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.

Display apparatus with AC gear motor drive control

A display apparatus having a transparent image screen which contains a mosaic of four discrete images formed from pixels which are interwoven in a predetermined arrangement such that each of the images are selected by precise positioning of the screen in four different positions relative to a grid mask which masks out all but pixels of a selected image. A platen comprising a platen surface which is supported by a rib structure mounts the image screen and is moveable through a precise pattern for selecting the pixels, and thereby the image, to be projected. A pair of arms are coupled to the platen and an eccentric drive and are driven by the eccentric drive to advance the platen positively through the pattern.

Advertising display method and apparatus

A drive control and interface apparatus housed within an advertising display for driving a stepper motor coupled to a display device to sequentially display a plurality of images. The drive control and interface apparatus includes a microprocessor having program memory connected to the motor through a motor driver. A drive control program operates the microprocessor to drive the stepper motor to change the image displayed after a corresponding predetermined period of time. The program includes drive routines for fast and slow image changes that drive the stepper motor to minimize resonance. A control interface connects to the microprocessor. The program is responsive to the control interface to permit manual sequencing of the display and user selection of the corresponding display times for each image.
