摘　　要：本文提出了一个用于庞加莱球(Poincare (?)phere)方法最佳化超扭曲液晶显示器件参数的线性条件,我们应用这个线性条件用庞加莱球方法对膜补偿超扭曲液晶盒的参数进行了最佳化,获得了极好的补偿效果。分别对△nd=0.7,0.8,0.9,1.0μm的液晶盒进行了最佳化,得到了最佳化液晶盒参数,讨论了液晶盒厚度对显示特性的影响,将最佳化参效应用到实际液晶盒中去得列了很好的显示特性。The optimization of STN-LCD compensated by birefringent films (FSTN-LCD)has been performed with Poincare sphere method. A new common linearity condition in the optimization is proposed. A good compensation result is derived with the linearity condition. The effect of the thicknesses of LC cell is considered on the display characteristic in the case of △nd = 0. 7, 0. 8, 0. 9. 1. 0μm of liquid crystal. As △nd = 0. 8μm in the sandwich structure, the good display characteristic is obtained. The optimum parameters are applied to a real FSTN-LCD, a good display characteristic is obtained
