Optical fine-tuning was performed to reduce blue light leakage in a conventional reflective LCD and to obtain a reflective LCD with a better contrast ratio. Total light leakage in the dark state was examined by simulation, according to the optical axes of the half-wave plate and LC layer and the central wavelength used in the optical design of the LCD. The contrast ratio of the reflective LCD could be improved by more than fivefold, compared to that of a conventional LCD with a wide-band optical design, when the optical axis angles of the half-wave plate and the LC layer were 75° and 15.68°, respectively, and the central wavelength was 520 nm. Therefore, such optical fine-tuning can be applied to reflective LCDs to increase their contrast ratio.
进行了光学微调，以减少传统反射型液晶显示器（LCD）中的蓝光泄漏，并获得具有更好对比度的反射型LCD。根据半波片和液晶层的光轴以及LCD光学设计中使用的中心波长，通过模拟检查了暗态下的总光泄漏。当半波片和液晶层的光轴角度分别为75°和15.68°且中心波长为520nm时，与具有宽带光学设计的传统LCD相比，反射型LCD的对比度可提高五倍以上。因此，这种光学微调可应用于反射型LCD以提高其对比度。
