3D TV glasses

[lewis77]

I recently visited the Sony Style store in Las Vegas and was able to demo the 3D tv they had. I noticed that the 3D glasses were quite different from those I used to watch Avatar at the theatre complex.

I also read online that the glasses to be used with the new 3D tv's will be quite expensive $300+ each. Why so expensive? and more importantly.....

Why cant you use the glasses you use during theatrical releases on your 3D tv?????

For the first question: It's probably the initial price.
Just like, you know, how Blu-ray-players and such things were much more expensive at the beginning too.


The second question: Because you're not supposed to take them...

lol

But seriously, I don't KNOW, but my guess it's probably that it has to do with different specifications.
Like, refresh-rates, perhaps the fact that it's projection compared to a TV-technology.
And other things like that.

Maybe also the screen-size or shape even,
maybe you couldn't even use one pair of glasses at a different cinema,
because of each having their own specifications.

But I dare to bet more on the first thing, different technologies...

I believe it's because they use different types of technologies to display a stereoscopic 3D image. Hell, even different types of 3D screens at theaters (IMAX 3D v. RealD 3D) use different types of glasses that are incompatible with each other.

I wonder if that could mean that glasses made for samsung tv's will only work with samsung tv's and so forth...???

If this tech catches on I swear I can see some company making "fashionable" 3D glasses that you can also use outdoors. something that comes to define a decade, remember "parachute pants" & the 80's.

The reason is the technology.

In the cinema, it utilises polarised lenses to force different images to each eye. This is not possible to do in the home without completely replacing the TV technology used in LCD screens.

In the home, they use shuttered glasses, each eye flickering at 120Hz, to force an image to each eye.

This latter method mean that any TV that can display at 120Hz and up has the potential to be 3D ready with a firm-ware update.

It also means that the glasses will initially be supplier specific, since they will in some way need to sync with the TV to know which lens to occlude at any point. The price will drop once third-party suppliers get in on the game.

I haven't seen the glasses used with sony or any other TVs but I know that the theaters use polarized glasses to see the stereoscopic image. TVs from what I have read use shutter glasses that need to get a signal from the TV to know which lenses needs to be open or closed to stay in snyc with the TV. I am not getting any stereoscopic TV I am wait until they have auto-stereoscopic projectors. You don't need glasses with them and they are around the corner. Probably once this technology become popular they will put out auto-stereoscopic TVs. Kind of like blu-ray and this new hdmi 1.4 spec and 1.3b and c have not even been popping up much at all yet.

As for "intercompatibility", I think it would be pretty similar to remote-controls.
The original remote-control that came with the TV would work best, as would be the case with the glasses.
However, you can also get alternative remote-controls and if they support your TV they would work.
It would probably the same case with 3D-glasses; I guess a brand like Logitech would be on top of it soon enough.

If glasses from one TV would work with another...
I think, again like with remote-controls, with a little luck they might work.
But if you want to be guaranteed the best results, you should use the original devices.
Unless of course alternative ones support it.

Oh, and they probably want to make you buy multiple glasses for use with multiple viewers too.
So that your guests couldn't just bring theirs while they have a different TV usually.
I'm sure they'll want to sell as many as possible...

honestly the one thing I learnt with all the years of "reading on line" is wait and see the final product. It is not that it is all BS but often there is enough BS to make it irrelevant. I remember before BD launched people saying BDs would cost 100$ because replicating them would be over 70$. Now that was obviously insane and anyone with a brain could see that, but in this case it is more complicated to determine the difference between facts and fiction. There are 3D ready TVs already out there, is this 300$+ a kit to make them 3D (for example converter box and 4 glasses)? will 3D TVs sell with glasses or will they be sold separately and 300+ can be for more then one? Is the 300$+ the cheap pair or the ultra deluxe?.... until there is actual product on store shelves with actual prices I think there is a bit too much confusion to put into the prices too much credence.

well for one thing different theatres with different set-ups would use different glasses. So you cant necessarily use the same glasses from one theatrical presentation to an other (if they are in different theatre rooms). But the same will be true for home, if they are shutter glasses (most TVs so far) then they need to synch with the TV and be able to match its speed, if it is polarized then they need to be polarized the same way with each eye

[Grif32]

They have links up for the shutter glasses which are $150/pair. Not $300 but still way to pricey IHMO

And to answer other questions. Yes if you buy a samsung tv you HAVE to buy Samsung glasses. Sony's glasses will not work.

But someone posted a link in the avsforum that someone company is making glasses that will work with any tv.

If you stop by a BB store and watch the 3D TV, if you can, with the glasses on take a look at the blue light on the player. You will notice the shuttering of the glasses which is not noticeable while watching the TV.

I will def. have to try that out.

[quetzalcoatl]

For interchangeable glasses it looks like the only early option will be the XpanD X103 and X104 the 104 will be compatable with all brands it looks like since it will have both bluetooth and IR. But is rumored to be $250 a pair. Not cheap if you need multi pairs.

if u check BB ad u c the 3D glasses r battery powered & a $350 value. they have a package deal tv, player & glasses i think its $3400 no 3D 4 me anytime soon....

How big was the tv?

$3400 is expensive (especially if the tv is 40" or smaller). However, the idea of watching Avatar in 3D in my own home makes me wanna go out and spend that $3400 right now, lol!

Thats the biggest problem I see with the glasses being expensive. In my household I could get away with just two (for my wife and I) but what if I have more people over? Sucks as of now but i'm sure like every other electronic, the price will go down substantially within a year or less.

Its true each technology is different, Samsung 3D glasses only work with Samsung televisions, Panny's only work on Panny's and Sony's will only work on Sony televisions... Each technology is different and can not be interchanged....
