Toshiba has manufactured the first ever TV that displays in 3D with no glasses required.
Toshiba explains how they did it.
”The newly developed technological innovation for 3D-TVs without glasses uses an integral imaging system. It 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. Toshiba achieved this thanks to its engineers’ huge knowledge of display technology and of semiconductor and software design. They developed a powerful engine and an algorithm to extrapolate these perspectives out of the 2D frame and used 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.”
Ahhh but of course! – That’s how I would have done it.
