Glasses-free 3DTV Demonstrated
TOKYO: A display company is
marketing glasses-free 3DTV. NewSight Japan demonstrated a new 70-inch
glasses-free 3DTV at Japan Finetech last week, several reports indicate. The
display is said to use “parallax-barrier technology” that renders viewable 3D
images without glasses. “NewSight Japan” is not officially listed as a regional
subsidiary of NewSight GmbH in Jena, Germany, but both are using the same
technology and model numbers on displays. Here’s 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 is said to have several precisely placed slits that allow each eye
to see a different pixel set, creating the illusion of depth, according to Digital Trends’s Ryan
Fleming. The drawback, he says, is that the viewer has to be specifically
positioned in relation to the screen.
The NewSight GmbH 3DTV displays use a special media player that supports
something it calls an “eight-tile” format. The company says the 3D flat panels
can display 2D content interspersed with 3D content.
NewSight offers 3D displays in 8.4, 24 and 42 inches diagonal. The “purchase
now” link on the Web site doesn’t yield a price, but rather the contact page.
The 70-inch model demonstrated at the Tokyo trade show is said to be the
largest glasses-free 3D display yet.
