Multi-layer LCD Displays
Jmo writes "Puredepth has started to produce multi-layer LCD displays. They manipulate LCD technology so that one screen can be placed behind another for actual depth. This technology has not even come close to being fully taken advantage of but it is still very interesting and has many implications for the future. Their main product right now is a seventeen inch monitor, the MLD-3000. It is mainly targeted at medical and business fields but it could be used all over."
I think is a very god piece of hardware but at that price ($1,799.00), i think that a few years will have to pass until we`ll start using it at home.
Think like a hacker, act like a hacker, but never become a hacker !
I've been wanting to purchase an LCD, but I've been waiting for one to be as big and bulky as a CRT.
"It could be used all over."
Like pr0n right?
Come on, some one was going to say it.
The preceding message was based on actual events. Only the names, locations and events have been changed.
Well, I'm sure this will be discussed in much more detail on Monday when the dupe will be posted.
However, I do see a use in this for GIS applications. You can redefine the term overlay with this.

as too all this research and product development into 3D displays. It didnt work in the cinema and personally I cant think of a compelling mainstream requirement for 3D on the desktop.
Do not try to read the dupe, thats impossible. Instead, only try to realize the truth
What truth?
There is no dupe
If you have something that can be separated into near field and far field, the images could be very realistic. I have trouble imagining how this would work with a medical image. Remember the anatomy drawings with a series of plastic overlays.
The stuff I like the best is some mechanical drawings with cutaway views. A good illustrator can totally convey a 3-d structure. I guess what I am saying is that the answer may be a little more cleverness with conventional 2-d displays. The use of user-controlled transparency might do a better job of conveying the information.
Is anyone still working on holographic displays?
Wasting two full LCD displays on getting two blurry discrete depths is not a good use of hardware. If you expend the same amount of effort on a true 3D display, you can do the same thing, and you can actually look at arbitrary 3D objects/scenes.
The practical applications that Puredepth advertises for its MLD displays are vast and far-reaching. In any application that would benefit from greater information density (such as backgrounds with changing overlays, work areas with tool palettes, etc.), the MLD adds true depth to what would usually be a simulated effect. The effect is truly amazing, especially when compared with a standard 2D display.
As you can see, this device is a GREAT benefit to the vast and far-reaching applications that would benefit from it. We could name them, but we'll settle for describing them abstractly. Suppose you have an application where you need to stack crap on top of other crap so that you can't read any of it. Well, this device is exactly what you need!
Seriously, take a look at the screenshot of this thing running:
Stacking crap so you can't read it
In that pic, you can read everything, but it is clear that if you use your computer for things like text, this would be a nearly unusable monitor.
I love the article's conclusion:
Also, the technology, once refined, could be applied to displays with many layers, allowing for even more complex three-dimensional diagrams, such as skyscraper floor-plans, or "data clouds" with more than merely two levels within the depth hierarchy.[Poster's note: HOLY CRAP A 3D DISPLAY? THAT WOULD CHANGE THE WORLD IF it wasn't 25 years old.] Yet another possibility would be to juxtapose two or more different display formats in the same manner. Using a combination of standard LCD displays with super-bright OLED displays might lead to some interesting effects, making the distinguishing factors between layers consist of more factors than merely depth.
As innovators, I tip my hat to Puredepth, and I truly hope to see more products from them in the future.
by Philips uses more conventional technology. You just interleave the pixels of the alternate views.
Hmm, I think I will file this story under:
"Sounds Cool"
subfolder "Probably Useless"
subfolder "What Moron Thought We Needed This?"
Thanks!
this could be interesting if the depth between the 2 displays was enough so you could "switch" between them by refocussing your eyes, like wathing through a fence.
10 ?"Hello World" life was simple then
However the article says: "Several quirks related to the product's design make it somewhat impractical for generalized use."
Slashdot has reached a new level of article posting. Now the poster doesn't have to RTFA anymore.
Why is it news when another company jumps on the 3D using parallax bandwagon?
Sharp has done it, Toshiba has done it. All three are using the same layered LCD technology. Slashdot has covered each one now

Seems like most of the naysayers are just assuming you'd use this screen to simply overleave two 2D displays.
This is linear thinking- sort of like assuming that the powerful GPUs in video cards would only ever be used to render chrome spheres floating over checkerboard floors. Instead, different, more clever uses (like Quartz and Core Image) have emerged for that seemingly extravagant and surplus capability.
Similarly, I fell like somthing like this will be used to add an intangible quality to the dry 2d display- 'life' or 'vibrance.'
Imagine two displays that render the exact same image, except in the areas where it's tracking your eyes or mouse, the images are more in phase while the rest of the screen goes out of phase.
It could literally help focus your attention on the important info, where today's screens are limited to color, 'boldness' and opacity.
I think we won't see the real usefluness of this until it's had time for creative people to tinker with working examples of it, which is the case for most technology, really.
