Sorry for the newbie question, but I can't find the info online. Does an LCD use more power showing a white screen than a black one? Or does it just leave the bulb on all the time, and which pixels are open or closed doesn't affect power use?
Also, I thought that an incandescent bulb could burn at varying power and brightness, but a flourescent bulb had to just be on or off. Is that true? If so, why does an LCD use more power at higher brightness?
Thanks!
