Microsoft Research is shopping around a new 3D Display technology that can present stereoscopic images to 2 user simultaneously without glasses using special lensses.
The new lens, which is thinner at the bottom than at the top, steers light to a viewer’s eyes by switching light-emitting diodes along its bottom edge on and off. Combined with a backlight, this makes it possible to show different images to different viewers, or to create a stereoscopic (3-D) effect by presenting different images to a person’s left and right eye. “What’s so special about this lens is that it allows us to control where the light goes,” says Steven Bathiche, director of Microsoft’s Applied Sciences Group.
This is different from displays like the Alioscopy display which are based on lenticular lenses, and is a mere 11 to 6 millimeters thick, making it easy to add to existing displays and projectors.
