3D signal shall be decoded into RH/LH output signals for two projectors. The images from two projectors should be stacked together. User needs to use silver coating screen and polarized filters are required for each eye. 3D glasses needs to match the type of the filters. User can also use spectrum filter system to get 3D effect with conventional screen. The cost for spectrum filter and glasses will be higher than polarized system. G602 can decode 3D signal and execute precise image stacking to perform the most comfortable 3D effect.
