Abstract

A method comprises during a frame period finding a first EFT noise influenced sensor of a touch screen panel, determining whether the first EFT noise influenced sensor is located at a last transmitting/driving line of the touch screen panel, designating the frame period as a noise influenced frame period using an absolute value threshold if the first EFT noise influenced sensor is not located at the last transmitting/driving line and designating the frame period as the noise influenced frame period using a percentage threshold if the first EFT noise influenced sensor is located at the last transmitting/driving line.
