摘要: 本論文主要利用Microfab壓電式噴墨系統噴印UV 固化膠於光學級 PC及玻璃基板 (substrate) 上。利用噴印技術及膠體表面張力 (surface tension) 的物理特性來製作微透鏡陣列並應用於導光板微結構,達到抑制全反射,增加正向出光效率及均齊度。透過控製噴印液滴數、基板溫度及 UV 硬化膠黏度(10cp及20cp)可改變透鏡粒徑大小及成型厚度。以噴嘴 (nozzle) 50um噴印微透鏡,最小粒徑小於95um。此技術應用於導光板上可依需求噴印不同粒徑、厚度及間距之微透鏡陣列 (micro lens array) 以達導光板所需之最佳效果。實驗中噴印UV 固化膠微透鏡導光板樣品所得之最佳正面出光效率比較於未噴印前增加75%,實驗結果證明正面出光效率與微透鏡粒徑、厚度及填充率(fill factor)成正比。依近光源處微透鏡填充率較低作區塊劃分噴印微透鏡結構於導光板上其均齊度可達82%以上。
This paper mainly uses a Microfab-Inkjet piezoelectric ink-jet system to print UV adhesives on optical-grade PC and glass substrates. The physical characteristics of ink-jet technology and adhesive surface tension were used to manufacture micro lens arrays and applied to the microstructure of light-guide plates to achieve attenuated total reflection (ATR) inhibition and increase the positive light efficiency and uniformity. Through controlling the ink-jet liquid drop amount, the substrate temperature, and the UV adhesive viscosity (10cp and 20cp), the lens particle diameter size and formation height can be changed. The micro lens is printed with a 50um nozzle and a minimum diameter less than 95um. This technology is applied to light-guide plates and can achieve optimal effects by ink-jet printing micro lens arrays with different particle diameters, height, and spacing as demanded. The optimal positive light efficiency obtained by the experiment ink-jet UV adhesive micro lens light-guide plate sample was 75% greater than before ink-jet printing. The experiment results prove that there is a positive correlation between positive light efficiency and micro lens particle diameter, height, and fill factor. The uniformity of ink-jet micro lens structures on light-guide plates can reach over 82% with area divisions based on the lower fill-rate of the micro lenses near the light source.
