@kenjennings I think you're spot on about the fixed pattern segments on the Esquire cover. Sheer cost alone precludes the screen being little more than a glorified electrically controlled two state hologram. PonMan has confirmed that the EE does a deliberate clear between each page change. What I'm wondering now is can they drive the display in such a way that the clearing process produces an intermediate white page rather than an intermediate black page. This I imagine may still lead to some sort of ghosting for which the black flash is the only solution. So I guess it looks like we're stuck with the flashing.
