Electro-Optical Characteristics of STN-LC Cells Stabilized by a UV Curable Liquid Crystalline Polymer Material

Abstract

Recently the authers proposed a novel type of LCD which is based on the fieldinduced reversible transition from a SIN state with the twisted angle Φ to a RTN state with the twisted angle Φ-2π and vice versa. In this study, it is experimentally investigated how the doping of a UV curable liquid crystalline polymer into the chiral nematic LC material affect the electro-optical properties of the type of LCD mentioned above. As the results, the necessity of the application of holding voltage was removed and the transient characteristics was improved.
