条纹域的外观受到各种电池条件的强烈影响，例如厚度，施加电压和表面对齐。在这项工作中，我们采用混合表面对准来研究非对称表面锚定下条纹域的外观。观察到条纹方向随电池厚度和外加电压的变化而连续旋转，具有独特的衍射光栅电位。研究还发现，对于任何尺寸的单元，旋转响应时间总是几秒，因为大面积旋转是通过在其边界上与缺陷产生-消除过程相关的小多畴旋转的总和来实现的。
The appearance of stripe domains is strongly affected by various cell conditions such as thickness, applied voltage, and surface alignment. In this work, we adopt hybrid surface alignment to investigate the appearance of stripe domains under asymmetric surface anchoring. It is observed that the stripe direction rotates continuously according to the cell thickness and applied voltage, which has potential as a unique diffraction grating. It is also found that the rotational response time is always several seconds for any size of cell, because a large area rotation is achieved by the sum of small poly domain rotations related to defect creation–extinction processes on their boundaries.
