Fig. 4: Feasibility of a multiple-color display.
a Images and b reflection spectra at different states for the eMAPD with the cyan droplets containing red particles. The States I, II, and III are obtained at U of 0, 14, 42 Vrms, respectively, at f = 400 kHz. c Images and d reflection spectra at different states for the eMAPD with the magenta droplets containing green particles. The States I, II, and III are obtained at U of 0, 10.6, 35.4 Vrms, respectively, at f = 400 kHz. e Representative eMAPD panels showing multiple colors and contrasts for “S”, “C”, “N”, and “U” letters based on the yellow-blue and cyan-red system driven at 14 Vrms and 400 kHz. Scale bar, 2.5 mm
