It actually uses a polymer that emits light when voltage is applied to it. By coloring the polymer red, green, and blue, and spraying it on a base with an opposing charge, you have a color display. It's a solid-state deal.
Close, but not really. These things aren't like christmas tree bulbs that are really white and just painted. They develop different polymers that actually emit blue light. Since blue is so high on the spectrum, it's sorta hard to find something that will emit low enough blue that you can see it. That's why it was such a big deal when they came out with blue LEDs a few years ago. if you look at a blue LED when it's off, it's clear, not blue. same with green. That's also why the blue has such a short life-span. Red is low freq. so you can power them for years. green takes more power. blue takes even more.
