DuPont announces Olight OLED displays

"Initial applications for Olight® are expected in consumer, industrial and medical applications. Full color displays with video capability and eventually flexible displays on plastic substrates represent DuPont Displays future product opportunities."

It's not clear to me what advantage it has over existing LCD displays... maybe it's brighter and doesn't need backlighting?...

There's an interesting development kit available here:

http://olight.dupont.com

"The evaluation kit includes a 2.1-inch 128 x 64 Olight display module, USB or parallel PC interface cables, a 120V AC to DC power adapter, and a CD that includes a user's guide, application software and sample images. It is available to select customers for $1,695."

I think they are hoping it will be cheaper to produce and more reliable. Though the LCD production has gotten a lot better, they still produce a lot of dead ones, or ones with so may dead pixels that they are not usable. So there is a lot of overhead there.

The other problem is efficient backlighting, you have to have a really bright ccfl in there, or in smaller applications lots of white LED's to light them up. If the stuff itself would light up then you wouldn't have to waste the power to light the whole thing and the space for all that.

I'm excited about this stuff, I can't wait to wallpaper a new TV onto my wall /ubbthreads/images/graemlins/wink.gif

I wonder how long the organic EL last over the other EL and if there simuler or the same stuff with a diffrint name.

These displays are being made by inkjet technology. I can see a day coming soon where tractor trailers will have giant video screens on each side. The ones you see today with big hamburger ads are done with inkjets. Costs should plummet rapidly.
