A method for driving a display panel having a variable refresh rate is disclosed. The method comprises receiving a current input frame from an image source. Next, it comprises determining a number of re-scanned frames to insert between the current input frame and a subsequent input frame, wherein the re-scanned frames repeat the input frame, and wherein the number of re-scanned frames depends on the minimum refresh interval (MRI) of the display panel. Further, it comprises calculating respective intervals at which to insert the re-scanned frames between the current input frame and the subsequent input frame. Subsequently, it comprises determining if a charge accumulation in pixels of the display panel has crossed over a predetermined threshold value. Finally, responsive to a determination that the charge accumulation has crossed over a predetermined threshold value, it comprises performing a counter-measure to remediate the charge accumulation.
