Abstract: A touch sensing apparatus is provided. A touch sensing apparatus comprises a panel comprising a plurality of driving electrodes and a plurality of sensing electrodes crossing the driving electrodes, a driving circuit unit simultaneously applying the driving signals to the driving electrodes in a certain interval and a sensing circuit unit sensing a change in capacitance occurring in intersecting points between the driving electrodes having the driving signals applied thereto and the sensing electrodes, wherein, when a driving waveform of the driving signal applied to the driving electrode in a (2k−1)-th interval and a (2k+1)-th interval (k is a natural number greater than 1) of the certain interval is in the same phase, the driving circuit unit applies a reverse driving signal of the driving waveform of the driving signal of the (2k−1)-th interval to the driving electrode in a 2k interval.
