Examples are described for touch-sensitive displays in which ground references for associated electronics are isolated from one another. In one example, a touch-sensitive display includes a display panel, and a touch sensor, the touch sensor including a receive electrode, the touch sensor including a transmit electrode, the receive electrode and the transmit electrode overlaying the display panel, and wherein a ground reference of the receive and/or the transmit electrode is isolated from a ground reference of the display panel, thereby creating a transmission-inhibiting communication boundary between the display panel and the touch sensor, the touch sensor communicatively connected to the display panel so as to exchange data between ground domains separated by the boundary.
