3D LCD's for Sale

Hollinger writes "Dimension Technologies, Inc. has created and is selling LCD displays that yield true 3D images without tracking hardware. 'No Glasses. No Headtrackers. No Eyestrain. No Compromise. No Kidding,' according to their Web site. " I'll believe it when I see it, but can you imagine playing Everquest or something on this thing?

Re:Refresh rates + techniques

[fingal]

They say on their products page that they are using a 60Hz refresh rate which is using "LCD technology, which is inherently flicker-free".

Apparently the revie w in Machine Design says that "The screen uses a liquid-crystal display and an illumination plate. The LCD generates translucent colors while the plate carries light lines or pencil-thin light generators that run the height of the unit and are spaced on a two-pixel pitch. The plate also holds lenticular lenses that direct light at a slight angle. The LCDs are wired so that every other column displays image information intended for a viewer's left eye and the other columns for the right. In the current design, both halves of a stereo pair are displayed simultaneously. Several people can view stereo images at once.".

This sort of makes more sense if you see the diagrams on the page, but I would have thought that it would require you to be pretty much directly in front of the screen and viewing it at a perpendicular angle, (from a certain distance) otherwise you are going to start receiving the wrong information to each eye.

However, once you have it calibrated for your eye seperation, I see no reason why you shouldn't get really strong stereoscopic images. When's the next trade show near Brussels so I can try it out?

Interesting side point: The press on this form of 3d vision on their web site dates back to 1994 so it's not exactly cutting edge (unless they've recently undergone a quantum leap forwards and I haven't picked up on this from the site).
