NewSight Japan gave a demo of their new 70-inch glasses-free 3DTV at Japan Finetech. The new model is said to use “parallax-barrier technology” that renders viewable 3D images without glasses. According to the NewSight GmbH’s description:

“The NewSight parallax-barrier technology allows the viewer to see the 3D image ‘naturally’ in the way people are used to viewing normal 2D displays. The technology subdivides the LCD image into complex repeating segments that, when viewed and then integrated by human binocular vision, presents 3D views of scenes. The special parallax barrier is affixed to commercial-grade LCD displays in a precision assembly process.”

This barrier apparently has a number of precisely placed slits that let each eye to see a different pixel set, creating the illusion of depth, according to Digital Trends’s Ryan Fleming. The drawback is that the person watching the 3dtv has to be seated in a specific area in relation to the screen.

For glasses-free 3D TV to really take off, this will be it biggest hurdle.
