Abstract

We have presented a bistable transflective cholesteric light shutter. The shutter contains dual-frequency cholesteric liquid crystals that incorporate a photocurable monomer. The electro-optical properties and optical microscope images of the shutter were examined. Good correlations between the cholesteric textures and optical properties of the shutters were obtained. The shutter was switched into a wide-band homogeneous transmission mode by a low frequency voltage pulse, and into a selective reflection mode using a high-frequency voltage pulse. The concentration of the monomer apparently affected the electro-optical characteristics of the shutter.

摘要

我们展示了一种双稳态透反式胆甾型光快门。该快门包含掺入光固化单体的双频胆甾型液晶。对快门的电光特性和光学显微镜图像进行了检测。获得了快门的胆甾型织构与光学特性之间的良好相关性。通过低频电压脉冲将快门切换到宽带均匀透射模式,通过高频电压脉冲将其切换到选择性反射模式。单体的浓度明显影响快门的电光特性。
