Beschreibung
Zusammenfassung:	A signal processing circuit of a touch screen according to an embodiment of the present invention comprises multiple driving lines and sensing lines provided to cross each other on the touch screen panel; multiple sensing channels which are connected to each of the sensing lines and detect a touch by sensing the mutual capacitance on nodes on which the sensing lines and driving lines cross each other; distortion detectors detecting distortion by noise from a power voltage of the sensing channels; and a control unit which connects capacitors formed in each of the sensing channels in parallel to each other and operates the signal processing circuit into a distortion mode in case distortion by noise is considered to exist by the distortion detector.
