Abstract
A signal processing circuit of a touch screen panel is provided. A signal processing circuit can include a plurality of driving lines and sensing lines intersecting on the touch screen panel, a plurality of sensing channels connected to the sensing lines respectively and configured to detect whether a touch is performed by sensing mutual capacitance on intersecting nodes of the driving lines and the sensing lines, a distortion detection unit configured to detect whether distortion due to noise occurs on the basis of output voltages of the sensing channels, and a control unit configured to operate switches to alternate the circuit between a distortion mode and a normal mode, depending on whether noise is detected.
