Abstract: Various embodiments enable driving one or more sub-pixels with a source voltage while concurrently modulating the voltage of one or more common electrodes coupled to the sub-pixels to perform input sensing with the common electrodes. The voltage driven onto the sub-pixel may be shifted while the common electrode is modulated by a value about equal to about the amplitude of the modulation applied to the common electrode. Thus, the potential difference between the source line and common electrode remains substantially unchanged so that display asperities are not introduced while input sensing while concurrently updating a sub-pixel with display information. Thus, the common electrode(s) may be modulated for input sensing without interfering with display updating of the one or more sub-pixels, greatly increasing the amount of time available for performing input sensing and/or display updating.
