Chi Mei Announces 20" Active Matrix OLED Display

deglr6328 writes "The final barriers to OLED commercialization have been falling fast lately with Kodak's first product shipping soon, Samsung demoing a 256 color OLED wristwatch phone and now Chi Mei Optoelectronics announcing a 20 inch full color active matrix OLED display. The new display was made possible by a breakthrough using amorphous silicon for the TFT. The new technique is said to allow conventional TFT LCD manufacturers to convert their facilities over to OLED with relative ease."

    Will this mean cheaper displays for the consumer or are they going to be sky high like LCDs were for a few years?

    Unless they are much greater than LCDs in some respect, I don't know why the regular Joe Bloggs would want to upgrade from a CRT.

      The specs are indeed impressive. A 20 inch display running at 25 watts is wonderful. Not only are these going to be good for desktops but think about laptop uses. Longer battery life, better viewing angle for that presentation at the office, and most importantly a bright and vivid display that wont make your eyes hurt like some LCD's. Also in a few years these things will of course be cheaper but better to. These are simply prototypes and first generation models. Soon they will draw LESS energy and be brighter, lighter, cheaper, and probably cool (maybe not possible). So im not buying one yet (living off a student's income... ie slim to nil) but i can see a time where these things are too good to NOT buy. Whoever is selling these is going to make a fortune because as the old saying goes i predict they will almost sell themselves.

  2. Why this is important. by Anonymous+Freak · · Score: 5, Informative

    Yes, the early ones will be expensive. But, the whole point of this technology is that it is cheaper than LCD. Once the initial R&D has been paid for, they will be cheap. Plus, take a look at those specs. 300 Cd/m^2 at 25W. The Apple 20" Cinema Display only has 230 Cd/m^2, and it uses over twice as much power, 60W! These are a big deal because they use even less energy than an LCD, and they'll be easier to manufacture. (LCD's are actually easier to manufacture than CRTs, but economies of scale kick in, that's why CRTs are so much cheaper. Plus LCDs are prone to pixel failure, which OLED displays supposedly aren't.)

    For large screens with OLED, I'll assume it pretty hard to be something for Full-screen video or showing purpose, which is located far, far (i.e. >30cm) away from the viewer, hence the resolution need not be that big.

    FYI, a typical TV screen has much less resolution (i.e. around 640x480 - don't bitch me about the 525 lines bit - I know it and Please note that there is something called Vertical blanking interval, google it if you dare.) and I'm very, very happy with it.

    I think most of the guys/gals/geeks/etc. will be happy with that big a screen with that quite-a-bit of resolution for gaming/movie/pr0n[sic] purposes.

    1) TV in america (or more specificaly NTSC) is 640x480. PAL is 832x624 (625 actually, but 1 line is used for Teletext).
    2) Some of us, (including me) would actually like to do some work on our computers, now for me that means at least a resolution of 1600x1200 (if not 1920x1440).

  5. Re:I wonder if they've solved... by gollangana · · Score: 4, Informative

    LCDs have defects due to the failure of the Thin Film Transistors that control the state of individual pixels. Given that OLED displays will be using identical TFTs there should be a similar (or worse, due to failure of the OLEds themselves) rate of defects. However - when a TFT fails in an LCD it gives a light point, wheras when one fails in an OLED display it will give a dark point, which is much less annoying.

    CDT work with novel polymer displays which, particularly in the blue, have stability problems.

    This display is made from small organic molecules - a more mature field and is unlikely to suffer degradation effects any worse than say, a plasma display.
