"Toshiba has launched a large screen glasses-free 3D TV called the ZL2. The TV features a multi-core processing platform and a Quad Full HD display, offering up to 3840 x 2160 resolution.
The glasses-free 3D technology draws upon the parallax technology we have seen in the likes of the Nintendo 3DS, but on a very large scale. The problem with parallax screens is that you have to be positioned squarely in front of them to see the 3D effect. However, the front of the Toshiba screen features a range of lenticular "lenslets" that guide the dedicated images to each viewer, providing 3D images in up to nine different viewing positions so that multiple people in different positions in a single room can enjoy the 3D without glasses.
There is also face-tracking technology that can define the actual viewing positions in front of the TV which directs the images precisely to the eyes that are watching the TV, wherever they move. Toshiba did not announce the retail price of the new TV, but said it would be available in Europe in December this year..."
