3D televisions and 3D movies?
Ok so what is the purpose of making these new expensive “3D” televisions? Is it not the combination of the actually movie being In a 3D format (two main colors offset making it blurry to the naked eye) and then the glasses which filter out the color offset creating a 3D effect? For example my son watches Spy Kids 3D and with the glasses its in 3D on a regular old tv not even an HD one. Are they trying to promote a better 3D?
Cause I mean when crap pops off the screen, it pops off the screen. I just wanna know the difference, I see the depth in his kids movie on an old tv with a old dvd player and paper glasses! Why do we now have to buy a new “3D” TV?
The idea of 3D is that each eye sees a different view. There are several ways to do this. The cheapest way is to tint one image red and the other green, and look through glasses that are red on one side and green on the other. The film or TV show has one green frame, then one red frame. This works okay but its cheap and it doesn’t look that good and it gives you a headache after a while,
In movies they use a different system. There are two pictures shown on the screen with polarized light. The glasses are polarized at 90 degrees to each other so each blocks out the other’s picture. This is a little more expensive and it works a little better.
But the way 3D TV works is the most expensive way. Each lens of the glasses is an LCD shutter. It goes black when the frame for the other eye is being shown. The glasses get the timing signals by plugging into the TV (actually there’s no reason they couldn’t be wireless). They cost a lot of money. Three or four sets come with the TV, and extras cost like $100. If someone comes over to watch TV with you, he has to bring his own 3D glasses.
I’ve never seen 3D TV, but it’s going to have to be pretty damn good before I would buy it. Everyone in the US has bought a flat screen within the last few years, an LCD or Plasma or whatever, and they’re not ready to buy a new set just yet. So I don’t see it being a big thing, at least not right away. Plus 3D won’t do much for The Simpsons or Family Guy. Dancing With the Stars, maybe.
We have an IMAX theater in San Francisco that, when they first opened about 10 years ago, they promised 3D picture with the LCD glasses. There’s even a socket in the armrest of each seat to plug them in. But they’ve never shown one there, all the 3D movies they’ve shown there were with polarized glasses. I’d like to see it with the LCD glasses just to see what it’s like, if it’s any better. My guess is that the glasses were just too expensive for them to make the investment.
