Structural diagram of metapixels
Structural diagram of metapixels (subpixels). The metapixels consist of WO3 nanodisks and a reflective layer on a glass substrate. By varying D and W of the nanodisks, the metapixels can selectively reflect RGB colours. Further tuning of T enables the generation of hybrid colours such as CMY. As WO3 is electrochromic it can undergo reversible electrochemical reactions, yielding reflectance modulation of the WO3 nanodisks, enabling an RGB video display.
