MIT Bring Glasses-Free 3D TV A Step Closer
Glasses-free TV edges ever closer, as the MIT Media Lab Camera Culture group offer a new way to create a 3D image that doesn’t involve those silly glasses and doesn’t rely on holographic technology that is still a long way from being workable for a TV. Their approach offers multi-perspective angles (like holograms) and, this is the winner, no glasses.
They’ve called their new approach a Tensor Display, and it requires using layers of liquid-crystal displays (LCDs) to build up the image. Using this method, to produce something that will create a convincing 3D illusion, you need a refresh rate of 360 times a second, which is 360 hertz. We already have LCD TVs that have a 240 hertz refresh rate and they believe 360 will not be too far off.
This new method might not have the clarity and quality of a hologram, but until holographic TV comes along this way provides a cheap, workable, effective way of creating a 3D image. The video above explains this composite trickery and you can learn more about it on the MITnews blog.
