1. A method of displaying an image on a display, the display including display elements arranged in an array having a first direction and a second direction that intersects the first direction, the method comprising:

  • writing image data to the array of display elements; and

    maintaining a current position of each display element of the array of display elements, wherein maintaining a current position includes alternating the polarity of a first voltage signal along the first direction in a first pattern having a first frequency spectrum, and alternating the polarity of a second voltage signal along the second direction in a second pattern having a second frequency spectrum, wherein at least one of the first and second frequency spectrums includes a plurality of frequency components, and wherein the first frequency spectrum corresponds to a pattern of polarities of voltage signals applied to rows of display elements, and wherein the second frequency spectrum corresponds to a pattern of polarities of voltage signals applied to columns of display elements.
