The popular method of creating a 3D image on a TV these days is to rapidly show two slightly different images one after the other. Active shutter glasses block the view of the eye that is not supposed to see the image by darkening the lens over that eye. Because each of our eyes see the world from a slightly different perspective our brain is deceived into thinking that the image has depth of field.
The glasses you need for this experience can be expensive. A TV capable of the high refresh rates required for 3D display is also a necessity. If you have a TV that is more than 4 or 5 years it is most likely not 3D capable. Many TV brands have their own specific models of shutter glasses so your next step is to invest in these. They're expensive and if your whole family is watching the same movie then there is quite a few dollars worth of equipment sitting on your faces.
Thankfully technology moves onward and upward at a great rate of knots and new equipment is already coming into the market place which promises to solve all of these problems. New projectors and TVs are now available, albeit at a rather large cost, that use the same technique currently used in the movie theaters. Movie theaters work by projecting the image with polarized light. Each lens on the polarized glasses will only let one image through while blocking the other. As a result each eye sees a separate and slightly different picture than the other. Refresh and scan rates are not as crucial as both images are shown at the same time.
For mostly solo viewing you can purchase LCD screens for 3D viewing without glasses. The LCD screen is configured in such a way as to be able to project the two separate images in different directions so that each eye will only see one of them. The technology behind how this is done is always a closely guarded secret. A major disadvantage of this technology is that it is not suitable for a widely dispersed audience. The reason for this is that there is a sweet spot which the viewer has to be in in order to get the two images correctly aligned. If a viewer's eyes are not correctly aligned to the images then they will not get the 3D illusion.
We might not see it for a while on a large scale on big TVs but it is available as a cool 3D effect for games on the new Nintendo 3DS games system. As there is usually an audience of one with a personal gaming system then this technology is an excellent way to bring 3D gaming to the masses.
