Experimental study of electrokinetic transport of microparticles in a confined microfluidic chamber

Electrophoretic displays, also known as EPD, are main examples of the E-papers category because of their paper-like appearance and low power consumptions. The information displayed in EPD is a result of the migration of charged pigment particles in a fluid containing an optically contrasting dye und...
