Abstract
In one embodiment, a display element includes a first electrode; a dielectric layer having recessed regions therein over the first electrode; a second electrode disposed on the dielectric layer; and a fluid with colorant particles within the display element, wherein a voltage signal applied to the first electrode and the second electrode controls movement of the colorant particles such that a first voltage signal provides a first optical state by compacting the colorant particles into the recessed regions and a second voltage signal provides a second optical state by spreading the colorant particles in the fluid.
