[Cialug] OT: LCD Pixel power?

[Nathan C. Smith]

I have a question regarding LCD displays.  Does it take more power to show
pixels of a particular color - are dark pixels harder on power than light
ones?  Or does the nature of the LCD require even power through screen at
once?  Is the backlight itself a bigger power hog than the screen?  (If it
is bring on the LED backlights!)

The background of this question is if there is if there are any screen
contents or color schemes that can reduce battery usage - I'm betting there
aren't.
