A touch screen is disclosed. A plurality of common electrodes can be configured to operate as display circuitry during a display phase, and to operate as touch sensing circuitry during a touch sensing phase. The plurality of common electrodes can include a first common electrode associated with a first display pixel, and a second common electrode associated with a second display pixel. Circuitry can be configured to update the first display pixel at a first time while driving the first common electrode but not the second common electrode, and update the second display pixel at a second time, after the first time, while driving the second common electrode but not the first common electrode. In some examples, the circuitry can be configured to leave the second common electrode floating while driving the first common electrode, and leave the first common electrode floating while driving the second common electrode. |
