Abstract
A touchscreen device may include: a panel unit, a driving circuit unit, a sensing circuit unit and a control unit. The control unit may apply a driving signal to a first node capacitor formed at an intersection between a first and a first one of the plurality of sensing electrodes and calibrate gains of the plurality of converter circuit units. Each of the plurality of panel deviation calibration units may calibrate an output signal from the respective one of the plurality of converter circuit units by using a capacitance value of a first capacitor included in the respective one of the plurality of panel deviation calibration units when a driving signal is applied to the first one of the driving electrodes.
