Preparation and characterization of nano particles induced vertically aligned liquid crystal

Abstract

With the increasing demand of liquid crystal displays (LCDs) over past few decades, the need of vertically aligned liquid crystal (VALC) display devices have been increased tremendously because VALC displays possess much improved morphological and electro-optical (E-O) performance which is the prior demand of users. Consequently, several researchers have studied nano-particles (NPs) doped VALC devices and reported enhanced E-O characteristics of LCDs with the reduced threshold and operating fields. However, the manufacturing processes of these VALC devices are still complicated and more time consuming due to involvement of different process steps like polyimide coating, high temperature baking and rubbing etc. newline
