201132501 六、發明說明: 【發明所屬之技術領域】 本發明係關於一種光學膜貼合裝置及貼合方法,以及 使用該貼合方法之光學顯示裝置的製造方法。 【先前技術】 近來,液晶顯示裝置被使用於各式各樣的機器上。一 般而言,前述液晶顯示裝置的製造包含有貼合各種光學膜 至液晶顯示基板上的步驟。 舉例而言,已知一種如前述光學膜的貼合方法,其包 含:切斷步驟,在偏光板上介設著黏著劑層而貼附有剝離 膜的帶狀薄膜,當垂直其長邊方向之進行方向侧的切斷面 向基板之相對應長度前進時,將該帶狀薄膜沿垂直其長邊 方向之方向留下該剝離膜而至少將該偏光板和該黏著劑層 切斷;分離步驟,從該切斷步驟切割出的: 膜分離:以及貼合步驟,把已將該剝離膜分離後之該= 片的黏著面貼合至該基板之對應位置,並使得該薄膜片之 切斷面與基板行進方向側端面平行(例如參考專獻 又,已知一種方法,其包含:第一切斷貼合步驟,使 =有對應光學顯示單元短邊寬度之第1學膜之薄片帶 狀製品所捲曲而成的卷筒,對應於光學顯示單元 度將其切斷之後,將第—絲顧合至光學顯*單元的一 二表以及第二切斷貼合步驟,使用具有對應光學顯示 早疋長邊i度之第二光學膜之薄片帶狀製品所捲曲而成的 201132501 卷筒,對應於光學顯示單元短邊的長度將其切斷之後,將 第二光學膜貼合至光學顯示單元的另一側表面(例如參考 專利文獻2)。 如前述,一般而言,習知方法係使用已預先裁剪成寬 度接近欲貼合之基板等寬度的料卷卷筒,來進行貼合光學 膜的步驟。 專利文獻1 :日本專利公告「專利第4346971號( 2009 年10月21日發行)」。 專利文獻2 :曰本專利公告「專利第4307510號( 2009 年8月5日發行)」。 但是,仍強烈需要能以比專利文獻1、2所記載之方法 更高生產效率來貼合光學膜。 有鑑於前述問題點,本發明之目的係實現能以更高效 率貼合光學膜的光學膜貼合裝置及貼合方法。 【發明内容】 本發明之光學膜貼合裝置及貼合方法係可適用於需貼 合光學膜之液晶顯示基板等的各種基板上。 為了解決該問題,本發明人積極地針對能以更高效率 來貼合光學膜的方法進行研究。其結果得知,不使用已預 先裁剪成欲貼合基板等之寬度的料卷卷筒,而是在將光學 膜貼合至基板時將其裁剪成特定寬度,便可省下預先裁剪 成欲貼合基板等之寬度的步驟,其結果係能減少生產步驟。 此外,使用具有基板相對應寬度之2倍以上寬度的帶 201132501 狀光學膜料卷,藉由將配合基板寬度裁剪後所剩餘之帶狀 光學膜料卷部分進行捲曲,當帶狀光學膜料卷之長度變得 較貼合至基板所需長度更短的情況下,只要使用已捲曲好 之帶狀光學膜料卷的剩餘部分來進行貼合,就可減少光學 膜料卷的更換次數,其結果,能縮短貼合步驟的中斷時間, 進而完成本發明。 即,為解決上述問題,本發明之光學膜貼合裝置係使 用捲曲呈卷筒狀之帶狀光學膜料卷來將光學膜連續地貼合 至基板,其中,該帶狀光學膜料卷之寬度係該基板之相對 應寬度的2倍以上,並具備有:捲出單元,係將該帶狀光 學膜料卷沿其長邊方向捲出;切斷單元,係沿其長邊方向 將捲出後之該帶狀光學膜料卷切斷,切成具有對應該基板 寬度的第一帶狀光學膜、以及具有該剩餘寬度的帶狀光學 膜;貼合單元,係將該第一帶狀光學膜貼合至該基板;以 及捲曲單元,係捲曲具有剩餘寬度的帶狀光學膜。 根據該結構,由於具備有該切斷單元,即使光學膜料 卷之寬度沒有預先裁剪成基板之相對應寬度,亦可將光學 膜連續地貼合至基板。因此,可省略預先將光學膜料卷之 寬度裁剪成基板之相對應寬度的步驟,而能高效率地將光 學膜貼合至基板。又,由於省略了步驟數量,可降低因於 步驟之間搬運而引起的異物咬入或黏附等外來缺陷。 此外,根據該結構,將第一光學膜貼合至基板的同時, 藉由捲曲單元來將具有剩餘寬度之帶狀光學膜進行捲曲。 因此,在第一帶狀光學膜之長度變得較貼合至基板所需長 201132501 度更短的情況下,只要將該捲曲好之帶狀光學膜與第一光 學膜相連接,則無需更換全新的光學膜料卷,即可立即再 繼續進行貼合。即,可減少光學膜料卷的更換次數。 因此,根據該結構,可達到提供一種以更高效率貼合 光學膜之光學膜貼合裝置的效果。 本發明之光學膜貼合裝置中,如前述般,係使用捲曲 呈卷筒狀之帶狀光學膜料卷來將光學膜連續地貼合至基 板,其中,該帶狀光學膜料卷之寬度係該基板之相對應寬 度的2倍以上,並具備有:捲出單元,係將該帶狀光學膜 料卷沿其長邊方向捲出;切斷單元,係沿其長邊方向將捲 出後之該帶狀光學膜料卷切斷,切成具有對應該基板寬度 的第一帶狀光學膜、以及具有該剩餘寬度的帶狀光學膜; 貼合單元,係將該第一帶狀光學膜貼合至該基板;以及捲 曲單元,係捲曲具有剩餘寬度的帶狀光學膜。 因此,可達成提供一種能以更高的效率貼合光學膜之 光學膜貼合裝置的效果。 又,本發明之光學膜貼合方法中,如前述般,係使用 捲曲呈卷筒狀之帶狀光學膜料卷來將光學膜連續地貼合至 基板,其中,該帶狀光學膜料卷之寬度係該基板之相對應 寬度的2倍以上,並反覆地進行包含後述之一連串步驟: 捲出步驟,係將該帶狀光學膜料卷沿其長邊方向捲出;切 斷步驟,係沿其長邊方向將捲出後之該帶狀光學膜料卷切 斷,切成具有對應該基板寬度的第一帶狀光學膜、以及具 有該剩餘寬度的帶狀光學膜;貼合步驟,係將該第一帶狀 201132501 至該基板;以及捲曲步驟’係捲曲具有剩餘寬 度的帶狀光學膜。 因此,可達成以更高效率貼合光學膜的效果。 刖 此外,本發明之光學顯示裝置製造方法中,包含藉由 述之本發明光學合方法而將光學膜連續地貼合^基 板上的步驟。 因此,可達成以更高效率製造光學膜的效果。 本發明之其它目的、特徵及優點,可經由以下所示的 錢而充份明瞭。X,本發明之優點可透過參相之附加 圖式與以下說明而明瞭。 【實施方式】 以下說明本發明之一實施形態。 [I ]光學膜之貼合方法 (第一實施形態) 關於本發明之第一實施形態’以下使用帛1目至第6 圖進行詳細說明。 第1圖係顯示本實施形態之光學膜貼合裝置一例的概 略構造示意圖之前視圖。 ,如第1圖所不,本實施形態之光學膜貼合裝置係使用 捲曲呈卷筒狀之帶狀光學膜料卷】來將光學膜連續地貼合 =基板10的光學膜貼合裝置。另外,在第〗圖中,帶狀光 予膜料卷1等的帶狀光學膜之表面標示為元件符號「2」, 内面則標示為元件符號「3」。 201132501 該帶狀光學膜料卷1之寬度係基板10之相對應寬度的 2倍,並具備有:搬送滾筒6 (捲出單元),係將該帶狀光 學膜料卷1沿其長邊方向捲出;切斷單元8,係沿其長邊方 向將捲出後之該帶狀光學膜料卷1切斷,切成具有對應該 基板10寬度的第一帶狀光學膜4、以及第二帶狀光學膜5 (具有該剩餘寬度的帶狀光學膜);貼合滾筒11 (貼合單 元),係將該第一帶狀光學膜4貼合至該基板10;以及搬送 滾筒7 (捲曲單元),係捲曲具有剩餘寬度的帶狀光學膜。 又,本實施形態之光學膜貼合方法,可使用捲曲呈卷 筒狀之帶狀光學膜料卷1來將光學膜連續地貼合至基板 10,其中,該帶狀光學膜料卷1之寬度係該基板10之相對 應寬度的2倍,並反覆地進行包含後述之一連串步驟:捲 出步驟,係將該帶狀光學膜料卷1沿其長邊方向捲出;切 斷步驟,係沿其長邊方向將捲出後之該帶狀光學膜料卷1 切斷,切成具有對應該基板10寬度的第一帶狀光學膜4、 以及第二帶狀光學膜5 (具有該剩餘寬度的帶狀光學膜); 貼合步驟,係將該第一帶狀光學膜4貼合至該基板10 ;以 及捲曲步驟,係捲曲第二帶狀光學膜5。 以下,可舉出使用了前述光學膜貼合裝置的範例,據 以說明本實施形態之光學膜貼合方法。 (a)帶狀光學膜料卷 帶狀光學膜料卷1可以是僅由光學膜所構成者,亦可 為層積有其它層之結構。該光學膜可例舉有偏光膜、相位 差膜等,亦可為該等兩種以上所組合而成的複合膜。 201132501 另外,在本實施形態中,將說明使用了在光學膜上依 序層積有黏著劑層、剝離膜的範例。 舉例而言,在32吋顯示裝置用基板上貼合光學膜的情 況,帶狀光學膜料卷1之寬度可使用1200〜1400mm者。 在該情況中,前段用為三次份量,而後段用為兩次份量。 (b) 基板 基板10可例舉有用於液晶顯示基板、電漿顯示基板、 有機EL基板、TFT基板、印刷基板等的玻璃基板及合成樹 脂基板等’亦可用於預先形成有電池單元(Cell)、電極等之 組件的基板。 (c) 捲出步驟 捲出步驟係將該帶狀光學膜料卷丨沿其長邊方向捲出 的步驟。在本實施形態中,如第1圖所示,作為捲出單元 係藉由自帶狀光學膜料卷1之雙面側夾持的搬送滾筒6來 搬送帶狀光學膜料卷1。 (d) 切斷步驟 一切斷步驟係沿其長邊方向將捲出後之該帶狀光學膜料 卷1切斷,切成具有對應該基板10寬度的第一帶狀光學膜 4、以及具有該剩餘寬度之帶狀光學膜的步驟。 在本實施形態中,帶狀光學膜料卷!之寬度為該基板 10之相對應寬度的2倍。因此’在該切斷步驟中,藉由切 斷單元8沿其長邊方向將捲出後之該帶狀光學關^ i切 成兩份,城具有基板1G之相對應寬度的第—帶狀光學膜 4和第二帶狀光學膜5。 201132501 該切斷單元8可例舉有各種刀刃或雷射切割裝置。 (e )貼合步驟 貼合步驟係將該第一帶狀光學膜4貼合至該基板10的 步驟。 在本實施形態中,帶狀光學膜料卷1可使用在光學膜 上依序層積有黏著劑層、剝離膜12之結構。因此,在本實 施形態中,進行貼合之前,留下剝離膜12而將該第一帶狀 光學膜4處之光學膜及黏著劑層切割成該基板10之貼合領 域的相對應長度。接著,其後使該剝離膜12自第一帶狀光 學膜4處分離,並藉由貼合滾筒11把已將剝離膜12剝離 後之第一帶狀光學膜處的黏著劑層貼合至基板10處之貼合 區域,藉以將光學膜貼合至基板10。 作為將第一帶狀光學膜4處之光學膜及黏著劑層切斷 的該切斷單元(圖中未顯示),舉例而言,可例舉出藉由湯 姆森刀模(Thomson blade)以油壓式或馬達驅動曲柄之切紙 機式(guillotine)切斷器、雷射切割裝置、圓形滾刀、圓形切 削刃之拉斷式切斷器等習知使用的結構。 (f)捲曲步驟 捲曲步驟係自帶狀光學膜料卷1將具有已把第一帶狀 光學膜4切斷後所剩餘寬度之帶狀光學膜的步驟。在本實 施形態中,帶狀光學膜料卷1之寬度係該基板10之相對應 寬度的2倍。因此,在本實施形態之捲曲步驟會捲曲具有 基板10之相對應寬度的第二帶狀光學膜5。在本實施形態 中,捲曲單元係使用自第二帶狀光學膜5之雙面側夾持的 201132501 搬送滾筒7,藉以搬送第二帶狀光學膜,並將其捲曲至捲芯 處的結構。 如前述般,本實施形態之方法係包含了該切斷步驟及 捲曲步驟,即使不預先將光學膜料卷寬度裁剪成基板之相 對應寬度,亦可將光學膜連續地貼合至基板。因此,可省 略預先將光學膜料卷寬度裁剪成基板之相對應寬度的步 驟’故成高效率地將光學膜貼合至基板。 (g)膜連接步驟 在本實施形態中,較佳地,在當第一帶狀光學臈4之 長度變得較貼合至基板10之所需長度更短之後,可進行連 接第一帶狀光學膜4與第二帶狀光學膜5的連接步驟。 在本實施形態中,僅管臈連接步驟係經由膜連接單元 所進行,但其亦可使用手動作業來進行。另外,舉例而言, 本實施形態之膜連接單元可例舉有藉由電腦控制來自動進 行後述各步驟的結構。 關於本實施形態之膜連接步驟,將使用第2圖來進行 說明。第2圖係顯不膜連接步驟中光學膜貼合裝置的概略 構造示意圖之前視圖。 在本實施形態中,如第2a圖所示,在第一帶狀光學膜 4之長度變得較貼合至基板10所需長度更短的情況下,便 藉由切斷單元15,先將第二帶狀光學膜5自帶狀光學膜料 卷1切斷分離。 此處,捲曲好之第二帶狀光學膜5的捲出方向與帶狀 光#膜料卷1的捲出方向呈相反方向(即,表面和内面相 201132501 反)。因此,如第2b圖所示,反轉第二帶狀光學膜5 (在本 實施形態中,係以捲出方向作為迴轉軸迴轉180°),使得捲 曲好之第二帶狀光學膜5的卷出方向與帶狀光學膜料卷1 的卷出方向呈相同方向。 其後,如第2c圖所示,將反轉後之第二帶狀光學膜5 與帶狀光學膜料卷1進行膜連接。接著,如第2d圖所示, 藉由切斷單元15將帶狀光學膜料卷1從已膜連接完成的帶 狀光學膜處切斷分離。 (h) 第二捲出步驟 在本實施形態中,於膜連接步驟完成之後,則進行將 連接好之該帶狀光學膜朝貼合滾筒11捲出的第二捲出步 驟。在本實施形態中,如第3圖所示,藉由讓原先作為捲 曲單元之搬送滾筒7的迴轉方向反向迴轉,即可作為第二 捲出單元。 如此一來,可在第二捲出步驟之後,使用該連接好之 帶狀光學膜,同樣地進行前述貼合步驟。因此,在本實施 形態之方法中,即使帶狀光學膜料卷1之長度變短時,亦 可藉由第二帶狀光學膜5立即再繼續進行貼合。 (i) 帶狀光學膜料卷之更換步驟 較佳地,在本實施形態中,將第一帶狀光學膜4和第 二帶狀光學膜5連接好之後,在當第二帶狀光學膜5之長 度變得較貼合至基板10所需長度更短之前,便將使用完畢 之帶狀光學膜料卷1更換成捲曲成卷筒狀之全新帶狀光學 膜料卷Γ (參考第4圖)。 12 201132501 據此,在第二帶狀光學膜5之長度變得較貼合至基板 10所需長度更短的情況下,即可使用全新帶狀光學膜料卷 r來立即進行膜連接步驟,其結果,可立即再繼續進行貼合 步驟。 (j)料卷連接步驟 車乂佳地,在本實施形態中,當第二帶狀光學膜5之長 度變得較貼合至基板10所需長度更短之後,更包含有:料 卷連接步驟,係將第二帶狀光學膜5與更換後之全新帶狀 光學膜料卷Γ相連接。 在本實施形態中,料卷連接步驟可與膜連接步驟同樣 地藉由前述之膜連接單元所進行,但亦可藉由手動作業來 進行。另外,舉例而言,本實施形態之膜連接單元可例舉 有藉由電腦控制,自動進行前述膜連接步驟與後述各步驟 的結構。 使用第4圖來說明本實施形態之料卷連接步驟。第4 圖係顯示在料卷連接步驟中,光學膜貼合裝置的概略構造 示意圖之前視圖。 在本實施形態中,如第4a圖所示,在第二帶狀光學膜 5之長度變得較貼合至基板10所需長度更短的情況下,經 由搬送滾筒6’將全新帶狀光學膜料卷1,朝第二帶狀光學膜 5捲出。 ' 其-欠,如第4b圖所示,將全新帶狀光學膜料卷丨,連接 士第-帶狀光學膜5處。接著,如第4c圖所示,藉由切斷 〇D 6攸已連接好帶狀光學膜處將第二帶狀光學膜5切 201132501 斷分離。 藉此,如第4d圖所示,與前述方法相同地,可使用帶 狀光學膜料卷Γ來進行捲出步驟、切斷步驟、貼合步驟以 及捲曲步驟。 如前述般,本實施形態之光學膜貼合方法可藉由反覆 進行前述一連串步驟,來將光學膜連續地貼合至基板10。 以下,使用第5圖和第6圖來更具體說明。 第5圖係顯示本實施形態之光學膜貼合方法一例的流 程圖。又,第6圖係顯示在第5圖所示流程圖之各步驟中, 光學膜貼合裝置示意圖之俯視圖。 如第5圖所示,本實施形態之光學膜貼合方法係反覆 進行後述步驟:以全新料卷(帶狀光學膜料卷1 )進行一般 作業方式(步驟1);進行捲曲料卷(第二帶狀光學膜5) 之膜連接(步驟2);以捲曲料卷(第二帶狀光學膜5)進 行一般作業方式(步驟3);進行全新料卷(帶狀光學膜料 卷Γ)之膜連接(步驟4)。 又,如第6圖所示,步驟1係將帶狀光學膜料卷1切 成第一帶狀光學膜4與第二帶狀光學膜5,且使用第一帶狀 光學膜4來進行貼合步驟。執行步驟1直到第一帶狀光學 膜4之長度變得較貼合至基板10所需長度更短為止。 接著,在步驟2中,反轉第二帶狀光學膜5,使其朝向 位在第一帶狀光學膜4搬送方向上的預備滾芯20處移動之 後,將第二帶狀光學膜5連接至第一帶狀光學膜4。 其後,在步驟3中,使用第二帶狀光學膜5來進行貼 14 201132501 合步驟。執行步驟3直到第二帶狀光學膜5之長度變得較 貼合至基板10所需長度更短為止。於此期間内,將帶狀光 學膜料卷1更換成全新帶狀光學膜料卷Γ。接著,在步驟4 中,將全新帶狀光學膜料卷Γ連接至第二帶狀光學膜5。 如此一來,藉由反覆地進行前述步驟1至步驟4,便可 將光學膜連續地貼合至基板10。 (第二實施形態) 以下使用第7圖至第9圖來詳細說明本發明之第二實 施形態。但是,與前述第一實施形態所使用者為相同組件 時,則賦予相同之元件符號並省略說明。 在本實施形態中,除了帶狀光學膜料卷1之寬度為基 板10之相對應寬度的3倍之外,其它結構幾乎皆與第一實 施形態相同。 第7圖係顯示本實施形態之光學膜貼合裝置另一例的 概略構造示意圖之前視圖。 如第7圖所示,在本實施形態之光學膜貼合裝置中, 與第1圖所示結構不同的是,帶狀光學膜料卷1之寬度為 基板10之相對應寬度的3倍。因此,藉由切斷單元8沿其 長邊方向將捲出後之該帶狀光學膜料卷1切斷,會切成具 有對應該基板10寬度的第一帶狀光學膜4、第二帶狀光學 膜5、以及第三帶狀光學膜18。接著,各自藉由搬送滾筒7、 7'來捲曲第二帶狀光學膜5和第三帶狀光學膜18。 接著,在該第一帶狀光學膜4之長度變得較貼合至基 板10所需長度更短的情況下,與前述第一實施形態相同 15 201132501 地,藉由膜連接單元連接起第一帶狀光學膜4與第二帶狀 光學膜5。接著,相同地,在第二帶狀光學膜5之長度變得 較貼合至基板10所需長度更短的情況下,藉由膜連接單元 連接起第二帶狀光學膜5與第三帶狀光學膜18。 藉由前述結構,可將光學膜連續地貼合至基板10。以 下,使用第8圖和第9圖來更具體說明。 第8圖係顯示本實施形態之光學膜貼合方法一例的流 程圖。又,第9圖係顯示在第8圖所示流程圖之各步驟中, 光學膜貼合裝置示意圖之俯視圖。 如第8圖所示,本實施形態之光學膜貼合方法係反覆 進行後述步驟:以全新料卷(帶狀光學膜料卷1)進行一般 作業方式(步驟1);進行捲曲料卷(1)(第二帶狀光學膜 5)之膜連接(步驟2);以捲曲料卷(1)(第二帶狀光學膜 5)進行一般作業方式(步驟3);進行捲曲料卷(2)(第三 帶狀光學膜18)之膜連接(步驟4);以捲曲料卷(2)(第 三帶狀光學膜18)進行一般作業方式(步驟5);進行全新 料卷(帶狀光學膜料卷Γ)之膜連接(步驟6)。 又,如第9圖所示,步驟1係將帶狀光學膜料卷1切 成第一帶狀光學膜4、第二帶狀光學膜5、及第三帶狀光學 膜18,並使用第一帶狀光學膜4來進行貼合步驟。執行步 驟1直到第一帶狀光學膜4之長度變得較貼合至基板所需 長度更短為止。 接著,在步驟2中,反轉第二帶狀光學膜5,使其朝向 位在第一帶狀光學膜4搬送方向上的預備滾芯20處移動之 16 201132501 後,將其連接至第一帶狀光學膜4。接著,使第三帶狀光學 膜18朝向第二帶狀光學膜5原先所在之處移動。 其後,步驟3係使用第二帶狀光學膜5來進行貼合步 驟。執行步驟3直到第二帶狀光學膜5之長度變得較貼合 至基板10所需長度更短為止。 接著,步驟4與步驟2相同,反轉第三帶狀光學膜18, 使其朝向位在第二帶狀光學膜5搬送方向上的預備滾芯20 處移動之後,將其連接至第二帶狀光學膜5。其後,步驟5 係使用第三帶狀光學膜18來進行貼合步驟。執行步驟5直 到第三帶狀光學膜18之長度變得較貼合至基板10所需長 度更短為止。另外,在前述步驟2至步驟5之期間内,將 帶狀光學膜料卷1更換成全新帶狀光學膜料卷Γ。 接著,最後在步驟6中,將全新帶狀光學膜料卷1'連 接至第三帶狀光學膜18。如此一來,藉由反覆地進行步驟 1至步驟6,便可將光學膜連續地貼合至基板。 另外,在前述各實施形態中,雖然說明了帶狀光學膜 料卷1之寬度為基板10之相對應寬度的2倍或3倍之情 況,但本發明並不限於此。帶狀光學膜料卷之寬度只要是 基板之相對應寬度的2倍以上即可,較佳地,為該基板之 相對應寬度的η倍(η為2以上的整數)。僅管沒有特別限 定帶狀光學膜料卷之寬度的上限,但就處理層面來說,為 基板之相對應寬度的3倍以下者為佳。 又,在前述各實施形態中,該切斷單元係沿其長邊方 向將捲出後之該帶狀光學膜料卷切成二至三份,切成具有 17 201132501 對應該基板寬度的第—三帶狀光學膜。即,雖然說明了 沿其長邊方向將捲出後之帶狀光學膜料卷切成n份,切成 具有對應該基板寬度的第一〜η帶狀光學膜之情兄,彳曰本發 明不限於此。 舉例而言,亦可階段性地進行該切斷步驟。具體而古, 例如當帶狀光學膜料卷之寬度約為基板之相對應寬产的1 3 倍以上時,將捲出後之帶狀光學膜料卷切成具有基=之相 對應寬度的第一帶狀光學膜、以及具有剩餘寬度2帶狀光 學膜;捲曲後者之帶狀光學膜後,捲曲好之帶狀光學膜之 寬度則變成基板之相對應寬度2倍以上。因&,舉例^言, 在將捲曲好之該帶狀光學膜搬送至貼合步驟之前,只要^藉 由切斷步驟來將該膜之寬度切成基板之相對應寬度了便^ 與前述各實施形態同樣地將光學膜連續地貼合至基板。 又’舉例而§ ’當帶狀光學膜料卷之寬度達該基板之 相對應寬度的η倍以上且未滿(n+1)倍的情況,該切斷步 驟亦可/σ其長邊方向將捲出後之該帶狀光學膜料卷切成η 知,切成具有對應該基板寬度之第一〜(η—1)帶狀光學 膜、以及比基板之相對應寬度更寬的第η帶狀光學膜,而 在使用第η帶狀光學膜來進行貼合步驟之前將其端部切 除,裁切成基板之相對應寬度。 此外,取代前述方法,在帶狀光學膜料卷之寬度達該 基板之相對應寬度的η倍以上且未滿(η+1)倍的情況,該 切斷步驟亦可沿其長邊方向將捲出後之該帶狀光學膜料卷 切成(η+1)份,切成具有對應該基板寬度的第一〜η帶狀 18 201132501 光學膜、以及比基板之相對應寬度更窄的帶狀光學膜。在 這個情況中,除了寬度較窄之該帶狀光學膜無法用於貼合 步驟之外,其餘皆與前述各實施形態相同。 又,在前述各實施形態中,雖然說明了相對基板而僅 以單一方向(1轴)來貼合光學膜的結構,但本發明的範圍 並不限定於此。以雙方向(2軸)來進行貼合的結構亦可達 成幾乎相同的效果。 〔Π〕光學顯示裝置之製造方法 本實施形態之光學顯示裝置製造方法係包含:藉由前

The optical film bonding method of this embodiment will be described. (a) Ribbon-shaped optical film roll The strip-shaped optical film roll 1 may be composed only of an optical film. It may also be a structure in which other layers are laminated. The optical film may be exemplified by a polarizing film, Phase difference film, etc. A composite film in which two or more of these are combined may be used. 201132501 In addition, In this embodiment, It will be explained that an adhesive layer is laminated on the optical film in this order, An example of a release film. For example, When an optical film is attached to a 32-inch display device substrate, The width of the strip-shaped optical film roll 1 can be 1200 to 1400 mm. In this case, The front section is used for three parts. The latter part is used twice. (b) Substrate The substrate 10 can be exemplified for use in a liquid crystal display substrate, Plasma display substrate, Organic EL substrate, TFT substrate, A glass substrate such as a printed circuit board, a synthetic resin substrate, or the like can also be used to form a battery cell (Cell) in advance. A substrate of a component such as an electrode. (c) Unwinding step The unwinding step is a step of winding the strip-shaped optical film roll in the longitudinal direction thereof. In this embodiment, As shown in Figure 1, As the unwinding unit, the strip-shaped optical film roll 1 is conveyed by the transfer drum 6 sandwiched between the both sides of the optical film roll 1 . (d) Cutting step A cutting step is performed by cutting the strip-shaped optical film roll 1 after being rolled out along the longitudinal direction thereof. Cutting into a first strip-shaped optical film having a width corresponding to the substrate 10, And a step of the strip-shaped optical film having the remaining width. In this embodiment, Ribbon optical film roll! The width is twice the corresponding width of the substrate 10. Therefore, in the cutting step, The strip-shaped optical switch is cut into two by the cutting unit 8 along its long side direction, The city has a first strip-shaped optical film 4 and a second strip-shaped optical film 5 of a corresponding width of the substrate 1G. 201132501 The cutting unit 8 can be exemplified by various cutting edges or laser cutting devices.

(j) Feeding connection steps In this embodiment, After the length of the second strip-shaped optical film 5 becomes shorter than the length required to be bonded to the substrate 10, Also includes: Roll connection step, The second ribbon optical film 5 is connected to the replaced new ribbon optical film roll. In this embodiment, The roll joining step can be carried out by the film joining unit as described above in the same manner as the film joining step. However, it can also be done by manual work. In addition, For example, The membrane connecting unit of this embodiment can be exemplified by a computer control. The structure of the above-described film connecting step and each step described later is automatically performed. The winding connection step of this embodiment will be described using Fig. 4 .

Step 3 is performed until the length of the second strip-shaped optical film 5 becomes shorter than the length required for bonding to the substrate 10. During this period, Replace the strip of optical film roll 1 with a new strip of optical film roll. then, In step 4, A new ribbon optical film roll is attached to the second strip optical film 5. As a result, By performing the foregoing steps 1 to 4 repeatedly, The optical film can be continuously attached to the substrate 10. (Second embodiment) Hereinafter, a second embodiment of the present invention will be described in detail using Figs. 7 to 9 . but, When it is the same component as the user of the first embodiment, The same component symbols are given and the description is omitted. In this embodiment, Except that the width of the strip-shaped optical film roll 1 is 3 times the corresponding width of the substrate 10, The other structures are almost the same as in the first embodiment. Fig. 7 is a front view showing a schematic configuration of another example of the optical film bonding apparatus of the embodiment. As shown in Figure 7, In the optical film bonding apparatus of the embodiment, Different from the structure shown in Figure 1, The width of the strip-shaped optical film roll 1 is three times the corresponding width of the substrate 10. therefore, The strip-shaped optical film roll 1 is taken up by the cutting unit 8 in the longitudinal direction thereof, Will be cut into a first strip-shaped optical film 4 having a width corresponding to the substrate 10, Second strip optical film 5, And a third strip optical film 18. then, Each of them is transported by a roller 7, The second strip-shaped optical film 5 and the third strip-shaped optical film 18 are curled 7'. then, In the case where the length of the first strip-shaped optical film 4 becomes shorter than the length required to be bonded to the substrate 10, Same as the first embodiment described above 15 201132501 The first strip-shaped optical film 4 and the second strip-shaped optical film 5 are joined by a film connecting unit. then, identically, In the case where the length of the second strip-shaped optical film 5 becomes shorter than the length required to be bonded to the substrate 10, The second strip-shaped optical film 5 and the third strip-shaped optical film 18 are joined by a film connecting unit. With the aforementioned structure, The optical film can be continuously attached to the substrate 10. the following, More detailed description will be made using Figs. 8 and 9. Fig. 8 is a flow chart showing an example of the optical film bonding method of the embodiment. also, Figure 9 shows the steps in the flow chart shown in Figure 8, A top view of a schematic view of an optical film bonding apparatus. As shown in Figure 8, The optical film bonding method of the present embodiment repeats the steps described later: Carry out the general operation mode (step 1) with a new coil (belt optical film roll 1); Performing a film connection of the crimped roll (1) (second strip optical film 5) (step 2); Carrying out the general operation mode (step 3) with the crimped roll (1) (second strip optical film 5); Performing a film connection of the crimped roll (2) (third strip optical film 18) (step 4); Carrying out the general operation mode (step 5) with the crimped roll (2) (third strip optical film 18); Perform a film connection of the new roll (strip optical film roll) (step 6). also, As shown in Figure 9, Step 1 is to cut the strip-shaped optical film roll 1 into a first strip-shaped optical film 4, Second strip optical film 5, And a third strip optical film 18, The first strip optical film 4 is used to perform the bonding step. Step 1 is performed until the length of the first strip-shaped optical film 4 becomes shorter than the length required to be bonded to the substrate. then, In step 2, Inverting the second strip optical film 5, After moving toward the preliminary roll core 20 in the transport direction of the first strip-shaped optical film 4, 16 201132501 It is attached to the first strip-shaped optical film 4. then, The third strip-shaped optical film 18 is moved toward where the second strip-shaped optical film 5 was originally located. Thereafter, In step 3, the second strip optical film 5 is used for the bonding step. Step 3 is performed until the length of the second strip-shaped optical film 5 becomes closer to the length required for the substrate 10 to be shorter. then, Step 4 is the same as step 2, Inverting the third strip optical film 18, After moving toward the preliminary roll core 20 in the transport direction of the second strip-shaped optical film 5, It is connected to the second strip-shaped optical film 5. Thereafter, Step 5 The third strip optical film 18 is used for the bonding step. Step 5 is performed until the length of the third strip-shaped optical film 18 becomes shorter than the length required to be bonded to the substrate 10. In addition, During the aforementioned steps 2 to 5, Replace the strip of optical film roll 1 with a new strip of optical film roll. then, Finally in step 6, A new strip of optical film roll 1' is attached to the third ribbon optical film 18. As a result, By repeating steps 1 through 6, The optical film can be continuously attached to the substrate. In addition, In each of the foregoing embodiments, Although it is explained that the width of the strip-shaped optical film roll 1 is twice or three times the corresponding width of the substrate 10, However, the invention is not limited to this. The width of the strip-shaped optical film roll may be twice or more the corresponding width of the substrate, Preferably, It is η times the corresponding width of the substrate (η is an integer of 2 or more). Although the upper limit of the width of the strip optical film roll is not particularly limited, But as far as the processing level is concerned, It is preferably 3 times or less of the corresponding width of the substrate. also, In each of the foregoing embodiments, The cutting unit cuts the strip of optical film roll after being rolled out in two to three portions along the longitudinal direction thereof. Cut into a third-strip optical film having a width of 17 201132501 corresponding to the substrate. which is, Although it is described that the strip-shaped optical film roll after being rolled out in the longitudinal direction thereof is cut into n parts, Cut into the first ~ η ribbon optical film with the width of the substrate, The present invention is not limited to this. For example, This cutting step can also be carried out in stages. Concrete and ancient, For example, when the width of the strip-shaped optical film roll is about 13 times or more of the corresponding wide yield of the substrate, Rolling the strip-shaped optical film roll after being rolled out into a first strip-shaped optical film having a corresponding width of the base = And a strip-shaped optical film having a remaining width; After crimping the strip optical film of the latter, The width of the ribbon optical film which is crimped is more than twice the corresponding width of the substrate. Because & , Example ^, Before transporting the ribbon optical film that has been crimped to the bonding step, When the width of the film is cut into the corresponding width of the substrate by the cutting step, the optical film is continuously bonded to the substrate in the same manner as in the above embodiments. Further, by way of example, when the width of the strip-shaped optical film roll is η times or more and less than (n+1) times the corresponding width of the substrate, The cutting step can also cut the strip-shaped optical film roll after being rolled out in the longitudinal direction of σ, Cutting into a first ~ (η - 1) strip optical film having a width corresponding to the substrate, And an n-th ribbon optical film having a wider width than the substrate, And the end portion is cut off before the bonding step is performed using the η-belt optical film. The corresponding width of the substrate is cut. In addition, In place of the aforementioned method, In the case where the width of the strip-shaped optical film roll is more than η times the corresponding width of the substrate and less than (η+1) times, The cutting step may also roll the strip-shaped optical film roll after being rolled out in the longitudinal direction thereof into (n+1) parts. Cut into a first ~ η strip shape corresponding to the width of the substrate 18 201132501 optical film, And a strip-shaped optical film having a narrower width than the corresponding substrate. In this case, In addition to the narrow width of the ribbon optical film cannot be used for the bonding step, The rest are the same as in the above embodiments. also, In each of the foregoing embodiments, Although the structure in which the optical film is bonded in only one direction (one axis) with respect to the substrate is described, However, the scope of the invention is not limited thereto. A structure that is bonded in both directions (two axes) can achieve almost the same effect. [Π] Method of Manufacturing Optical Display Device The optical display device manufacturing method of the present embodiment includes: According to the optical film bonding method of the present embodiment described above, The step of continuously bonding the optical film to the substrate. Other necessary steps for manufacturing an optical display device, This can be suitably carried out by a conventionally known method. Preferably, In the optical film bonding apparatus of the present invention, The width of the strip-shaped optical film roll is about η times the corresponding width of the substrate (η is an integer of 2 or more). The cutting unit cuts the strip-shaped optical film roll after being rolled out in the longitudinal direction thereof into n parts. Cutting into a first-n ribbon optical film having a width corresponding to the substrate, The crimping unit, respectively, curls the second to n-band optical films. According to the structure, Since the cutting unit cuts the strip-shaped optical film roll after being rolled out in the longitudinal direction thereof into n parts, Cutting into a first to η ribbon optical film having a width corresponding to the substrate, in other words, The first to n-band optical film systems each have a width corresponding to the substrate. therefore, After the films are connected to each other, It can be fitted without additional cutting steps. The optical film can be bonded at a more efficient rate. 19 201132501 Preferably, The optical film bonding apparatus of the present invention further comprises: Membrane connection unit, After the length of the first strip-shaped optical film becomes shorter than the length required to fit the substrate, Connecting the first strip optical film and the second strip optical film, Thereafter, the same, After the length of the second ~(n-1) strip optical film becomes shorter than the length required to be bonded to the substrate, Connecting the second ~ (n-1) strip optical film and the third ~ n strip optical film; And a second roll-out unit, The strip-shaped optical film that is attached is rolled up toward the bonding unit. According to the structure, Even if the length of the optical film roll becomes shorter, With the membrane connection unit and the second take-up unit, The bonding can be continued immediately with the second to η ribbon optical film. and so, Due to the reduced number of replacements of the optical film roll, The optical film can be attached with higher efficiency. In addition, Since only the first-two-band optical film is used in the case of η=2, Then, the film connecting unit is naturally after the length of the first strip-shaped optical film becomes shorter than the length required to be bonded to the substrate, It is only used to connect the first strip-shaped optical film and the second strip-shaped optical film. Preferably, In the optical film bonding apparatus of the present invention, The film connecting unit will have a shorter length when the length of the first strip-shaped optical film becomes closer to the substrate. Rotating the second strip-shaped optical film such that the curling direction of the second strip-shaped optical film is in the same direction as the unwinding direction of the first strip-shaped optical film Connecting the first strip optical film and the second strip optical film, Thereafter, the same, When the length of the second ~ (η_1) ribbon optical film becomes shorter than the length required to be bonded to the substrate, After rotating the third to η ribbon optical film so that the winding direction of the third to η ribbon optical film which is preferably curled is in the same direction as the winding direction of the second (η-1) ribbon optical film, Connection 20 201132501 Second ~ (η-1) ribbon optical film and third ~ η ribbon optical film. According to the structure, Since the film connection can be made more easily, Therefore, the optical film can be attached with higher efficiency. In addition, Since only the first to second strip optical films are used in the case of η=2, Then, the film connecting unit is naturally after the length of the first strip-shaped optical film becomes shorter than the length required to be bonded to the substrate, Rotating the second strip-shaped optical film such that the curling direction of the second strip-shaped optical film is in the same direction as the unwinding direction of the first strip-shaped optical film It is only used to connect the first strip optical film and the second strip optical film. Preferably, In the optical film bonding apparatus of the present invention, The film connecting unit may be shorter after the length of the η-belt optical film becomes closer to the substrate. The n-th ribbon optical film and the new strip optical film are connected. According to the structure, Since the film connection of the new ribbon optical film roll can be made easier, Therefore, the bonding of the optical film can be performed with higher efficiency. The optical film bonding method of the present invention solves the aforementioned problems, The optical film is continuously attached to the substrate by using a roll of ribbon-shaped optical film roll. among them, The width of the strip-shaped optical film roll is more than twice the corresponding width of the substrate, And repeatedly carry out a series of steps including the following: Roll out the steps, Rolling the strip of optical film material along its longitudinal direction; Cutting off the steps, Cutting the strip of optical film material after being rolled out along the longitudinal direction thereof, Cutting into a first strip-shaped optical film having a width corresponding to the substrate, And a strip-shaped optical film having the remaining width; Fit step, Laminating the first ribbon optical film to the substrate; And the curling step, A strip-shaped optical film having a remaining width is crimped. 21 201132501 According to this method, Due to the inclusion of the cutting step, Even if the width of the optical film roll is not pre-cut to the corresponding width of the substrate, It is also possible to bond the optical film continuously to the substrate. therefore, The step of pre-cutting the width of the optical lap to the corresponding width of the substrate may be omitted. The optical film can be attached to the substrate with higher efficiency. also, Since the number of steps is omitted, It can reduce external defects such as biting or sticking of foreign objects caused by the handling between the steps. 'In addition' according to this method, The strip-shaped optical film having the remaining width may be additionally crimped while the first optical film is attached to the substrate. therefore, In the case where the length of the braided optical film becomes shorter than the length required for bonding to the substrate, , As long as the first optical film and the curled ribbon optical film are connected, You can continue to fit immediately after replacing it with Wang Xin Optical. In short, It can reduce the number of replacements of optical film rolls. The effect of the film, therefore, According to the method, It can achieve the bonding optics with higher efficiency. The optical 貘 fitter of the invention: The width of the roll is approximately „ times the corresponding width of the substrate. Give, # , The strip-shaped optical material roll is cut off after the long-side direction is rolled out, Shouting the corresponding width of the substrate -~: membrane, The crimping step will each curl the second to n-band optical film. The second two: After the breaking step, the strip-shaped optical film of the rolled-out degree along the longitudinal direction thereof has a corresponding one-n-n ribbon optical film corresponding to the substrate, No need to cut this extra, The films can be bonded to each other by connecting them to each other. The optical film can be laminated at a higher efficiency 22 201132501 rate. Preferably, In the optical film bonding method of the present invention, It has a membrane connection step. When the length of the first strip-shaped optical film becomes shorter than the length required for bonding to the substrate, Connecting the first strip optical film and the second strip optical film, Thereafter, the same, When the length of the second ~ (n-1) strip optical film becomes shorter than the length required to conform to the substrate, Connecting the second ~ (n-1) strip optical film and the third ~ n strip optical film; And by " Repeatingly performing the second roll-out step of winding the connected strip-shaped optical film in the longitudinal direction thereof, And a series of steps of bonding the attached strip-shaped optical film to the substrate, and the like. The optical film can be more continuously attached to the substrate. According to the method, Even if the length of the optical film roll becomes shorter, However, the film connection step and the second roll-out step can also be used. The bonding can be continued immediately with the second to η ribbon optical film. and so, Since the number of replacements of the optical film roll is reduced, Therefore, the optical film can be attached with higher efficiency. , In addition, Since only the first to second strip optical _ films are used in the case of η=2, Then, the film connecting step is naturally after the length of the first strip-shaped optical film becomes shorter than the length required to be bonded to the substrate, It is only used to connect the first strip optical film to the second strip optical film. Preferably, In the optical film bonding method of the present invention, The film connecting step is shorter when the length of the first strip-shaped optical film becomes closer to the desired length of the substrate. After the second strip-shaped optical film is rotated such that the curling direction of the second strip-shaped optical film is in the same direction as the unwinding direction of the first strip-shaped optical film, Connecting the first strip optical film and the second strip optical film, 23 201132501 Since then, When the length of the second ~ (n-1) strip optical film becomes shorter than the length required for bonding to the substrate, Rotating the third to n-belt optical films such that the winding direction of the curled third to n-belt optical film is in the same direction as the winding direction of the second to (n-1) ribbon optical film , The second ~ (n-1) strip optical film and the third to n strip optical film are connected. According to the method, Since the film connection can be made more easily, Therefore, the optical film can be attached with higher efficiency. In addition, Since only the first to second ribbon optical films are used in the case of η = 2, Then, the film connecting step is naturally after the length of the first strip-shaped optical film becomes shorter than the length required to be bonded to the substrate, After the second strip-shaped optical film is rotated such that the winding direction of the second strip-shaped optical film which is curled is in the same direction as the unwinding direction of the first strip-shaped optical film, It is only used to connect the first strip-shaped optical film and the second strip-shaped optical film. Preferably, In the optical film bonding method of the present invention, After the first ribbon optical film and the second ribbon optical film are connected, Before the length of the η-belt optical film becomes shorter than the length required to be bonded to the substrate, The strip of optical film was replaced with a new strip of optical film roll that was crimped into a roll. According to the method, In the case where the length of the n-th optical film becomes shorter than the required length of the substrate, Immediately with the new ribbon optical film roll for film connection, And immediately continue to fit. therefore, The optical film can be bonded more efficiently. Preferably, In the optical film bonding method of the present invention, After the length of the n-th ribbon optical film becomes shorter than the length required to conform to the substrate, Further package 24 201132501 comprises a roll joining step of joining the n-th ribbon optical film to the new strip optical film that has been replaced.
