A touch sensing apparatus includes an approach sensing electrode unit including a plurality of first approach sensing electrode arrays disposed on a substrate and a plurality of second approach sensing arrays disposed adjacent to the first approach sensing electrode arrays, a voltage supply unit to supply a voltage to any of the first approach sensing electrode arrays and the second approach sensing electrode arrays, a signal generation unit to generate an approach sensing signal by detecting a variation of capacitance generated between the first approach sensing electrode arrays and the second approach sensing electrode arrays, the variation of capacitance occurring in a 3-dimensional (3D) approach sensing region, and an information generation unit to generate contact information corresponding to the approach sensing signal generated by the signal generation unit.
