        AFAIK, they're called "organic" because they're based on organic molecules, i.e. organic chemistry, which is primarily concerned with carbon-based long chain molecules.

        One thing that I wondered about is the article says OLEDs require more power than LCDs at the present time. I thought that one of the main benefits of OLED was that they'd use a lot less power and so would extend laptop battery life, amongst other things.

        Can anyone explain that?

          This is because an LCD display is inherently inefficient. We can realistically assume that the LCD matrix itself has near-zero power requirements, and the backlight is somewhat more efficient as the OLED in converting electricity to light. However, the color filters in the LCD cut out at least 2/3 of the light output, and the polarizers eats up 1/2 of the rest, and the remaining 16% of the light is the white level. In other words, if your LCD screen is all white the efficiency is no more than 16% of the backlight output, and if your screen is black, the efficiency is 0.

          There are other issues with LCD:

          1. Contrast. The black areas of the LCD always leak some light, creating the contrast issue. With OLED, black means "light off", so the issue isn't there, unless you were using shitty drive electronics that prevented you from turning the output off completely, which would be stupid.

          2. Viewing angle. All LCDs have this issue, even though it's gotten much, much better with the newer ones. The reason for this problem is that. angle of polarization doesn't rotate properly when the light goes through the liquid cristal at an angle.

          3. LCDs are mechanically awkward. They are sure better than a vacuum-filled glass jar, but there still have to be two sheets of high-precision glass with a precisely controlled gap in between, and a backlight tube. The whole thing is rather fragile. An OLED doesn't really have to have any glass in it at all, even though the first ones do.

            4. LCDs are slow. This got better recently, but the problem is inherent in the way an LCD pixel turns off.

            To turn a pixel on, you apply an electric potential that breaks up the crystal lattice and turns the liquid crystal molecules vertically WRT to glass. This can be made faster by using higher electric potential, perhaps.

            To turn the pixel off, the long molecules of the liquid cristal material have to turn and recrystallize parallel to the glass, creating the twisted lattice that turns the polarization angle of the passing light. This happens by itself, w/o any energy input to the material, so you can't just "crank up the power" and hope for a faster display - you have to invent a material whose energy is significantly lower when it's crystallized parallel to the grooves in the glass than when it's not.

            OLED displays, OTOH, turns on and off within microseconds, just like any LED.

    • In most laptops the LCD screen failure is caused by the backlight breaking - if you shine a really bright light at the screen you'll still be able to make out the LCD display. Obviously most users don't have the know how to replace a backlight, and so just buy a new laptop.

      The point is that OLED's are not made of the same stuff that your normal "big" LEDs are made of. What they have in common is that they are diodes and emit light. Consider that the Panasonic screen has over 18 million of them packed in an area the size of my monitor. That's pretty impressive.

      What's not impressive is that they tend to grow fainter with time. The article says 10,000 hours before they lose half their brightness... that's not very long, and I'm sure you'd notice the effect well before the 10,000-hour point. Elsewhere I read that this dimming is not even across the color range, and that the images get progressively more red. LCD displays are supposed to lose half their brightness in 30,000 hours, which is not that much better imo. That makes me wonder about CRTs. My Sony 500PS is pushing 7 years and still looks beautiful. The only difference I notice is that it takes a bit longer to warm up than when it was new. Ah, trusty old CRT! As long as I keep my big desk, I probably won't even be thinking about a new monitor before 2008. I know that "degradation with time" probably makes the salespeople happy, but I know that when I'm looking to replace my monitor, I'll be looking for something that doesn't have an obsolescense plan.

Spatial resolution, temporal resolution, effective resolution (like how if your dot pitch isn't small enough, you may not actually be seeing 1600x1200 pixels when you tell your CRT to do it), differing chrominance and luminance resolutions, or the more traditional optical usage that means something like "how small an object we can discern as a separate object" etc... all confuse the issue.
        • Yes maybe in 30 years of using computers you would have heard resolution mean anything other than the number of pixels. But in the TV world there are concepts called temporal resolution and spatial resolution. Spatial resolution is indeed just the number of pixels, whereas temporal resolution is the # of pixels * framerate. I'm sure that they're talking of temporal resolution in this article, and it makes sense to. This is what we really perceive.

      While odds are it's just horrible writing there is one thing I can think of; it may be similar to the "wobulation" used on DLP displays.

      Pop Sci link on wobulation [popsci.com]

      Basically since DLP displays can't be made to have a physical resolution high enough for HDTV but they can change pixels awfully fast they have each DLP element alternate display of two different colors very fast which tricks the eye into thinking it sees 4 pixels worth of information. The article does a much better job explaining it.

      • It is also the reason why a lot of people see rainbows, get headaches and notice motion artifacts watching DLP based sets.

        Some people call this "temporal dithering" (as opposed to the regular kind of dithering, which I guess is spatial dithering) and the reason for it is that DLP pixels are either 100% on or 100% off at any given time, with no middle ground. If you want to display 50% gray on a DLP, your pixel has to be white half the time and black half the time.

        While DLP is fast, it's not quite fast enough to make enough colors using the temporal dithering a

          If you want to display 50% gray on a DLP, your pixel has to be white half the time and black half the time.

          Actually, it is worse than this for home and low-cost DLPs. With an RGB color wheel, the red would be on 1/6th of the time, green for 1/6th and blue for 1/6th. The 1/6th is best-case as there are usually delays when the color is changing. I'm not sure of exact color order though.

          The best way I could sum it up was that the LCD to DLP relationship was something like film to video. Good video images have a sharpness that film doesn't have, but good film images have a smoothness that video doesn't have. I choose smooth.

      • I think wobulation relies on moving some optical element within the projection system. I doubt it would be good for a 21" flat panel.
        • You can do temporal dithering on an LCD to get your 'intermediate' value pixels somewhere in the middle of the two. I've seen it done on high end IBM LCD displays.

          Also there is a limit to how small you can make an LCD and still have a sufficiently response time (also how large, too). OLEDs will not have this limitation.
      • This wobbulation looks more like a smoothing technique than anything else. You don't get any more resolution. At least not the way that link is describing. If you can shift the optical path in between you can increase the resolution. if you dont' all you get is a smoothing algorithm, which could be done on the input side for that matter.

        I haven't seen a display using one of TI's 1280x720 chips claiming they do 1920x1080 resolution. Sounds like complete BS to me.

        Also TI does have a real 1920x1080 DLP chip.
        • Currently only HD3 engined DLP sets use wobbulation. HD2 and HD2+ do not wobbulate, they are native.

          The HD3 chip is actually 640x720 and shifts the chips midstream to wobbulte to 1280x720.

          Viewiers are split. The image on the wobbulate sets is smoother and screen door is eliminated, but the overall image is softer.

      I don't know Nash's theory, but what appears to be happening is that the different huge Asian conglomerates are each persuing different technologies. This is a relatively new thing in the TV market, and exposes a new layer of competition. Up until a few years ago, companies were mostly competing at the margins of features and price, and we had big, beautiful, feature-rich CRTs at remarkably low prices (and low margins for the manufacturers.)

      Now, though, we see Sharp (for example) betting the ranch of LCDs, Toshiba and Canon going for broke on SEDs, Samsung and LG with these OLEDs, and other flogging plasma panels for all they're worth. Rather than competing on marginal features, they are all desperately competing in basic science and process engineering. It's amazing to watch, and I can imagine that the pressure on the development teams is intense -- because it's likely that all but one of these technologies will be abandoned when the winner is apparent.

      I'm betting on SEDs, because they provide high quality, reasonable manufacturability, long life, and build on the best of current CRT technologies. OLEDs will rule if, in the end, it is possible to get the science to work -- I'm just not convinced yet that it is.

    What's the power consumption of a unit like this? How does it compare to an LCD screen?

    Chosun.com has a picture

    I strongly doubt that this picture is actual footage from the display picture-quality. Seems to me that they've inserted a nice image with some photo-editing software. It is just to show the outer case.
  • I've read that what made OLED displays troublesome for so long was creating a pure-blue LED that had long life.

    I wonder if this first generation of consumer OLED displays will last as long as a CRT.

    I hope they last longer than a Plasma display, since color fading is one of that technologies drawbacks.

  • ...on my phone (E700), the front screen is a small OLED. The thing you notice immediately is that it can be viewed perfectly from any angle (compared, for instance, to the TFT on the inside screen which has the normal LCD viewing range). Since it is light emitting (rather than requiring a backlight) the black is also pretty much as black as a CRT.

    ...using active matrix-based (AM) technology on Tuesday

    I wonder what it's using the rest of the week... Maybe it goes into passive mode (or does this only happen on Sundays?
  • ...did what I just did - race over to the jpeg of a photo of a better display than my iBook to see just how much more wonderful it was.

    Looks great! ;-)
  • I think while Samsung is commended for getting OLED's to 21" size, they're going to have a seroius competitor for truly flat displays with the Canon/Toshiba SED (Surface-conduction Electron-emitter Display) that will be available on the market in the fall of 2005.

    Sure, SED's do use more power than LCD's, but SED's make up for this with CRT-level brightness without the finicky geometry calibrations needed for high-resolution CRT's. It will be well after SED displays become commonplace that we'll see a proli
  • OLED display responses are 1,000 times faster than liquid crystal displays (LCDs), thus enabling greater resolution.

    How does this make sense? How does faster switching time == greater resolution? This really leads me to wonder about the veracity of these articles.

  • Of a *picture* of an OLED display, if you're only going to be viewing the picture on a *LCD or CRT*? I mean, how can can you ever appreciate it???
    • re: 861 -- that's a nice use of flash; but why can't the 861 people find somebody willing to go to court about their taxable income -- I am sure funding could be found (I am not an American so the whole business seems bizarre in the extreme to me.)

    Perhaps it's related to superman flying backwards around the world fast enough to reverse time so the pixels shrink to their infant state...

    Caption under the picture of the OLED display on Chosun.com reads:
    "Samsung Electronics unveiled the world's largest 21-inch organic light emitting diode (OLED) display"

    How can it be the world's largest 21-inch OLED display, aren't all 21-inch displays 21 inches?

    Looks interesting though.

  • According to this IEEE pdf document ... [ieee.org]

    Seiko Epson, using inkjet printing, unveiled a 35-inch (88-cm) prototype full-color OLED display in May-- the industry's largest OLED screen. Seiko Epson says it will be able to produce large OLED TV panels using this technology after improving its OLED materials and extending their lifetime.
