| 发明名称 | Electrophoretic dispersion | ||
| 摘要 | The present invention is directed to an electrophoretic dispersion, in particular, an electrophoretic dispersion comprising uncharged or lightly charged additive particles for improving bistability of an electrophoretic display. The average diameter of the additive particles is about 1% to about 25% of the average hydrodynamic diameter of the charged pigment particles. | ||

| 主权项 | 1. An electrophoretic dispersion comprising charged pigment particles and uncharged or lightly charged additive particles dispersed in a solvent or solvent mixture, wherein a) the average diameter of the additive particles is about 1% to about 25% of the average hydrodynamic diameter of the charged pigment particles, and b) the additive particles are excluded from depletion zones around the charged pigment particles to induce flocculation of the charged pigment particles. | ||
