Samsung announces 'largest ever' organic LED display

Samsung announces 'largest ever' organic LED display

Summary: Samsung's new organic monitor may compete head-on with existing LCD technology

TOPICS: Emerging Tech
Samsung SDI, the Korean giant's display division, has announced prototypes of a 17-inch active matrix organic light emitting diode (OLED) display. Due for launch next year, the display has a resolution of 1600x1200 pixels and a brightness of 400 lumens, and is the largest OLED matrix display to date according to the company.

It will consume no more power than a 15-inch display and be a third of the thickness of existing LCD models, the company said. The prototype will be shown at the 2004 Society for Information Display (SID) conference, taking place from 25th May in Seattle.

The displays are made using a transfer technology developed by Samsung and 3M, where the pattern of plastic pixels on the screen is printed by scanning a laser across a set of organic films. This can produce a larger screen than is possible by the alternative method of spraying the plastic through a patterned shadow mask, says the company, while allowing a similar precision.

Organic LEDs are luminescent plastic semiconductors with the theoretical potential to replace LCDs, CRTs and other display technologies through greater efficiency, easier production, more physical flexibility and lower cost. To date, however, problems with device lifetime, chemistry and production have limited their use to mobile devices and backlights. Samsung's basic OLED technology was licenced from Kodak and developed in conjunction with NEC, which sold its stake in the joint venture to Samsung at the beginning of 2004.

  • Not quite the largest:

    Seiko Epson unveils first 40" colour OLED display
  • Epson's OLED isn't due until 2007, Samsung's OLED is due next year.

    While it's true Epson has announced the larger size, it's obvious that they're just announcing a far-off product in an attempt to steal attention from Samsung's legitimate breakthrough.
  • the title of this article is incorrect. Seiko has a 40" unit working.

    See this link.
  • The Epson display is physically larger, but it's really four displays bolted together -- not very well, according to some reports I've ready -- and even as a whole it's got a much lower resolution than the Samsung. It's also not due to launch until 2007, and I think the announcement came after Samsung's.

    And if that's not enough, we just reported that Samsung *claimed* to have the 'largest ever' OLED display!

  • To the author,
    Are you assuming it is Kodak's fluorescent OLED they are licensing or did you get that information from the company? This is AMOLED and Samsung only has a license for PMOLED from Kodak. Additionally Samsung SDI has been in a JDA with Universal Display Corp. to develop AMOLED for several years. I would have thought this display incorporated UDC's PHOLEDs perhaps in addition to a blue fluorescent from another source, and not necessarilty Kodak. This is a question really and not necessarily an argument. Thanks!
  • Picture of the Epson unit on their press release here:
  • Thanks for the link to Epson, but if you read the specs, it is larger (40"), but has lower resolution (1280x768) compared to 17" and 1600x1280. Both are remarkable, too bad prices are not compared
  • The main point of interest to me is the Epson use of inkjet technology to "print" the organic layer on the TFT screens. I think that the new technology promises not only a slimer, lighter screen but it may well be much less expensive than LED to manufacture.
  • Until:

    1) They have at least 1920 x 1080 resolution in at least 19" screens; and,

    2) Can be reasonably expected to last at least 5 years with no more detioration than a CRT (no ROT or pixel failure); and,

    3) The colors are good enough (and STAY good enough) for video editing and color matching without having to buy some "special" unit; and,

    4) They cost no more than a typical LCD; and,

    5) They have AT LEAST a 1000:1 contrast ratio,

    I will just wait.
  • OLED is not just used as display. Also, it can be used as light source, wall decoration etc. The same (or similar) material can be used for thin film transitor, organic memory etc. It is going to be imprtant technology in 5 years.

    A software company called OD Software Incorporated (ODSI) ( toolkit to help the industry to develop this new technology in aspect of project management, simulation, device modeling.

    A group also discusses, and provides free information about this technology. This group is ranked as top three in nanotechnology category by Yahoo.
  • So this means that Universal Display is in the driver's seat and NOT Kodak with respect to Samsung.

    Check the Universal Display website for partners. Look at the 7/28/04 news and scroll to the bottom where you see partners listed. Samsung can't have Kodak and UDC both as partners. Get your story right.
  • The cost at which the Samsung Corporation is going to sell this device to it's customers in Third World Countries and whether it is going to be affordable to them is unclear.
  • We would like to buy a large sceen of 500x300 mm
  • Looks like Samsung are well on the way
  • Is this product available yet?
  • OLED Technology is the Display for the future!
    small, thin, low energy and so on!
