Summary: | The present invention relates to a method of addressing a bistable matrix screen, in which the following two steps are reiterated: A. a disturbance signal is applied to each pixel of a marking area for a time t1, said disturbance signal being higher than a threshold signal such that each pixel of the area leaves its initial stable state, said disturbance signal being lower than a switching signal such that each pixel of the area having one of the stable states as its initial state does not switch into the other stable state, each pixel of the area then being in an intermediate disturbed state that is intermediate between the two stable states, and then B. no signal is applied to each pixel of the area for a time t2 to allow each pixel of the area to return to its initial stable state. |
