How do you create 3d television?

Well so far all I have seen for tv is the field sequencial 3d system that uses shutter glasses, and I did have one for the old tube televisions about 10 or 12 years ago.

Before I explain it first I should say that in a 3d movie you need double images for everything and then only one image can go to the right eye and the other image only to the left eye just in case you didn't know that already.

Now for shutter glasses the way those block and unblock the double images is first they use electricity to open and close. When one lens is open the other closes. Then the closed one opens and the other closes and they do this back and forth very very fast.

Now when one lens opens the image for that eye flashes on screen so it can get to your eye. Then when the opposite lens is open then that image for that eye flashes on the screen and they go back a forth like this so many times per second.

Now the older field sequencial systems will not work on the newer plasma and lcd televisions so they need to make new ones. Also since you have all those images flashing so fast on screen you need a tv that can refresh the screen all those times per second. Now tvs only go at 60hz and they are needing to double that to 120hz for 3d. I already noticed at best buy almost all their tvs are 120 or higher.

If your tv already can do the higher refresh rate you are still going to need some kind of convertor box that can get the glasses to open in sync with the images on the screen.

Shutter glasses is probably what you will see for the next few years. There is a non glasses 3d television that is around. They way it works is each pixel has tiny mirrors that can angle its image slightly to the left or to the right. If you stand 12 feet back from the television then all the pixel images will angle into the left eye or into the right eye. Problem with this is only so many people can watch the tv because you can't be closer or further than the 12 feet becuase the images will not angle into your eyes.

Now I don't know about this but I have read a couple times that they have done a television that can do the polarized 3d like they have at the theaters. If true then that 3d works by having one polarized light wave for the right eye and a different polarized light wave for the left eye. Then the glasses have polarized filters that just block and unblock the correct light wave. This format is nice because you don't need electricity for the glasses to work and you don't need to sync them with images. Both field sequencial and polarized 3d look fairly identical. So far tv can't do the polarized 3d format because it can't produce two different light waves. Just color and brightness.

So for tv to get away from the red and blue 3d that uses color to block and unblock images, you are going to have to have a television that is made to do these 3d things that they can't do right now.

I've been asking this for years. I remember back in the 70's, there was a 3D horror movie on TV that you could view if you had the glasses to go with it (which you could pick up at your local convenience store). If regular TV can show a 3D movie, what's so special about 3D TV?
