    AMOLED release order: Phones, Tablets, TVs, Flexible Displays,

    Then, at long, long last, Lighting.
    Let us not forget.
    Samsung, almost the sole AMOLED maker, is all LTPS all the time!
    No one does LPTS like TCZ!!
    NO ONE!!!
    Where have all those “beta” tools been for nearly 4 years?

    IMID Notes from Daegu, Korea 30-Aug-12 08:41 am I took these notes from the following lecture on Wednesday:

    [Invited] Progress in Solution Processed Phosphorescent Organic
    Light-Emitting Devices
    Sean Xia, Kwang-Ohk Cheon, Mike Inbasekaran, Mark Rothman,
    Patrick Hett, and Julie J. Brown (Universal Display Corp., USA)

    Sean was the person presenting.

    The timeline for OLEDs is (first to last): Phones, Tablets, TVs, Flexible Displays, Lighting.

    Power efficiency is important for OLED screens. You need good materials to make power efficient screens.

    The lifetime of the display is important. He talks more about this later.

    OLEDs make for various form factors: Flexible, Unbreakable, and Thin Film.

    Methods of manufacturing were also discussed.

    Compared to flourescent OLEDs, phosphorescents do the following:
    Red drops the power usage down 25%
    Red combined with green drops the power usage down 45%
    Theoretically, red with green with blue would drop power usage more than 60%

    OLEDs are superior displays: They're thin, have 180 degree viewing angle, true black, 1/1,000,000 contrast ratio, and may cost less than LCDs when produced to scale over the long run.

    He talked about how long the materials last in terms of...I forget the the conferences Sid always says something like "they last this long to 95% (some word for still doing a good job and showing good coloring and being bright).

    Anyways, the following list is the colors, followed by the hours for 95% and the hours for 50% (I didn't get everything because I wrote too slowly)

    Deep red: 14,000
    Red: 23,000...600,000
    Red: 50,000...900,000....(I don't really know why there were 3 reds listed)
    Yellow: 85,000...1,450,000
    Green: 18,000...400,000
    Light Blue: 7,000...20,000

    Advantages of solution processing over VTE:
    1. It's done at a lower cost over a large area
    2. It raises material utilization rate
    3. You can put more stuff in 1 layer this way
    4. It allows for better reproducibility

    Why are small molecules better than polymer?
    1. They raise color efficiency
    2. It gives high material purity
    3. It increases reproducibility
    4. It's easier to drive off solvent
    5. viscosity is controlled by solvent systems
