Abstract: Methods and devices useful in discharging an aberrant charge on the VCOM of an electronic display and harvesting energy from the VCOM of the electronic display are provided. By way of example, a method may include supplying an activation signal to an active switching device of an electronic display. The active switching device is configured to discharge an aberrant charge on a common electrode of the electronic display. The method further includes discharging the aberrant charge by way of the active switching device. Discharging the aberrant charge comprises preventing a possible occurrence of image artifacts from becoming apparent on the electronic display.
