Toshiba Introduces World's First Glasses Less 3D Tv :

The world's first 3D Without Glasses television that doesn't require glasses has hit the market. Toshiba unveiled the high-definition liquid crystal display 3D television that does not require the special glasses - one of the biggest consumer complaints about the technology. The Tokyo-based company hopes this could be the breakthrough that brings 3D TV to the masses.

The Regza GL1 Series TV which combines image processing technology with a double convex sheet to render depth-filled images from any angle using parallax. Most 3D TVs on the market today rely on glasses to deliver separate images to each eye, which creates a sense of three-dimensional depth. In its new TVs, Toshiba uses a 'perpendicular lenticular sheet,' which consists of an array of small lenses that direct light from the display to nine points in front of the TV. If a viewer is sitting within the optimal viewing zone, the brain integrates these points into a single 3D image. Many might be put off by the fact that they'll have to be very close to the screen for the 3D effect to really work - not to mention the steep price tag.

Toshiba will offer two sizes - 12 inches and 20 inches. The technology is not advanced enough yet to integrate into larger screens. Suggested viewing distance for the 20-inch model is 90 centimetres (35.4 inches) and 65 centimetres (25.6 inches) for the 12-inch size. The TVs will go on sale in Japan in late December, Toshiba said. The smaller version will cost about 120,000 yen (£912), and the larger one will be double the price. The company did not release details on overseas availability.
