Active 3D shutter glasses are small LCD screens that alternately dim each side and use an infrared signal with the TV that tells the pair of glasses when to dim each side. “Passive” 3D Glasses are polarized create the illusion of depth by blocking different kinds of light from each eye. Your brain will perceive a 1080p image when it puts the images from each eye together.
