I think one thing they are trying to improve now before mass production is to improve their life span. Right now they die after a couple thousand hours or something like that.
You can buy yours from Kodak today. I think Sanyo is building them but Samsung (Apple supplier) and NEC are now licenced to manufacture the technology. They are sampling at MUCH higher than PDA sized screens, but you can only get your hands on the 2.2, 2.4 or 2.16" displays for now.
<strong>Whatever happened to this technology? Are there any sharp, bright 37'' Super Cinema Displays that use very little electricity in the works? :cool:
The technology is still in the works. You can see them in some places like expensive car stereo screens. Eventually, they'll make their ways up to PDAs and portable TVs. You'll notice when they get that far.
The first screens were just a few pixels. When you get bigger than that, you have yield (percent of pixels that work) and lifetime problems. As those problems are overcome for a given size, the door opens to take a look at bigger sizes. Maybe there will be a breakthrough some day and suddenly you'll see 34" HDTV sets based on the technology, but chances are that you'll see them pass through the iBook/Vaio market and PowerBook/Thinkpad laptops on their way by.
When they arrive, you'll know them as the screens that appear to be LCD, but their dark to light contrast will be better, colors will be brighter and likely more uniform, battery life might prolong some, and ghosting will be a thing of the past.
just a reminder, 20,000 hours is 2.2 years of non stop use (24/7). Not too shabby considering that people don't generally use their monitors 24/7 and 3-4 years out of a monitor is not as bad as it may seem...
OLED lifespans can range anywhere from 10,000 to 40,000 hours, but only for a few components. The problem is that diffrent color LEDs degrade at different rates, so a full color screen would last only about 5,000 hours.

correct me if i am wrong, but the other big advantage to oled is that since each led generates its own light, you get a perfectly even distribution of light across the entire screen, as opposed to most standard lcd displays, which have a backlight along one side (my pismo's is along the bottom), where the color can be washed-out by comparison (which, lemme tell ya, makes it a real pain in the arse to adjust for work).

Not really. Since every pixel is a little light source, production differences make for a different brightnes very easily whereas in TFTs, there is only one backlight.
I know this sounds outlandish, but I've heard every little pixel is an animal of some sort that changes color when subjected to different levels of electricity. That is where the Organic comes from. If so that is some pretty amazing stuff!

Hehe, not quite. It's just made out of carbon compounds. That's what "organic chemistry" means.

If that was true, I would suggest sending larges amounts of energy through Steve Balmer until he turns blue, green, or red

I think blue goes first
wow, that was one sentence. sheesh.

i'm still waiting for the CPU case that's encased in an oled that pusles with my iTunes.
even black and white would totally rule.
