指導老師:徐芝珊/陳世麟   組長:陳彥瑜   組員:陳彥瑜

相分離層化高分子薄膜為一形成於液晶盒內的複合結構,利用其具有壓縮液晶層的特性,該技術可以製作更薄的液晶盒,使元件的光電特性更具可塑性。在軟式顯示器的應用上,層化高分子薄膜可視為配向層,因其製程溫度低,故可避免塑膠基板在高溫烘烤下之形變。此外,高分子網絡對於外加應力有著極佳的韌性,可有效地保護彎曲基板對液晶層造成的破壞。
本研究結合PSCOF技術與膽固醇液晶結構提出新型軟性反射式彩色顯示器之概念。實驗中我們利用照射紫外光製作層化高分子薄膜/膽固醇液晶複合結構。另一方面,基於膽固醇液晶具有布拉格反射的特性,我們藉由添加不同濃度的對掌性分子,來改變膽固醇液晶反射光的波長,而調配出能反射三原色(紅、綠、藍)的樣品,達到彩色顯示的效果。
Phase Separated Composite Film (PSCOF) is formed hybrid structure in the cell. Using the property of compressing LC layer, this development can be used in making thinner cell to make its photoelectric property more plastic. The employment of the flexible display, Phase Separated Composite Film is regard as polymide. Because of its low temperature in the process, we can avoid the deformation of plastic substrate baking in the high temperature. Furthermore, polymer layer have greater toughness to the external force to protect bending substrate, which results in destroying the LC layer effectively.
A reflective cholesteric liquid crystal (CLC) display is demonstrated using Phase Separated Composite Film (PSCOF) method. After using the UV illuminate the polymer to let it polymerizes on the top substrate, the LC layer is formed between the polymer and the underneath substrate. As a result, PSCOF can be used to the thinner cell to make the flexible display owing to the flexible polymer. The multi-domain PSCOF-based CLC display is easy to fabricate and suitable for use in a flexible plastic display.
我們決定將壓電陶瓷晶片和鞋子做結合。
