Highly Bendable Liquid Crystal Displays with Plastic Substrates for Mobile Applications

In this work, we report on pixel-encapsulated (PE) flexible LCD with a multi-functional elastomer substrate in the vertically aligned configuration. The elastomer substrate, fabricated by a replica molding technique, provides the vertical alignment for the LC molecules without any surface treatment, pixel encapsulating walls to maintain the uniform cell gap as spacers as well as to prevent the LC flow in the bent state, and mechanical stability. It is found that our PE flexible LCD preserves well the EO performances in a highly bent environment
