According to the present invention, a touch screen device includes a panel unit, a driving circuit unit, a sensing circuit unit, and a control unit. The control unit: applies a driving signal to a first node capacitor, which is defined at an intersection between a first driving electrode, among a plurality of driving electrodes, and a first sensing electrode, among a plurality of sensing electrodes; and corrects gain of a plurality of converter circuit units so that a voltage level of an output signal of each of the converter circuit units with respect to capacitance of the first node capacitor can be same with a predetermined voltage level. Each of the panel disparity correction units can correct the output signals of the converter circuit units by using capacitance of the first capacitors included in each panel disparity correction unit if the driving signal is applied to the first driving electrode. |
