Look ma, no glasses!

At KES 2006, LG demonstrated its Flatron M4200D 42" LCD capable of displaying 3D images. While all the conventional HD specs are present with 1920 x 1080 resolution, 500cd/m² brightness, 1600:1 contrast ratio and 8ms response time, the main feature is its ability to generate the illusion of a three-dimensional picture without the need for external glasses or goggles.

Those who were in attendance to view the display say that the 3D effect it creates is quite convincing. The only condition that the viewer must meet, and it's an important one, is that he or she must sit at an exact distance away from the screen.

The 32" version of LG's 3D LCD that was on display at the IFA show in Berlin early September specified a viewing distance of 4 meters or 13.1 feet. Any greater or lesser to that viewing distance and the 3D effect would be lost. Steps to the left or right, however, do not affect the 3D as long as a constant radius could be retained, according to TrustedReviews.

The 3D system is reportedly lenticular-based, which we assume that LG incorporates by laying a plastic sheet embedded with tiny lenses and prisms over the M4200D's screen. This facilitates the 3D effect without the need for glasses, though content intended for reaching the third dimension must still be anaglyphically encoded.

While the images do nothing in way of conveying the 3D effect, we can see that the crowd of observers all keep a similar distance away from the display.

LG has yet to announce pricing or a release date for the M4200D, but it's something that we will be keeping our collective stereoscopic eyes on.
