LG in Korea has announced the world’s first glasses-free Cinema 3D monitor.

The 20in DX 2000 display will go on sale for KRW1.29m (about £765) and uses LG’s specially developed eye-tracking technology to make sure the right pictures are sent to each ‘channel’.

Like other glasses-free 3D systems in development the LG system uses a ‘parallax barrier’ system, which puts series of filters in front of the display so that each eye sees different pixels, and so creating the 3D image. Delays in bringing such systems to market have been due to the problems of extending the viewing ‘sweet spot’, since even slight adjustments to the viewing angle can destroy the 3D effect.

But the LG technology also uses a camera built into the display to track the position of viewers’ eyes, and adjusting the angle and distance of the 3D image accordingly. It can also convert 2D movies, photos and games into 3D.

LG says it’s the first company to combine eye-tracking and parallax barrier technologies, allowing viewers to move to different angles and positions without losing the 3D image.

No word yet on when the technology is coming to Europe.
