3D LCD's
Sharp has developed a LCD-based technology to give you the perception of 3D without special glasses. They basically take two LCD's and stick one behind the other, with a parallax barrier between them, so that each eye receives a slightly different image and resolves the two into a 3D object. They hope to integrate the technology into both notebooks and flat desktop LCD's.
I wonder if such a technology, long-term, could be useful for Pocket PC's or other PDA's. They'd first have to reduce the side effects of the parallax trick (such as viewing distance), but it might be another way to increase resolution without decreasing the size of the content being presented. Also, would you want a 3D PPC?

Not for me thanks...
I am legally blind in my right eye so I can't get 3D. Those rides at DisneyWorld give me headaches. Cool idea though.

Great idea, but...
This is a great idea, but would 3D images be harder on the eyes and eventually cause a higher chance of eye problems? Sounds cool, but if it will hinder my eyes I would no want it.

We have such great 3D-graphics technology now, (in 2D, I mean) and who uses it? Gamers, artists, and scientists (among other professionals). So really, those would be the market for this technology, too.
If there was a big demand for 3D in handhelds, I think we'd see more advancement already on our Pocket PCs. Then again, if it becomes the norm for desktop users to have it, It'll surely end up in a Pocket PC. The geeks will demand it!

I'm more interested in OLED displays making their way to mobile devices. Thinner form factors...improved battery life...bright screens. Could this be the holy grail we have been striving for? :?:

Toshiba has already showned a prototype laptop with a 3D display that does not require special glasses. Wonder if they are competing technologies?

Well, it sounds awful similar to the 3d glasses technology that shows each eye a different image at a really high rate. If so, I question how useful it'd be since I own a gfx card that supports that and have the glasses. They talk about Quake for example... well, a true 3d look in a FPS is indeed cool to look at, but not very useful.
At first glance, when a crate for example does appear to have depth, it's cool. But when you're trying to run around a map at 60fps, dodge 15 other people trying to kill you, and hide behind said crate... it's much less cool and much more annoying. Sure, it may be semi-3d, but you're looking at this semi-3d world from the outside through a window as it were. It doesn't come out of the screen, just makes the screen seem to have depth. Makes it hard to judge. Of course, all of this is based on the assumption it works like the glasses.

This type of technology is similar to how those 3D stereograms work. There are two things your eyes do when looking at objects. What stereograms typically do is trick your eyes into thinking they're looking at something further (sometimes closer) than the actual picture while the focus length at the distance to the picture.
Now, having said that, viewing stereograms have been known to actually be good for your eyes as they do exercise specific eye muscles that tend to be underused by us computer geeks (especially muscles used in viewing objects at a distance). However, viewing stereograms are normally done a minute or so at a time. I wonder myself what the long-term ramifications could be.

The real world is 3D, you know :roll:
But I most definitely do NOT want a 3D screen. More depth at the cost of visual quality, including MANY 3D artifacts, vertical lines, blankspots. I've got my 3D graphics card and that's more than enough. I don't need gadgets, I need solutions, as that one article read.

Well, the bright side to all of this is it may one day become a solution. I mean, I do a lot of 3d graphics hobby wise... it'd be really cool to have a monitor I could just push a key and instantly be looking at the image with seemingly real depth, then flick back again to normal view. If the technology can be perfected to the point where it blends in seemlessly, I say go for it.
