    • 積層製造具有巨大潛力製造傳統加工技術無法輕易達成的複雜結構。最近，許多公司開發基於液晶顯示的高性價比3D列印系統。然而，列印物的解析度和均勻度對於微光學元件和微流控晶片等精密應用來說還不夠。在本文中，我們提出兩種光學結構來增強405nm LED背光模組的準直性和均勻性。此結構被命名為準直膜（Collimation Film，CF），此膜片的設計是基於柱狀透鏡陣列。第一種準直膜稱為單面結構準直膜(Single-Sided Structure Collimation Film，SSSCF)，是由柱狀透鏡陣列、針孔和高反射鍍膜所組成。柱狀透鏡陣列搭配針孔可將發散的入射光的角度收斂成準直光出射。準直膜的高反射率鍍膜可以將沒有進入針孔的光再次反射回背光模組中進行能量再循環。單面結構準直膜的透射特性是半峰全寬為±3.4°的準直光。第二種準直膜稱為雙面結構準直膜(Double-Sided Structure Collimation Film，DSSCF)，由柱狀透鏡陣列、梯形微結構、針孔和反射鍍膜組成。與單面結構準直膜相比，雙面結構準直膜有梯形微結構，此梯形微結構可以反射來自背光的大角度的光成小角度的光出射。因為梯形微結構的存在，雙面結構準直膜不會形成大角度的漏光。最後，我們成功地開發了一種具有低吸收特性的直下式準直背光模組，具有良好的能量增益(Gain=5.6)、均勻性(Uniformity=81.4%)和準直面光源特性(FWHM<±5.5°)。本研究開發的準直背光模組未來有大的應用潛力，包括需要高精細度的3D列印機、高對比或窄視角的液晶顯示器、及用於精密機器視覺系統中的遠心照明裝置等。

    Additive manufacturing has great potential to fabricate complex structures that tradi-tional machining techniques can’t easily achieve. Recently, cost-effective 3D printing systems based on liquid crystal display (LCD) have been developed by many companies. However, the resolution and uniformity of the printing objects are not good enough for del-icate applications, such as micro-optics devices and microfluidic chips. In this article, we proposed two kinds of novel optical structures to enhance the collimation and uniformity property of the 405nm light-emitting diode (LED) backlight. The structured film is named a collimation film (CF), the design of which is based on lenticular lens arrays. The first kind of CF is called single-sided structure collimation film (SSSCF), which is composed of lenticular lens arrays, apertures, and reflective coating. Lenticular lens arrays accompa-nied by the apertures transform the diverse incoming light into collimation outgoing light. The reflection coating of CF can reflect light that does not enter the aperture to the back-light module again for energy recycling. The transmission property of the SSSCF is a col-limated light, which is ±3.4° full width at half maximum (FWHM) of beam divergence an-gle. The second kind of CF is called double-sided structure collimation film (DSSCF), which is composed of lenticular lens arrays, trapezoidal microstructure, apertures, and re-flective coating. Compared with SSSCF, DSSCF has trapezoidal microstructures that can reflect the light of large angles coming from the backlight to the light of small angles. Because of the trapezoidal microstructures, there is no large angle leakage light from DSSCF. Finally, we successfully developed a high efficiency direct-lit collimated back-light module, which presents high energy gain (Gain=5.6), good uniformity (Uniformi-ty=81.4%), and good collimation properties (FWHM<±5.5°). The collimation backlight module has great application potential, such as high precision 3D printer, high contrast or narrow viewing angle LCD, and telecentric illumination device for high accuracy machine vision system.
