It's funny how something can seem a certain way one moment, and then you learn something new and that thing will never seem the same. This just happened to me wrt to LCD screens. I thought that I knew how they worked more or less, but when someone asked what makes them bright, I realized that I didn't know how they work at all. Wow, fluorescent lights! Who knew? I guess I never really thought about it, but now when I look at my screen it is painfully obvious; so much so that it even bothers me a little.
