liquid crystal electric paper with optically writing and erasing mode caused by anchoring change

我已经研究了一种液晶纸，该液晶纸可以通过控制取向膜的锚定强度而不施加电压来显示单色图像。我们使用聚乙烯基肉桂酸酯作为取向膜材料，并且可以通过改变锚定强度来进行光学写入和擦除，但不能重写。我还数值分析了液晶取向和透射分布。讨论了区域覆盖调制的特性，阐明了一种适用的多域调制方式。

I have studied a liquid crystal paper which can display monochromatic image by controlling an anchoring strength of a alignment film without an applying voltage. We use a polyvinyl-cinnamate as an alignment film material and can optically write and erase by changing the anchoring strength, however not re-write. I have also numerically analyzed a liquid crystal orientation and transmission distribution. Properties of area coverage modulation are discussed and a suitable multi domain mode is clarified.
