Publication number: 20120127560Abstract: An electro-optical display includes colorant particles that are suspended in a carrier fluid. The colorant particles are controlled by three different types of electrodes. An exposed electrode acts on the colorant particles in an electrokinetic manner by compacting the colorant particles. A passivated electrode acts on the colorant particles in an electrostatic manner by holding the colorant particles once compacted. A reference electrode attracts the colorant particles to compaction areas.Type: ApplicationFiled: November 22, 2010Publication date: May 24, 2012Inventors: Jeffrey Todd Mabeck, Gregg Alan Combs, Tim R.
