ABSTRACT:
A display device for sequentially displaying multiple sets of image pixels formed on a transparent mosaic through an aperture pattern formed in a substantially opaque mask. An AC gear motor and drive assembly is employed to move the mosaic through a predetermined travel path relative to the mask to sequentially register the image sets with the aperture pattern. A control system is employed to temporarily deactivate the gear motor at predetermined precise positions to display the various images through the aperture pattern.
