Dynamic color-generation structures provide higher resolution and scalability compared to the traditional pigmentation-based displays. The main roadblock to the wide adoption of structural colors is the fixed optical response after the realization process. To address this issue, several kinds of tunability mechanisms have been introduced including the implementation of plasmonic nano-antennas enabled by liquid crystals and plasmonic resonators exploiting stretchable materials. The chalcogenide phase-change mediums- (PCMs) based plasmonic structures offer advantages including flexibility, color durability, high resolution, cost-effectiveness, and CMOS compatibility. Herein, we propose an optimized PCM-integrated structure to generate a wide spectrum of colors.
