OLED displays? Screw it: OLED backlights instead.
Researchers focus on efficient flat light source
The difficulty in developing long-lasting, high resolution OLED displays themselves has manifested itself in the fact that there aren't any good OLED displays on the market yet, while LCD technology continues to get better and better. Most people don't realize that 90% of the power used by an LCD goes into the relatively inefficient CCD backlight. An LCD with an OLED backlight as described should be able to offer energy efficiency better than that promised by conventional OLED displays, as well as image quality consistent with modern LCD technology.

I think it may make the displays thicker though.
Can't wait until this is mated with transparent wire technology to provide screens on your walls... Maybe that's a few decades away though lol.
Imagine 1/8" thin panels that could be stuck up like so many pieces of paper and which emitted a soft, shadowless light.

There's a lot of talk but no play in this field. Wake me up in 2012 when something may actually happen...like more talk.
Umm, the lab has been going for 13 years. Now there's a result. That's not talk, that's a result.

A result is something I can hold in my hands. Does the iPod have OLED? No. The MacBook Pro? No. The 30-inch Apple Cinema Display? No. The Canon S3 IS? No. How about a $5,000 big HDTV? No.

Sounds like there might be real promise for general interior illumination, not just display backlights.

'1/8" thin' - Now we know who you really are addabox, SJ himself - yourself!

The problem with sunlight readability is that ambient, outdoor light tends to have different tones based on the environment. So you can't get true color. The other issue is that aside from some very new displays from Samsung (which are small), transflective displays require a rear one-way mirror that greatly increases that thickness of the display module, as well as limits indoor brightness.
So, for the time being and the foreseeable future, laptops will not be very useable in direct sunlight. There's not much anyone can do about this.

There are several on the market today. Some cell phones have OLED displays.
