摘要：详细介绍了胶体悬浮液作为一种显示用电泳液时的电学性能，分析了电泳颗粒的运动特征;针对目前有些文献中提到的介电泳现象以及利用介电泳现象制成的无源矩阵驱动方式，从理论角度进行了分析。指出介电泳现象在理论上确实存在，但是绝大多数的电泳液在显示时介电泳现象都很微弱，很难实现廉价、大面积的无源矩阵驱动;最后以一种电泳液为例测试了其反射谱，从实验角度验证了此结论, 并给出了最佳的驱动参数。

Abstract：In the present report, the authors studied the movement of pigment particles which decide the display status, enduced the equation of the motion and the expression of reflectivity, and estimated the value of the delay time. Combining the above theoretical conclusion with the experimental results, the authors discussed the feasibility of the passive matrix addressing of electrophoretic image displays, and provided good advice on how to acquire display devices of good quality.
