摘要： Touch screen systems and method of compensating noise in same are presented. One touch screen system includes; a touch screen panel having sense channels providing a sense output corresponding to a capacitance variation associated with an applied touch input as detected by one or more sensing units connected to the sense channels. A parasitic capacitance is accumulated in the sense channels as the touch input is applied. The touch screen system also includes a touch controller receiving the sense output and including; a noise compensation block configured to generate a compensation capacitance to compensate for the parasitic capacitance and provide a compensation output, and a signal conversion unit that receives the sense output and the compensation output and generates a noise compensated sense output.
