Passive 3D processor
Passive 3D will provide the most comfortable 3D display with less eye fatigue. It is the best 3D system for watching movie for hours and less harm for children. User needs one silver coating screen but the projector can be low cost one without 3D capability. GeoBox can decode 3D signal into RH/LH eyes for two projectors and also align the image in each projector to stack together. User can also use 4 projectors to build bigger 3D system through edge blending technoly from GeoBox. VNS can provide technical support for complete 3D system setup.
