Abstract
An advertising display apparatus with precise rotary drive includes a programmable stepper motor positively coupled to a pair of eccentric drives. Rotation of the eccentric drives moves a film sheet containing discrete images formed from corresponding sets of pixels through a closed loop path across a platen stopping at precise dwell points. At each dwell point, a set of pixels register with a plurality of apertures within an overlying grid sheet and are illuminated by a light source within the apparatus to display the image.
