Research Abstract

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.
