    • In one embodiment, a device includes a first display element including: a first electrode; a transparent dielectric layer having recessed regions therein over the first electrode; a halftoned second electrode opposite the first electrode; and a fluid with colorant particles between the first electrode and the second electrode, wherein a voltage signal applied between the first electrode and the second electrode controls movement of the colorant particles such that a first voltage signal provides a clear optical state by compacting the colorant particles into the recessed regions and a second voltage signal provides a grayscale optical state by attracting the colorant particles to the second electrode.
    • 在一个实施例中,一种装置包括第一显示元件,包括:第一电极; 透明电介质层,其在第一电极之上具有凹陷区域; 与第一电极相对的半色调的第二电极; 以及在第一电极和第二电极之间具有着色剂颗粒的流体,其中施加在第一电极和第二电极之间的电压信号控制着色剂颗粒的运动,使得第一电压信号通过压实着色剂颗粒提供清晰的光学状态 并且第二电压信号通过将着色剂颗粒吸引到第二电极来提供灰度光学状态。
