Abstract
Provided is a method to drive an image display medium. The method may include applying a variable voltage to a common electrode provided in a first substrate, applying a second voltage to a pixel electrode provided in a second substrate through active matrix driving, wherein the image display medium includes a plurality of kinds of particles sealed between the first and second substrates, the plurality kinds of particles having different threshold characteristics of voltages required to move the particles between the first and second substrates; and controlling through a controller to apply a third voltage between the first and second substrates through a plurality of steps in which the third voltage minimizes particle movements between the first and second substrates during a deviation time such that particles do not move when a potential difference between the first and second substrates is equal to or less than the threshold characteristics of the particles, wherein the deviation time is generated due to deviation of a scanning timing and the potential difference between the first and second substrates.
