MIT Develops Inexpensive Transparent Display Using Nanoparticles
rtoz writes "Researchers at MIT have come up with an innovative approach to creating transparent displays inexpensively, while providing wide viewing angles and scalability to large sizes. To create the transparent display, silver nanoparticles are embedded in plastic, tuned to scatter only certain wavelengths of light and to allow all other wavelengths through. In this example (video), it is tuned to scatter only blue color using 60nm silver particles. The researchers believe that it can be easily enhanced to a multicolor display by creating nanoparticles that can scatter other primary colors. The ability to display graphics and texts on an inexpensive transparent screen could enable many useful applications. For example, they could bring navigation data to windshields of cars and aircraft, and advertisements to the sides of skyscrapers. Cheap 'stick-on screens' could be developed using this technology. The messages broadcast on nanoparticle screens are accessible from virtually every angle. Transparent screens themselves are not new; for example, Google is working on Google glass. But they are expensive. This MIT invention will help to produce transparent displays easily and inexpensively."
Eh, I can see the most loathsome terrible people in the universe getting a little ad-revenue out of store windows.
Blue screen of death will have a whole new meaning if that pops up on your windshield.
If you watch the video (skipping the useless talking parts), you will see that the product demos are in front of a very dark backdrop. When the random hand picks up a MIT mug behind the active elements on the screen, the purple color becomes very washed out by the mild lighting off the mug.
I'm not sure whether this is a raw power problem or a limit of the method they are using, but it needs something more before it can even work in a dimly lit room. If they get it to work under standard fluorescent office-lighting, it'll have some use. If they get it to work under the fierce glow of a gravitofusion reactor, then I could believe the car-HUD claim in the summary.
The amount of silver in this is likely to be extremely small. They're nanoparticles for a reason. I doubt this'd stop adoption; a problem with scaling production is much more likely.
Captain, I must have some platinum. A small block would be sufficient, five or six pounds.
All high-rises will become huge billboards. Shades of our future Blade Runner aesthetic.
Huh. Loathsome and terrible? A store window seems like the perfect place to be selling things. People have been putting animated advertisements in them for decades. That being said, this seems a rather expensive way to do it. Glass is much cheaper to replace.

I'm sick of people coming up with these inventions that use some form of exotic material. Silver, gold, palladium, rhodium ... for God's sake, use something that is not an investment grade metal.
Considering the prices people pay for electronics, the raw materials are a tiny fraction of the cost. The quantities of these metals is likely no more than you're already getting in your $300 Samsung 27 inch monitor.
I for one would pay extra for something much cooler than ordinary LED, especially if I could stack them and get some cool 3D effect out of it. :P

and I will never buy your product again. Hell if I'm in an accident due to your advertisement and I survive, I'll sue you into oblivion and guess what, Your insurance company is not going to cover you.
One thing this tech may be used for is improving vehicle safety by providing a better HUD (heads up display) for things like a NiR (near infrared) and UV camera that allows me to see the fucktard driving w their headlamps off just after sunset because he thinks he don't need them.
How about seeing the damn idiot who's broke down on the shoulder in the fog/rain/snow/night, whatever makes it more difficult to see. These are the kind of uses I can think of that have a great benefit to us if they make it cheap enough to actually be applied as a film - we already do this for safety glass so incorporate it into the safety film. Hell you even have the ability to use it for highway safety information such as "Rt 3 lanes closed 2 miles - Merge Lft".

According to the abstract, this is a projection screen only. They fill a transparent sheet with tuned nanoparticle subpixels, and they project monochrome light onto the subpixels that are tuned to the color of light they want. So, it still requires an external monochrome image projector with at least three times the resolution of the "transparent display". It'd be simpler to just fill a transparent sheet with *regular* silver particles and use a *regular* color projector. The science is cool but - as usual - impractical for this particular use
...is as a projector screen that is only reflective at one very specific wavelength. It doesn't emit any light...there are no pixels...nothing about it changes what parts light up.
It's still quite novel...i'm not sure why they couldn't be more specific (or less misleading?) in describing it.
Keep in mind it's not totally transparent - see how the table looks yellow behind it? Add red and greed and you're going to reduce the incoming light further. They said it can be tuned...so could be changed to avoid any of the peaks in LED, CFL, and daylight. Will be interesting to see where this goes...but if they start painting cars and buildings with this it's going to do odd things to the incoming light.
You can get rich if you own a politician, but you have to be rich to buy one in the first place.
I'm curious if this can display black. One big problem with AR glass displays is drawing the color black. This could be a big a pretty big deal for AR glasses!

It reminds me of something you'd see in a 70's or early 80's British scifi TV show, like Doctor Who or Blake's 7. Some sort of plexiglass being used as a monitor.
Be seeing you...

Pretty much all cars that drive off cliffs are flying. Not for long and the landing sucks, but flying none-the-less.

It's a cool demo, and a neat idea, but I keep hoping that the era of projection of images is winding down, with direct displays taking over. Even with advanced aspherical optics and laser projection there's limit to how close you can get to your viewing plane and still have a good display image.
Is it just my observation, or are there way too many stupid people in the world?
Stop being afraid of prices. If silver is $20/oz and one of these displays requires one thousandth of an ounce, then the cost of silver in one is two cents, so who cares?
Go figure out what the actual cost is and then you can figure out whether you need to engineer a suitable replacement 60nm (polar?) nano-organic for mass production.
We have plenty of silver on Earth - my god, you must've been locked in a closet in fear when everybody was running around with semi-disposable silver halite emulsions in their pockets.
My God, it's Full of Source!

Always expensive the first generation is.

That occurred to me to, but I think it is a safe bet that a pane of glass will *always* be cheaper than glass plus nanoparticles plus circuitry and power. That being said, I'm sure there's a point where it'll eventually become cheap enough to make an entire storefront window out of it, and realise some benefit from the visuals over more traditional forms of advertisement.
Assuming storefronts still exist then, and assuming it becomes common to use, I'd move on to the main point. What's the big deal? Store windows basically are nothing *but* advertising...

Stack a bunch of these screens into a cube or sphere to create a volumetric display.
-ubuntu others as you would have others ubuntu you.
To be useful for windshields, I think it would be necessary to allow light in from the outside (into the car) regardless of wavelength. I watched the video but it wasn't clear to me that they could make the reflection only occur on only one side of the surface.

Plus when you watch pr0n, everyone else will be watching too.
But how much cheaper? And is glass plus replacement animated neon sign cheaper than glass plus nano particles plus electronics (which might also include laser tripwires in the glass for alarm systems)? Is the neon sign as versatile as the nano particle glass? The nano particle glass can even be sponsored to pay for itself, and with a capacitive touch screen somewhere on the glass could be used as a store catalog.

Standard mirrors are generally "silvered" with aluminum.
Cool, p0rn while I'm driving.
Bit of historical trivia; when the Spanish arrived in the Americas silver and gold were very close in value to each other. The conquest of Mexico and Peru flooded the market with so much silver that the price dropped to 1/10th that of gold. There are altars in churches in Lima and Cusco (and probably in Mexico) made of half a ton of solid silver.

Well, actually, what they were saying was that the actual display was a sheet of plastic stuck onto the glass. Meaning that you could retro-fit an existing window.
This could be even more interesting if it can be done as in the paperwhite displays, where the image consumes no power while static. You could then easily have your own programmable "stained glass" windows, Not to mention a new approach for automatically-shading windows.
Speaking of paperwhite displays, at least one major retailer has been peppering their stores with fairly sophisticated units, radio-updatable. So I doubt they'd balk at a reasonably-priced transparent display.
I don't see why you got modded down. Guess it's the unforeseen consequences.
CLI paste? paste.pr0.tips!
That is interesting, but doesn't change anything on the point of replacing a vandalised window or cheapness of glass :)
But, yeah, my main point was, I don't get why the parent, way back up there, was so worked up about a store window having advertising. That's what those large front store windows are *for* and even today are often filled with transparent plastic decals, paper posters, store merchandise, TV screens, even animatronics.
And certainly if this comes down in price it could be worth augmenting all the other storefront stuff with. Assuming storefronts still exist :)

Actually, it looks like the background is translucent, not transparent. Also, the foreground looks almost opaque!
I'm working on a real transparent display, where both the background and the foreground are completely transparent.
Where do I get me some of that venture capital?
Have you tried turning it off and on again?
There's probably more silver in the solder inside your LCDTV than there is in this panel. Calm your tits.
Still waiting on Serviscope_minor to wake up to fucking reality and realize that Jessica Price isn't going to fuck him.
If you have an old LCD screen with a burned-out CFL tube, you can pull of the back diffusers and have a fully-transparent LCD display.
Sure there's no self-illumination whatsoever so you need to have it against a bright background (eg a window during the day), the the effect is rather novel.
Most of the power needed to drive monitors is in the backlight, so chances are the power supply will be unnecessary. You'll probably be able to power it from the +12V/5V lines of your computer PSU.
If you're lucky and get a good model you can power the whole thing with just +5V from a USB port!

Only the store and advertiser will be able to determine if it's worth the money to them. Ads aren't cheap now.
