摘要: | 具多功能模组之可携显示器,已逐渐成为现代生活不可或缺的必需品;而与使用者互动介面 结合,更是未來发展的趋势。整合于可携式显示电子产品触控模组,更可直觉性操控且节省产品 面积,而使轻薄可携式显示电子产品具有更广泛的运用。因此,本整合型计画拟藉由微奈米与软 性电子的技术,开发"類纸式软性触控显示器"。 本整合计画提出類纸式软性触控显示器,藉由微奈米制程、显示光学、软性电子、机械结构 分析及控制整合等技术,以发展整合软性显示、软性多点触控感测、软性系统控制等模组,并提 供系统资讯显示与触控操作功能。上述各技术可依据不同应用之需求,达成轻便薄型化、软性可 挠化、模组整合化、可携功能化的類纸式软性触控显示器,并运用于未來的智慧行动资讯生活。 本子计画利用具多孔性的阳极处理氧化铝(Anodic Aluminum Oxide: AAO)薄膜及奈米压印微 沟槽软性基板做为液晶显示元件的配向层。利用液晶分子会依基板表面结构排列之配向机制,无 机且具有奈米孔洞阵列的透明之AAO 薄膜具有很高的潜能可以作为液晶显示元件的配向膜。除 了利用多孔洞AAO 薄膜作为垂直配向层,本计画也将尝试使用奈米压印技术于软性基板上转印 出微沟槽结构作为水平配向薄膜。 最后本子计画将尝试于阳极处理氧化铝薄膜制作于ITO透明导电薄膜上及在奈米压印微沟槽 镀上ITO 透明导电薄膜,并制作出可电控的液晶显示元件。未來可以利用此一方式來制作可饶性 显示元件,并量测其电性反应或利用外加场來量测其锚定强度。 Recently, the portable displays with multi-function modules have become necessities in modern life. Combining the interactive interface is the future trend of portable displays development. By integrating the touch panel module with portable displays, the portable products could be more humanity and have wider applications. Thus, the major goal of this proposal is to develop a “flexible electronic paper-like display” by the micro/nano and flexible electronic technologies. By applying several technologies, including micro/nano fabrication, optical display, flexible electronics, mechanical structure analysis, and controlling systems integration, the flexible electronic paper-like displays are proposed in this proposal. Those displays provide the functions of information display and touching control by developing and integrating the modules of flexible display, flexible multi-point touch sensor and flexible system control on the devices. Base on different applications, those technologies could achieve a flexible electronic paper-like display with the merits of slimness, flexibility, modules integration and portability to apply in future life. In this sub-project, the porous anodic aluminum oxide (AAO) thin film and the nano-imprinted microgroove flexible substrate are used as the alignment layer of the liquid crystal displays (LCDs). Because of the alignment mechanism, the liquid crystal molecules tend to align on the surface homogenously or homeotropically depending on the morphology. The porous AAO thin film, inorganic and transparent film, is an excellent candidate of the alignment layer. On the other hand, the flexible substrates with the microscale groove imprinted by the nano-imprinting technology are used as the homogenous alignment substrates. Finally, in this sub-project, we develop the new process to anodize the aluminum thin film on ITO conductive layer and coat the ITO thin film on the grooved flexible substrate. The electrically controllable LCDs with the AAO thin film or the grooved flexible substrate as the alignment layer will be demonstrated in this sub-project. In the future, the electric performance and the anchoring strength can be measured by applying the external field. |
