3D capable displays are becoming pretty commonplace, but not everyone likes them. The problem is you either have to wear glasses to see the 3D, or are limited by the viewing angle with the non-glasses solutions. Even if you get it right, some people still feel sick after a while due to the way in which our eyes are being fed the 3D image. What we need is for someone to come up with a proper 3D display that doesn’t even need a flat screen.
Burton Inc. is attempting just that and has demonstrated a new, true 3D display that uses a laser to create luminous points of light in 3D space.
The technology used to create the display has been knocking around since 2006, and is a joint collaboration between Burton, the National Institute of Advanced Industrial Science and Technology (AIST), and Keio University. It works by using the oxygen and nitrogen in the air to create a “plasma excitation.”
In this early prototype the display can project 50,000 dots per second and works at up to 15 frames per second. It is hoped that can be increased to 30 frames per second for a very smooth and eye-friendly visual experience.
While the video below shows everything rendered in green, the system is actually capable of full color by using red, green, and blue lasers together. It also has the benefit of working both in air and water, which could make for some interesting TV sets of the future.
It may be a while before this technology becomes good enough to replace our 2D display TVs, but there are high hopes to get it used as a form of digital signage soon. That’s sure to catch your eye more than a poster or video advertisement does, at least until it becomes so commonplace no one notices it anymore.
