According to one embodiment of the present invention, a touch screen apparatus includes: a driving circuit unit applying a certain driving signal to N-number, wherein N is a natural number of 2 or larger, of first electrodes among a plurality of first electrodes prepared in a panel unit; a sensing circuit unit detecting capacitance from a plurality of second electrodes prepared in the panel unit and outputting a sensing signal; and a calculation unit determining a touch input according to the sensing signal. The driving circuit unit determines a region of one or more columns, in which the sum of the columns is a maximum value among the columns of an N x M fundamental matrix, selects any one row in which elements having a maximum level in the determined region of the columns are included most, generates a first matrix by reversing the level of the elements of the selected row, and generates the driving signal according to a driving matrix generated according to the first matrix. |
