3D TV: Not So Fast

LG Electronics has become the latest consumer electronics firm to show off a 3D display, only to show off again that the technology is nowhere close to ready for for consumer use.

Unlike a display that Sharp actually put into some laptops a couple of years ago, the 42-inch 3D Monitor that LG showed at the IFA trade show in Berlin is viewable from a considerable range of distances and angles. While it gives an effective illusion of a 3D image, it appears to be extremely difficult to get the foreground and background of an image in focus at the same time. An LG spokesman explained that while this limitation can be improved by careful encoding of the video—and some of the test videos did come close—the focus problem is an inherent limitation of the technology as it exists today.

Right now, the display is intended primarily for lab use. It’s priced at about $7,500 (4999 euro) including an embedded PC.

Before it's here, it's on the Bloomberg Terminal.
