Paper Abstract

The field hysteresis of the cholesteric-nematic transition (CNT) in mixtures with small (up to 2 weight%) maintenance of optically active material is being researched. It is shown that the relative magnitude of the loop of the hysteresis and (delta) U depends on the ratio d/P, (gamma) equals (root)K22/K33 and surface free energy. In the case of fixed magnitude of the surface free energy the ratio of constants of the elasticity and of the liquid crystal material gives a substantial magnitude of the constructive parameters of the display d/Po, which gives us a maximum of the (delta) U. The influence of the temperature dependence of the constants of the elasticity and step of the induced spiral on the temperature dependence (delta) U takes place.
