Abstract
During of some last years our company investigates and produces 3D autostereoscopic displays of the different sizes. The multi-view 3D display from our company consists of the ordinary flat TFT LCD or plasma display in front of which the special optical filter is situated. In this paper we describe our last achievements for the creation of the large 3D systems, consisting of a set of identical display panels. In particular, we consider here a construction of the autostereoscopic back projection system. In this case a situation is more complicated, because colour value of every R G, and B subpixel is projected on the same place that leads to the decrease of the 3D resolution and quality of the observed stereo-image. The other problem is the adjustment of the 3D large system, so the special approaches are discussed. The corresponding equations for the calculation of the stereo-image for the projection wall will be presented. We demonstrate also that for the same structure of the optical filter the different number of views may be used. Based on the presented principles and approaches our company creates the first in the world 3D large projection system. The future directions of development of the 3D large display are also discussed.
