incorporated herein by reference in its entirety for ease of illustration the four types of particles may be referred to as a first type of particles a second type of particles a third type of particles and a fourth type of particles as an example shown in fig5 the first type of particles is black particles k the second type of particles is yellow particles y the third type of particles is red particles r and the fourth type of particles is white particles w in this example the black and yellow particles carry opposite charge polarities for example if the black particles are positively charged the yellow particles are negatively charged the red and white particles are also oppositely charged however the charges carried by the black and yellow particles are stronger than the charges carried by the red and white particles for example the black particles k carry a high positive charge the yellow particles y carry a high negative charge the red r particles carry a low positive charge and the white particles w carry a low negative charge the driving sequence of this type of color display device is shown in fig6 in fig6 a when a high negative.
