ABSTRACT:
This invention relates to a method for driving a display panel (DP) having pixels (P). The display panel (DP) is driven with a sequence of image frames. The image frames are converted to a drive signal (V2) comprising refresh frames with a refresh frame period (TR) shorter than the image frame period. A pixel (P) of the display panel (DP) is driven with an adapted drive signal having a first polarity during a first group of refresh frame periods, and having a reversed polarity during a subsequent second group of refresh frame periods. The first group and the second group each comprise at least two refresh frame periods.
