Difference Between the Passive Plastic Glasses With Polarized Lenses Used at
the Movies and The Active Shutter System Glasses Used with 3D TVs
With active shutter glasses, crosstalk is eliminated easier than passive
glasses.
Crosstalk is a phenomenon where an image intended for one eye is seen by
the other, causing ghost images to appear.
With the active shutter glasses, both eyes can be closed off for a split
second between each frame. This reduces ghosting or crosstalk.
Passive glasses are used with TVs where a polarized filter in the TV has to
switch directions for each eye.
