Microsoft's new 3D glassless display

The Microsoft prototype screen can deliver a 3-D image to two different viewers' eyes at once. In order to do so, its onboard computer has to track their eyes to target the light to each individual. The new design uses a lens that tapers from 11 millimeters thick at the top to six millimeters at the bottom, making a slim display possible.

Though the setup currently only has a viewing angle of about 20 to 40 degrees, it's still early in the development stages and will improve in the near future.
