Abstract
本發明係關於包封膜,其可靠性評估方法,及包含彼之有機電子裝置及使用彼製造有機電子裝置之方法,並提供在將用於阻斷自外部引入的濕氣或氧進入有機電子裝置之包封膜施用於有機電子裝置之前,能夠預測包封膜之可靠性的可靠性評估方法,及在濕氣阻斷性能方面具有極佳可靠性的包封膜。
Description
本發明係關於包封膜,其可靠性評估方法,及包含彼之有機電子裝置,及使用彼製造有機電子裝置之方法。
有機電子裝置(OED)係包括使用電洞和電子產生電荷的交流電之有機材料層的裝置,且其例子可包括光伏打裝置、整流器、發射器、或有機發光二極體(OLED)等。
相較於現有的光源,以上的有機電子裝置中,有機發光二極體(OLED)的能量消耗較低且回應速率較快,且有利於顯示裝置或照明設備的薄化。此外,OLED亦具有空間利用性並因此而被預期施用於涵蓋各種可攜式裝置、螢幕、筆記型電腦、和TV的各種領域。
OLED的商品化和應用之擴展,最關鍵的問題是耐久性問題。OLED中所含的有機材料和金屬電極等極易被外在因素(例如濕氣)所氧化。為了要解決以上問
題,將用於阻斷濕氣的包封膜施用至有機電子裝置。
但是,在用於阻斷濕氣的包封膜施用至有機電子裝置之前,必須先核實性能,但在包封膜已整合金屬層的情況中,有著性能核實困難的問題。
本申請案提出在將用於阻斷自外部引入的濕氣或氧進入有機電子裝置之包封膜施用於有機電子裝置之前,能夠預測包封膜之可靠性的可靠性評估方法,及在濕氣阻斷性能方面具有極佳可靠性的包封膜。
本發明係關於包封膜和該包封膜的可靠性評估方法。該包封膜可施用於封裝或包封有機電子裝置,例如,OLED。此說明書中,“可靠性”是指關於包封膜之濕氣阻斷性能的可靠性。
此說明書中,“有機電子裝置”是指具有包含使用介於彼此面對的電極對之間的電洞和電子產生電荷的交流電之有機材料層之結構的物件或裝置,其例子可包括,但不限於,光伏打裝置、整流器、發射器和有機發光二極體(OLED)等。本發明的一個例子中,該有機電子裝置係OLED。
例示的包封膜可包含金屬層和形成於該金屬
層上的包封層。該包封層可包含濕氣吸附劑。一個例子中,該包封膜的可靠性評估方法包含根據以下等式1,該包封膜於550nm波長之對於包封層之鏡面反射率R為6.5或更低。即,可由本申請案之評估方法定出鏡面反射率R在6.5或更低的範圍內之包封膜具有極佳的可靠性。鏡面反射率之測定可藉由以具有550nm波長的光照射在形成於金屬層上的包封層的方式進行,此例如圖3中所示者。一個例子中,該包封膜具有根據以下等式1,於550nm波長之鏡面反射率R為6.5或更低的區域。
(等式1)R=SCI-SCE
以上的等式1中,SCI是包括根據ASTM E1164-12E1測得的正向反射之總反射率(含括鏡面向量,Specular Component Included,SCI),而SCE是排除根據ASTM E1164-12E1測得的正向反射之反射率(排除鏡面向量,Specular Component Excluded,SCE)。明確言之,SCI是指總反射率,而SCE是指藉散射造成的不規則反射率。反射率可藉此技術已知的方法測定,且例如,可以使用得自Konika Minolta的CM2006d測定(測定條件:M/I+E、M/SCI、M/SCE、S/I+E、S/SCI和S/SCE的任一組值,UV 0%至100%的任一組值,D65、D50、C、A、F2、F6、F7、F8、F10、F11和F12的任一光源,10°或2°的觀察視野)。
藉由將該包封膜的鏡面反射率控制於6.5或更低,6.3或更低,6.0或更低,或5.9或更低,本申請案可
提供高度可靠的膜作為濕氣阻擋膜。通常,含於膜中的濕氣吸附劑可降低因為與滲入膜內的濕氣之水合反應產生水合物而產生的散射,並因此可降低能夠與濕氣反應之有效的濕氣吸附劑聚集體的尺寸。此外,藉由因水合反應而造成之濕氣吸附劑的折射率變化,可達到與樹脂相符的折射率(即,折射率以類似的方式收斂)以降低折射率。因此,根據散射是否存在,僅藉濁度測定可測定該膜的可靠性。但是,當包封層和金屬層例如本發明之整合時,因為該金屬層,所以難根據透光性的存在與否,僅簡單地藉由測定濁度來核實可靠性。因此,本申請案藉由提供該金屬層和包封層整體來達到程序的便利性,並同時藉由例如等式1中測定鏡面反射率而提供可靠度高的膜。
在本申請案之具體實施例中,以下描述之本發明之包封樹脂的折射率在1.3至1.6的範圍內。該濕氣吸附劑的折射率是在1.6至2.5的範圍內。該包封樹脂的折射率低於該濕氣吸附劑的折射率。該折射率可使用Abbe折射計測定。
一個例子中,該包封膜之可靠性評估方法包含根據等式2,該包封膜的鏡面反射率r低為0.5或更低,0.3或更低,0.151或更低,0.150或更低,或0.147或更低。藉本申請案之可靠性評估方法可定出,鏡面反射率在以上述範圍內的該包封膜具有極佳的濕氣阻斷性能。
(等式2)r=(SCI-SCE)/SCI
以上的等式2中,SCI是包括根據ASTM E1164-12E1測得的正向反射之總反射率,而SCE是排除根據ASTM E1164-12E1測得的正向反射之反射率。此處,鏡面反射率的比是指鏡面反射率對總反射率的比。鏡面反射率的比為0.5或更低之包封膜係濕氣吸附劑的功能耗損較低者。在該包封膜的情況中,存在於該包封膜中的濕氣吸附劑的功能會因為在施用至有機電子裝置之前,在分佈和儲存期間內,吸收空氣中的濕氣而耗損。本申請案提出一種此種功能耗損最小化的膜。在一個例子中,該包封層的厚度在15μm至70μm的範圍內。本申請案可藉由將該包封層的厚度控制於15μm或更高而改良塗覆性,及藉由將厚度控制於70μm或更低以縮短乾燥時間而改良加工性。此外,該金屬層的厚度在20μm至150μm的範圍內。本申請案可藉由將該金屬層的厚度控制於20μm或更高而改良濕氣阻擋性,並藉由將厚度控制於150μm或更低而改良切割加工性。
在本申請案的具體實施例中,該金屬層可為薄金屬箔片或澱積有金屬的聚合物基底層。可以無限制地使用具有導熱性和濕氣阻擋性的材料作為該金屬層。該金屬層包含金屬、金屬氧化物、金屬氮化物、金屬碳化物、金屬氧氮化物、金屬氧硼化物、和其組合中之任一者。例如,該金屬層可包含其中一或多種金屬元素或非金屬元素加至一金屬中之合金,且可包含,例如,鐵-鎳合金或不銹鋼(SUS)。此外,在一個例子中,該金屬層包含銅、
鋁、鎳、氧化矽、氧化鋁、氧化鈦、氧化銦、氧化錫、氧化銦錫、氧化鉭、氧化鋯、氧化鈮、和其組合。該金屬層可藉電解、滾軋、熱蒸發、電子束蒸發、濺鍍、反應性濺鍍、化學蒸鍍、電漿化學蒸鍍或電子迴旋加速器共振電漿源化學蒸鍍的方式澱積。本發明的一個例子中,該金屬層可藉反應性濺鍍而澱積。
較佳地,該金屬層的導熱度為50W/mK或更高,60W/mK或更高,70W/mK或更高,80W/mK或更高,90W/mK或更高,100W/mK或更高,110W/mK或更高,120W/mK或更高,130W/mK或更高,140W/mK或更高,150W/mK或更高,200W/mK或更高,或250W/mK或更高。藉由具有此高導熱度,在該金屬層黏合程序期間內,在黏合界面處生成的熱可更迅速地釋出。此外,因為高導熱性,所以在有機電子裝置的操作中累積的熱會迅速釋放至外部,藉此而使得該有機電子裝置本身維持於較低溫度,且可減少破裂和缺陷的發生。
文中所用“導熱性”為材料藉傳導而轉移熱的能力之程度,其表示單位是W/mK。此單位是材料於相同溫度和距離的熱傳導程度,且是指相對於距離的單位(meter)和溫度的單位(kelvin)之熱的單位(watt)。
在一個例子中,在根據ASTM E1164-12E1測得之含括鏡面向量(SCI)測定中,該金屬層的反射率可為50%至80%,53%至77%,或55%至75%。此外,在根據ASTM E1164-12E1測得之排除鏡面向量(SCE)測定
中,該金屬層的反射率可為5%至35%,8%至33%,或10%至30%。此處,待測定的該金屬層的反射率可為沒有該包封層存在之該金屬層表面的反射率。藉由將該金屬層的反射率控制在上述範圍內,經由根據上述等式1之膜的鏡面反射率,本申請案可評估和提供可靠度高的膜。
在本申請案的具體實施例中,該包封層可包含壓敏性黏著組成物或黏著組成物,且在一個例子中,該包封層可包含包封樹脂。在一個例子中,該包封層可為單層或二或更多層的多層結構。當二或更多層構成該包封層時,該包封層中的各層之組成可相同或相異。在一個例子中,該包封層可為壓敏性黏著層或黏著層。

等。
上列樹脂或彈性體亦可以下列方式使用:例如,經順丁烯二酸酐等接枝、與其他樹脂或彈性體經由用於製造樹脂或彈性體之單體共聚、及藉由以其他化合物改質使用。以上的其他化合物的例子包括羧基終端的丁二烯-丙烯腈共聚物等。
在一個例子中,在作為包封樹脂的上述類型中,該包封層包含,但不限於,烯烴彈性體、聚矽氧彈性體或丙烯酸系彈性體等。

在該包封層中,該樹脂或彈性體組份具有可
使得該壓敏性黏著劑組成物可製成膜形狀之重量平均分子量(Mw)。例如,該樹脂或彈性體的重量平均分子量是約90,000至2,000,000,100,000至1,500,000,或100,000至1,000,000等。文中的“重量平均分子量”是藉GPC(凝膠穿透層析法)測得之相對於聚苯乙烯標準品的轉換值。但是,該樹脂或彈性體組份不一定得具有上述重量平均分子量。例如,在該樹脂或彈性體組份的分子量不足以形成膜的情況中,可將另外的黏合劑樹脂混入該壓敏性黏著劑組成物中。
另一具體實施例中,根據本申請案之包封樹脂可為可固化的樹脂。未特別限制可用於本申請案之可固化的樹脂的特定類型,且例如,可以使用此領域中已知之各種熱固化或光可固化的樹脂。“熱固化樹脂”是指可經由適當的施熱或老化程序加以固化的樹脂,而“光可固化的樹脂”是指可藉電磁波照射加以固化的樹脂。此外,可固化的樹脂亦可為包括熱固化和光可固化特徵二者之雙重可固化的樹脂。

該包封層可以另外包含濕氣吸附劑,此例如前述者。“濕氣吸附劑”是指,例如,能夠藉由與濕氣或水氣之化學反應移除滲入包封膜的濕氣或水氣之材料。當本申請案之包封層包含濕氣吸附劑時,可實現極佳的濕氣阻擋性。特定言之,在製成膜時,可施用該包封層以包封有機電子裝置。在此情況中,其包含濕氣吸附劑以展現極佳的濕氣阻擋性,藉此,其可用於包封底部發射型有機電子裝置,但不在此限。
例如,該濕氣吸附劑可以均勻分散的狀態存在於該包封層或該包封膜中。此處,均勻分散的狀態是指
該濕氣吸附劑以相同或實質上相同的密度均勻地存在於該包封層或該包封膜的任何部分。可用於上述之濕氣吸附劑可為濕氣反應性吸附劑,且例如,可包括金屬氧化物、硫酸鹽或有機金屬氧化物等。特定言之,硫酸鹽的例子包括硫酸鎂、硫酸鈉或硫酸鎳等,有機金屬氧化物的例子包括氧化鋁辛酸酯。此處,金屬氧化物的特定例子包括五氧化磷(P2O5)、氧化鋰(Li2O)、氧化鈉(Na2O)、氧化鋇(BaO)、氧化鈣(CaO)或氧化鎂(MgO)等,金屬鹽的例子包括硫酸鹽,例如硫酸鋰(Li2SO4)、硫酸鈉(Na2SO4)、硫酸鈣(CaSO4)、硫酸鎂(MgSO4)、硫酸鈷(CoSO4)、硫酸鎵(Ga2(SO4)3)、硫酸鈦(Ti(SO4)2)或硫酸鎳(NiSO4),金屬鹵化物,例如氯化鈣(CaCl2)、氯化鎂(MgCl2)、氯化鍶(SrCl2)、氯化釔(YCl3)、氯化銅(CuCl2)、氟化銫(CsF)、氟化鉭(TaF5)、氟化鈮(NbF5)、溴化鋰(LiBr)、溴化鈣(CaBr2)、溴化銫(CeBr3)、溴化硒(SeBr4)、溴化釩(VBr3)、溴化鎂(MgBr2)、碘化鋇(BaI2)或碘化鎂(MgI2);或金屬氯酸鹽,例如過氯酸鋇(Ba(ClO4)2)或過氯酸鎂(Mg(ClO4)2)等,但不在此限。由於該濕氣吸附劑可含括於該包封層中,所以亦可使用上述構份中之一或二或更多者。一個例子中,當使用二或更多者作為濕氣吸附劑時,可使用經煅燒的白雲石等。
此濕氣吸附劑可取決於其用途而控制於適當尺寸。在一個例子中,該濕氣吸附劑的平均粒子直徑可控
制於0.5μm至5μm,1μm至4μm,或2μm至3.5μm。尺寸在上述範圍內的濕氣吸附劑與濕氣的反應速率不會過快並因此而容易儲存,且可以有效地移除濕氣,不會損及待包封的元件。
未特別限制該濕氣吸附劑的含量且可考慮所所欲的阻斷性,適當地選擇濕氣吸附劑的含量。例如,該濕氣吸附劑的含量為5至100重量份,10至90重量份,或15至80重量份,此係基於100重量份的包封樹脂。
必要時,該包封層亦可另外包括濕氣阻斷劑。此說明書中,“濕氣阻斷劑”是指與濕氣不具反應性或反應性低,但可阻斷或阻礙濕氣或水氣在膜中之移動的材料。可以使用黏土、滑石、針狀矽石、板狀矽石、多孔矽石、沸石、氧化鈦或氧化鋯中之一或二或更多者作為濕氣阻斷劑。此外,該濕氣阻斷劑的表面亦可經有機改質劑之類處理以利於有機物質的滲透。所用的有機改質劑可為,例如,二甲基苄基氫化的牛油四級銨、二甲基氫化的牛油四級銨、甲基牛油雙-2-羥基乙基四級銨、二甲基氫化的牛油2-乙基己基四級銨、二甲基去氫化的牛油四級銨、或彼等之混合物等。
未特別限制該濕氣阻斷劑的含量且可以考慮所欲阻斷性而經適當地選擇。
除了上述組份以外,該包封層可包含各種添加劑,此取決於下文將描述之包封膜的應用和製程。例如,該包封層可包括適當含量範圍之可固化的材料、交聯
劑、填料之類,此取決於所欲的物理性質。
在本發明之具體實施例中,該包封層可製成單層構造,亦可製成二或更多層。例如,若其包含兩層,則第一和第二層分別可包含或不包含濕氣吸附劑。在一個例子中,不包含濕氣吸附劑的層可接合至以下描述的有機電子元件的整個表面,以與該元件接觸。
未特別限制第一層和作為額外積層之第二層的積層順序,且該第二層可形成於該第一層上,及反之,該第一層可形成於該第二層上。該包封層亦可由三或更多層所形成,且例如,該第一層可含括二或更多層,或該第二層可含括二或更多層。
本申請案亦係關於包封膜。該包封膜包含上述金屬層和形成於該金屬層的包封層上並包含濕氣吸附劑。根據以下等式1,該包封膜於550nm波長之對於包封層之鏡面反射率R為6.5或更低。
(等式1)R=SCI-SCE
以上的等式1中,SCI是包括根據ASTM E1164-12E1測得的正向反射之總反射率(含括鏡面向量,Specular Component Included,SCI),而SCE是排除根據ASTM E1164-12E1測得的正向反射之反射率(排除鏡面向量,Specular Component Excluded,SCE)。
藉由將該包封膜的鏡面反射率控制於6.5或更低,本申請案可提供高度可靠的膜作為濕氣阻擋膜。藉由
整合地提供該金屬膜和該包封層,本申請案可達成製程的便利性,並藉由測定等式1中的鏡面反射率,同時提供高度可靠的膜。
本申請案亦係關於有機電子裝置。例如圖2中所示,該有機電子裝置(3)包含基板(31);形成該於基板(31)上的有機電子元件(32);及用於包封該有機電子元件(32)之包封膜(33,34)。此處,該包封膜可包封,例如,該有機電子元件的頂面和側面的全部。該包封膜可包含包封層(33),該包封層(33)包含處於交聯狀態的壓敏性黏著劑組成物或黏著劑組成物。此外,該有機電子裝置之形成使得該包封層(33)與該有機電子元件的整個表面接觸。
此處,該有機電子元件可為,例如,有機發光元件。
本發明亦係關於製造有機電子裝置之方法。該有機電子裝置可使用,例如,該包封膜製得。
該包封層(33)可製成有效地固定和承載該基板(31)和該金屬層(34),且在有機電子裝置中同時展現極佳的濕氣阻擋性和光學特性之結構化的包封層(33)。
此外,無論該有機電子裝置的形式(例如,頂部發射或底部發射),該包封層可製成安定的包封層。
此說明書中,包封層是指覆蓋該有機電子元件的所有頂面和側面表面之壓敏性黏著劑。
為製造該有機電子裝置,例如,該方法之步驟包含將上述包封膜施用至已有有機電子元件形成於其上的基板,以覆蓋該有機電子元件;和固化該包封膜。該包封膜的固化步驟是指該包封層的交聯或固化。此處,該包封膜之施用可以使得該包封層完全包封該有機電子元件。
此說明書中,“固化”是指經由加熱或UV照射程序等而使得本發明之壓敏性黏著劑組成物形成交聯結構,並藉此製得壓敏性黏著劑。或者,亦是指黏著劑組成物製成黏著劑形式。
特定言之,藉由方法(例如,真空澱積或濺鍍),在作為基板的玻璃或聚合膜上形成透明電極,在透明電極上形成發光有機材料層(例如,由電洞傳輸層、發射層和電子傳輸層等所組成),及之後另外在其上形成電極層,可形成有機電子元件。之後,配置該包封膜的該包封層以覆蓋已進行上述程序之基板的有機電子元件的全部表面。
本發明提出一種包封膜,其可形成能夠有效地阻斷濕氣或氧自外部進入有機電子裝置的結構並可在施用至該有機電子裝置之前預測可靠性,及用於該包封膜之可靠性評估方法。
