<title>Plastic liquid crystal displays from conducting polymer</title>

Abstract

In a conventional liquid crystal display device (LCD), glass substrates coated with an indium tin oxide layer are typically used for the application of an electric field to the liquid crystal material. For many applications including cockpit and avionic display applications, there is a need for a LCD with plastic substrates. We have demonstrated for the first time the operation of a fully multiplexed plastic LCD using conducting polymers as the substrates and the newly developed reflective cholesteric display technology. The resultant display has several features like light weight, low power consumption, increased ruggedness, bistability, sunlight readability and flicker-free operation. The functioning of the conducting polymer-based LCD is demonstrated and the features that make it attractive for cockpit applications are discussed.
