    • An electrophoretic display liquid composition for use in an electrophoretic display device that has a multiplicity of individual reservoirs, each containing the display liquid of two sets of particles dispersed in a transparent liquid system as well as at least one charge director dissolved or dispersed in the liquid system, or physically embedded on the surface of the particles or chemically bonded on the surface of the surface of the particles, the two sets of particles exhibiting different, contrasting color and different charging properties from each other. The charge director(s) is preferably a metal salicylate compound. The particles may be modified with charge controlling agents, and may also include a set of magnetic particles. The transparent liquid system may include two immiscible liquids having different densities with the sets of particles having densities in between the densities of the two immiscible liquids such that the particles rest at an interface between the two immiscible liquids.
    • 一种用于电泳显示装置的电泳显示液体组合物,其具有多个单独的储存器,每个储存器包含分散在透明液体系统中的两组颗粒的显示液体,以及溶解或分散在液体中的至少一个电荷引导剂 系统,或物理地嵌入在颗粒表面上或化学键合在颗粒表面上的两组颗粒彼此表现出不同的对比色和不同的带电性质。 电荷导向剂优选为金属水杨酸盐化合物。 颗粒可以用电荷控制剂改性,并且还可以包括一组磁性颗粒。 透明液体系统可以包括具有不同密度的两种不混溶液体,其中该组颗粒的密度在两种不混溶液体的密度之间,使得颗粒停留在两种不混溶液体之间的界面处。
