Abstract
An exemplary embodiment of the present invention provides a touch apparatus including: a touch panel configured to include a plurality of touch electrodes; a touch driver configured to apply a first driving signal to a first touch electrode of the touch electrodes during a first period, and a second driving signal to the touch electrodes during a second period subsequent to the first period; and a touch controller configured to determine a detection signal as a valid touch signal based on whether a signal strength of the detection signal received in response to the first driving signal exceeds a first threshold during the first period, wherein the detection signal include at least one of a first detection signal generated by a first touch object and a second detection signal generated by a second touch object, and the first detection signal is determined as a valid touch signal, while the first threshold is set to filter the second detection signal.
