Light Emitting Pictures On Standard Inkjet Printer
CrashRide writes: "This story on FOX states that UofA scientists have discovered a way to print light-emitting pictures on thin sheets of plastic using a standard inkjet printer. Fold up pocket monitors?" The article says that these scientists have produced "OLEDs of simple bands of light, a scorpion, the University of Arizona logo and even photographs of themselves."
reading comic books under the sheets at night a lot easier :)

This is the Gilette model: "Give 'em razors, charge for blades!"
"Flyin' in just a sweet place,
Never been known to fail..."
that pr0n can't benefit from?
It says "cheap".
Could industries like bookmakers or publishers use this sort of thing? I'm rather fond of the glowing text on the black background, if you ask me, and it would provide a great alternative to something like a reading light. of course, it'll probably jack the cost of books up. Even though they do claim it'll be "inexpensive".
However, I do think their assumption about 'computer monitors' is silly - right now, they're printing flat pictures, not moving, highly detailed ones.

"Why didn't you print out another copy?"
"It ate my monitor too..."
I'm a bloodsucking fiend! Look at my outfit!
This is just a poster that glows -- it's a static picture that glows using a low amount of electricity. Unless you're running Windows, and all you need to display is the same bsod, you'll need a more "dynamic" display :).
Never underestimate the bandwidth of a 747 filled with CD-ROMs.
Does that mean the Mozilla team doesn't have to fix bug 2586, "Print Preview animates GIFs"? Here's the original bug report:
In Print Preview, animated GIFs are still animated. I would love to say
that it is not a bug, but unless the printing code can then back the
preview up by animating the printed copy, I suggest the Print Preview
should show a static image.
This also applies to applets, Javascript, "hover" and "active" pseudo
classes, and so on.
The shareholder is always right.
I first saw this on a Sunday afternoon techie program, think about text flying around, blinking or being added dynamically via a wireless lan connection to a page and you've got the idea of it's coolness (even though its only monochrome).
The thing I like about eInk the most is that its fairly high-res (well, it looks sharp to me) and that it does not require back-lighting, it reads like paper under natural light.

There is a better story on the UA newspaper. And here is the link to research department. Not much here yet except for an animation.

If you can print conducting traces, you could set up a grid pattern of traces around pixels that would let you selectively activate pixels, much as you do in a passive-matrix LED. At any given time, one horizontal line (say) would be ground, and the rest would be at Vdd. Vertical lines would be driven or not driven depending on whether you want pixels in the active line on or off. If these printed pixels really are OLEDs - diodes - then you won't have to worry about the other horizontal traces shorting across the vertical lines.
I'm sure there are a number of ways of printing conducting traces with ink. Even a high-resistance trace could be electroplated after printing with thicker metal.
The only question is whether a) the type of OLEDs printed with this technology are really diodes, passing current only in one direction, and 2) whether instantaneous current can be high enough to give an acceptable _average_ current (and brightness) per row over the whole scanning cycle. A row turned on one thousandth of the time needs to be a thousand times as bright when it's on.
Other methods of addressing pixels in a display are of course possible. This is just one of the easiest (not necessarily best).
Not trusting the headline whores at fox news, I did a little searching on google and found this article published in June of 2000. It has a better review of the actually technology from a pure science point of view, rather than the "marketing press release as if it were a product" garbage that was posted.
"Get them before they get....
Ultimately, the technology could lead to computer monitors that you fold up and put in your pocket like a handkerchief.
when you accidently blow your nose with it?
Thanks to file sharing, I purchase more CDs
Thanks to the RIAA, I buy them used...
does this mean that they can be wired back to back to create spray on transistors? Ultracheap custom chips
Spray on transistors are almost there. (The linked article mentions some spray on circuitry but the (fast) transistors are rubber-stamped, they're still working on spraying those). The folks described here are doing spray-on polymer transistors.
Hmm, couple the LEDs, the transistors and some good optical sensors and you can make yourself a cloak of invisibility...

I'm trying to teach myself to set people on fire with my mind... Is it hot in here?
This was done in June of 2000 by Epson-Sieko (yes the printer people) and CDT, a British company that researches OLEDs and similar crap.
Google brings up some resulst verifiying this but unfortunately the real copies are down - heres what google has cached.
The prototype colour display has been made using CDTâs red, green and blue polymer materials and an industry first ink-jet printing process developed for the project.
Rather than illumination, they use electrified pigments or rotaing, embedded spheres to change the color of a sheet of plastic. One difference with the technology at UoA is that charge is only needed to change the image, not maintain it. One of the developers described it as "paper that prints itself," which gives you an idea of what kind of applications it could be used for (e.g. hourly updated price signs=good. Monitor to watch a live video stream=bad).
"Prepare for the worst - hope for the best."
This is a completely blatant plug, but it is on topic. There is an EL technology that allows for a paper-thin cold light source. The first one we have produced is a "Linux" lamp. I have video of one on our web site http://www.exoticlights.com The lamp not only glows but also is animated. We have a few prototype units for sale.
When I was a graduate student at UCLA in 1998, I heard of Professor their that already patented the process for using ink-jet printing techology for creating Organic LED devices. The original paper is: S.C. Chang, J. Bharathan, and Y. Yang; "Dual-color polymer LEDs processed by hybrid inkjet printing technology", Appl. Phys. Lett., 73, 2561, (1998). If you want to know more about this, visit Dr Yang's website at http://www.seas.ucla.edu/ms/faculty1/yang-yang.htm l.
And most importantly, it'll look like those cool futuristic movies from the 1960s!
