Both monitor-style and HoloVizio large-scale systems introduce a fundamentally new comprehensive approach to the field of 3D displaying. Since HoloVizio is not a stereoscopic or multi-view system it lacks most of the backlogs and drawbacks currently associated with 3D displays. HoloVizio is not a purely holographic system that handles an enormous amount of redundant information. It is rather based on holographic geometrical principles with special focus on reconstructing the key elements of spatial vision. The pixels, or rather voxels of the holographic screen emit light beams of different intensity and colour to the various directions. A light-emitting surface composed of these voxels will act as a digital window or hologram and will be able to show 3D scenes undoubtedly being 3D.
