Parallax barrier 3D technology has webcam-based head and eye tracking

Glasses-free 3D panels aren't many, and they are actually rather limited, but people who don't expect there to be more than one person in front of the monitor still buy them.

This time, it is LG that launched a display of this sort, one DX2500 which features parallax 3D technology.

For those who don't know, parallax barrier 3D allows the monitor to track the head and eye position of the viewer and project the two sets of images so that they properly reach the eyes.

Unfortunately, this means that only one person can actually watch 3D media at any given time, or two people, if they sit close enough to one another.

That said, the DX2500 has a screen size of 25 inches and carries a price of 1.29 million won in South Korea, which is $1,131 or 840.89 Euro.

“LG is taking glasses-free 3D monitors mainstream with the DX2500,” said Si-hwan Park, vice president of the Monitor Division at LG’s Home Entertainment Company.

“With the DX2500, we are making the LG brand synonymous with glasses-free 3D monitors. In 2012, we’ll continue to expand our range of glasses-free 3D monitors featuring different designs and advanced functions.”

Alas, LG didn't go into detail in regards to the specifications, so prospective buyers will have to look for listings of it online to learn the resolution (probably full HD), brightness, contrast, etc.

What the press release did make a point of mentioning, however, was the possibility to convert 2D content into 3D.

Perhaps in the future, if media reaches the point when it is all shot in 3D, such conversion technologies won't be needed.

Right now, though, the situation is the opposite of that, with very little actual 3D content available.

The worldwide release of the monitor will take place early next year, probably in January, around CES 2012 (Consumer Electronics Show).
