A Hysteresis-free Polymer-stabilized Blue Phase Liquid Crystal

Our experimental results indicate that UV curing conditions dramatically affect the electro-optic performance of a polymer-stabilized blue phase liquid crystal (PS-BPLC). In an IPS cell, the UV light direction, wavelength, and dosage influence the polymer network distribution, operation voltage and hysteresis. By using a longer UV wavelength, we demonstrated a hysteresis-free PS-BPLC. Author Keywords blue phase; polymer network; UV curing; hysteresis. 1
