Abstract
A touch sensing apparatus includes a coordinate calculator configured to count a current number of touches and calculate an estimated number of touches, by the unit of touch group, by using touch data including touch coordinates of a plurality of touch electrodes, and detect a discontinuous touch corresponding to a touch group in which the current number of touches and the estimated number of touches are not the same; and a touch data generator configured to generate the touch data including corrected coordinate data.
