Toshiba prototype display
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.
Philips 3D LCD monitors
Philips is selling 3D LCD monitors to the commercial market and will try to bring the technology to consumer TVs by 2008. The TV is a standard LCD with an additional layer of lenses aligned in rows. These lenses create separate images of the material that, when received by your eye and brain, get interpreted as 3D imagery. The 42-inch screen is meant to be viewed from about four meters away. The 3D effect of the 20-inch screen can be viewed about 60 centimeters away. (If you stand closer, the 3D effects disappear and the image begins to blur.)
