摘要

The device has a lenticular network comprising elementary devices each with an elementary lens and a centered or assimilated optical system. An electronic screen e.g. plasma screen, has pixels each comprising sub-pixels of different colors. Each optical system has identical optical characteristics and possesses a symmetry axis of rotation perpendicular to focal plane of the lens. The pixels of interleaving image are not composed of sub-pixels of same primary image but of different primary images.
