What I understand is that the screen have bits which are white on one side and black on the other and an electric field causes them to change back and forth. Do these bits cover the entire area of the screen, like a fence or do they move around where needed? Does the field needed to keep most of the screen black versus the normal white give any extra wear and tear?

Completely random late night question but now I am feeling like a kid asking why the sky is blue ;p
The screen is laid out as a grid of pixels in fixed locations. Each pixel has several spheres that are half black and half white, whose orientation is controlled by an electric field. When the page is changed, some of the pixels with white up turn black and some with black up turn white. When the screen colors are inverted, the same pixels have to change, just opposite color, so no difference in wear and tear.
