Abstract: Electronic inks have been developed for each primary color to serve as the imaging fluids for novel electro-kinetic display (EKD) technology. EKD uses in- plane optical effects and out of plane switching fields to switch between color and clear states, allowing a stacked approach of color layers for a full-color display. The need for compaction into small volumes to achieve a clear state and repeated cycles of spreading and compaction creates challenges for the stabilization and charging of colorant particles. Surfactants play a critical role in determining system behaviors. This paper reports on the latest findings of surfactant influence on optical switching and bistability characteristics of display performance for some proprietary surfactant formulations.
