利用参数空间方法,优化了反射式双稳态扭曲向列相液晶显示的对比度.对比度作为显示器的扭曲角、盒厚、与双折射率乘积的函数,通过绘制图线,可以清楚地看到具有高对比度的参数区域.还研究了两个双稳扭曲态的绝对透光率和色散.结果表明,当入射光为偏振光时,经过光学优化的反射式双稳态显示器可获得大于100的对比度以及100%的反射率.(N.13) Using the parameter space approach, the contrast of a reflective bistable twisted nematic liquid crystal display is optimized. Contrast As a function of the product of twist angle, cell thickness, and birefringence of the display, one can clearly see that High-contrast parametric regions, and also studied the absolute transmissivity and chromatic dispersion of the two bistable twist states.The results show that the optically optimized reflective bistable display achieves greater than 100 contrast when the incident light is polarized And 100% reflectance (N.13)
