Zusammenfassung:	Systems and methods are provided for improving displayed image quality of an electronic display with reduced power consumption. In some embodiments, a display pixel in the electronic display includes a pixel electrode and a common electrode. A pixel electrode driver electrically coupled to the first display pixel writes the display pixel by supplying a pixel voltage signal to the pixel electrode. A common electrode driver electrically coupled to the common electrode includes a power amplifier that supplies a common voltage signal to the common electrode to predictively offset net charge accumulation expected in the common electrode; a first power supply rail selectively connectable to the power amplifier based on a target voltage of the common voltage signal; and a second power supply rail selectively connectable to the power amplifier based on the target voltage, in which the first and second power supply rails supply different voltages when connected.
