The present invention is an improvement in dynamic autostereoscopic visual displays emitting a field of light beams into an observer viewing space from a hogel array formed at a transparent projection screen surface having refractive beam expanding functions. The transparent screen is illuminated from the rear by an X-Y array of projectors focused on the screen, where each hogel location is illuminated by a local group of multiple projectors within the larger array. The brightness, color and direction of the light beams emitted by each hogel are controlled by one image point in each member of the local projector group that illuminates that hogel. The invention enables autostereoscopic display systems with compact dimensions and high overall resolution and brightness by combining the output of an array of small projectors with lower resolution and brightness on a single projection screen.
