Effect of Dielectric Anisotropy on Optoelectric Characteristics of Ferroelectric Liquid Crystal

  • A circuit model of ferroelectric liquid crystal(FLC) was proposed to study the effects of biaxial anisotropy on switching time,characteristic time,characteristic voltage and polarization reversal current,and those of ferroelectric torque and dielectric torque on light transmittance.The results indicate that the delay time has the minimum value as the drive voltage amplitude varies,and the characteristic time(voltage) increases(decreases) as the biaxial anisotropy increases.When the value of biaxial anisotropy is large enough,the effect of dielectric torque exceeds ferroelectric torque;the corresponding polarization reversal current becomes unipolar rather than bipolar;and the alternating change in light transmittance between "bright" and "dark" vanishes,and the peak value of light transmittance decreases gradually.
