OLED???

[dh@.]

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...

Thanks for any info!

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.

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".

oh-led

surely.

oh-led

surely.

That seems right to me, but I wonder how they would
verbally differentiate between FOLED and PHOLED.
It's hard to find people who are very familiar with this
stuff...which may be a good thing.

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.

If they can get the service life up...

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.

Funny, the ones I have here look a lot an awful lot like LCD displays.
Glass substrate. Multiplexed, of course, which works better with
diodes than LCDs.

They are *already* competitive with VFD displays. They've been used in
one manufacturer's consumer products for several years now.

Whatcha smoking, dude? LED = Light EMITTING diode.

Yes, the gamut varies with different display (and printing)
technology, if that's what you are trying to say. I should have some
full color ones in hand in a couple of weeks.

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.

Which LCD monitor do you use?

Better color than a CRT? Color me skeptical.

Oh dear, you were doing so well up to this point..

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.

Yes. Mild dyslexia. Bad place for it to happen, though. :-]

Did you get a chance to look at the BACK of the OLED panel?

Get back to me at that time.

Oh, and it is a glass frontispiece.

Yeah right. An MP3 player/picture viewer with an array size
amounting to a few thousand pixels.

Where are the large OLED FPDs at? Well...?

I guess the reader (YOU) would have to have enough brains to know
that I was actually talking about LCDs. Just look at the description
given in the body of the text. LEDs are not backlit.

You know damned well what I was talking about, OR you are one stupid
fucher.

Whoopie doo.

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.
