Claim 6:
7. A display device, comprising:
an image producing element comprising a plurality of pixels, the image producing element being configured to produce a display image; and
a pixel-shifting device comprising
an outer frame,
an inner frame coupled to the outer frame via a flexure positioned along a side of the inner frame,
a refractive optic mounted to the inner frame, and
a plurality of piezoelectric actuators each coupled to the outer frame and also coupled to the inner frame by a corresponding transmission comprising a curved shape; and

a controller configured to control the plurality of piezoelectric actuators to control an angle of the refractive optic relative to the outer frame by transmitting movement to the inner frame via the corresponding transmission to shift the display image by a fraction of a pixel.
