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."

Does anybody have more info?

the article doesn't really have any technical details, I'm curious to see what principle this screen operates on, and what makes it different technologically from the previous 3d LCD screens we've already seen (I think it's the 2d/3d nature of the screen without loss of resolution, as the article says, but I'd like to know how they get this to work)

The parallax blocker is not switchable; in 2d mode the same image is sent to both fields.

Read closer:

But the main challenge was making it possible to switch between the ordinary 2-D mode and 3-D with the push of a button, while providing the same image resolution in the 2-D mode as in a standard display without 3-D capability.

The parallax blocker, when activated, makes half the pixels in the display visible to the left eye and half visible to the right eye (presumably in vertical stripes, from the available information). When the parallax blocker is turned off, both sets of pixels are visible to both eyes. If you have a display with a resolution of 1024x768 in 2D mode, then it would have a resolution of 512x768 in 3D mode.

Are you sure?

I didn't see any indication in the article that Sharp had developed a 3D LCD. As far as I can tell, Sharp has developed a 3D flat screen.

Mod this up!

Funniest troll I've read in a long time.

Objects are perceived as the same distance away when light takes the same amount of time to traverse from each of the objects.

That's great! Objects appear further away because it takes longer for the light from them to reach my eyes.

Re:Just curious...

[MarcoAtWork]

the whole point of this display from sharp is that the '3d' mode can be switched on on demand and that day to day applications and GUIs will work the same way they always do.

When you're using word etc. you keep the parallax element transparent, and the screen is just a normal 2d LCD display, when you're using 3d studio, playing doom3 etc. you switch it in 3d.

Now, it will be interesting to see if there is going to be more eye strain for people using the 3d mode all day long vs using LCD-shutter-based solutions (with the screen at 160Hz obviously). I don't think so, but you never know...
