3D LCD Display
Powerdog writes "After 10 years of lab work, Sharp has developed a 3D LCD display that works without glasses. They expect to use the displays in games at first, and expand into PCs and TVs. Production begins in a few months and products using them should be shipping in early 2003. Naturally, I just bought two 2D LCD displays for my home office two weeks ago."
Double D's are more than enough on my LCD screen, thank you.

When you actually *make* something, it's not a mystery business plan. You say, wittily:
1. Create 3D LCD that works without glasses.
2. ???
3. Profit!!!
In this case, ??? can be expressed as:
"Sell 3D LCD for more than it cost to manufacture it."
Okay?
The P.R. Gives some indication of how it works:
Here it is at Sharp's site

I applaud Sharp's achievements in this exciting area of optical technology, but if the display only works without glasses, this eliminates a good percentage of computer users who, like myself, have to wear glasses.

WRONG.
That would only work if you were able to know when the light being reflected from said objects originated. Given that light, in most cases, is a constant element (it's not frequently changing, i.e. stopping and starting, like a strobe), and given that you are not the originator of the light and you have no way of being sure which received photon (or group thereof) is (are) supposed to be synchronous in origin/reflection with which other photon, your explanation for depth perception/3D vision is not possible. 3-D vision actually relies on a number of processing tricks in the brain. You do the footwork, but the most commonly cited ones are: motion parallax, relative size, occlusion and binocular disparity.
Active sonar works the way you describe, as does radar. Human vision does not. Think of it in terms of active vs. passive processes. An active system is one that originates some signal and meters the response. A passive system makes sense of the existing signals whose origins/timings are not often known. Human vision is a passive system...
by reading a post later (which is the original press release) it is clear that there is a 50% loss of resolution in the horizontal axis.
The press release on yahoo says that this 2d/3d display has the same resolution as a 2d-only display, not that in 2d and 3d it has the same resolution (which I thought I saw when reading it the first time)
Basically this display works the same as the 'older' 3d LCDs when 3d, but the parallax blocker is not physical, it's switchable, so the screen can be flipped to 2d when needed and not forcibly left in 3d like the others.

i will go with a volumetric display any day of the week.

I'll actually be impressed when I can walk around the image and see different angles.

I have a 3D LCD display at home that works great with or without glasses.
Now what would really be cool, is a 2D LCD display... I mean, sure they're already pretty thin.....
oh wait.... I'm supposed to read the article first, aren't I?
I'll have something intelligent to add one of these days...

2 x 2D = 4D
4D > 3D
