Hi. How do you pronounce it? Will just a few companies manufacture the display material itself, or will the electric print idea make it so everyone can do it, or am I confusing different ideas? This is new to me, and there's so much potential it's hard to know how to think about the whole thing...
I imagine the number of companies producing the substrates will eventually be fairly large, I don't think it's that much more difficult than making good LCD panels. I'm pretty impressed with what I've seen so far. No panacea, but it's a nice option.
Best regards, Spehro Pefhany

I heard it with all four letters pronounced, just like the LED has all three letters pronounced. Afterall, they roll off the tongue fairly well, unlike say, WWW, which as three times the syllables of "world wide web".

You are't very bright. The technology is entirely different than LCD manufacture.
OLED (pronounced Oh-Lead) Is Organic LED.
EVERY PIXEL is an LED, fully illuminated by current level, and individually wired... YES WIRED.
IBM manufactures what is STILL the highest resolution display ther is. A 19 MILLION pixel OLED monitor.
It has several miles of wiring in it.
It also only refreshes at 24Hz in its highest resolution.
I'll give you three guesses as to who their target market is, and the first two do not count.
Oh, and yes... it is out of your budget range.
OLED will be the hot shit when it become manufacturable in a cost effective way. Not right now though.
The reason is that LEDs are not light sources. They are illuminated from behind and express serious limitations in color producing capacity as a result.
OLEDs are individually fired pixels and produce their own light at the pixel level, just like a CRT does when an E-beam strikes a phosphor. An LCD cannot produce an entire range of colors due to their lack of this capacity.
Not quite true. It is simply a matter of matching the filter and the light source behind the LCD so that only the desired primary comes out.
Light from common LEDs can be fairly close to monochromatic, as you point out, but similar effect can be had from LCD by using filters with reasonable isolation between the primaries and using a backlight composed of line spectra of the primaries instead of broad spectrum white light.
False. I do photographic color retouching on a LCD pro monitor and it is color calibrated and calibratable. Color is BETTER than on an equivalent CRT. My Samsung 32 LCD HDTV is the best picture and color I've seen and I have seen the Pioneer Elite Plasma--neighbor has one. CRT TV's/monitors aren't worth two cents IMO. CRT monitors especially give me eyestrain when working and LCD doesn't. Maybe this new OLED technology WILL be better but for some reason for some people that which is unavailable is always THE BEST.
That makes sense. LCDs have separate light sources, primary color filters and shutters. Each component can be optimized. Particularly the primary color filters, being nothing more than fixed filters, don't have to be a design compromise between light emitting, control and hue that LEDs, phosphors, etc. do.

If your brainy (claim to be) ass knew what the color triangle looked like, and where displays fall into place on them, you would KNOW that an LCD display CANNOT reproduce the same spectrum as a CRT, OR an OLED. Hell, they even have problems with grayscale production.
You need to bone up on monitors and displays, Chucko. I don't what you have been calibrating with what instruments, it doesn't mean that you know jack squat about display devices.
