Light-Emitting Polymer Displays
BlackSol writes "Yahoo is covering a very cool piece on the development of roll-up screens. Possible uses from home televisions, to tele-watches, and military uses such as real-time satalite fed maps in the field."
Will this open the possibility for 3D tv using multiple transparant layers?
:)
Or perhaps the multi-channel edition where you have a book with 100 pages: every page is another chanel. Nice and convenient during the commecial breaks

Well, as long as it's a touch screen, I'm happy
{and slowly a song from the Who sets in: See me, feel me, touch me...}
I wonder if these can get high enough res. to be useful for laptop/handheld displays? That would sure be handy...

There are many uses for this in areas with political instability. Now instead of having to go through the problem of making new flags and banners every time an area changes hands, you can just have one of these up each flag pole, and just change the image as the situation warrents. I can see applications for this on the west bank / parts of Africa already.
Weave this bad boy into a full body suit, mount micro cameras throughout, project the image seen behind.
Voila! Predator. From twenty feet or so, anyway.
If your bitterest enemies are people who hack the heads off civilians, then I would say you're doing something right.
. . . military uses such as real-time satellite fed maps in the field.
Better make sure those satellite connections are really secure:
"All right, men, the enemy stronghold is dead ahead. Charge!"
[ten minutes later] "Uh, Sarge, we must have gotten turned around somehow, now it's directly behind us."
[fifteen minutes later] "Now it's saying we're in South-Central L.A. Stick together, men."
...for this technology.
Cheap HUDs for autos (Heads Up Display) and bike helmets is an obvious application.
Televisions everywhere. (Okay, this could really suck; who wants to see ads for Cheer everywhere you go.)
And the big one: Wrap-around, full vision wearble displays. Granted, I'm stretching here, but one can dream, eh?
If this technology really works well, it could solve a great many problems associated with computer displays (size, heat generation, cost, etc.)
Lot's of really cool technology coming soon, makes the current despond somewhat more tolerable.
Everything in the Universe sucks: It's the law!
Imagine seeing a cityscape where every inch of every skyscraper is a billboard. Sound far-fetched? Read the article -- this is about printing televisions. These things are going to be cheap. Look at the end result of a technology such as the printing press becoming widely available -- we now have reams of printed matter everywhere we look. An active display technology that is so convenient to use and cheap to produce has just as much potential, if not more, for becoming pervasive and used everywhere.
I think the biggest question for widespread use of these things, on a commodity level rather than an appliance level (toilet paper, not PDAs), is power. I don't think anything on the market today is truly a satisfactory answer to the question of how to power ubiquitous flexible displays like these, but we're close. See a very recent slashdot post (no link, so lazy...) about flexible solar cells being developed. Also, there is an incredible push for greatly improved battery technology, and great steps are being made there.
Ultimately, there will be two kinds of uses for this technology. The first one we'll see will be the sort that is more or less permanently installed, and can therefore be plugged into the wall all or some of the time. Even the skyscraper-as-television fits into this category. But at some point you'll need batteries or solar cells or some other power source (some wacky nanotech?) to power more "disposable" applications like animated handbills, greeting cards, movie posters, etc.
End result: advertising is about to get a lot more annoying. Let's just hope they haven't got paper-thin speakers to go with this.

I doubt that a roll-up tv screen or monitor will ever be practical. Firstly, every pixel will have to be driven and that requires an electical connection. A 1024 X 768 will require atleast 786,433 electical contections, and wires made of metal. I expect serious problems with metal-fatigue induced conductor fractures, for roll-up displays. I'll admit that the ribbon cable inside a printer goes through a lot but it doesn't have a quarter of a million conductors either.
This has a lot of cool potential applications, but roll-up displayed will not be marketable

I think I'd like one of a Penguin stomping on MS HQ...
Better still, if the material could be made thin enough and safe to implant under the skin you could have animated tattoos you could reprogram at will.
(I'd go for a penguin stomping on MS HQ again)

One of the other pretty cool technologies being developed by the guys at Plastic Logic (a spin off company created by the same people from Cambridge University who formed CDT) is the ability to create full electronic devices by using an inkjet printer loaded with a cartridge of these conductive polymers. It would be pretty cool to be able to see a useful device on a web page, download the circuit, print it out of your inkjet and then have the working device straight away.
I can't seem to find anything about what kind of refresh speeds they can get from this, or energy consumption. Has anyone seen any current figures released by these people?
Regardless of how cool this could be, it'll be a dud unless it makes laptops last longer and has at least equal moving image quality compared with LCD screens.

I've been dreaming of my ultimate portable for some time, and this - roll-up screens - was all that was missing. I have a roll-up waterproof keyboard that works quite well. Imagine the guts of a notebook PC (no CD, keyboard, screen), a kind of brick the size of a stack of CDs. Fits into your pocket. You can add a flat battery underneath for portable use. You can plug in a roll-up screen and keyboard when you're on the road. At the office you dock it into your main notebook or desktop - synchronizing all your data, updating your email, etc.

It's not just the individual pixels which are made with polymers. It's the individual traces also. In fact, the whole field of polymer semiconducters is starting to ripen and bear fruit. The sheets of plastic they print won't only have light emitting portions, it can include power traces and even decoding logic! There might be a copper ribbon cable to connect the entire display to whatever external source provides data and power. But the entire display will be made from polymers.
This really is amazing technology. The circuitry is basically printed out using ink jet style heads. Actually, one of the article says that it actually plots the traces out ala a good old fasioned plotter as opposed to line-by-line like a printer. It's not hard to imagine that this stuff will lead to a rebirth of the homebrew electronics hobbyist. Even if you couldn't afford to buy your own plotter, a prototyping shop which owned one should be able to produce custom circuits to your own design in an extremely fast and cheap manner. Imagine a semi-conductor Kinkos! Could be cool stuff.
Most of the posts here assume plastic = transparent. Yeah, that would be nice. But it's not necessarily the case here. Nothing in the article suggests that this display is transparent.

A number of the comments here about advertising and the proliferation of displays reminded me of Minority Report. Everywhere the characters went were advertising displays - wrapped around the walls of stores and malls, moving billboards, even animated cereal boxes (John Anderton angrily tosses one aside after being bothered by the distraction at one point). Obviously Spielberg has the same vision of the future as many of you.

I want to be able to go into a store and say 'I'd like a screen 120" wide by 67" tall', and have them print it for me there on the spot, laminate it together, then just sell me a little re-usable "connection" module that clips on the edge of the screen to power/activate it.
If you want a different size screen, you just toss out the old one, keep the module and get a new one printed up.
And it's starting to sound very, very possible...

Speaking of such things, imagine if someone hacked in to your t-shirt. How long would it take before someone told you that you had goatse dot cx on your back?

I've read a number of articles on these and other flat, flexible displays such as "digital paper". It's amusing that all of this life-changing display technology is just months from everyday use... and has been for the past six or seven years.

I'd love to buy a roll of TV, change the channel to WB, and then use it as TP.
Who knows? that could displace Nielson ratings!
Why would I want a roll-up TV screen? Ever since I moved my 4 computers out of my living room and into the second bedroom, my living room has appeared empty. Now I'm supposed to roll-up my TV when I'm done watching? Maybe if it's on remote control, but otherwise, forget it. I like it the way it is.
I like the "Maps in the field" kinda thing, though. Kinda like Red Planet.
It's kinda cool watching some things from Sci-Fi come to reality. I just wish they'd get working on the damn holodeck. Talk about the ultimate in addictions. I'd never leave.
Change the appearance of large items at will - make your house 'look' scary on Halloween, Waving flags and fireworks on the 4th. Give your house a stone wall, garden, or 'trees'. Make your house 'transparent' or 'invisible' for parties, exhibitionism or to get 'away'! (Screens on both inside and coutside of course.) Change 'wallpaper' at whim, decorate by era, place, or fetish. Make your apartment look like its huge! Play a 'real' game of quake, or nethack!
Your car could be a different color every day, or adapt 'styling features' (camo trucks for hunters or the army) 'fake' turbo for all the Rice-Boys out there.
Put 'windows' to the outside world or made up world in your office or cube. Your 'desktop' could be your desktop! Video conferencing could be far more personal, and body language would become useful.
A VR Holodeck of sorts could be be possible, embed into all surfaces in a room.
One *real book - any book contained within!
Graffitti could become an accepted artform. Leave it there a week and then *poof*
Learn to dance with the 'magic' footprints appearing at the proper times and positions.
The Hoover dam could be the biggest theater in the world!
Of course, by the time this comes to pass, the **AAs will probably have legislated that a user cannot view these screens without pervasive advertising. The Hoover dam will play McDonalds and Disney commercials 7 out of 8 hours, some 'Avatar' will follow you around offering product suggestions every two minutes, and someone will get pissed at you for something and hack your house, car and t-shirt to show goatse.cx at random intervals.
Don't want to think about that on the Hoover dam
What a cracker target that would be for defacing.
Or for stealing. There isn't much use for the LED scrolling banner thingies at home, nor is stealing one of the jumbotron type things in Times Square an option. However, if they have these things everywhere, small poster-sized ones would work nice as a TV at home and wouldn't last too long on the streets.
I'd say that for a billboard, they will use smaller polymer displays which will be cheaper to make than one mondo 24'x32' display. Say 48 -4'x4' screens. Now, there's a tempting target- you might not have much use for a 24'x32' screen, but all those smaller screens, think what you could do with them?

Now you go and take this stuff and combine it with the See-Through, Paper-Thin Speakers and you've got your media where ever you go.
Just makes me wonder how long it's going to be until movies are made from a central perspective, like IMAX in your home.
At the very least it should be a cheaper method for bringing those remaining 34,940 movie theatres into the digital age
