| Summary: | 碩士 === 國立中山大學 === 光電工程研究所 === 96 === The Guest Host Mode of LCD is doped the dichroic dyes in liquid crystal and it have anisotropic absorbefacient. This operation mode can produce dark or brightness to achieve display target by the electric field and this can operate in the non-polarizer type to achieve high reflectance. Because of market requirement in the e-paper display, so the reflective LCD by the guest host mode is a focal once again.
In this study, we will doped the black dichroic dyes in liquid crystal and than we fill into the homogenous alignment cell by difference rubbing direction and homeotropic alignment cell to investigate the optical-electric characteristic in the non-polarizer and polarizer type, because in the difference alignment condition can influence the behavior of dichroic dyes, and we fabricate the double cell to improve the optical-electric characteristic.
The reflective type guest host display still have many research space, like dope the dichroic dye in PDLC(polymer dispread liquid crystals) or cholesteric liquid crystal to achieve flexible and bistable characteristic.
