The present invention is directed to a method of driving an in-cell touch screen. In one embodiment, adjacent common voltage (VCOM) electrodes, a source line and/or a gate line is set high-impedance, such that an equivalent capacitor is not possessed by the current VCOM electrode. In another embodiment, a gate line is set high-impedance in the touch sensing mode. A voltage waveform of the current VCOM electrode is applied to adjacent VCOM electrodes abutting the current VCOM electrode and/or to a source line, such that an equivalent capacitor has no effect on the current VCOM electrode.


A driver integrated circuit (IC) (102) is arranged to selectively operate in a display mode and a touch-sensing mode when the driver IC (102) is coupled to a touch display panel (101).
