How 3-D TV Works

Those glasses are similar to the kind issued to military recruits in basic training. Except, the GIs have a nickname for them: BCGs (or Birth Control Glasses). Who the heck would want to wear such an ugly, cumbersome, heavy thing?

First off, does it have to be so ugly? Two, does it have to be so big and bulky? Three, will it require batteries or some other kind of power source to work? Can somebody call up Ray Ban or Giorgio Armani and have them design something waaay more fashionable? BCuz if they look like that, I'll just forgo 3D altogether. I'd rather get laid than watch Coraline in 3D.

Corinne Iozzio you don't seem to understand this technology very much. Most TV's even new 120hz displays can not do 3d and this is not because they don't have a separate chip or an ir transmitter. The only reason is that they cannot display from a 120hz source even if they claim to be 120hz displays. Instead they just mix two frames together to invent what they think the ones in between might look like. This is more or less useless. There have been some tv's from Mitsubishi that can do a real 120hz but only in dvi. If you want a tv that will display 3d over hdmi you need to find one that is clearly labeled hdmi 1.4 120hz and has a big 3D. Some displays might be software upgradable from hdmi 1.3 to 1.4 but there is nothing out yet.

I've used shutter tech on a monitor capable of 140hz. Not LCD mind you, CRT, but the effect is similar. I would certainly not recommend it as anything more than a novelty. Yes you can see 3d out of it, although there's a number of issues from ghosting to brightness. It will also induce a headache after long periods of use. I would definitely not want to sit through a 3 hour movie with it.

I'm more interested in the tech they use in the theaters now that is based on light polarity. No shutter needed, each eye receives a solid image so no headaches or brightness issues. And the glasses are cheap and don't require batteries. If the big plans for 3d everyone is talking about are contingent on shutter glasses I'm not the least bit excited...

LOL...Corinne did you change the picture of the glasses from the ugly red ones to the newer, slicker gray/black ones here? Awww...

At least these are a bit more stylish and not so big as the red ones that you had put up before.

I saw a system which didn't use glasses a couple of years ago (UK, 2007).

The system used some kind of multifaceted mirrors for each pixel on the screen. (Each pixel actually had 16 different faces, all of which faced in slightly different directions and could show different colours).

This allowed the system to produce a 3D image without the use of glasses. I think it was a Panasonic device but I cannot be certain. It was around 42" flat-screen and wall mounted. The demo involved a number of animations and one flyover of some Scottish mountains.

They also had a demo of an Ultra High Definition TV (2160p). This was truly incredible to my eyes, the demo video was of a motorbike rally. The storage device from which the video was played back was like a full sized UMD, A Blu-Ray disc held within a cartridge which also housed a solid state memory device which I think was something to do with DRM. The jump from 1080p to 2160p was immense, like going form old VHS to DVD.

Even if the technology is not there yet, its a start and the normal evolution of improvement will come as the market develops. We will have 3D TV, but give it a couple years. Avatar did its job.

I wonder if we can save the 3D glasses from the Avatar movie and use them with these new 3D TV's ?

It's a shame that 3d tech is wasted on sports. Should be used for education.

Let's get honest here... we all know the real commercial driving power behind home 3D tech is going to be 3D Porn!

Are these 3d tv's capable of converting normal TV programming to 3d or only of showing already 3d programming.

The 3d glasses from avatar will not work on these tv's. They use completely different tech. Movie theaters use polarized light. To me, this is a better way to go, polarized glasses don't require a power source and anyone could use a regular pair of eyeglasses to watch it as long as the lenses were polarized which would be easy enough to do. Maybe the manufacturers can't figure out how to filter the light with lcd or plasma tv's but it would definitely work with any front or rear projection system.

Camacho only some movie theaters use polarized filters, their are many that use shutter glasses instead. You can recognize these theaters because they will have the anti theft door things up and will make you give the glasses back instead of the recycle bin. These glasses cost like $20 to $40 so they use an expensive dishwasher to clean them and use them again and again.

Porpoised light can be filtered out with a porpoised filter positioned perpendicular to the light, one that is parallel will allow the light to pass through. There are some magic liquids that crystals and rotate polarization of light when a little voltage is applied. Lcd tv's use this to make the display work. There is really no reason you couldn't add another less expensive layer of this to any display to make polarized glasses work but it will cost you a sheet of it the size of the display and that will add cost. At a movie theater they only need a small one up by the projector and it lets cheep glasses work. But they still need the high refresh rate. At home it will be less expensive to just use shutter glasses, both ways of doing it degrade color a little but the shutter glasses degrade it less so you really want to use them anyhow.

If I want to watch something interesting in 3D, I would take a walk in the park. Better for the heart and I might actually meet someone that would talk back.

Oh, you know I saved my Avatar glasses. I worn while I drove home from the theater. They made everything look so... 3D. This technology is amazing!!

would it be cool to not have to ware those 3D glasses or would it be a night mare were you cant tell from a fake wall from a real one and people will have heart attacks because some one thinks its funny to use a 3D TV for a prank.

Hi guys

Wait till we get neutrino signals being sent through the earth! Video quality (in 3D) directly on your phone! Check out Pirelli labs stuff! Wow! Well! Joseph Weber said it was possible so why not?
How do I make a good qaulity 3D projector from available off-the-shelf stuff? I mean something that will give me images similar to the IMAX technologies? Anyone give me the info please?
Just love 3D stuff!

Thanks

Guess ya’ll are some of the million geniuses who spent twice the cost of a DLP on an LCD, so you could say your TV is 4”thick, not 13”, and you can hang it on the wall. Now that you’re under sized, overpriced, out dated TV is sitting on a 13” thick stand, and you are saying that it is the manufacture’s fault you didn’t do your homework. DLP’s pitched 3D ready on every box, but the salesman got a higher commission for pushing you into an LCD.

i'm looking for issue of 1957 in those days i had been to clock made out of wood that is all the parts were made of wood and in place of spring the designed by bicycle spark wire may i get that design again?

I'll be really glad when people stop digressing about the how rediculous they would feel wearing glasses while watching a 3-D movie on TV. That's a self-esteem problem. If you're alone, who will care what you look like, unless you like to have a big mirror on to of the TV set so you can monitor your apperance constantly? Your next door neighbor won't care. Maybe if you have a superbowl party, you can look at each other and laugh instead of watching the game. Billions of people wear glasses for seeing, reading, goggles for scuba diving, welders helmets, safety glasses, tinted visors for flying, sunglasses for driving. They don't feel rediculous, nor do the millions who wear stupid looking sunglasses.

You're going to wait forever for a single display to direct a separate image to each eye for a wide viewing angle without dedicated glasses.

I've seen 3-D and it's really great. It's worth putting on a pair of cool functional-looking glasses like the Panasonic shown in the article. They probably have to have wide rims to keep out light from the side. I can't wait to get a 3-D system, but I wonder about them getting fogged up from evaporating sweat.

why could they not use that technique to black both sides out at the same time, and alternately show the images of different shows. Then two people could watch two different shows on the same tv. If you're already wearing silly glasses, im sure headphones wouldn't be too too bad?

-well what we have here is indeed an effort to promote a relatively archaic technique of providing a quasi-3D effect. While not suitable for flat-screen home-TV usage, a usPat.#7,180,663 was issued in 2/2007 to a pvt.-inventor which has developed a 3D w/o-eyeglasses system that conveys a credible illusion of 3D for motion-picture theaters, --in so long as either the camera is moving, or the subject is moving; -otherwise the illusion retreats seamlessly into conventional 2D (ie: length & width, but no depth). However, do not despair, as my partner and i have invented a true constant 3D-technique which we've developed to the point of a working prototype, from which we're preparing to introduce via a DVD-sampler. This Barker-Vonheck/3D-System employs no primitive eyeglasses, yet enables constant 3D depth-perception for HD-TV, which will likely first be introduced for video-integrated Cell-phones, and 3D/RV-mirrors for cars & trucks; --but will be suitable for ones PC-screen, TV-screens, and yes even large theater-screens! We've not yet conducted any licensing of our advanced proprietary 3D-technology, pending approval of our Pat.Attorney, --but suffice to say we expect to make a much more concise disclosure of our revolutionary development via Pop.Science-mag. when the time is right later in 2010. Meanwhile, anyone interested can reach the developers via-

The 3D TV idea is really nice but i thing that films in 3 dimensions should be watched at the cinema with a very large screen so that the feeling will be as real as possible. Also, in most movies you don't need 3D, it only gives you a headache. Avatar was nice but when i watched Alice in wonderland it was completely unnecessary.

Philips is going one better than 3D TV with its ultra-widescreen, cinema-style 21:9 aspect ratio 3D-TV. National Lottery  |  Spanish Lottery That's over 30% wider than standard widescreen, but it's not out until later this year; Philips 9000 series tellies are all 3D now.

The first 3D television set has gone on sale in the UK today, but consumers who rush to buy one may end up disappointed, experts have warned.John Lewis is selling 40-inch Samsung models from its flagship stores for £1,799. The sets will be available in other John Lewis branches and Curry’s and Comet and Link Directory over the next week.

Panasonic is expected to launch its version next week, with Sony following in June. However, viewers will not be able to enjoy the full effect of the new technology until later this year with the launch of Sky’s 3D channel, which will show football, documentaries and films. There is only one Blu-ray film available in 3D at the moment, Monsters Vs. Aliens.

3D TV will soon be a relity and people are very excited about it, and they should. I think sports fans will benefit the most from the new 3D technology. marty @ http://www.home-theatre-systems.net

3DTVs are becoming more and more popular and the best thing is that they now provide the option of turning your 2D old movies into 3D http://www.hotel-bucuresti.com/hoteluri/hotel_razvan-113.html

Companies are rolling out more and more 3D products for sports and home theater fanatics. I love it and I will soon buy a 3D-ready LED TV myself. Bob from http://www.expertulpc.com

Audiences first got a glimpse at 3-D technology way back in 1922 with the release of "The Power of Love." Whether they thought it was a curious thing or not is lost to history. But that began the somewhat cyclical fascination with three-dimensional film.

In any case, when 3-D TV is actually ready for prime time, you won't be using the funny paper glasses with colored lenses, said Jim Mainard, the head of production development for DreamWorks Animation. Instead, you'll be using the funny plastic glasses with polarized lenses.

I've never seen a 3d TV image, but I'm dying to. I wonder how it compares to 3D Cinema. The problem is that we're so used to one way of viewing tv, this is going to totally change that.

We'll see if it sticks.

ok this is the 3D but going down i guess with the new technologies. The new tehnologies serve us 4D confort. In the nearest future this will be 5d. 5D means we will receive some water or some movements on our legs - let say bats flying.

The technology is getting developed each day. Just remember the old TV s from 20 years ago.

It will be interesting to see if this really takes off. I still haven't got used to HDTV. Looks so fake to me. Maybe 3D will be better!

3-D TV has taken off big time in Canada. Guess because of our long cold winters. This time I'm going to wait for prices to drop. http://www.calgary--hotels.com

This is really cool as 3-D for some movies is pretty awesome. For example Avatar was excellent in the theater so if we could get a similar experience at home that would be great. On the other hand, some 3-D movies (thinking of some of the animation kids films here) were a complete ripoff and it seems the only reason they made them 3-d movies were to charge extra fees. Overall though a 3-d tv may be a worthwhile purchase.

To those considering the purchase of a 3D TV... heres my review.
I own a Sony Bravia 55" 3-D TV. Its AMAZING! For the skeptics out there who said at the beginning of the comments that we would never have a good 3-D TV, or that it cannot compare to the theaters, I'm calling you WRONG!
My favorite is the Super Star Dust 3-D game that comes with the TV. When my ship blows up it fills the entire room with showering sparks of shrapnel. Well, not literally, but it appears as though it does. The graphics on THAT game are nothing short of mind blowing. I have played other games with great effects as well and I recommend a 3D TV for GAMES, not movies. But we're all different, right? Now, regular TV for us is nothing special. It does seem to give a sort of depth to it, but you don't notice it being 3D till you remove the glasses, and turn the 3D effect off. The 3D on TV is more of a reverse 3D, looking like it is set deep into the screen rather than coming out the front.

When I bought this TV I also opted for the extra (additional) 4 year warranty. I have replaced a total of 4 HD TVs in the past 6 years. The warranty is part of the purchase and necessary to protect myself from the expensive mass produced junk.
With that being said, this mass produced TV may last 2 months, and it may last 20 years. Time will tell, however I will LOVE the crisp clear 3D picture till it dies. And I couldn't care less about the cosmetics of the glasses. Im watching TV, not posing for a date!!! The former person who said get some guy to design a fashion series... all I can say is ISN'T $150 A SET EXPENSIVE ENOUGH FOR YOU ALREADY???? YOU HONESTLY WANT TO ADD DESIGNER FEES TO THAT??? Thats just silly nonsense. The glasses work GREAT, though they do have 2 flaws.
1) They lose effect if you tilt your head out of the straight on view (very narrow field of view) and
2) They are nearly IMPOSSIBLE to clean, and even harder to KEEP clean. I swear fingerprints fall from the sky onto these glasses. From a person who does photography and is used to cleaning glass lenses, these are the pits.
But the picture they create can be amazing in degrees associated with what it is you are viewing, and whether or not it's created for 3D. Dont expect to buy one of these TVs and watch satellite TV in 3D. You'll be disappointed. We purchased this because we needed a TV, and because the future is clearly 3D. At only $400 more than a standard Vizio LED LCD, I feel it was a wise choice. (It was $1600 for standard, $2000 for 3D)
Another thing to consider before you buy any 3-D TV:
We only watch this TV in 3D mode about 1/10th of the time. WHY? Because the TV came with 2 pair of glasses, not 4. We are a family of 4. It took 2 weeks to pay the extra $400 from the return, especially in December with Christmas nearing, which is when we got it. I can't afford another $300 at the moment, so for now its a very nice LED LCD TV until prices drop on the glasses or till I get a nice bonus check.
Do I recommend it? YES. Just do your homework. You WILL need more glasses if there are more than 2 people in your home and they ARE expensive. Even on ebay, they are selling for nearly $150 a set. FORGET used prices. No used 3D glasses. The technology is too new. But at $40 a pop for a family of 4 to see a movie in theaters, I do think they are worth the money, and they will pay for themselves if you frequent the theaters. This comment dated 12-27-2010

The 3D is great, forget green and red side by side. I have a Mitsubishi 60738 and a Panasonic DMP-BDT300 that outputs a checkerboard input to the Mits. Not all 3D components are compatible betweeen brand, I had a Sony BDP-S370 3D Blu-ray, did not work with the Mits. Do your homework. The Mits need an emitter that plugs into the TV, this sends the shutter signals to the glasses, price is $399 and includes two glasses. However there are generic units that work, I am using the 3DTV Corp (brand name) emitter which you can purchase from Amazon with 4 glasses for $195. Both the Mitsubishi TV and the Panasonic Blu-Ray 3D units can connect to the internet and also stream internet content such as Netflix and Youtube. REMEMBER, just because a unit is 3D compatibledoes not mean it will work between brands.
