    Abstract: 本論文針對吳宥翰學長製作的大面積照明元件所觀察到的細暗紋、大型暗塊、濕膜揮發不均等問題進行探討且提出有效的製程與設備改良方法,並建立自調式刮刀膜厚預測模型,最後製作出無細條紋與大型暗塊的照明元件。 細暗紋的成因為刮刀表面不平整,在多層塗佈時,刮塗掉上一層薄膜,在元件點亮後,在運動方向呈現整面約70 μm的細暗紋;為此我們將刮刀更換為刀鋒平整的矽晶圓刮刀,解決了此細暗紋問題。大型暗塊與濕膜揮發不均乃是因為加熱系統的溫度分佈不均導致溶液有表面張力梯度,產生Marangoni effect而出現濕膜揮發不均的現象,為此我們改善紅外線燈管的溫度均勻度,有效抑制Marangoni effect對膜厚均勻度的影響。並且在單層塗佈發光材料Poly[9,9-dioctylfluorenyl-2,7-diyl] – End capped with N,N-Bis(4-methylphenyl)-aniline(PFO)在40  225 mm範圍內,達到平均膜厚為103 nm,標準差僅3.94 nm,膜厚變異百分比3.83 %的高品質薄膜。自調式刮刀膜厚預測模型由固定式刮刀塗佈理論出發,透過Navier-Stokes Eq.與Continuity Eq.加上適當假設,求得最終膜厚預估,再利用力矩平衡與不可壓縮流體積不變原則,得到膜厚預測模型的統御方程式,計算過後與實驗結果做定性的比較,得到膜厚趨勢一致。最終,製作大面積照明元件遇到雙層塗佈與ITO膨脹問題,在探討排除原因後,以雙層塗佈電洞傳輸層(PEDOT:PSS)以及發光層(Poly[9,9-dioctylfluorenyl-2,7-diyl]-End capped with N,N-Bis(4-methylphenyl)-aniline),製作無細條紋與暗塊的照明元件。
    In this thesis, we discuss the problems such as dark fine stripe, large-scale dark block and uneven evaporation of the wet film, which were observed by large-scale PLED lighting of Yo Han Wu. These issues were discussed and I propose the effective approaches to improve the equipment. And then I build the film thickness prediction model of the self-adjusting blade coating as a trend indicator to adjust the thickness parameters. After the exclusion of double coating and ITO expansion problems, I made a lighting device without the problems of dark fine stripe and large-scale dark blocks.
