Active Shutter 3D (or Active 3D) works by very quickly alternating pictures displayed on the screen. The glasses control which of the two pictures is seen by alternating between opaque and transparent. This technology is called “Active” because the glasses are powered (using batteries) and they actively control which picture is perceived by which eye. The glasses need to be synchronized perfectly with the television screen and because of this, the glasses are expensive ($20 - $100). Also, active 3D TVs cause some people to become dizzy from to the constant flickering. This method is very similar to the 3D technology used by movie theaters - you can even use glasses from a theater with your passive 3D TV. Instead of displaying one picture at the time like in active 3D, both are shown simultaneously; one with a horizontal light polarization and the other one vertical. The glasses have a different filter for each eye: one that cuts the horizontal light, and the other one the vertical light. The glasses are passive: they are not powered, so they are a lot cheaper than the glasses required for the active shutter technology.
Sorry, there was a problem. Please try again later.Passive 3D the tv does the work and you can use the glasses you get at most movie theaters. With Active 3D you need specific glasses that have to either be charged or powered in some way.
Sorry, there was a problem. Please try again later.Only works with active and you will have to pay $50 a pair of them then try to get them to work. Don't waste you money
Sorry, there was a problem. Please try again later.Passive 3D glasses don't require batteries (they're the same kind that you get at a movie theatre). Active 3D glasses require batteries.
