The gaming company, Nintendo is immersing the glasses-free 3D technology in the market, which is a new technology and needs some more adoption, however it can't be used to make 3D TVs, not yet.
Why? Because the glasses-free 3D simply fades away if you are not in the right angle, it can be well used in gaming devices because it for 1 person and has a small screen, this technology was already adapted on the Nintendo 3DS. It has a clever display developed by Sharp, which generates a tiny layer of stripes that makes your right and left eye see different images, this tiny layer of stripes is the autostereoscopic parallax barrier in front of the the high resolution LCD screen.
And this explains more how the 3D depth and space slider works, it controls the space between these tiny stripes with the ability to completely turn them off and make the device stop generating 2 layered images and show the regular flat 2D display.
Even in a small screen, if move your head too much, the 3D effect fades away the same way, in a larger scale it is even worse, and very expensive, it isn't a good technology to use in a big 3D TV -yet-, like 2 TV companies showed on this year's CES:
CES 2011, 2 types of glasses-free TV were displayed to the public, the first one had a very depth and "strong" 3D effect, but a very limited space of view for a TV, the other one had a larger space of view, but the 3D was weak and even tough you could see it from almost all angles it was considerably flat.
But...How about these air-plane screens? yes, the autostereoscopic parallax barrier technology Nintendo is using could fit perfectly into air planes screens, (in first class cases) it is only for 1 person, you actually isn't supposed to move around your seat so keeping your head at the same place won't be a problem ein? They could even install cameras in the nose of the plane to display full 3D take-offs and landings!
The concept for creating glasses-free 3D illusions is an old idea, but only today with the high resolution LCD screens it is becoming reality, i guess we are beginning to see the how one day every screen will have a 3D display, a Sci-Fi like world, where each screen has depth and space displays, everything glasses-free, in all angles, in high resolution and much, much more, this kind of 3D is only one.
Reading is good, writing also is! you are free Leave some words bellow, and these words are welcome
The way I understnd it, it works like those plastic bumpy giftcards, the ones when you rub your fingernail across it it makes a zip sound. Those are 3D, and theyre pretty awesome.
Uhm, in a figurative way the paralax barrier is the glasses but in reality it just adjusts each angle of your view, and where each of your eyes has to look at
