| 摘 要： | 本文在叶伯琦(Pochi Yeh)扩展琼斯矩阵的基础上,推导出在斜入射情况下扭曲向列型液晶显示器(LCD)电光特性计算公式,并与Berreman的4×4矩阵、Lien的扩展琼斯矩阵进行了数值比较结果表明,运用本论文的计算公式得到的结果要比Lien的更接近于用Berreman 4×4矩阵得到的结果,并且本文推导得出的公式具有运算量小,直接和简洁等特点. |

| Abstract: | Detailed formulas were derived using Yeh′s formulation of the extended 2×2 Jones matrix and applied to twisted nematic liquid crystal displays(LCDs)at oblique angles of incidence.Numerical comparisons of this extended Jones matrix method with the exact 4×4 Berreman matrix and with the extended Jones matrix of Lien are presented.The different extended Jones matrix formulations differ in their approach to boundary conditions matching between the model birefringent layers.We show that the Yeh′s version is a more accurate approximations to the full 4×4 matrix.This extended Jones matrix method is fast,direct and simple.It is also physically more intuitive. |
