applies a driving signal of which a ratio of a disable level section with respect to an enable level section within one iterative period is different from that of the first driving signal in the second section, to the touch panel.
