| 摘 要： | 我们测量了介于“理想”正交偏光片组之间的VA和JPS液晶盒在不同温度下的固有漏光。在温度低于向列相到液态的转变（清亮点）温度时,测量到的VA液晶盒固有漏光与温度变化无关,相反,JPS液晶盒无论是o光模式还是e光模式结构中固有漏光都随温度的增加而增加。我们推导出基于向列相液晶指向矢涨落引起光散射的理论公式,以解释我们的实验结果。 |

| Abstract: | We have measured intrinsic light leakage of VA and IPS LC cells between"ideal" crossed polarizers as a function of temperature. The measured intrinsic light leakage of VA LC cell were independent of temperature up to the nematic-to-isotropic transition temperature in comparison to a increasing light leakage as temperature increases in IPS LC cells arranged in either o-mode or e-mode configuration. We have derived equations based on light scattering caused by fluctuations[1] of nematic LC director to explain our experimental results. |
