    Abstract: 在本論文中,我們探討PMMA微米球及銀微米球摻雜在高分子分散液晶(Polymer Dispersed Liquid Crystal, 簡稱PDLC)中的光電特性,藉由操作電壓的調變可以控制此元件從散射態轉為穿透態。
    PDLC光電性質優化之結果,我們利用摻雜5 wt%、直徑為3微米之銀微米球摻入PDLC中,操作電壓為44伏特且穿透態維持高穿透率70%,有效的降低操作電壓,減少元件操作時能源的損耗。最後,我們利用此結果,進行大尺寸之PDLC元件製作,增加實際的應用性。
    ;In this study, we investigate the electro-optic properties of Polymer Dispersed Liquid Crystal (PDLC) doped with PMMA and Ag microspheres. It can be switched from light scattering to transparent states by modulating the applied AC voltage.
    The study in this thesis is divided into three parts. In the first part, we discussed the influence of the weight ratio of LC and polymer on their electric-optic properties. In the second part of experiment, the required applied AC voltage to obtain transparent state can be reduced by doping PMMA microspheres whose diameter is about 3 um. In the third part of experiment, it is demonstrated that the applied AC voltage can be further reduced by doping with 3 m-diameter silver microspheres.
    By doping with 5 wt% 3 m-diameter silver microspheres into PDLC cell, the electro-optic properties of PDLC can be optimized. The operating voltage to provide 70 % transmittance is reduced to 44 V, so that the energy consumption can be reduced significantly. Additionally, we have also successfully demonstrated such a PDLC device having large panel size.
