摘要: 
電濕潤光閥(Electrowetting Light Valve)為近幾年來新發展出的顯示技術,電濕顯示器(Electrowetting Display)利用材料間表面張力(Surface tension)的差異,將油墨夾於水滴與恐水性(Hydrophobic)表面的絕緣層之間,再以靜電力來改變水滴與油墨的狀態,進而控制出光亮,具有反應時間快(<10ms)、廣視角、簡單製程等優點,且顯示型態與cell-gap無關,就電子紙(e-paper)顯示器而言,電濕潤顯示技術為目前最具優勢的技術,而在未來更有機會能取代TFT-LCD中液晶的功能。
本研究首先探討材料對於電濕潤光閥特性的影響,及討論電濕顯示畫素的製程與特性分析,接著進行水滴電濕潤現象的實驗,最後,以微影(Photolithagraphy)製程製作出多區塊圖形的電極,觀察以此方式驅動下,油墨狀態是否如預期隨著電極的圖形而有所改變,並利用光學量測系統檢測多區塊圖形畫素是否對反應時間造成影響。

Electrowetting light valve(ELV) is a novel display technology developed in few years ago. For utilization surface tension between different materials, the color oil naturally locates as a film between the droplet and the hydrophobic insulator. By changing the magnitude of electrostatic, color oil spread or contracted in this small system. The light absorbed or passed through the pixel depends on the state of the colored oil. The advantage of ELV are fast response time(<10ms), wide view angle, and less process. The insensitivity related to cell-gap thickness is excellent advantage when the electrowetting technology is used in flexible display. In the future, ELVs have high possibility to replace the liquid crystal in TFT-LCD structure.
This thesis investigates the materials, structure and all characteristics of ELV. Both contact angle and surface tension of materials are measured by contact angle measurement. The photolithography processes are developed to define each pixel as pixel grid, and electrodes of both common and multi-domain pixels. Optical parameters, response time ELVs' pixels are measured by using CCD camera and optical measurement system. For fast response time, multi-domain unit pixel that pixel electrode is divided into two and four domains, is designed and investigated each path when oil is contracted into different domains.
