玖、發明說明 ：發明觸之麟賴、先前技術、岐、實㈣式及®^單說剛 本發明係關於—種顯示裝置，該型顯示裝置中呈有 個配置於兩電極組之間的發光元件。尤甚者，本發日卿於 一種有機發光二極體(LED)顯示器，可為一種彩色顯示器。 先前技術
目可之g高分子發光二極體（Poly-LED)和有機發光二極體 (ED)〗、、員不态之缺點在於發光二極體層的電容值相對較 =。原因在於發光二極體非常地薄（約3〇〇奈米卜對於大型 顯示器而言，電容妨礙或甚至阻止被動式矩陣之運作，因 為置換兒級與發光二極體中用於產生光之電流相較變得太 大這使得執道中之驅動、功率消耗不精確且驅動器有大 電流。 發明内容· 本叙明之目的在於解決這些問題並提供一種改良型發 光二極體顯示器。 x

第二組中之其中一個條體 背離第二組中之其中一個 中之一個交錯處與一發光 定之發光元件。一種方式為除了 外朝所有條體吸引箔片，並同時 條體吸引箱片。這將僅使導電層 元件接觸。 實施方式 引用圖丨’一顯示單元10包含-前端極板1，其中複數個 例如ΠΓΟ(氧化銦錫）電極之透明行電極W沉積於該前端極 板1上。複數個發光元件3係形成於該等電極上。 發光元件3可為有機電致發光裝置，如p〇iyLED(高分子發 光二極體）或Ο-LED(有機發光二極體），但理論上亦可使^ 非有機性發光二極體。即使底下之說明主要將與高分子發 光二極體有關’仍用不著將其視為對本揭露發明之限制。 高分子發光二極體3之組成包含已提到之IT◦電極層（陽 極）、-由例如PED〇T/PPS(聚㈣雙氧園μ 乙稀磺酸納）所製成之電洞注入層、—由例如ρρν(聚對位苯 基乙稀)所製成之發光層、一由例如鋇或其它材料所製成之 注入層(陰極）、以及一由例如鋁或其它材料所製成之覆蓋 層。注入層與覆蓋層之圖樣應製成貼片3，每一個貼片皆對 應至-或多個像素並在前端極板丨之表面上形成規律之列 與行。在本文件中視為發光元件3的就是這些貼片，亦即所 描给之實施例中除了電極層外之發光二極體。 另外，顯示單元10包含-後端極板4，該後端極板4具有 用於運作-可機電運作式之導電列電極5。該等電極 可藉由-絕緣層予以覆蓋。由例如—種如帕轉（paiyiene) (4) (4)200304106 發明說明續寅 或聚亞醯膜(P〇丨yimide)之可蒸發性聚合物所製 運作式W6係配置於前端極板與後端極板之間 : 向前端極板1與行電極2之側邊係由一種例如銀1入” 所製成之導電層7予以被覆。導電層7可施以圖樣分二 即覆盖整個箔片表面’但亦可以對應於發光二極體 素群)之方式施以圖樣製作。若列電極係以一種絕二二 覆盍’則整個’;自片6係或選性地由導電材料予以製 在圖2、3所描繪之實施例中，羯片係由分置：側之 層8、9:以支承在適當位置而分別與前端及後蠕極板丨、4 :觸。W端極板與後端極板上間隔層之尺寸等級為…微 圖2表示非動入模式時之顯示器，亦即電源關閉且 極2、5皆處於零電位時之狀態。圖3表示運作期 ^ 示器。在此實例中，一正Γ弋名 π上 J 4 ., 、 （或負，取決於镇片6之特性）電厣 “加至列電極5。因此’荡片6係受到電極5之„及引，且： 強制朝向’有可能背離’電極5移動。…中視物 ^之W層7係接地的。之後，—列5㈣藉由將對應 丁〜擇使侍 > 白片6中與列電極相鄰之列 :再強制朝電極移動。接著，-行係藉由將一正(或負) 电壓施加至..前端極板〗上相對應之行電極h而予以選擇二 :中對應於所選列2a與行5a交錯處之區域h現在將受到行 :心之吸引亚強制朝向並背離置於該點之發光二極體3a ^動。當接地之Μ電極7與發光二極仏接觸時，—電产 订電極&流經發光二極體3a及箱片6上接地之導電層7。^ (5) 200304106
由於通過二極體3 a之電流將消除箔片電極7與發光二極 體3 a之間的電位差，故吸引力將有可能消失而使箔片6與發 光一極體3 a分開。一旦發生這種情形，發光二極體3 &將再 次經由行電極2予以充電，且箔片6係再次受到吸引。為了 避免該種可能發生於箔片6與行電極2之間的振盪作用，或 為了其它理由’可考慮許多其它替代之具體實施例。
根據此一具體實施例，發光二極體區之一部分，例如像 素側，係藉由厚度與發光二極體層大約相等之絕緣貼片予 以取代。因此，未使行電極之這個區域與導電層7接觸，藉 以至少在這個區域的周圍招致某種程度之吸引力。
根據圖4、5所描繪之另一具體實施例，前端極板側上之 間隔層8係予以移除，致使箱片6在非動作狀態時藉由其餘 之間隔層9與發光二極體3接觸，如圖4所示。當顯示器如圖 5所不動作時，箔片係受到電極5之吸引，類似於圖3所示之 顯示器。然而，當一選擇之列電極5a接地時，羯片6中與列 包5a鄰接之列區段在此實例中將背離前端極板1之行電 極2而又到推離。行電極2現在可用於使發光二極體3之此列 中選擇之像素動作。如圖4、5所示，面向間隔層9,發光二 極體可藉由-絕緣區1Q予以分開。此絕緣區在這些區域中 防止導電層與發光二極體接觸。 同樣地，工作函數不同之材料可分別用於羯片電極和發 、， ^右這些材料呈電性連接，一“真空程度感應式，， 電場繼續存在:&千t 、 、 生剩餘之吸引力，即發光二極體係經由 導電層7放電。 -10- 200304106 (6) - 發明說钥纜頁 一驅動架構之實施例係示於圖6。在此實施例中，資訊係 一次一條線地予以寫入且亮度係由脈寬調變所控制^ 7 四條描繪出之列電極上所施加之電壓係標示為1 &至1 :如時間區段之劃分所示，該等列中電壓電位為零之列一 次僅為一條。這些信號中不需要調變，因為目的為 時間“釋放”一特定之列電極。 v' 施加至四條描繪出之行電極中其中一行之電壓係標示為 12。如時間區段之劃分所示，寬度不同之電壓脈波12“係 饋=至電極。第—脈波⑺將與饋送—零電壓予首列列電極 • Ilia致，使發光二極體13a致動。第二脈波12b將對 發光二極體13b產生類似動作，依此類推。 由於發光二極體之亮度主要係由電流予以決定，使用電 _而非電壓驅動方式係明智的。排除使用固定電流/脈 波I度調變，亮度亦可用固定寬度/電流調變r振幅”調變） "^ 為了得到更高的灰階，可使用一由脈波寬度與 卜卜艾之、、且σ。對於列及行之切換電壓等級可為]0伏特 。、泊片之切換時間等級可為1微秒，其中1微秒之等級係適 用於一次一條線之驅動方式。 ”、、友之驅動方式的缺點在於流經發光二極體之 值相對齡古..、上八 广—‘呵。足έ降低效率。利用箔片之記憶特性以子圖 —方式驅動面板可能因而受到考慮。在那種實例中， 電流可對時間作f &八& 、， 、 ^ 更夕刀佈。然而，前提在於適當之記憶作 用k可得到的（致吾 # 有以上之描述），且發光二極體係非常同 負性地運作。右 _ 在那種貫例中，非同質性會導致一種不均衝 200304106 之電流分佈。另外，驅動器之電容性負載在子圖欄定址期 間係動態增加的，因為在定址週期中，已使部分列與羯片 接觸。雖然子圖欄型之定址係可行的，直前式一次一條線 架構仍是最好之選擇。 應注意許多上述較佳具體實施例之修改可由本行人士予 以實現。例如，其它合適之材料可用於箔片或電極。同樣 地’箔片在電極之間可用不同方式予以配置，只要能達到 希望得到的功能就好。理論上’本發明可基於兩電極組之 間的電流流向在任何一種類型之顯示器上予以實現，期望 能達到改良之像素定址。 圖式簡單說明 本發明在發明内容中之這些及其它觀點係引用附件之圖 式經由實施方式中更為清楚說明之較佳具體實施例而明顯。 圖1係根據-本發明具體實施例—發光二極體顯 之分解圖。 剖面圖。 面圖。 顯示單元在非動
