3D TV is one of the biggest revolutions that we’ve had in entertainment since the TV went from black and white to colour, but the big problem that has been getting in the way of its success so far is the need to use 3D glasses. This is because wearing glasses isn’t a natural or necessarily comfortable thing to do, so with the development of the technology to provide 3D without the glasses could be the breakthrough for the technology.
So far there have only been two television sets which have been released on to the market which offer 3D television without having to use a pair of glasses to watch in 3D, and both of these sets have been produced by Toshiba, and so far are only available to the Japanese market. These two sets are also much smaller than what we would normally accept as the size of a TV these days, measuring in at 12 and 20 inch screens respectively.
The approach from Toshiba to the subject of a wider release for these types of television sets has been softly-softly so far, and they have already stated that to develop sets which will work in larger sizes is already a few years away. It has also been confirmed that Sony is also working on television sets which allow you to view without requiring 3D glasses.
From the relatively small sets which have been released by Toshiba so far, the technology works by using what they call an integral imaging system. What this does is to provide the eye with a total of nine perspectives which the eye and brain superimpose to form a 3D image.
Key to the techniques which are used in these Toshiba REGZA sets are a variety of lenses and a perpendicular lenticular sheet which allows the brain to superimpose the different images to give the complete 3D images.
Another benefit to these 3D TVs is that they aren’t exclusively 3D, they can also play regular 2D content, unlike some of the prototypes which have been displayed at the technology fairs historically.
Toshiba claim that it is this technology that allows the viewers to actually move around and not have to stay in a fixed spot to view the 3d images, and also claims that it won’t trigger the kind of ‘nauseous’ feelings which many people report when using other glasses-free 3D devices, such as the recent controversy regarding the Nintendo 3DS.
