为了提出使用非偏振UV光的光刻液晶（LC）器件，提出了使用光掩模在光致配向层上进行单步激光图案化以实现LC分子与周期性图案化衬底接触的平衡构型。这些图案由在0.5 μm量级的亚微米尺度上交替的随机平面和垂面锚定的条带形成。提出了两种可能的构型的微图案化液晶盒，其可以通过将以交替的随机平面和垂直取向形成的微图案化表面与平面或垂直取向表面组合来获得。沿着研究了这两种模型的取向特性以及微图案化的双折射液晶盒的微观开关行为。
To come up with a bistable liquid crystal (LC) device using unpolarized UV light, single-step laser patterning on a photoalignment layer using a photomask was proposed to achieve an equilibrium configuration of LC molecules in contact with a periodically patterned substrate. The patterns were formed by stripes of alternating random planar and homeotropic anchoring on a submicrometer scale in the order of 0.5 μm. Two possible configurations of bistable LC cells that can be obtained by combining a micropatterned surface formed with alternating random-planar- and homeotropic-alignment with planar- or homeotropic-alignment surfaces were proposed. The alignment properties of the two proposed models were investigated, along with the microscopic switching behavior of micropatterned nematic LC cells.
