1. A display system, comprising:
a display panel including a plurality of pixels, each of the plurality of pixels having:
a pixel electrode; and
a common electrode electrically coupled to a common electrode node; and
a digital drive device including a common electrode circuit coupled to the common electrode node, the common electrode circuit being configured to vary the common electrode voltage to maintain a voltage balance across the display panel.
