摘要
在研究扭转丝状液晶电光曲线的基础上,通过测量TN型液晶的电场响应时间和驱动电场频率响应,提出了一种新的求解TN型液晶临界电压的方法,该方法可应用于精确测量液晶材料的某些基本特性参数.
Based on the experimental result of the electro-optic property of twsited nematic liquid crystal （TN-LC）, a deeper study of the TN-LC electro-optic response times is carried out. And a new method to approach the critical driving voltage is introduced by understanding the response times under different driving voltages.
