1. A method for addressing a bistable electro-optic display having at least one pixel, the method comprising:

  • 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.
