Liang-Chy Chien
Biography
L.-C. Chien received his Ph.D. in Polymer Chemistry from the University of Southern Mississippi and joined Liquid Crystal Institute of 麻豆影院 State in 1988. His research interests include the studies of advanced functional materials, structures and surfaces as well as the innovative applications of such materials in displays electro-optical and photonic devices. He has published 150 articles, over 150 scientific proceedings and digest papers, edited 15 conference proceedings, three books and seven book chapters as well as 25 issued patents. He is a co-inventor of the bistable reflective cholesteric displays, polymer-stabilized liquid crystal display devices and technologies. Dr. Chien has been active in providing his services to professional society such as organizing and chair conferences as well as serve as an advisor or program committee on many international conferences.
His research in polymer and liquid crystal composites focuses on control of dimension, location and spatial distribution of phase separated polymers at the micro- and nano-scale on substrate surfaces or in the bulk. His research in polymer dispersed, modified and stabilized liquid crystal materials have led to the development of advanced electro-optical, photonic and display devices such as reflective bistable displays, electrically switchable color filters, electrically-switchable gratings, and blue phases based devices. The recently developed polymer dispersed and stabilized blue phases enable the fabrication of fast-switching spatial light modulators.
His research in tailoring liquid crystal materials to provide control over structure, surface, morphology, and processing have led to the development of new electro-optical devices. For examples, research in active and stimuli-responsive low- and high-molar-mass materials have led to the development of artificial muscles, light emitting devices and organic thin film transistors; Furthermore, the active materials whose functionality are used for controlled- assembly or self-assembly of dispersed nanoparticles to ordered structures to enhance desired properties of functional devices.
