Abstract
An embodiment of the present disclosure provides a touch apparatus including: a touch sensor; and a touch controller operating in a full driving mode for applying a first driving signal for generating a resonance signal of a stylus pen to the touch sensor and a skip driving mode in which a second driving signal having a period having an off-duty different from that of the first driving signal is applied to the touch sensor, and obtaining touch coordinate information from a detection signal received from the touch sensor.
