摘要: | 藍相液晶是液晶當中最具有潛力的一種材料,因其亞毫秒級的響應時間,使藍相液晶顯示器成為下世代熱門的研究題目,但是藍相液晶顯示器有高操作電壓和低穿透率等問題,所以我們嘗試透過各種不同結構來優化藍相液晶的穿透率與操作電壓表現。
本論文將討論從本實驗室提出的中空六角型電極結構進行優化,嘗試調整現有電極結構以找到更佳的表現。本論文主要分成四部分,第一部分是將原有的二重中空六角型電極結構的厚度進行調整,分析電極厚度以及突起物高度對於原有結構的影響,第二部分延續第一部分的概念,考慮到結構與材料的穩定性問題,在其基礎上將之進行分層,並且討論把分層後的結構再次分為上下兩層(Double Side)的設計,最後,我們討論了在此模型下的多重中空六角型電極表現。第三部分沿用第二部分使用的多層結構模型,討論傳統藍相液晶IPS結構套入此模型後的表現,並分析討論與如何優化此結構,最後,於第四部分提出了改善關於第三部分的結構,即合成電極結構,並從各方面來討論這個新結構的問題。 綜上所述,在本論文中,我們提出了兩種新的電極設計,即“多層電極結構”和“合成電極結構”,以提高六邊形電極設計和傳統IPS電極設計的藍相液晶顯示器的性能。這些新設計在低工作電壓和高透光率方面的表現相當有前途。 Blue-phase liquid crystal is one of the most potential material among liquid crystals. In addition, due to its sub-millisecond response time, blue-phase liquid crystal has become a hot research topic for the next generation. However, the main problems of blue- phase liquid crystal displays are low transmittance and high operating voltage. Therefore, this thesis aims to optimize the T-V performance of blue-phase liquid crystal through the design of various electrode structures. This thesis will optimize the hollow hexagonal electrode structures proposed by our laboratory, and try to adjust the existing electrode structures for better performance. This thesis is divided into four parts. The first part of this thesis is to adjust the thickness of the original double hollow hexagonal electrode structure, and analyze the influence of electrode thickness and protrusion height on the original structure. Considering the stability of the structure and its materials, in the second part, the double hollow hexagonal electrode structure is layered, and we discuss the performance of multiple hollow hexagonal electrode under this model. The third part follows the multi-layer structure model used in the second part, discusses the performance of the traditional blue-phase liquid crystal IPS structure applied to this model, then analyzes and discusses how to optimize this structure. Finally, the fourth part proposes a new structure to improve the structure of the third part, namely the composite electrode structure, and discusses this new structure from various aspects. In summary, in this thesis, we have proposed two new electrode designs, namely “multi-layer electrode structure” and “composite electrode structure”, to improve the performance of blue phase liquid crystal displays with hexagonal electrode designs and traditional IPS electrode designs. These new designs show promising results with low operation voltage and high light transmission. |
