This paper investigates the effects of indium tin oxide (ITO) powders on the driving voltage of polymer-dispersed liquid crystal (PDLC). The threshold voltage (V) and driving voltage (V) can be reduced through doping the ITO powders; in particular, the V 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.
本文研究了氧化铟锡（ITO）粉末对聚合物分散液晶（PDLC）驱动电压的影响。通过掺杂ITO粉末可降低阈值电压（V）和驱动电压（V）；特别是当ITO的重量比为1.5 wt.%时，V为5.8 V。研究了施加电压与PDLC关断时间之间的关系；施加电压越低，关断时间越短。在此基础上，提出了反向电压脉冲驱动方法；该驱动方法利用驱动信号来缩短PDLC的关断时间。
