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.
