Abstract

一種抗反射光學玻璃之製法，係於一載體上設有多數鑽石切割線， 令該等鑽石切割線於光學玻璃之表面上離心、彈性地甩抛、研磨成具有蛾眼結構(moth-eye structure)之溝槽，俾降低光反射且增加光穿透量者。本發明亦包括藉該製法所製成之光學玻璃產品者。

Description

抗反射光學玻璃之製法及其製品
本發明係關於一種抗反射光學玻璃之製法及其製品。
習知顯示器螢幕等光學玻璃為降低光反射，並增加光穿透量，有於其面上藉微影蝕割(photolithography)以形成具蛾眼結構(moth-eye structure)之抗反射表面。
唯藉微影蝕刻以形成蛾眼結構表面之光學玻璃仍具有以下之缺點：
1.製作成本極高，良率低，不具經濟效益。
2.因使用蝕刻液，腐蝕性高，污染性高，不利環境保護。
3.製程限制多，例如只適合製作尺寸較小者，且須為平直玻璃不能有曲面者，如是遂限制相關光學玻璃產品之開發、量產製造。
本案發明人有鑒於此，乃加研究創新，揭示出本發明新穎之抗反射光學玻璃之製法及其製品。
本發明之目的旨在提供一種抗反射光學玻璃之製法，係於一載體上設有多數鑽石切割線，令該等鑽石切割線於光學玻璃之表面上離心、彈性地甩抛、研磨成具有蛾眼結構(moth-eye structure)之溝槽，俾降低光反射且增加光穿透量者。本發明之另一目的包括藉該製法所製成之光學 玻璃產品者。

圖2係依本發明研磨工具及待研磨基板之立體示意圖。
圖3係本發明製作時相關工具及基板之橫剖示圖。
圖4係本發明以多方向研磨、刻畫使溝槽交織成蛾眼結構之示意圖。
圖5為圖4之刻畫結果頂視示意圖。
圖6為自圖5之圈示註記區域之放大斜視圖。
圖7為本發明另一可取實體示意圖。
參閱圖1~圖6，本發明製法主要係令一研磨裝置在光學玻璃上進行研磨、刻畫，以製成具有蛾眼結構之光學玻璃者。
該研磨裝置(尤如圖1，2所示者)實係包括：一載體(1)包括轉輪者，以及至少一條或多數鑽石切割線(2，Diamond Cutting Wire)設於該載體(上)以構成該研磨裝置者。各該鑽石切割線(2)呈圈狀(loop)等形狀繫於該載體(1)上。
該載體(1)為轉輪時可以馬達驅轉其轉軸(11)藉以轉動，令設於輪面(12)上之該等鑽石切割線(2)所固連之多數鑽石顆粒(21)在光學玻璃基板(3)上進行研磨、刻畫者。
各該鑽石切割線(2)上以多數鑽石顆粒(21，diamond grains or beads)鍍著、鍵結、連結、或設置於該鑽石切割線(2)上。
尤如圖3所示者，啟動載體(1)之轉動，調整載體(1)軸心與基板(3)之間距或高度(H)，以輸送帶等方式推進基板(3)呈F方向前進，此時旋轉載體(1)亦即轉輪，使其上之鑽石切割線(2)諸鑽石顆粒(21)離心、彈性地甩抛、研磨於該基板(3)面上，以形成溝槽，例如可刻畫出深度為奈米等級之溝槽者。
各鑽石顆粒(21)上之尖銳角或稜角在基板上甩抛畫過時，由於鑽石之高硬度並配合切割線旋轉之離心力及彈性力所致，僅需輕微之作用力即可將基板(3)表面研磨、刻畫成極細微之溝槽。
該基板(3)可為手機面板、觸控螢幕(包括ATM者)、顯示器表面、鏡頭表面、以及其他光學玻璃表面。
該光學玻璃，除玻璃外，亦包括透明塑膠，如聚碳酸酯(polycarbonate,PC)等等。
各該鑽石切割線(2)亦可如圖7所示者，直接繫於載體(1)之輪面(12)上，該輪面(12)可製自彈性體(elastomer)，如是乃構成本發明之另一可取實體。
本發明之操作可操控載體(1)轉速以控制鑽石切割線(2)之「甩勁」(甩抛之力道)，並控制刻痕之密度，以相應配合微結構之尺寸，與增透光之波長，且可調整載體轉輪與基板間之間距(H)，使鑽石切割線能旋轉、離心、彈性地壓甩於基板表面，仿如令鑽石切割線動態地「服貼」於基板表面上進行研磨刻畫，使刻痕均勻，且尤適用於曲面上，以有效遂行 溝槽之刻畫操作。
經刻畫所成之蛾眼結構，在光學玻璃表面上形成抗反射面，可大降入射光之反射，亦能增加光之穿透量，避免或減少刺眼之眩光(glare)，提升光學玻璃之效能。
如圖4~6所示者，載體(1)轉軸(11)先與基板(3)之縱軸(X)正交(如A處)，旋轉載體(1)使其上之鑽石切割線(2)在基板(3)上研磨、刻畫成與縱軸(X)平行之第一溝槽(31)；令基板(3)沿F方向挺進，在B處，此時載體(1)轉軸(11)與縱軸(X)交成135度，旋轉載體(1)使鑽石切割線(2)在基板(3)上研磨、刻畫成與縱軸(X)及第一溝槽(31)交成45度之第二溝槽(32)；持續地令基板(3)向前之方向(F)挺進，在C處，此時載體(1)與縱軸(X)交成45度，旋轉下，鑽石切割線(2)在基板(3)上刻畫出與第一溝槽(31)交成135度之第三溝槽(33)如C，第一、二、三溝槽(31，32，33)相互交錯，遂切割成如圖6所示之蛾眼結構(34)。(註：A，B，C為溝槽顯示區)
本發明可調控相關之製程或操作參數，以調變產品尺寸、特性並能對應不同波長光，而可調控光之增透量。
本發明較諸習知技術具有以下之優點：
1.整個製程及設備構造簡單、製作成本大降，適於大量製造，極富產業經濟價值。
2.鑽石切割線上之鑽石顆粒不會滾動，使研磨、刻痕效果易於控制，有助於品質穩定與良率之提昇。
3.由於藉助鑽石切割線之彈性、離心之甩抛研磨，使刻痕均勻，尤適於曲面之加工製作。
4.不必使用習知製法之腐蝕性蝕刻液，對環保裨益尤多。
5.適用於大尺寸光學玻璃之製作，可量產，產能大。
6.由於製程參數易於調整，故可對應不同波長之光而調控光之增透量，便於因應各種光學玻璃不同光學特性之需求。
本發明可於不違本發明之精神及範疇下，作適當之修飾與改變，而不加以限制
前述研磨、刻畫之方向係可加調整、變化，而未予限制者。
