Dependence of the electro-optical properties of PDLC on the UV polymerization conditions and material parameters

초록

The electro-optical properties of polymer dispersed liquid crystals (PDLCs) depend on both dispersion structures and an alignment of liquid crystals that can be controlled by taking proper liquid crystals / polymer mixtures and process conditions. In this study, we suggest the optimum conditions for PDLCs in order to achieve excellent electro-optical properties. Under the optimized conditions, PDLCs of low threshold voltage less than 3.1 V, high contrast ratio more than 150 and negligible hysteresis were obtained.
