What you're describing is true of power budgeting for E-Ink displays. LCD's, however, always require some amount of power even just to preserve their image. It may well be that they use less power to display a static image than to display a changing one, though; but I don't know.I'm pretty sure that, once a pixel on an LCD is set to a certain color, no more energy is needed to maintain that pixel until its color needs to be changed. That is, a black pixel requires just as much energy as a white pixel, but that the energy is consumed in changing each pixel to a new color and is only consumed during that update.
Yep.The real drain is the backlight, which is always shining and always blasting its way through every single pixel on the screen. That's why black isn't really "black" so much as it's "really really really dark grey".
I wonder how much MORE energy is wasted performing the power saved calculations. Not to mention the energy required to run the additional servers. I understand the good intentions of using the site, but don't blindly accept something as being true because someone says it is. You might end up hurting the cause you're trying to help.
Hmm..Where to start. Well, first off, these calculations can probably be done on a solar calculator...so lets not be so dramatic here. Second, i dont use the site at all, its just something i stumbled across. Third, its just a website! No need for all your philosophical babble about blindly accepting things and hurting the world. Thats all.
