The development of ferroelectric LCDs for display applications

Abstract

Abstract— Ferroelectric LCDs have shown promise for use in high‐speed or highly multiplexed flat‐panel displays. Before ferroelectric liquid‐crystal technology could be implemented in practical devices, a number of significant problems had to be overcome. It is believed that all the remaining problems have now been removed, leaving the way open for large‐scale production of computer displays and the potential for larger devices to rival competing active‐matrix and supertwist display technologies. This paper will review the significant developments of FLCDs, illustrated by examples from both CRL and other laboratories.

High contrast chiral nematic liquid crystal device using negative dielectric material

“…However, these LCs are notoriously difficult to align uniformly over large areas. 9,10 Chiral nematic displays have been widely studied ͑see, e.g., Ref. 11͒, using both conventional electrodes and inplane electrodes.…”
