I'd like to see the presentation if you could PM it to me. I'm totally up for that part of this to be true either way: I have no skin in the game, and would love to learn. BTW, I'm frustrated with LG. It seems that every time someone over there tries to explain something they contradict it later. It's almost as if their marketing team just cant shut up long enough for the engineers to talk properly.
I want to know more about the stacking interactions as well.
The dichromatic blue + yellow phosphor in the documents is a confusing one. Because they both are emission entities, they get labled blue + yellow, and sometimes blue + red/green carelessly. I went with the information and explanation from ynotgoal a long time ago because it followed the kodak patent that presumably everything was based upon.
That, and I believe that dichromatic white from a blue LED and yellow phosphor was the first way a white LED was created a long time ago.
In the LG case the yellow (or red/green) emitter is NOT a photo excited phosphor like you see in LEDs/Plasma/Fluourescent light bulbs. They are seperate red and green phosphorescent EL materials (ie - singlet+triplet).
I don't doubt you on this detail, but I would love confirmation from this in engineering paper form. ynotgoal's argument was exceedingly convincing months ago. BTW, curious: a phosphorescent driven how? A thin film luminescent just like the OLED underneath current/voltage driven?
PS. Thanks for the image over PM Slacker. I look forward to seeing more.
What we may be seeing here is the difference between what the engineers within LG would tell us vs. how the reps and marketing were told to explain it. This of course could mean it goes either way.
