以下根據本發明之一具體實施例提供以製造液晶顯示(LCD)裝置為例的技術,但是相同技術也有用於包括液體單元之其他類型電子裝置的製造,如下述。
圖1圖示透射型LCD裝置之一實施例,但是以下所描述的技術同樣也可應用於反射型LCD裝置。
透射型LCD裝置包含在兩個偏光鏡4、12之間的液晶單元10。
該透射型LCD裝置也包含電路8以獨立控制像素導體陣列中之每一者的電位以及藉此獨立控制用於各像素之液晶單元10的液晶材料之電場,以及藉此獨立控制用於各像素之液晶材料的一或更多光學性質。該電路可包含薄膜電晶體(TFT)的陣列,其包括用於各像素的一或更多TFT,以及定址導體用以從在主動顯示區中之一或更多邊緣外的一或更多驅動晶片來獨立定址用於各像素的TFT(或數個)中之一或更多的源極及閘極。以平面內切換(IPS)裝置為例,該電路也包含與像素導體在液晶材料之同一面上的共用導體。下述技術也可應用於其他種類的液晶裝置,其中該共用導體設在液體材料中與像素導體相反的側面上。

圖2及圖3圖示至少以單一層合製程製造多個LCD裝置之液晶單元的技術之一實施例。為使描述簡潔,圖2只圖示用於兩個LCD裝置的液晶單元,但是相同技術可用來以單一層合製程製造用於兩個以上之LCD裝置的液晶單元。
該層合技術涉及使可撓組件24層合至下層組件14,在圖示於圖2之區上已預先分配黏著劑16、20和液晶材料22。
用於各液晶單元的液晶材料22以線體22的形式分配,線體22與主動顯示區18的上游邊緣平行但是與其稍微隔開。
提供黏著劑16以在單元組裝期間防止脫層(delamination)以及可容納液晶材料。該黏著劑可以由黏著劑形成之連續線的形式沉積於區16、20中。
如圖2(其圖示間隔件結構在層合方向上(例如,沿著直線A-A)如何分布)的右半部所示,在下層及上層組件14、24中之至少一者上,間隔件結構32不僅設於主動顯示區18中,也在層合方向34上分布於在用於兩個LCD裝置的兩個主動顯示區18之間的整個中間區上。例如,間隔件結構32可形成下層組件14的整合部份。例如,可藉由以光刻方式圖案化下層組件14之絕緣體層來形成它們。例如,間隔件結構可包含數個柱體(在下層組件的平面中有實質相同的尺寸),及/或可包含在層合方向上有相對長尺寸和在垂直方向有相對短尺寸的肋條結構。
下層組件14本身可為可撓組件且在層合製程期間支撐在相對剛性載體26上。例如,下層組件14可包括塑膠支撐膜,其支撐濾光片陣列和由圖案化導體、半導體及絕緣體層組成的堆疊以界定由TFT、像素導體及定址導體組成的陣列用以從在主動顯示區18外的一或更多驅動晶片來定址該等TFT。上層組件24的尺寸及形狀可經製作成它可層合至下層組件14中含有定址電路的側面而不覆蓋定址電路在主動顯示區外的端子,例如,這些端子用於連接至要直接黏結至下層組件14之一或更多驅動晶片的端子。例如,上層組件24在上層組件的全長有小於下層組件14的寬度(與層合方向垂直的尺寸)。
可撓上層組件24也可包含LCD裝置的偏光鏡12及/或其他組件,例如用於某些類型之LCD裝置的共用導體(COM)。
下層及上層組件14、24也包含鄰近完成液晶單元之液晶材料的對準塗層,該等對準塗層影響液晶材料的分子取向。
該層合製程涉及使用滾筒28以連續地迫使可撓上層組件的遠端部份越來越多地壓著下層組件,同時可撓上層組件24的近端緊固至固定點36以使可撓上層組件24在滾筒28上游的部份(亦即,上層組件在滾筒28、固定點36之間的部份)保持處於拉伸狀態。該層合製程繼續直到滾筒28位於黏著劑的最遠端部份20上面(或在其外)。
在圖3中,以30標示的元件籠統表示間隔件結構32、黏著劑16及分配於下層組件14上的液晶材料22。在層合製程期間,LCD裝置的每一條液晶材料22變成遍佈於該LCD裝置的整個主動顯示區18。
本申請案發明人已發現,在兩個主動顯示區18之中間區域中含有間隔件結構32有助於防止黏著劑污染主動顯示區18及/或液晶單元中部份出現過多液晶材料。不希望受限於理論,吾等認為在中間區域之中的這些附加間隔件結構32是有效的,因為藉由為兩個主動顯示區之間的多餘液晶材料提供有相對大容積的井,它們減少任何多餘液晶材料從一主動顯示區蔓延進入(在層合方向上的)下一個主動顯示區18、且攜帶黏著材料16進入該下一個主動顯示區的風險。
在一具體實施例中,間隔件結構32在層合方向上至少均勻地分布於在兩個主動顯示區之間的中間區域之近端半部上面。在另一具體實施例中,間隔件結構32在層合方向上至少均勻地分布於在兩個主動顯示區之間的中間區域之遠端半部上面。在一具體實施例中,該等間隔件結構也位於在兩個主動顯示區之間的中間區域中未分配黏著劑材料之至少一部份中。
在圖示於圖4的一具體實施例中,在主動區區域18中的間隔件結構32a有與在中間區域中之間隔件結構32b不同的圖案。間隔件結構32a在主動區區域18中的圖案(相較於在中間區域中之間隔件結構32b的不同圖案)在下層及上層組件之間可更好地維持均勻的液體材料厚度;以及在中間區域中之間隔件結構32b的圖案(相較於在中間區域中之間隔件結構32a的圖案)在為兩個主動顯示區之間可更好地提供有相對大容積的井給多餘的液晶材料。
如上述,上述技術也有用於製造除液晶顯示裝置之外的電子裝置。例如,上述技術也有用於製造容納一液體功能材料於兩個組件之間的其他類型電子裝置,例如在兩個組件之間包含一電化學反應性液體材料的電子氣體感測器裝置,該電化學反應性液體材料在待感測氣體經由下層及上層組件中之一或更多者的孔而接觸該液體材料時與氣體化學反應,偵測該化學反應可用該裝置的電路。在此一感測裝置中,導體層中可界定間隔件結構,該導體層也界定一或更多導體而可經由它來偵測液體的電化學反應。
除了明確描述於上文的任何修改以外,熟諳此藝者明白上述具體實施例可做出各種其他修改而不脫離本發明的範疇。
