ABSTRACT:
The present invention is directed to an electro-magnetophoresis display having either the traditional up/down or dual switching mode. The display cells are filled with an electro-magnetophoretic dispersion comprising particles suspended in a solvent and the particles are both charged and magnetized. The display of the invention prevents undesired movement of the particles in the cells. The magnetic force generated by the magnetic layer(s) eliminates the need to provide cells with a threshold voltage high enough to avoid the cross talk and/or cross bias effects. In addition, the dual switching mode allows the particles to move in the up/down direction as well as the planar direction, thus providing a multicolor display of high color quality at very low cost.
