NEC to Introduce 3D Laptop Next Year? 103

Posted by michael from the eyestrain dept.
Hoon Mihn Fao writes "For those of you for whom 2D laptops are not awesome enough, next year NEC is coming out with a 3D laptop. No, you don't have to wear those retro red and blue glasses, but the monitor is actually an LCD screen placed on top of a conventional monitor. The company is currently seeking gaming software companies to produce games for its technology. Each unit will cost an estimated $200 more than a conventional laptop."

    NEC Corp. plans to market a laptop computer next year that can display 3-D images without requiring special glasses... The new laptop will feature a special liquid crystal display panel that is placed on top of a conventional screen. Users will be able to view digital photos of [sic] play online games with the 3-D image display or use the standard panel for viewing Web sites, Nikkei said. ... Mercury3D, a software company in Chiba Prefecture, Japan, will also provide a program that converts standard 2-D images to 3-D on the new laptop, Nikkei said.

    How is this supposed to work? No glasses, a special LCD on top of a standard monitor. How do we get actual or simulated 3D out of this? If it doesn't provide two different perspectives to each eye (as shutter glasses do), presumably the LCD must project the 3D image into midair. And how does the software generate 3D from a 2D image? There isn't enough data in the source image to do this properly. I'm betting vaporware here.

    Anyone have an insight?

      The very fact that your eyes are not in the same place generates a different perspective for each.

      The LCD screen can block a different part of the image for each eye. (try holding your finger in front of your face and close each eye in turn)

      I dunno the exact method used.. but found this on my fav dutch hardware site : "The monitor contains two TFT panels separated by a parallax barrier, which directs pixel images to two separate regions so that each eye receives a slightly different image. In the end, the brain formulates the signals so that the image appears to be a three-dimensional object, Nakagawa said." So it seems that it is possible to project 2 slightly different images to both eyes without shutterglasses.

      I read the original japanese nikkei article [nikkei.co.jp]. Looks like the special LCD is not on ``top'' of the regular monitor, but ``over,'' or covering the first one. I assume that those two screens can produce slightly different images producing 3D illusion.

        Basically, this is correct. Here in Japan, Sharp (at least) has been doing these for a while; my current keitai even has one! I don't know the grisly details offhand, but from what I can tell, there are two layers, each of which are angled towards one of the two eyes; displaying stereoscopic images, one eye's worth on each layer then gives you essentially the same result as those old red+blue+purple displays with the red-and-blue glasses. It's certainly not perfect, but it's an acceptable imitation.
        • Question: So does this present a problem if you:
          • Lean too far to one side?
          • Move your head too close or too far away from the screen?
          • Rotate your head from left to right, effectively moving your right eye back and left eye forward, or vice versa?

          I'm curious to see how well this works if you're not seated in ideal conditions, which is the premise behind the moniker "laptop."

      I've seen these before. The interesting thing is that they are putting them on laptops.

      It works by having 1 standard LCD monitors and one special LCD monitor, one on top of the other. The top one is designed so that the color white shows up as transparent. You need a video card capable of driving two monitors at once, and to take advantage of the effect, you will need software that knows how to display each image. The slight difference in distance between them can make for some interesting 3D displays because your can tell that it really is overlapping.

      Mouse control is a little weird because you have to tell the computer your using top monitor or bottom monitor since they are more or less dual displays. Once software knows how to handle this hardware that could be fixed.

      The projected use I saw was using Maya with your controls on the back monitor and your 3D rendered creation showing up on the "front" monitor, rendered in real time. That was a stand alone monitor, but I'm guessing it's the same technology.

      There is a company that sells desktop LCD monitors for this right now. See http://www.deepvideo.com/ [deepvideo.com]
    • Having used 3D monitors before with LCD glasses, I imagine the LCD panel is simply synced to the monitor frequency, shunting each frame left and right. So you want a really, really high frame rate to keep flicker to a minimum (because you are halving it). If my guess is correct, only the size of the LCD panel and Monitor need line up, not the pixel density, however, there are probably distortion effects from pixel misalignment, like resizing your resolution on LCD displays.

If you have a 3D capable display that doesn't require glasses, you can add infrared tracking that Holotouch [slashdot.org] invented and you can suddenly track control objects with hands in 3D. Imagine being able to drag and drop or draw on the virtual screen (that floats in front of the actual screen) with your fingers. That's pretty cool and has a lot of applications in every area.

    next year NEC is coming out with a 3D laptop.

    As far as I can see, my laptop has height, width and depth. So it's 3D, right? Does that mean that we can expect thicker laptops in the future (that are of course more 3D than thin ultra portables we can see today?)

    actually an LCD screen placed on top of a conventional monitor.

    This is a really clever idea. Now I can see how they managed to get that real 3D feel. Using a conventional CRT monitor in a laptop certainly adds some third dimension.

    Now I can see what they are planning to do:

    1. Use CRT monitor in a laptop
    2. CRT monitors are cheaper than LCD panels, but laptop with CRT is more 3D, so it can be more expensive than conventional thin ones
    3. ...
    4. PROFIT!! :)

    Remember those little stickers, covered with ridges, where you turn them and watch the image change to one of 5 or 6 possibilities? If a computer screen is covered with verticle ridges, you could control the flow of light to left and right eye from limited viewing angles.

    Such a monitor would only work if the person's head was in certain positions.

    Other technologies are possible which would allow the viewer to be in any position and orientation. Think tiny lenses instead of long ridges.
