Abstract: An electrically tunable photonic crystal is developed utilizing crystalline colloidal arrays of high refractive index particles. Through modulation of the refractive index of the particle, and the applied electric field, both the bandwidth and position of the photonic bandgap could be tuned. Full color modulation with high optical quality is achieved, which paves a way to develop a novel reflective display.<br /> (Copyright © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.)
