If the epaper display involves white and black pigments travelling physically through an oil droplet, then I doubt that the lifetime of a pixel is infinite. Can't find lifetime specs on eink.com, though, only a claim that 90% of the displays will live 10y at typical usage, whatever that means (one page-flip per minute?).
