Description

200910297 九、發明說明 【發明所屬之技術領域】 本發明係有關有機電激發光（EL)被動矩陣元件之驅動 裝置，而更詳細係關於具備2個列驅動器之有機電激發光 被動矩陣元件之驅動裝置。 【先前技術】 有機EL元件係期待對於下世代顯示器之應用等。對 於爲了使有機EL元件發光之驅動方式之一，有被動矩陣 方式，在此方式中，將縱方向及橫方向的電極線構成爲格 子狀，使設置於各交點上之有機EL元件（相當於畫素）， 驅動於各線。 圖1係表示以被動矩陣方式所驅動之有機EL元件（以 下稱爲「有機EL被動矩陣元件」）之一般的驅動裝置。而 驅動裝置100係具備行（column)驅動器101及列（row)驅動器 102。有機EL被動矩陣元件1 10係由m列xn行之有機EL 元件所構成。而各有機EL元件之陽極側乃與行驅動器 1 〇 1之各輸出所連接，陰極側乃對各行，連接於列驅動器 1 02之各輸入。針對在此構成，僅由列驅動器1 〇2之陰極線 1成爲低電位之情況，與來自外部之亮度信號（未圖示）成 正比之電流I^Im乃流動於列方向而有機EL元件則亮燈 。接者，列驅動器1 0 2之陰極線2〜η乃依序成爲低電位， 將有機EL被動矩陣元件1 1 0，以行單位進行亮燈。爲所 謂稱作依序掃描之構成。驅動裝置1 00係經由其重複而將 200910297 預先訂定之模樣及畫像，顯示於有機EL被動矩陣元件 110° 爲了驅動驅動裝置100而最低必要之電源電壓vs係以 式（1)所表現，消耗電力 P係爲其電壓和合算驅動電流 Ii~Im後的I的積。
Vs = Vi + V2 + V3 + Vcm + V4 (1)
Vc,(i=l，2 ’…，m)係爲第i列之有機EL元件之陰極 端子，和連接其陰極端子之列驅動器1 0 2的輸入端子之間 的電壓降，Vem係爲從配置於第m列之有機EL元件之陰 極端子的電壓降。 電壓降Ve,(i=l，2，…，m)係爲經由第i列之有機EL 元件之陰極端子，和連接其陰極端子之列驅動器1 02的輸 入端子之間的配線（陰極線）之阻抗的構成，如圖2所示， 在行（畫素）方向增加（實際係並非直線上升，但方便上以 直線來圖示）。將r作爲各畫素間之配線阻抗，於全畫素 流動一定的電流I之情況，Vem係以式（2)所表現。
Vcm = I * r + 2I · r + 3I · r+ · . . +ml . r (2) 加上電源電壓Vs時，經由行（畫素）方向之電壓的差 ，存在有無效電力（相當於對於圖2之無效電壓V5乘上電 流的値）。其無效電力係成爲顯示畫面越大，越無法忽視 -5- 200910297 的値。 例如，在2_8英吋QVGA(240RGB畫素x3 2 0行）之情況 ，配線阻抗係各行的陰極線的全長約爲45mm，材料之鋁 的厚度在l〇〇nm時則爲1〇〇Ω程度。在此，當對於全畫素. 流動150μΑ時，電壓降Vem則爲5.7V。其部分的電力則成 爲5_7Vxl50pAx240x3 (RGB)。其値的一半係爲無效電力。 如此，在以單一之列驅動器吸收驅動電流之一般的驅動裝 置中，有著存在有過大之無效電力的問題。 於畫素方向，配線阻抗產生變化之情況係除了電力的 問題以外。有著引起亮度不勻之問題，而配線阻抗的差異 則帶來各畫素之啓動特性並且發光時之差異，而牽連到亮 度不勻。 對於專利文獻1係揭示有由將相當於列驅動器之陰極 線掃描電路，連接於相當於陰極線之陰極線的兩端情況， 解決消耗電力及亮度不勻之問題的技術。另外，對於專利 文獻2，亦揭示有同樣的技術。經由設置相當於列驅動器 之第1及第2之掃描線切換機構，將所選擇之掃描線（相當 於陰極線）進行接地之情況，減輕經由配線阻抗之顯示不 句的構成。 圖3係表示如記載於專利文獻1及2之驅動裝置。驅動 裝置3 00係具備行驅動器301，列驅動器3 02及列驅動器303 ’列驅動器302與3 03係配置於陰極線之兩端。 圖4係表示經由針對在具備2個列驅動器之驅動裝置之 配線阻抗的電壓降。由流動在陰極阻抗之電流，經由2個 -6- 200910297 列驅動器所吸收之情況’抑制配線阻抗之行（畫素）方向之 變化，特別是針對在陰極線之端，降低電壓降。 具體而言，例如’在2·8英吋 QVGA(240RGB畫素 X 3 2 0行）之情況，陰極線的全長乃單側約2 2 · 5 m m，鋁的厚 度當爲lOOnm時，電阻則成爲50Ω程度，當對於全畫素流 動150μΑ時，電壓降則爲1.4V。其部分的電力則成爲 1.4Vxl50pAx240x3(RGB)，無效電力係爲以往的1/4。另 外，列驅動器之電壓V4亦因成爲1/2，而更降低電源電壓 。如此，改善無效電力與陰極阻抗部分之電力。另外，當 在行（畫素）方向之電壓差降低時，啓動特性之差異則變小 ，亮度不勻亦降低。 顯示畫面的大型化係除因配線阻抗引起之問題以外， 亦帶來伴隨消耗電力之增加的問題。當顯示畫面大型化時 ’可流動電流於各行之時間則變短。例如，由一組之行驅 動器及列驅動器，驅動如2.8英吋 Q V G A (2 4 0 R G B畫素 X 320行）之大型有機EL被動矩陣元件之情況，掃描周期則 成爲1 /3 20。隨之，爲了確保所期望之亮度，有必要增加 電流’伴隨此’有機EL元件之消耗電力則增加。 對於專利文獻3係揭示有伴隨著畫面的大型化，採用 使用2個將行驅動器及列驅動器集成於1個晶片的LSI之雙 掃描方式之驅動裝置。經由使用2個L SI之情況，相較於1 個的情況’因可將可流動電流於各行的時間加長爲2倍程 度’故可將電流抑制爲較低。 [專利文獻1]日本特開平9-2 8 1 92 8號公報 200910297 [專利文獻2]日本特開2006-235162號公報 [專利文獻3]日本特開2006-47511號公報 【發明內容】 [發明所欲解決之課題] 如根據上述之以往技術，雖可降低因有機EL被動矩 陣元件之大型化所造成的消耗電力之增加或亮度不勻之發 生’但考量對於大型顯示器的應用等之情況，期望更能解 決此等之問題。並且，期望以低成本來實現此等。 本發明係有鑑於如此問題點而構成者，其目的係提供 低成本地實現有機電激發光被動矩陣元件之消耗電力的降 低及亮度不勻之抑制之有機電激發光被動矩陣元件之驅動 裝置。 [用以解決課題之手段] 爲了達成如此之目的，記載於申請專利範圍第1項之 發明，在於複數之陽極線與複數之陰極線配置呈格子狀， 於各交點，設置有有機電激發光元件之有機電激發光被動 矩陣元件之驅動裝置中，具備連接於前述複數之陽極線之 一端的行驅動器，和分別連接於前述複數之陰極線之兩端 之第1及第2之列驅動器。前述行驅動器係流動電流於前述 複數之陽極線之中被選擇之陽極線。前述第1及第2之列驅 動器係通過從前述複數之陰極線中被選擇之陰極線吸入由 前述行驅動器所流動的電流。然後’前述行驅動器與前述 -8 - 200910297 第1之列驅動器與前述第2之列驅動器乃集成於單一之IC 爲特徵者。 另外’記載於申請專利範圍第2項之發明’則在於申 請專利範圍第1項中，前述行驅動器乃接近前述1 c之周圍 之一邊而配置，前述第1及第2之列驅動器乃各別接近鄰接 於配置前述行驅動器之一邊的邊而配置者。 另外，記載於申請專利範圍第3項之發明’則在申請 專利範圍第1項中，前述行驅動器乃接近前述1 c之周圍之 一邊而配置，前述第1及第2之列驅動器乃呈彎曲’各別接 近前述行驅動器，和鄰接於配置前述行驅動器之一邊的邊 而配置者。 另外，記載於申請專利範圍第4項之發明，則將如申 請專利範圍第1項至第3項之任一項之有機電激發光被動矩 陣元件之驅動裝置，一個一個地配置於前述有機電激發光 被動矩陣元件之前述複數之陽極線之兩端，配置於前述複 數之陽極線之兩端之2個驅動裝置乃以導線連接同步地， 分割前述有機電激發光被動矩陣元件而驅動爲特徵者。 另外，記載於申請專利範圍第5項之發明，在申請專 利範圍第1項至第4項之任一項之有機電激發光被動矩陣元 件之驅動裝置中，前述有機電激發光被動矩陣元件乃畫素 數爲240RGB畫素以上X320行以上者。 [發明之效果] 如根據本發明，可提供由具備2個列驅動器於陰極線 -9- 200910297 之雨端情況，實現消耗電力的降低及亮度不勻之抑制，由 將行驅動器與2個列驅動器封裝於單一之1C情況，謀求低 成本化之有機電激發光被動矩陣元件之驅動裝置。 【實施方式】 [爲了實施發明之最佳形態] 以下，參照圖面而詳細說明本發明之實施型態。 (實施型態1) 圖5係表示有關本發明之第1實施型態之有機EL被動 矩陣元件之驅動裝置。驅動裝置5 0 0係爲驅動m列X η行之 有機EL被動矩陣元件510之裝置，其中，具備行驅動器 501，和第一之列驅動器502，和第二之列驅動器503，和 記憶體5 04，和電源/控制信號輸入505。而有機EL被動矩 陣元件510之各有機EL元件的陽極側乃與行驅動器501之 各輸出連接，陰極側乃對各行，連接於列驅動器5〇2及503 之各輸入。 電源/控制信號輸入505係接受來自外部之電力及控制 信號，將電力及控制信號供給至行驅動器5 〇 1，和第一之 列驅動器5 02，和第二之列驅動器503 ’和記憶體504。此 係例如爲行驅動器5 0 1之電源電壓Vs ’對於記憶體5 (Μ寫 入顯示資料等。 有關本實施型態之驅動裝置係其特徵乃行驅動器5 〇 1 與列驅動器5 0 2及5 0 3，則猶如圖5所示之配置而封裝於單 一之1C情況。行驅動器501係接近於1C之周圍之一邊而 -10 - 200910297 配置，列驅動器5 0 2及5 0 3乃分別接近鄰接於配置行驅動器 501之一邊的邊而配置。將列驅動器從1個增加至2個時， 成爲3個驅動器要素，成本則增加，但是將3個驅動器要素 封裝爲1個之情況，可謀求低成本化。 圖6係表示驅動裝置之變形形態。驅動裝置6 0 0係除了 列驅動器以外，具備與驅動裝置500同一之構成要素。針 對在驅動裝置600，列驅動器602及603乃呈彎曲，各別接 近行驅動器501，和鄰接於配置行驅動器501之一邊的邊而 配置。而驅動裝置600之構成係將驅動裝置作爲封裝化之 1C的大小限制於鄰接於配置行驅動器501之一邊的邊之方 向時較爲有用。 如以上說明，有關本第一實施型態之驅動裝置係由具 備2個之列驅動器於陰極線之兩端情況，實現消耗電力的 降低及亮度不勻之抑制，由將行驅動器與2個列驅動器封 裝於單一之IC情況，謀求低成本化。 (實施型態2) 圖7係表示有關本發明之第2實施型態之有機EL被動 矩陣元件之驅動裝置。驅動裝置7〇〇係具備有關第1實施型 態之第1驅動裝置7 1 0，和有關第1實施型態之第2驅動裝置 720，和連接第一之驅動裝置710與第二之驅動裝置720之 導線730。而第一之驅動裝置710及第二之驅動裝置720係 配置於有機EL被動矩陣元件740之陽極線之兩端，經由 導線73 0以同步地’分割有機EL被動矩陣元件740爲2個 -11 - 200910297 如2.8英吋QVGA(240RGB畫素χ320行）之大型有機EL 被動矩陣元件之情況，在以往之裝置中，掃描周期則成爲 I/3 20，有必要增加電流，但在本發明中，由分割成2個而 驅動之情況’可將掃描周期，從1 /3 20提升至1/160。當如 此做爲時，將有機EL元件之驅動電流作爲一半而將消耗 電力降低至以往之1 / 2以下同時，可確保必要之亮度。並 加上，可降低陽極阻抗的電壓降及消耗電力。 並且，陽極阻抗係爲透明之電極，而材料係使用IΖ Ο 等，但在2.8英寸之情況，陽極線的長度爲6〇111111，12〇的 厚度爲440nm時，成爲12ΚΩ前後，當流動電流150μΑ時 ，經由陽極阻抗之電壓降乂2係亦成爲1.8ν(12ΚΩχ0.15ηιΑ) 。而如做分割則爲其一半。 2個1C係爲了將所分割之範圍做爲1個之畫面，而以 導線730進行連接，取得列（掃描）方向的同步同時分割上 下，由各自之行（畫素）資料而顯示有機EL被動矩陣元件 〇 如以上說明，有關本實施型態之驅動裝置係由將具備 2個列驅動器之驅動裝置，配置於有機E L被動矩陣元件 之陽極線之兩端而分割進行驅動之情況，可實現更降低消 耗電力者。 【圖式簡單說明】 [圖1]係爲表示以往之有機EL被動矩陣元件之驅動裝 -12- 200910297 置的圖。 [圖2]係爲表示圖1之驅動裝置之電壓降與行方向的關 係圖。 [圖3]係爲表示以往之其他有機El被動矩陣元件之驅 動裝置的圖。 [圖4]係爲表75圖3之驅動裝置之電壓降與行方向的關 係圖。 [圖5]係爲表示有關本發明之第1實施形態之有機EL 被動矩陣元件之驅動裝置的圖。 [圖6]係爲表示第1實施形態之變形形態的圖。 [圖7]係爲表示有關本發明之第2實施形態之有機EL 被動矩陣元件之驅動裝置的圖。 【主要元件符號說明】 100 :驅動裝置 1 0 1 :列驅動器 102 :行驅動器 110，3 10 :有機EL被動矩陣元件 3 0 0 :驅動裝置 3 0 1 :列驅動器 302，3 03 :驅動裝置 5 0 1，7 1 1，7 2 1 :列驅動器 502，503，602 > 603，712，713，722，72 3 ：行驅動器 504，7 14，724 :記憶體 -13- 200910297 5 0 5， 5 10, 700 ： 73 0 ： 715，72 5 :電源/控制信號輸入 740 :有機EL被動矩陣元件 2分割驅動用之驅動裝置 導線 -14-
