合成電極應用於牆型及三維六角形結構之藍相液晶研究

Abstract

隨著科技日益的進步，液晶顯示器成為生活中相當重要的電子產品，其中藍相液晶被視為具有潛力的材料之一，藍相液晶因自組裝三維晶格結構，展現出高速響應、寬視角與製程簡化等優勢，但同時面臨高操作電壓與低穿透率等瓶頸。 研究中利用TechWiz 3D專業模擬軟體，建立多種電極結構模型，系統性分析傳統雙面藍相IPS結構、牆型電極、半牆型電極，以及三維多重中空六角形電極在穿透率與操作電壓上的表現，本論文透過三個部分探討合成電極於牆型及三維六角形結構之應用。第一部分，說明如何從雙邊IPS為基礎，透過改善操作電壓以及穿透率，調整電極排列結構形成合成電極結構。第二部分，改良傳統牆型電極結構高操作電壓及不透光區域問題，提出半牆型結構並結合合成電極設計，有效改善原本不透光區域的電場分布，顯著提升穿透率並大幅降低操作電壓。第三部分在三維六角形結構部分，研究證實多重中空六角形排列能兼顧高穿透率與低操作電壓，並進一步結合合成電極與結構優化，最終於六重中空六角形基礎上實現96.3%的高穿透率與較傳統設計降低52.5%的操作電壓。 整體而言，本論文透過合成電極結構改善原有之牆型及三維六角形結構，使結果兼具製程可行性與性能優勢，為藍相液晶顯示技術的實用化與未來發展提供了具體的創新路徑與理論依據。

With the rapid advancement of technology, liquid crystal displays have become indispensable in daily life, and blue phase liquid crystals are regarded as one of the most promising materials for next-generation displays. BPLCs, characterized by their self-assembled three-dimensional lattice structures, offer advantages such as ultra-fast response, wide viewing angles, and simplified fabrication processes. However, they still face challenges including high operating voltage and low transmittance. In this study, TechWiz 3D professional simulation software was utilized to construct and systematically analyze various electrode structure models—including traditional double-sided blue phase IPS structures, wall-shaped electrodes, half-wall electrodes, and three-dimensional multi-hollow hexagonal electrodes—in terms of their transmittance and operating voltage. This thesis explores the application of composite electrodes in wall-shaped and three-dimensional hexagonal structures by first improving the double-sided IPS structure through optimized electrode arrangement to enhance operating voltage and transmittance, then addressing the high operating voltage and non-transparent regions of traditional wall-shaped electrodes by introducing a half-wall structure combined with composite electrode design, which significantly improves the electric field distribution and overall transmittance while reducing operating voltage. Furthermore, for three-dimensional hexagonal structures, the study demonstrates that multi-hollow hexagonal arrangements can achieve both high transmittance and low operating voltage; by further integrating composite electrodes and optimizing the structure, a six-layer hollow hexagonal design achieves a high transmittance of 96.3% and a 52.5% reduction in operating voltage compared to traditional designs. Overall, this thesis demonstrates that the composite electrode structure effectively improves both the process feasibility and performance of wall-shaped and three-dimensional hexagonal structures, providing concrete innovative pathways and theoretical foundations for the practical application and future development of blue phase liquid crystal display technology.
