Abstract
A dual electrochromic/electroluminescent (EC/EL) device of at least one pixel includes an interdigitated electrode where an electroactive layer is dispersed on and between the digits of the two electrodes of the interdigitated electrode. The electroactive layer is in contact with an electrolyte layer that also contacts a third electrode. The device acts as an electroluminescence device when an electrical bias between the two electrodes of the interdigitated electrode is established. The device acts as an electrochromic device when the electrical bias is established between the combined electrodes of the interdigitated electrode and the third electrode.
