ＧeoBox 3D processor includes two catagories. One is for 3D format conversion from medical 3D system with side by side output for conventional 3D display devices or converts 3D signal into 120 Hz frame sequential output format for active 3D display. Another is for passive 3D display, including 3D decoding for RH/LH eye frames and executing geometry alignment to stack RH/LH eye projector images together. It can also implement edge blending to build big 3D system with 4x projectors.
There are two passive 3D glasses system. One is polaried filter and glasses. Another system is band-pass spectrum filter and glasses system. Polarized 3D system needs to use silver coating screen and spetrum filter system can use any screen. This is the major difference.
