摘要: | 本論文主要介紹利用噴墨、親疏水性侷限效應、翻模技術製作不同屈光度之液晶微透鏡陣列。製程主要分為兩個部分:微透鏡陣列及液晶盒的組裝。製作微透鏡陣列的過程中,利用SU-8光阻自身疏水之特性,並使用噴墨機台製作微透鏡陣列,再使用翻模技術翻在玻璃基板上,若要再玻璃基板做出與矽基板曲度相反的微透鏡陣列,必須把第一次翻模出來的PDMS母模上在塗上一層PFOTS作為脫模劑,最後再一次地翻模,即可得到與第一次母模相同尺寸不同曲度之PDMS母模進而在玻璃基板得到凸或凹的微透鏡,再將透明導電高分子PEDOT:PSS均勻塗佈於微透鏡上形成曲面電極,再利用NOA81填平並且旋轉塗佈PVA作為配向膜,並搭配另一個ITO玻璃組裝成液晶盒,最後注入液晶形成液晶透鏡。我們成功利用噴墨機台和精密加工製作出直徑400微米與700微米之曲面型電極液晶微透鏡陣列,因為運用兩次PDMS翻模技術進而製作出正與負屈光度之液晶微透鏡。 In this research, the fabrication of the liquid crystal microlens arrays with positive and negative power was demonstrated. The fabrication process consists of two parts: the fabrication of microlens arrays and liquid crystal cell. There are some steps in the process of fabricating microlens arrays: the hydrophilic confinement effect, the inkjet printing, and the replication process which was used to fabricate micorlens arrays on the glass substrate. However, in order to make the microlens arrays with different curvature at the same aperture size, it would be necessary to coat a layer of PFOTS as release agent at the first PDMS mold. Finally, we could get the mold opposite of the first. After completing the microlens arrays, PEDOT:PSS was coated on the microlens arrays as a curved electrode and flatten by NOA81. Lastly, we assembled the sample with another ITO glass to form the liquid crystal microlens arrays. We have successfully using inkjet printing and precision machining to fabricate a curved electrode liquid crystal microlens arrays with diameters 400 μm and 700 μm on the glass substrate. |
