A flexible electronic paper in full color is realized by plasmonic metasurfaces with conjugated polymers. An ultrathin large‐area electrochromic material is presented which provides high polarization‐independent reflection, strong contrast, fast response time, and long‐term stability. This technology opens up for new electronic readers and posters with ultralow power consumption.
Ultrathin plasmonic metasurfaces create bright colors when illuminated by white light. On page 9956, A. B. Dahlin and co‐workers show that by growing a conductive polymer on the nanostructures, they can be electrically switched between a “color on” and a “color off” state. This opens up the way for new types of low‐power flexible electronic paper displays.
