1. , a kind of driving method that is used for display device, this display device comprise a plurality of pixels (PIX1, PIX2, PIX3, PIX4, PIX5, PIX6), each pixel comprises:

  • First drive electrode (10), its first area (110) with pixel is relevant;

    Observe electrode (14), its second area (112) with pixel is relevant;

    Second drive electrode (12), its;

    Be between first drive electrode and the observation electrode;

    Border (114) between first and second zones of pixel is located;

    AndCharged particle (116) movably;

    AndWherein, be applied to first and second drive electrodes and observing under the influence of control signal of electrode, changing the optical appearance of each pixel by the charged particle number near controlled observation electrode, wherein said method comprises for each pixel;

    In pre-address phase (PRA), control signal is applied to pixel, move described particle with second drive electrode of locating towards the border (114) between first and second zones;

    ThenAt address phase (ADD), control signal is applied to pixel, with expectation optical appearance, described particle is moved to the first area or moves to second area according to pixel.
