OLED???

  1. 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!

  2. 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.
     
  5. 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...

    I think you meant LCDs. LEDs are light sources.

    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.

  8. In all the MS webcasts i notice the redmond folks say "dub dub dub",
    and for product like 'WWF' they say "dub dub ef"
     
  9. 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.
     
  12. Oh dear, you were doing so well up to this point..

    And in Yiddish, (Oy) Vey Vey Vey!
     
  15. 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.
     
  18. Roy L. Fuchs

    Roy L. Fuchs Guest

    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.
