对比度高及盒间隙大的双稳态扭曲向列相液晶显示

A New BTN LCD with High ContrastRatio and Large Cell Gap

用参数空间方法优化了（０， ２π）ＢＴＮ液晶盒的光学性质， 从而发现新的（０，２π）ＢＴＮ显示模式具有更高的对比度和更大的ｄΔｎ 值。实验表明，对比度最高可达２５０：１。在－ ８０°～＋ ８０°水平视角范围内对比度仍不低于８０：１。较大的ｄΔｎ

Optical properties of a (0,2π) transmissive BTN LC cell is optimized by parameter space method.Experimentally the high contrast ratios above 80 within -80° to +80° viewing angle ranges were first obtained.The highest contrast ratio is 250.The large dΔn makes this new BTN has the possibilities of large cell gap and low operating voltage.
