摘要

由于在不透明状态下各方向的空间相位差很大，我们使用具有均匀排列(HA)液晶(lc)的衍射智能窗口进行了演示。该光栅单元具有较高的雾度值(88.57%)，比先前报道的垂直排列(VA)光栅单元高1.16倍，因为该光栅单元具有比垂直排列(VA)光栅单元更高的扭曲角。我们提出的HA光栅单元可用于各种智能窗口应用。

Diffractive liquid crystal device for privacy window with a low operating voltage

We demonstrate using a diffractive smart window with homogeneous-aligned (HA) liquid crystals (LCs) owing to the large spatial phase difference in all directions in the opaque state. The proposed grating cell had a high haze value (88.57%), which was 1.16 times higher than the previously reported vertically aligned (VA) grating cells because the proposed grating cell had a higher twist angle than what the VA grating cell had. Our proposed HA grating cell can be used in various smart window applications.
