The increasing demands for display devices with low power consumption and outdoor readability have stimulated comprehensive research into reflective displays that employ tunable photonic crystal technologies. Recently, color tuning of electrophoretic crystalline colloidal array (CCA) has been demonstrated as a promising candidate for full color reflective display. To overcome problematic features of water in electric field, non-aqueous liquid medium is required. Herein, CCA formed from core-shell PMMA/poly(t-butyl methacrylate) microspheres was fabricated, which was stabilized by the inverse micelles of sodium di-2-ethylhexyl-sulfosuccinate in an iso-paraffinic fluid. A highly charged all-organic CCA was found to exhibit full-color tunability with a thousand-fold reduction in the operating current under a voltage bias in comparison with the current in an aqueous system. |
