Abstract

The charged particle type display have characteristics of high contrast ratio and wide viewing angle, quick response time. We used the yellow(-) and the black(+) colored particles, which is respectively addressed to the cells of upper and rear panel by using electric field. Our independent addressing method has strong points compared to the mixed particle putting method. After addressing, we packaged two panels and did aging process, and then panel is driven by matrix method of four channel electrodes. Layers of particles are controlled by height of cell barriers and needed minimum two layers. When positive voltage is applied to the upper electrode, the yellow particles with negative charge move toward the upper substrate and the black particles with positive charge move toward opposite direction.
