We are working on developing new types of reflective (passive) displays in color, with the main motivation to provide energy savings compared to conventional emissive displays (LED and LCD ). Such “electronic paper” technologies do exist (e.g. Amazon Kindle) but the image quality and refresh rates are poor, which limits their broad use. Our approach is to combine structural colors based on plasmonic nanostructures with electrochromic materials, both inorganic and organic. Since our initial work,[1] our group has focused on improving brightness and contrast, using primary colored (RGB) structures² or tunable cavity resonances.[3] Recently we also achieved video speed switching using organic electrochromism.[4]
