As far as flashing white/black/invert, it depends on the device. I think most of them do an invert though. It helps keep the separation of the particles clean so that you don't get a handful of them stuck on the wrong side (which is what causes ghosting).

Ah. Thanks, Shaggy. Been TOO long since I first read about the technology when it was first coming out of the lab, and I'd forgotten the details of the mechanism apparently. The flash makes more sense now.
