Physical properties of new liquid-crystal mixtures and electrooptical performance in twisted nematic displays

  title={Physical properties of new liquid-crystal mixtures and electrooptical performance in twisted nematic displays},
  author={Martin Schadt and Francisco Muller},
  journal={IEEE Transactions on Electron Devices},
Complete sets of measurements are reported of the elastic, dielectric, optical, and viscous properties of new liquid-crystal mixtures for twisted nematic displays. Their optical and capacitive threshold voltages were shown to be identical and were used to determine the twist elastic constants k22. The splay (k11) and bend (k33) elastic constants were measured using a novel phase sensitive capacitance bridge, The new mixtures consist of nematic and isotropic components belonging to different… CONTINUE READING
