Sony Begins OLED Mass Production

Posted by timothy on from the not-a-moment-too-soon dept.

Dodger73 writes "According to their press release at sony.net, Sony beings mass production of full color OLED displays at 3.8" size for their Clie PEG-VZ90 'Personal Entertainment Handheld.' The press release claims, that their 'Super Top Emission' technology reaches 150cd/m^2; at the familiar 1000:1 contrast ratio. Not quite the 19" display I'd like for my computer at home, but definitely a step in the right direction."

    OLED = Organic Light-Emitting Diode

    Just don't use any anti-bacterial soap before handling it! ::swish::

    One step closer to everything we've been promised the past few years. You want a roll-up screen to go with your fold-up keyboard? This is the technology line that will make it happen. Window curtains that can change color, table-tops that are skinnable...think of it.

    Now if we can only get the price down enough to make such trivial applications a reality.

  4. Power consumption.... by imsabbel · · Score: 5, Informative

    should be quite a bit lower than lcds. The diods are far less efficient than the lcd backlights, BUT:
    -You dont need polarizers and color filters (those absorb >2/3 of the light in a lcd)
    -Dark pixels are just not powered/lower powered (if the typical brightness level is low, this is another factor of 2-4).
    So the organic leds only need 10% of the effience of normal ones to break even, which should be very archiveable.

  5. lifetime of display? by mshultz · · Score: 5, Informative

    Has any progress been made regarding the life of these displays? Last I heard, the longest these things would last was about a year or two before going too dim to be useful.

    Unless Sony is figuring that the early adopters will be people who tend to buy new PDA's quite frequently anyway, and will therefore be willing to get rid of this one once the next generation comes out the following year...

  6. Re:failure rate is still high by Blitzenn · · Score: 5, Informative

    NO real progress has been made in that area. The color failure rate is still pretty high. the typical failure is a pixel getting 'stuck' in the on or off position. Being that the display is more expensive to make than other available technologies, they probably won't be replaceable and will make the units, escentially, throw aways or disposables.
