技術簡介

以高穿透率之單體、光起始劑及墨水與基板Primer表面能差之選擇與調控作為設計μ-3D形體微透鏡UV墨水配方之依據。透過墨水配方組成調控墨水物性，使墨水具備良好的噴墨適性，並提升墨滴噴墨墨速，並經由對primer及微透鏡UV墨水之表面張力差精準調控微透鏡形體調控於高(h)/直徑(D)比為1/4.3-1/5.5。，應用於LCD導光板噴印微透鏡之UV油墨。

Abstract

we have successfully developed self-madeμlens UV inkjet ink and its corresponding primer for LCD light wave plate. To achieve a well-defined micro-lens array on primer-precoated substrate via inkjet-printing process and UV curing, the physical properties ofμlens UV ink were carefully adjusted to obtain good ink jetting stability and optimal velocity, so that multi-drops can merge into one isolated drop, the ratio of height to diameter of micro-lens reaches 1/4.3-1/ 5.5..

最後本計畫成功研製出一組primer及微透鏡UV噴印墨水，完成μ-3D功能形體之微透鏡噴印其h/D = 1/3.4-1/5.9，硬度H，附著度5級，光之穿透度99%（400~700 nm）耐IPA溶劑擦拭100次。本計畫成功的建立:（1）設計噴印數位墨水配方組成及配製墨水技術，係透過調整primer及微透鏡墨水表面張力差，使噴印微透鏡墨水噴印在PMMA導光板上形成微透鏡。以共軛焦顯微鏡量測可得該微透鏡之高度為10.38μm、直徑為57.09μm 以及高(h)/直徑(D)比為1/4.3-1/5.5。（2）調控墨水噴墨適性及墨滴噴墨速度，墨水噴墨速達4.8 m/s之精準定位噴印技術。(3) 開發μ-Lens功能形體噴印技術及噴印42吋μ-Lenses平面顯示器PMMA導光板。

Technical Specification

By printing self-made μlens UV ink on primer/PMMA substrate and UV curing, the height and diameter of micro-lens measured by a confocal microscopy are 10.38μm and 57.09μm, respectively, i.e., the ratio of height to diameter of micro-lens reaches around 5.5. Moreover, the inkjet-printed micro-lens possesses IPA resistance (wiping by 100 times), adhesion of five class (3M 600 tape test), pencil hardness H, and the optical transmittance can reach up to 99% in the visible wavelength (400 to 700nm). Therefore, we have developed some remarkable techniques during the project：(1) design and formulation ofμlens UV jetting inks, (2) accurate merging technique of ink drops with a high height/diameter ratio when jetting velocity reaches 4.8 m/s, (3) development of inkjet-printed μlens array on 42”PMMA light guide plate.
