The schematic and working mechanism of the low-powered dynamic plasmonic color display

Caption

The display panel, which serves as the anode of the battery, is composed of silica (SiO2) substrate, tungsten (W) conductive film (100 nm thick) and a magnesium fluoride (MgF2) insulating layer (30 nm thick) with periodic holes under the colorless ‘off’ state. Each pixel is composed of periodic holes with a given lateral period (p) and diameter (h). During the charging (electrodeposition) process, Li nanoparticles with diameter (d) generate colors as the ‘on’ state. These colors can be erased during the discharging process once Li nanoparticles are stripped off.
