An image of a 3D prototype display from Toshiba. The screen sends out 16 images at once. Glasses aren't needed to see images in 3D, but the display works best when tilted up at a 30-degree angle. As a result, a person looking at the screen needs to hold the screen nearly horizontally. It works best when you stand out about a foot away. The camera cannot capture the 3D nature of the screen.
