Dielectric characterization and voltage holding ratio of blue-phase cells
Phase behaviors of BP are studied by temperature-dependent dielectric spectroscopy. Phase transition temperatures are identified with derivatives of the permittivity. A circuit design with 30-V data-line voltage is proposed to evaluate VHR of a PSBP. The VHR of a PSBP cell is primarily determined by the nematic host used.
