- Abstract
- The electro-optic properties of PDLC films were investigated by process conditions such as PDLC injection temperature, UV curing temperature and UV power. The mixture of liquid crystal (TL205) and the prepolymer substituted 1,6-hexanediol diacrylate (HDDA) for trimethylolpropane triacrylate (TMPTA), and the crosslinker in PN393 was used for PDLC formulation. The contrast ratio and driving voltage of PDLC films were mainly affected by UV curing temperature, rather than by the injection temperature. The film that was prepared at a relatively low UV process temperature revealed a good contrast ratio at a low driving voltage.
