According to Technology News website CNET, Toshiba has confirmed that they will begin shipping a Glasses-Free 3D TV to the U.S. in early 2012. No indication was given to CNET on possible sizes for the TV. Toshiba currently has glasses-free 55” 3D TVs for sale overseas in Germany and Japan where they sell for over $10,000 apiece in each country.

The glasses-free model will be a welcome development for a large percentage of 3D TV fans and TV lift cabinet owners. Common complaints from 3D TV viewers, as well as those who have tried but shunned the devices: A) Glasses are inconvenient and can interfere with performing multiple tasks while watching 3D entertainment and B) The 3D glasses and resulting images can cause headaches.

So, how does it work? We frequently touch on the topic of 3D TVs on our blog and the topic of Toshiba’s glasses-free 3D TV has been discussed previously when it was more in its infancy. 3D TV works by presenting each eye with a slightly different image, giving the viewer perceived three dimensional pictures. Typically, the glasses would combine the two images to result in the 3D picture. In the glasses-free model, many tiny lenses project two different pictures from the screen, one to each of the viewer’s eyes. This effect is easier to achieve with only one viewer. With multiple viewers, the TV must ‘learn’ where the faces are located and project images accordingly. This is one major difference between Toshiba’s 3D TV and watching a standard HD TV. With Toshiba’s 3D model, the viewer(s) will need to press a button on the remote to launch facial recognition software. This allows the TV to present the best possible image for all viewers - pretty incredible stuff. We can’t wait to read more about it when the newest prototype is unveiled at CES on Sunday.
