Ferroelectric Liquid Crystal-Polymer Composites: A Novel Display Material

Abstract

Liquid crystals constitute an important class of display materials used in liquid crystal display (LCD) devices. Although, these materials were discovered over a century back (1988), but they gained importance about mid 1970’s when used in seven segment display devices like digital watches, calculators etc. Since then, the subject became a household name considering the market potential and varied use in consumer electronics. At present, LCD’s constitute about 68% market share in display industry starting from small seven segments to high definition projection displays. Behind this technological development, liquid crystalline materials play a very important role. In this talk, we shall discuss the work being carried out in our research group at TIET in this subject. We will also deliberate on the development of ferroelectric liquid crystal-composite materials and physics behind the LCD technology.
