MIT Develops Quantum-Dot OLEDs
deglr6328 writes "Researchers at MIT have developed a new type of Organic Light emitting Diode (OLED) using Cadmium Selenium Quantum Dots as the electron-hole recombination layer. It is widely believed that the next generation of flexible flat panel display technologies will be self luminous (non-backlit) organic light emitting diodes. However, the efficiency and lifespan of both small molecule and polymer type OLEDs, to date, has been poor for small wavelength emitting compounds. Using quantum dots as the emissive layer in OLEDs potentially solves both of these problems since they are inorganic and won't degrade, and they have a theoretical maximum quantum efficiency of near 100%. Mmmmm ... can't wait to buy my first roll-up display!"
They need a new acronym I think. . .
.
But No! It's better to conform to existing buzzwords to be correct. .
Aaargh.

Given this is quantum physics, perhaps this is an example of the uncertainty principle? Inquiring minds want to know...
This is fantastic. In 5 years I'll be able to pin up my TV with thumb tacks right next to my tattered SG poster. This opens up a whole new relm of potential practical jokes for people who don't know it's a display. ;)
now you too can be a walking billboard! imagine 2000x6000 pixel ads right on your tshirt!
the more i hear, the less i believe. show me or screw it.

* back to nature
* obtained from living things
... but then it turned out I didn't care, as long as I get hi-resolution gaming. -theGreater.
Yes, LCD's are easier on the eyes...but working all the time in front of a screen seems to change my skin color to a pale green'ish.
I want to get sunburn when I code!
UVOLED anyone?...please....
You wouldn't know whether it's organic or not until you opened the box.
but imagine if your "smart" BDUs have a software error and suddenly give you a full body "blue screen of death!"
Does this mean that each pixel would be so quantom sized? What sort of graphics card would be needed to drive something like that for a 15" display?!
I wonder what - except from electric power - systems will consume in the near future. I try to feed my notebook bread and cheese, but it doesn't seem to be very fond of it.
Or... organic. What kind of life are we talking here? Do they kill animals to create these displays? Damn, I know some people think it's stupid, but I'm a vegetarian.

This is like the episode of star trek where picard and some scientist debate if Data is a lifeform or not.
Apparently these displays would have a short lifespan. We would then have disposable screens.
You mean we would read information off of a layer of thin, flexible material, only to end up throwing it away a short while later?
Nah... it'll never happen.
I have several ideas with what I would like to do with this technology.
FIRST: make an invisible suit...you know the old deal with the cameras displaying the stuff on you so you look like your background or at least enough like it to blend in
SECOND: make an invisible *james bond* car
THIRD: make an invisible *harry potter* cloak
FOURTH: make my ceiling display some high quality pron for those kinky nights.
*Bows*

Let's replace lead-based CRTs with Cadmium-based displays and call it "organic". So cheap they'll become disposable.
crap, now they have to figure out something else to use all those damn recycled cadmium batteries for.

Darn it, I mistook my ultra-cool roll-up display with Mars background image for a Strawberry Fruit Roll-up! Now my stomach is trying to connect to Windows Update and I don't feel very good...

For example, holographic storage has been 5 years away for the last 20 years. All that data that you currently store on inconvenient and fragile spinning magnetic platters will instead be stored in some kind of tiny crystal with no moving parts except laser read/write heads.
If you want to see some of these things in your lifetime, you're going to need some pretty advanced life extension technology. Luckily, I hear that's just around the corner -- oh wait...
Damn, I thought you were going to say that maybe these screens would make it possible for me to wake up and find Sharon Stone in a workout outfit in my house...
"It is widely believed that the next generation of flexible flat panel display technologies will be self luminous (non-backlit) organic light emitting diodes."
That's good to hear. IMHO, backlit light-emitting diodes were overkill in the lumens department.
... the next generation of flexible flat panel display technologies ...
... where was the first generation of these?
I realize I've been on a bender since New Year's Eve, but
The only flexible flat panel I've ever seen was this palmpilot my friend sat down on, 'tho I really doubt it qualified as a display technology after he crushed it.
Actually I think they are torturing baby cameleons to change color.
