A method for addressing a bistable electro-optic display having at least
one pixel comprises applying an addressing pulse to drive the pixel to a
first optical state; leaving the pixel undriven for a period of time,
thereby permitting the pixel to assume a second optical state different
from the first optical state; and applying to the pixel a refresh pulse
which substantially restores the pixel to the first optical state, the
refresh pulse being short relative to the addressing pulse.
