MIT explains OLEDs using a pickle
The headline makes it sound crazy, but after watching the video from MIT, it makes complete sense. Professor, Vladimir Bulovic does a delicious demonstration of how OLEDs are simply organic substrates sandwiched between electrodes. Eventually, he ditches the pickle and uses Sony's OLED XEL-1 to demonstrate exactly why OLED displays can be so thin and still look so good. I won't attempt to explain it any further since you really should just watch the video. Even if you're not interested in hearing about how much easier OLEDs should be to produce than LCDs, at least you'll get to see a glowing pickle. Everybody wins.
