I held a colour 60Hz electrophoretic display a decade ago (first startup).
Electrophoretic displays can go at very fast refresh rates if you just zap
them hard enough (i.e. high voltage on the TFT). Without higher voltage they
can still run fast but at the expense of losing contrast. You basically have
little black and white "balls" (electrophoretic particles) travel up and down
in the field (in those little e-ink cells). At conventional voltage the balls
won't travel the full distance in a single fast image frame, so you won't get
full black or full white. The problem is that people want colour, speed and
low power consumption. Those are opposing requirements and E-ink made their
bet on power (at the expense of colour and speed).
