Novel stability enhancing technique for flexible LC display by using rigid spacer array and micro-contact printing

초록

In this work, the novel combined technology for maintaining constant gap between two flexible substrates was investigated. The self-gathering adhesive polymer structure to stick flexible substrates was generated by using the rigid columnar spacer array and a micro-contact printing (μCP) method. The proposed flexible liquid crystal display (LCD) structure showed fine optical properties as well as enhanced mechanical stability for flexible display application under assorted deformations. Moreover, this technique can easily inherit most advantages of traditional LCD technology such as low driving scheme, established process and LC mode selection freedom within a simple fabrication procedure. Therefore, this method can be a powerful candidate for realizing practical flexible display with enhanced mechanical stability and high performance.
