Question about 3D TV Glasses

[RacecarBMW]

Can someone explain to me the different types of 3D glasses used on current 3D tvs.

I thought all of them were the active shutter type but then I was in Bestbuy and I saw an LG that uses the polarized version used in movie theatres.

I wish there was some sort of standard, can the PS3's 3D feature work with both of these types of T.Vs

Thank you for your help. Also can someone tell me how the active shutter work I mean I can't tell that there is a shutter or anything changing.

There are the active type of glasses which has the shutters, and are more expensive. But you will get true HD, with this type, and the tv's tend to be cheaper as they don't have to do as much work, because it's the glasses doing the hard work.

Then there are the passive type, which are similar as to what you will find in the cinema. T.v's tend to be more expensive, and you don't get 'true' HD as the lens blocks out some of the picture, but your brain will fill in the gaps to a certain extent.

They work, on the principle of you alternating blinking between your right and left eye very quickly. So instead of you doing the blinking, the glasses do it. Again the brain attempts to fill the gaps in and a 3D image is produced.

As far as your PS3 is concerned, 3D is 3D, passive or active.

A friend has 3D, with it being the passive type, which are generally easier to wear, and less hassle.

And either type will display the 3D from the PS3, whether it's games or Blu-ray content.

As for "shutters" then lens in the active glasses is actually and LCD panel. It goes black in sync with the television, one eye, then the other, so that each eye sees only its picture. That's why when the glasses activate they seem to get darker. They're actually black half the time. Look at other things around the room while they're on and in 3D mode, like ceiling fans or electronic displays.

Also, you MUST get glasses from the same manufacturer as your set. Sony glasses won't work with Samsung TVs, etc.

I haven't used the passive type 3D TV, my Samsung uses active glasses, so I can't say how they compare. I will say that the quality of 3D programming varies widely, with some that is astonishingly good, making you want to lean forward and touch things, and some that is so bad you get headaches within seconds. My cable system carries ESPN 3D, which is usually very very good, and while mostly shows replays of events, it's occasionally live. I also have on-demand 3D programming including movies and special events. One about the Pebble Beach Concours was excellent, while one about the final shuttle launch was horrid.

Bad 3D programming is usually using 3D as a gimic, and in a very exaggerated way. "Wow, look! This thing is close, and this thing is way far away!" Even though the actual shot might have been of things 4 feet from each other.
