Abstract:
A touch apparatus according to an exemplary embodiment of the present invention includes: a touch sensor; and a touch controller that operates in a resonance driving mode during which a first driving signal is output for generation of a resonance signal of a stylus pen to the touch sensor and an idle mode during which the driving signal output to the touch sensor is stopped, and obtains first touch coordinate information from a detection signal input from the touch sensor during the resonance driving mode.
