导出了一个动态模型，解释了表面稳定铁电液晶单元的主要寻址特性，并再现了最复杂的寻址模式。根据该模型，可以计算最佳寻址波形及其速度和对比度限制，并将其与可测量的电池参数相关联。尽管该模型很简单，但获得的结果非常令人鼓舞。现在似乎理解了具有给定开关脉冲区域的单元的“可寻址性”对先前被忽略的属性的依赖性。速度和对比度的限制现在可以与寻址相关；相关的可测量细胞特性和变分分析技术可用于导出优化的行和列波形。<<ETX>>
A dynamic model was derived explaining the main addressing properties of the surface stabilized ferroelectric liquid crystal cells and reproducing even the most complex addressing modes. From the model, optimal addressing waveforms and their speed and contrast limitations can be computed and related to measurable cell parameters. The results obtained with the model are very encouraging, in spite of its simplicity. The dependence of the 'addressability' of a cell featuring a given switching pulse area on previously ignored properties seems now understood. The limitations in speed and contrast can now be related to addressing; relevant measurable cell properties and variational analysis techniques can be used to derive optimized row and column waveforms.<<ETX>>
