CONTROL CIRCUIT OF TOUCH SCREEN AND NOISE REMOVING METHOD

摘要

The present invention discloses a control circuit of a touch screen and a noise removing method. The present invention provides a technique for performing differential sensing on two adjacent detection lines of a touch screen panel and integrating a differential sensing signal to filter noise. The control circuit and the noise removing method may remove display noise having an effect on two adjacent detection lines, three-wavelength lamp noise having a predetermined frequency, 60 Hz noise, and charger noise caused by battery charging.
