摘要
利用差分方法通过解二维非线性偏微分方程,得到了液晶盒中液晶指向矢的空间分布,在此基础上,进一步得到了透射光强的分布,我们发现,一方面,电极边缘处透射光强分布不同于电极中间处;另一方面,其它条件不变,逐渐减小电极间间隙宽度,会造成液晶屏相邻像素之间难以分辨。通过分析知道,这是由电极的边缘效应和VA显示模式自身电光特性共同作用的结果。
The spatial distribution of directors within the LCD cell is calculated by means of solving two-dimensional nonlinear partial differential equations using difference method. Based on the spatial distribution of directors, we get the spatial distribution of intensity. So we know, in one hand, the spatial distributions of transmitting light intensity are different from those in the center of the electrode. In other hand, with the same other conditions, but reducing the width of the gap of the electrodes gradually, the optical intensity becomes analogous to each picture-element electrode connected as a whole without gaps. The two phenomenons are owning both to the electrode＇ s edge effect and the voltage-dependent transmittance relationship.
