摘要

利用TN-LCD液晶盒和不同的偏光片组合制作出电控调光镜样品，其外观具有半透明视觉效果。在施加电压后，从一侧看是黑镜子或雾镜子视觉效果，而从另一侧看则呈现为黑玻璃或毛玻璃的视觉效果。对样品进行电光特性测试，吸收-反射电控镜和散射-反射电控镜的阈值电压为2.4 V，饱和电压为5.2 V。吸收-反射电控镜的开态透过率为25.3%，关态透过率为0.7%；散射-反射电控镜的开态透过率为20.8%，关态透过率为10.1%。吸收-反射电控镜与散射-反射电控镜相比而言，前者的关态和开态具有良好的透过率对比变化，而后者的对比变化较差有待提高。运用琼斯矩阵理论对器件原理进行分析，最后对该制品的应用与产业化前景做出讨论。

Abstract

The electronically controlled switchable mirror samples was produced by using TN-LCD liquid crystal cell and different polarizers

which appearance had the translucent visual effect. From one side

it looked like a black mirror or a fog mirror

while on the other side it looked like a black glass or frosted glass. The electro-optical properties of the samples were tested. The absorption-reflection mirror and the scatter-reflection mirror had a threshold voltage of 2.4 V and a saturation voltage of 5.2 V. The absorption-reflection mirror had an on-state transmittance of 25.3% and an off-state transmittance of 0.7%. The scattering-reflection mirror had an on-state transmittance of 20.8% and an off-state transmittance of 10.1%. Compared with the scatter-reflection controllable mirror

the absorbing-reflecting electric mirror had a good contrast change in the off-state and the on-state

while the scatter-reflection had a poor contrast change. The principle of the device was analyzed by Jones matrix theory. The application and industrialization prospects of the product were discussed.
