We propose an alignment method for the near-zero pretilt angle of liquid crystals (LCs) using polyimide films doped with a UV-curable polymer. The near-zero pretilt angle can be obtained by UV curing of reactive mesogen monomers mixed with planar alignment material while a vertical electric field is applied to an LC cell assembled after the rubbing process. We demonstrated that the pretilt angle can be decreased from 2.390° to 0.082° by employing the proposed method.
我们提出了一种使用掺杂有紫外光固化聚合物的聚酰亚胺薄膜来实现液晶（LC）近零预倾角的取向方法。当在摩擦过程后组装的液晶盒上施加垂直电场时，通过对与平面取向材料混合的反应性液晶基元单体进行紫外光固化，可以获得近零预倾角。我们证明，采用所提出的方法，预倾角可从2.390°降低至0.082°。
