    Abstract: 本論文主要研究可區域化2D/3D切換顯示柱狀透鏡技術重要元件凹形微透鏡膜,採用卷對卷技術與田口方法實驗設計相結合制定直交表計劃的實驗組,各實驗組藉由成形機進行微結構滾壓固化成形後,進行成品量測幾何形狀尺寸,得到實驗數據進行評估分析,品質指標為2D/3D切換影像顯示效果和面板對位貼合是否有錯位,要達到品質指標尺寸精度要準確,所以選用望目品質特性分析4組關鍵尺寸精度希望符合或趨近規格值。
    實驗共分為兩階段,第一階段實驗選定4組控制因子和3水準,A因子為成形速度、B因子為紫外光功率、C因子為收/放卷張力、D因子前/後壓輪壓力,不考慮交互作用選用L9直交表規劃實驗組,執行實驗得到製程參數最佳組合(A3、B2、C1、D1)以及因子影響程度大小依序為D因子、B因子、C因子、A因子。第二階段再確認實驗規畫製程參數原始組合(A2、B2、C2、D2)和最佳組合(A3、B2、C1、D1)實驗組,執行實驗得到實驗值之後,進行SNR預測值與實驗值驗證,分析後得到的結果SNR實驗值是夠準確。
    研究結果為凹形微透鏡膜4組關鍵尺寸製程參數最佳組合比原始組合提升尺寸平均值為凹形高度共提升0.04μm、凹形間距共提升0.02μm、凹形曲率半徑共提升0.5 μm、凹形微透鏡膜厚度共提升0.5μm。4組關鍵尺寸製程參數最佳組合比原始組合的尺寸平均值更接近規格值,符合望目品質特性趨近目標值。
    ;This study investigated concave micro lens films, a key component in localized 2D/3D switchable display lenticular lens technology, using the Roll-to-Roll technology in conjunction with a Taguchi Method experimental design to develop orthogonal table-planned experiment groups. Each group was subjected to forming machine for rolling and solidifying of microstructures. Geometric shapes of end products were measured and experimental data were evaluated and analyzed. Quality indicators were 2D/3D switchable display performance and the para bonding disposition of the panel. To satisfy the quality indicators, the size of the end products must be highly accurate. Thus, the nominal-the-best (NTB) quality characteristic was adopted to measure the accuracy of four critical sizes in order to gain results that were consistent or close to specifications.
    Experiments were divided into two stages. In the first stage, four sets of control factors and three standards were selected. Factor A was formation speed, factor B was UV power, factor C was winding/rewinding tension, and factor D was front/rear roller pressure. Interaction among the factors was not considered. The L9 orthogonal table-planned experiment groups were analyzed to obtain the ideal process parameter combination (A3, B2, C1, D1) and the descending order of factor influence (D, B, C, A). In the second stage, the original process parameter combination (A2, B2, C2, D2) was compared with the ideal process parameter combination (A3, B2, C1, D1). The obtained experimental values used to verify the SNR prediction were highly accurate.
    Findings indicated that the ideal process parameter combination of the four critical sizes was increased compared with the original process combination. On average, the concave height increased by 0.04 μm, the concave interval increased by 0.02 μm, the concave radius curvature increased by 0.5 μm, and the concave thickness increased by 0.5 μm. Moreover, the four critical sizes produced by the ideal process parameter combination achieved better consistency with specifications relative to the original process combination. Thus, the ideal combination satisfied the NTB quality characteristic and approximated the target values.
