Claim 12:
13. Enacted on a display device comprising a pixel-shifting device including a refractive optic and a piezoelectric actuation system, a method of displaying an image comprising a plurality of image subframes that are displayed in a time-sequential manner, the method comprising
displaying a first image subframe with a first voltage applied to a piezoelectric element coupled to an outer frame of the pixel-shifting device; and
displaying a second image subframe with a second voltage applied to the piezoelectric element of the pixel-shifting device, the second voltage being different than the first voltage, to rotate the refractive optic relative to the outer frame by transmitting movement of the outer frame caused by the piezoelectric element to an inner frame via a curved transmission and thereby shift pixel positions in the second image subframe from corresponding pixel positions in the first image subframe by a fraction of a pixel.
