Toshiba Confirms Glasses Free 3DTV In The Works

Toshiba released a statement this week saying that they are developing technology for a 3-D television that won’t require the viewer to wear 3D glasses.

Spokeswoman Yuko Sugahara declined to comment on a report that Toshiba plans to start selling the new TVs by the end of the year. Yomiuri said Mitsubishi’s technology involves transmitting different images at various angles to create an illusion of dimension and depth, a principle used by current glasses-free monitors.

“Many people don’t like to wear glasses to watch TV for a long time, especially people who must wear 3-D glasses over regular glasses,” Sugahara said.

NewSight Japan Shows Off Glasses-Free 3DTV

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.

Magnetic3D Glasses-Free 3D

News from Engadget, who reported from CES that Magnetic3D’s autostereoscopic displays claimed up to 9 viewing angles, an improvement over Alioscopy’s 8, plus support for compressed MPEG-4 video and a smaller video player, key for the digital signage market these displays compete in.

The Engadget guys detected “a bit more pop from greater distances and angles than competing tech, but unfortunately what they didn’t see was any indication this technology is any closer to being ready for regular TV watching. The 3D film over the demo 1080p LCD still drops the resolution somewhat and makes 2D viewing a messy blur, so for the time being, these displays popping out ads from street corners or slot machines will have to do.”
