蓝相液晶作为一种新型的液晶显示材料，具有宽视角、响应速度快、制作简单等优点，从而成为光电显示领域的一个研究热题。基于平均场理论，从液晶分子相互作用势出发，计算了液晶蓝相BPI的螺距，并讨论了势参数、螺距与约化温度的关系，模拟结果与实验相符，且模拟数值结果表明通过对势参量的调整将会改变BPI的螺距等重要特性。研究可以为蓝相成因的微观解释提供一定的理论参考。

As a novel type of liquid crystal display materials, the blue phase of liquid crystal with wide viewing angle,fast response,simple fabrication process,etc.,has become a hot topic in the filed of optoelectronic display.In this paper,the pitch of liquid crystal blue phase I (BPI)was calculated based on the mean-field theory.The relationship between the potential parameter and BPI’s pitch,as well as BPI’ s critical temperature, were discussed. The calculated results were compared with the experi-ments’.The well-matched comparison between the results and the experiments’ shows that the regula-tion of potential parameter will change critical temperature and pitch of BPI. This paper will give refer-ences for microcosmic explanation of BPI’s forming.
