Metasurfaces have recently been used for multichannel image displays with pixel-size lower than a wavelength, which indicates the potential application in ultracompact anticounterfeiting high-density and hidden information. However, current metasurfaces applied are based on sophisticated nanostructure design or at cost of giving up some controls optical transmission matrix to encode multiple information channels. That is, overall degrees freedom offered by these "zero-sum game". Here,...
