Is 3D TV Without 3D Glasses Possible?

Any conversation around the subject of 3D television inevitably covers the topic of the cumbersome glasses required to take advantage of this renewed technology. Many believe 3D TV won’t truly take off until the 3D sets function without the glasses.

Recently the Nintendo 3DS handheld gaming device has launched which has a glasses free 3D display. There are also a number of mobile telephones entering the market that also offer a 3D experience without glasses. These devices can achieve this glasses free experience because of their relatively small screen size and requirement to support only one viewer.

The problem for larger televisions arises from the requirement to support a wide viewing angle and large numbers of viewers. Because 3D technology requires different images to be viewed by each eye 3D glasses are currently the only way to ensure a large number of people can view the images in the same way.

Current technology for displaying a 3D movie to many people without glasses involves the use of 16 projectors and isn’t currently a practical solution for home entertainment.

It’ll be a while before you can buy a glasses free TV for your living room.
