摘要
In this paper, doping liquid materials to enhance the electro-optical ( EO) properties of twisted nematic liquid crystals ( NLCs) was presented. Two aromatic hydrocarbon (AH) liquids, toluene and 1-methylnaphthalene, were chosen as dopants in order to lower the driving voltage and response time of the NLCs. A 18% decrease in driving voltage and response time was achieved by doping 10 wt% toluene into NLCs. The main reason of this phenomenon is due to a large amount of reduction in the rotational viscosity of AH liquids doped NLCs. This method provides an easy and potential choice for applications in various LC display systems. (C) 2014 Optical Society of America
