新型高分子穩固扭轉雙穩態液晶元件之開發
指導老師:徐芝珊/林康平   組長:周彥仰   組員:周彥仰
雙穩態液晶元件擁有記憶的功能,在光電元件應用上,具有降低消耗功率之特性,進而達到節能減碳之效果。近年來,隨著綠能環保概念的提升,雙穩態液晶元件技術開發更加備受重視。本計畫擬在平行配向液晶盒內以雙頻液晶摻入微量手徵型材料及光可聚合高分子,藉由高、低頻電壓切換時引發的迴流效應(backflow effect)和高分子網絡穩固,開發具左、右旋扭轉180°之新型高分子穩固雙穩態液晶元件。本研究也將進一步探討手徵材料及高分子濃度對左、右旋扭轉穩定性之關係以及外在因素的改變下(例如紫外光之強度等)對整體液晶盒表現之影響。
In this project, a new type of bistable liquid crystal device having left- and right-hand 180 twisted molecular configuration as the stable states is proposed by incorporating chiral agent and photo-curable monomer in dual-frequency liquid crystals (DFLCs). While the stable left-hand twisted state is achieved by optimizing the thickness-to-pitch ratio, the right-hand twisted state is expected to be realized by the backflow effect of molecules and polymer stabilization. The effects of mixture concentration, including chiral and monomer, on the stability of two twisted states and electro-optical properties of this bistable device are discussed.
我們決定將壓電陶瓷晶片和鞋子做結合。
