摘要：
Charge transport mechanisms and the complex impedance of liquid crystal displays are shown to have a strong effect on the electro-optical performance of passive and active matrix addressed twisted nematic and supertwisted nematic LCDs. The static and dynamic dependence of the LCD-performance on liquid crystal material parameters, especially on resistivity, LCD cell gap, surface aligning layers and electrode conductivity are shown. From the proposed model follow the conditions to achieve frequency independent LCD-operation.
