OLED, eh?

A few days ago, while reading about the soon-to-be-announced iPad, I read that it may have an OLED screen. Huh? OLED? SO, this old guy had to google "OLED" and now, having explained it to Heidi, I have to write up a tutorial on Organic Light Emitting Diodes. What surprised Heidi (and me) was Organic? I'm sure I've seen something like that on Star Trek. If'n (like me) y'all don't know about OLEDs, the tutorial will be over there ... soon.
