Paper Abstract

In this paper a simulation method for electro-optical volt-brightness characteristics of cholesteric liquid crystals has been demonstrated. This method allows to essentially decrease a duration of experimental investigation of transition processes in cholesteric materials. For modeling of electro-optical volt-brightness and volt-contrast characteristics we need to measure only a few specific critical and threshold voltage levels. Moreover there is no need to know any other physical and electro-optical properties of cholesteric materials. The example of modeling of electro-optical response of a ChLC from the initial transient planar state has been considered. These characteristics are very important for determination of various parameters for cholesteric displays and drive schemes at the dynamic addressing. Accuracy of proposed method is estimated by the comparison of volt-contrast characteristics of a ChLC obtained both by experimental measuring and proposed simulation method.
