Abstract

This paper investigates the effects of indium tin oxide (ITO) powders on the driving voltage of polymer-dispersed liquid crystal (PDLC). The threshold voltage (Vth) and driving voltage (Vd) can be reduced through doping the ITO powders; in particular, the Vd is 5.8 V when the weight ratio of ITO is 1.5 wt. %. The relationship between the applied voltage and off-time of PDLC has been investigated; the lower the applied voltage, the shorter the off-time. On this basis, the reverse voltage pulse driving method was proposed; this driving method uses the driving signal to reduce the off-time of PDLC.
