dc.description.abstract | 藍相液晶顯示器為下個世代相當熱門的研究題目,因為其亞毫秒的響應時間,它可以藉由場色序式液晶顯示器來提高動態圖像品質以及顯示器的解析度與光效率,但藍相液晶顯示器的高操作電壓與低穿透率為首要解決的問題,本論文藉由電極結構的設計改善藍相液晶顯示器的高操作電壓與低穿透率問題。
本論文提出二個新的電極結構設計,分別是源自於吳思聰教授和其團隊所提出的二維enhanced protrusion電極結構以及本實驗室所提出的三維凸起電極結構。在二維雙層電極結構中,我們藉由增加電場穿透深度來降低其操作電壓,而在三維雙邊電極結構中,我們憑藉上基板電極的水平電場來改善三維凸起物電極在對角線的穿透率失效區,而在結構參數優化完成之後,我們發現二維雙層電極結構可以有效改善高操作電壓的問題,而三維雙邊電極結構可以改善三維凸起物電極的低穿透率的問題。 | zh_TW |
dc.description.abstract | Blue-phase liquid crystal display is a very popular research topic for the next generation. Because of its sub-millisecond response time, it can improve motion image quality and also improve the resolution and optical efficiency through field sequential color (FSC) scheme. However, the primary problems of blue phase liquid crystal are low transmittance and high operation voltage. This thesis aims to reduce the operating voltage and increase the transmittance of blue-phase LCDs by the design of electrode structures.
This thesis proposes two new electrode structure designs, which are derived from the two-dimensional enhanced protrusion electrode structure proposed by Professor S.T Wu and his team, and the three-dimensional protrusion electrode structure proposed by our laboratory. In the two-dimensional double-layer electrode structure, we reduce the operating voltage by increasing the penetration depth of the electric field. In the three-dimensional dual-side electrode structure, we improve the transmittance of the diagonal area of the electrode by the horizontal electric field of the upper substrate’s electrode. After the optimization of the structural parameters, we found that the two-dimensional double-layer electrode structure can effectively reduce the operating voltage, and the three-dimensional dual-side electrode structure can increase the transmittance of the three-dimensional protrusion electrode. | en |
