If the thought of watching 3D in your living room whilst wearing a pair of glasses is a little bit too much for you, then you might be interested in hearing the latest news from Toshiba from Japanese tech show CEATEC.

The company has just unveiled the world's first mass-produced, commercially available 3D TV without glasses.

There are actually two televisions going on sale: one with a screen size of 12 inches (30.5 cm) and another with 20 inches (50.8 cm), allowing viewers to get a three dimensional viewing experience comfortably, without the need to wear 3D glasses.

The products will be available by the end of December 2010 in Japan.

Glasses free 3D TV is the holy grail of 3D in the home with consumers and manufacturers keen to offer ways of getting around the need to don the specs.

According to Toshiba its new breakthrough "provides nine different perspectives (parallaxes) of each single 2D frame which the viewer's brain superimposes to create a 3-dimensional impression of the image".

The tech is enabled by a, "powerful engine and an algorithm to extrapolate these perspectives out of the 2D frame, [as well as] a perpendicular lenticular sheet, an array of lenses, that enable the viewer's brain to superimpose the perspectives. It also offers a wide viewing area in front of the display and allows movement of the eyes and head without disrupting the 3D image and without the discomfort sometimes associated with other 'glasses-less' 3D technologies".

Like OLED, Toshiba says the "small screen size 3D TVs without glasses are targeted at a small group of early adopters".

"The commercial launch of our 12-inch and 20-inch 3D TVs without glasses in Japan is a first step into the 3D future in the consumer home cinema market", says Sascha Lange. "But it will take several years to develop larger 3D TVs without glasses with screen sizes of 40-inch and more at a yet reasonable price point".
