A switchable light modulation device has an electrophoretic medium disposed between a first light transmissive electrode layer and a second electrode layer. The apparatus includes one or more apodization structures at the bottom of a cell containing an electrophoretic fluid that reduce light interference when the cell is in an on state and the structure is viewed by reflected or transmitted light through the apodization structures. 一种可切换光调制设备，其具有设置在第一光透射电极层和第二电极层之间的电泳介质。该设备包括在含有电泳流体的单元的底部的一个或多个切趾结构，当单元处于开启状态并且通过穿过切趾结构的反射或透射光观看该结构时，切趾结构降低光干涉。
