Abstract

Holographic polymer dispersed liquid crystals (H-PDLCs), which is one of promising material for LC display, when doped with nanoscale silver (nano Ag) exhibit a unique electro-optical response to frequency modulation. We established an equivalent circuit model for H-PDLC doped nano Ag gratings according to Maxwell–Wagner effect and calculated relaxation frequency for three concentrations of nano Ag. We found that the frequency modulation and doping concentration have a close effect on threshold driving voltage of H-PDLC gratings. It is experimentally shown that the lowest threshold driving voltage can be obtained when the driving frequency is located just around the recipe's dielectric relaxation frequency. It is possible to decrease the driving voltage of H-PDLC through selection of suitable driving frequency as well as via doping with appropriate concentration of nano Ag.
