Description

電致發光顯示器及其驅動方法
本發明是關於一種電致發光顯示器及其驅動方法。
用以呈現畫面的顯示器可包含在一矩陣內排列成列與行的多個像素。這些像素的每一列透過一閘極線(或掃描線)而耦接至閘極驅動器，而這些像素的每一行則透過一資料線(或源極線)而耦接至資料驅動器。所述的閘極驅動器透過其個別的閘極線來選擇多個目標像素的相應列。所述的資料驅動器則透過其個別的資料線將資料提供至所選列中多個像素的相應行。
本發明的實施例提供一種電致發光(EL)顯示器。該EL顯示器包含在排列於N列與M行的矩陣中的複數個像素單元，N和M為自然數；複數個掃描線用以選擇目標像素單元；複數個資料線用以提供資料給目標像素單元；以及一控制線用以控制分別耦接至第(2k-1)條及第2k條掃描線之緊鄰列的像素單元，k為介於1至N/2的自然數。 在一實施例中，該控制線平行於該掃描線而延伸。 在另一實施例中，該些像素單元中的一第一像素單元包含一第一EL裝置及用以控制該第一EL裝置的一第一控制器。此外，該些像素單元中的一第二像素單元包含一第二EL裝置及用以控制該第二EL裝置的一第二控制器。 於又一實施例中，該第一EL裝置係設於該第二控制器上方，且該第二EL裝置係設於該第一控制器上方。 在又另一實施例中，該第一EL裝置包含一電晶體，且該電晶體之一閘極係用以接收透過該控制線所傳送的一控制信號。此外，該第二EL裝置包含一電晶體，及此電晶體的一閘極係用以接收透過該控制線所傳送的一控制信號。 本發明的某些實施例提供一種驅動電致發光(EL)顯示器的方法，該EL顯示器包含排列於一矩陣中的複數個像素單元。該方法包含透過N條掃描線來掃描該矩陣以選擇目標像素單元，N為自然數；透過M條資料線將一影像資料提供給該目標像素單元，M為自然數；以及透過一控制線將一控制信號提供給該目標像素單元，該控制線控制該矩陣中分別耦接至第(2k-1)條及第2k條掃描線之緊鄰列的像素單元，k為介於1至N/2的自然數。 在一實施例中，該方法還包含根據該影像資料，分別由一第一像素單元的一第一EL裝置及一第二像素單元的一第二EL裝置發出光線。 在另一實施例中，該第一EL裝置係設於該第二像素單元之一第二控制器上方，且該第二EL裝置係設於該第一像素單元的一第一控制器上方。
以下揭示內容提供了多種實施方式或例示，其能用以實現本揭示內容的不同特徵。下文所述之元件與配置的具體例子係用以簡化本揭示內容。當可想見，這些敘述僅為例示，其本意並非用於限制本揭示內容。舉例來說，在下文的描述中，將一第一特徵形成於一第二特徵上或之上，可能包含某些實施例其中所述的第一與第二特徵彼此直接接觸；且也可能包含某些實施例其中還有而外的元件形成於上述第一與第二特徵之間，而使得第一與第二特徵可能沒有直接接觸。此外，本揭示內容可能會在多個實施例中重複使用元件符號和/或標號。此種重複使用乃是基於簡潔與清楚的目的，且其本身不代表所討論的不同實施例和/或組態之間的關係。 此外，當可理解，若將一部件描述為與另一部件「連接(connected to)」或「耦接(耦接至)」，則兩者可直接連接或耦接，或兩者間可能出現其他中間(intervening)部件。 圖1為根據某些實施例之電致發光(EL)顯示器10的示意圖。 參照圖1，該EL顯示器10包含一主動區域12，其可包含一像素單元陣列，舉例來說，所述像素單元陣列可透過複數個像素單元排列於一N×M矩陣中，N與M分別是一自然數。為求簡潔，圖中僅標記例示性像素單元P_1M、P_2M、P_1M-1與P_2M-1。為了驅動像素單元，排列於列方向中的掃描線S_1至S_N係用以掃描像素單元的一或多相應列，而排列於行方向中的資料線D_1至D_M係用以提供影像資料至所述掃描線所選擇的目標像素單元。在一實施例中，主動區域12中的每一像素單元包含三個子像素單元(圖中未繪示)，其可用以顯示紅色(R)、綠色(G)及藍色(B)。此外，這三種子像素可排列於列的方向中。因此，資料線的數目為3×M。在另一實施例中，例如，子像素渲染(sub-pixel rendering，SPR)感應器，子像素單元的數目不限於三。 除了掃描線S_1至S_N以及資料線D_1至D_M之外，所述EL顯示器10還包含控制線E_1至E_N/2，其係用以控制像素單元的發光狀態。在本實施例中，控制線E_1至E_N/2於列方向中延伸，且平均排置於N列的像素單元中。如此一來，控制線E_1至E_N/2中的每一條可用以控制兩列緊鄰的像素單元。例如，第一控制線E_1可控制複數個像素單元中分別耦接至掃描線S_1與S_2的第一與第二列像素單元，而第二控制線E_2則可控制複數個像素單元中分別耦接至掃描線S_3與S_4的第三與第四列像素單元，依此類推。因此，控制線E_k可控制複數個像素單元中分別耦接至掃描線S_2k-1與S_2k的緊鄰之像素單元列，其中k為從1到N/2的自然數。如此一來，可透過控制線E_k來傳送一單一控制信號E，以控制不同列上之像素單元的發光狀態。此一驅動機制有利於將一像素單元中之控制器以及受其控制的EL裝置製備為堆疊形式。因此，所述EL顯示器10可有效地享有一有效率的面積成本(area cost)及一有彈性的佈局設計。 圖2為根據某些實施例，圖1所示EL顯示器10中的控制器CTR_A至CTR_F與其個別的EL裝置EL_A至EL_F的概要佈局。 參照圖2，可在一半導體基材(圖中未繪示)上形成所述的EL裝置EL_A至EL_F，並可在半導體基材與EL裝置EL_A至EL_F之間形成用以控制EL裝置EL_A至EL_F的控制器CTR_A至CTR_F。上述控制器CTR_A與EL裝置EL_A共同形成一像素單元，控制器CTR_B與EL裝置EL_B共同形成另一像素單元，依此類推。為求簡潔，圖中僅繪示六個此種像素單元。所述EL裝置EL_A至EL_F中每一個EL裝置包含，例如，一電流驅動部件，其可以是一有機發光二極體(organic light emitting diode，OLED)、一微LED或一量子點LED(quantum dot LED，QLED)。此外，所述EL裝置EL_A至EL_F中的每一者可用以顯示紅色(R)、綠色(G)或藍色(B)。 所述控制器CTR_A、CTR_C與CTR_E排列在標示為R_n的第n列中，而所述控制器CTR_B、CTR_D與CTR_F標示為R_n+1的第n+1列中。此外，所述控制器CTR_A與CTR_B排列在標示為C_m-1的第(m-1)行中，所述控制器CTR_C與CTR_D排列在標示為C_m的第m行中，而所述控制器CTR_E與CTR_F排列在標示為C_m+1的第(m+1)行中。提供用於R_n列與R_n+1列之像素單元的控制線E_k。 此外，所述EL裝置EL_B、EL_D與EL_F排列於第n列R_n中，而所述EL裝置EL_A、EL_C與EL_E排列於第n+1列R_n+1中。此外，所述EL裝置EL_B與EL_A排列於第(m-1)行C_m-1中，所述EL裝置EL_D與EL_C排列於第m行C_m中，且所述EL裝置EL_F與EL_E排列於第(m+1)行C_m+1中。如此一來，所述EL裝置EL_B、EL_D與EL_F分別堆疊於上述控制器CTR_A、CTR_C與CTR_E上，而所述EL裝置EL_A、EL_C與EL_E分別堆疊於上述控制器CTR_B、CTR_D與CTR_F中。在此種堆疊結構中，透過控制線E_k與導電通道(圖中未繪示)將一控制信號傳送至EL裝置EL_A至EL_F。 圖3為根據某些實施例，圖1所示EL顯示器10中例示性像素單元的概要透視圖。 參照圖3，控制器CTR_1M與相應的EL裝置EL_1M形成了圖1所示之例示性像素單元P_1M，而控制器CTR_2M與相應的EL裝置EL_2M形成了圖1所示之例示性像素單元P_2M。此外，所述的EL裝置EL_1M與EL_2M分別堆疊於控制器CTR_2M與CTR_1M之上。 再者，控制器CTR_1M-1與相應的EL裝置EL_1M-1形成了圖1所示的例示性像素單元P_1M-1，而控制器CTR_2M-1與相應的EL裝置EL_2M-1形成了圖1所示的例示性像素單元P_2M-1。此外，所述EL裝置EL_1M-1與EL_2M-1分別堆疊於控制器CTR_2M-1與CTR_1M-1上。 所述控制器CTR_1M用以透過掃描線S_1接收掃描信號，並透過資料線D_M接收影像資料。同理，所述控制器CTR_2M用以透過掃描線S_2接收掃描信號，並透過資料線D_M接收影像資料。同理，所述控制器CTR_1M-1用以透過掃描線S_1接收掃描信號，並透過資料線D_M-1接收影像資料。此外，所述控制器CTR_2M-1透過掃描線S_2用以接收掃描信號，並透過資料線D_M-1接收影像資料。控制線E_1以及掃描線S_1與S_2在和所述控制器CTR_1M、CTR_2M、CTR_1M-1與CTR_2M-1相關的導電層中彼此平行延伸。資料線D_M與D_M-1實質上與上述控制線E_1以及掃描線S_1與S_2垂直，並在和所述EL裝置EL_1M、EL_2M、EL_1M-1與EL_2M-1相關的導電層中彼此平行延伸。 圖4A為根據一實施例，圖1所示EL顯示器10中之例示性像素單元P_1M與P_2M的圖式。 參照圖4A，為了便於說明，在此將像素單元P_1M稱為第一像素單元，其包含一第一控制器CTR_1M及一第一EL裝置EL_1M。此外，所述第一EL裝置EL_1M還包含一第一發光二極體41以及作為一第一開關的一電晶體SW1。在本實施例中，所述電晶體SW1包含一p-型電晶體，其可以是p-型金屬氧化物半導體(p-type metal-oxide-semiconductor, PMOS)電晶體或p-型薄膜電晶體(thin film transistor, TFT)。此外，所述電晶體SW1的閘極係用以接收透過第一控制線E_1所傳來的第一控制信號e_1。所述電晶體SW1的源極耦接至上述第一控制器CTR_1M。所述電晶體SW1的汲極耦接至第一發光二極體41的陽極。除此之外，所述第一發光二極體41的陰極耦接至電源VSS。在一實施例中，VSS的電壓位準接近接地電壓位準或為負電壓位準，如負5伏特(-5V)。 在操作上，選擇上述第一像素單元(即像素單元P_1M)作為目標像素單元時，會將第一影像資料儲存在第一控制器CTR_1M中。在發光期間，第一控制信號e_1會開啟電晶體SW1，使得一電流能夠流經第一發光二極體41。所述電流的強度係由上述第一影像資料所決定。 同理，為了便於說明，在此將像素單元P_2M稱為第二像素單元，其包含第二控制器CTR_2M與第二EL裝置EL_2M。此外，所述第二EL裝置EL_2M還包含一第二發光二極體42與作為第二開關的一電晶體SW2。在本實施例中，所述電晶體SW2包含一p-型電晶體，其可以是PMOS電晶體或p-型TFT。此外，所述電晶體SW2的閘極耦接至上述電晶體SW1的閘極，且用以接收透過第一控制線E_1所傳來的第一控制信號e_1。所述電晶體SW2的源極耦接至上述第二控制器CTR_2M。所述電晶體SW2的汲極耦接至第二發光二極體42的陽極。除此之外，所述第二發光二極體42的陰極耦接至電源VSS。 在操作上，當選擇上述第二像素單元(即像素單元P_2M)作為目標像心單元時，會將第二影像資料儲存在第二控制器CTR_2M中。在發光期間，上述第一控制信號e_1會開電晶體SW2，使得一電流能夠流經上述第二發光二極體42。所述電流的強度由第二影像資料所決定。 圖4B為根據一實施例，圖1所示之EL顯示器10中例示性像素單元P_1M的電路圖。 參照圖4B，所述的第一像素單元P_1M的第一控制器CTR_1M包含一第一電晶體T1、一第二電晶體T2與一電容器C。又，圖4A中所述的第二像素單元P_2M的第二控制器CTR_2M亦包含如圖4B所示的一第一電晶體T1、一第二電晶體T2與一電容器C。為求簡潔，僅範例說明該第一控制器CTR_1M，而第二控制器CTR_2M則不另贅述。上述第一電晶體T1與第二電晶體T2分別包含一p-型電晶體，其可以是PMOS電晶體或一p-型TFT。所述第一電晶體T1的閘極接收透過掃描線S_1而傳送的掃描信號s_1。所述第一電晶體T1的源極接收透過資料線D_M而傳送的影像資料d_M。所述第一電晶體T1的汲極耦接至電容器C的一端以及第二電晶體T2的閘極。本發明所述技術領域中具有通常知識者當可理解，電晶體的源極與汲極端可互換，其係取決於施加於該處的電壓位準。又，所述第二電晶體T2的源極耦接至另一電源VDD。在一實施例中，VDD的電壓位準約為5伏特(5V)。所述第二電晶體T2的汲極耦接至電晶體SW1的源極。第二電晶體T2係作為一驅動電晶體，當將其開啟時，會使得一電流由VDD流向第一發光二極體41。此外，電容器C的另一端係耦接至VDD。上述像素單元P_1M的電路結構不限於所繪示的特定實施例。例如，第一控制器CTR_1M可包含更多電晶體或電容器，以執行所欲功能，譬如補償功能以減輕第二電晶體T2中的閾值效應，此種閾值效應會減低EL顯示器10中各像素單元亮度的一致性。 在操作上，當該掃描信號s_1開啟上述第一電晶體T1時，會選擇第一像素單元P_1M作為目標像素單元。其後，將一影像資料d_M儲存於電容器C中。在發光期間，當該電晶體SW被第一控制信號e_1所開啟時，流經第一發光二極體41的電流會使得所述第一發光二極體41發光，而此一光線的強度係由影像資料d_M所決定。 圖5A為根據另一實施例，圖1所示EL顯示器10中例示性像素單元P_1M與P_2M 的圖式。 參照圖5A，所述像素單元P_1M與P_2M的電路結構與上文參照圖4A所述者相似，不同之處在於，例如，以n-型電晶體SW1及SW2取代前述的p-型電晶體。於一實施例中，n-型電晶體可包含n-型金屬氧化物半導體(n-type metal-oxide-semiconductor, NMOS)電晶體或n-型薄膜電晶體(TFT)。 圖5B是根據另一實施例，圖1所示之EL顯示器10中例示性像素單元P_1M的電路圖。 參照圖5B，所述像素單元P_1M的電路結構與上文參照圖4B所述者相似，不同之處在於，例如，以n-型電晶體T1與T2取代前述的p-型電晶體。 圖6為一流程圖，其繪根據某些實施例用以驅動一EL顯示器的方法。 參照圖6，於操作61，提供一電致發光(EL)顯示器。所述的EL顯示器，譬如上文參照圖1所示的EL顯示器10，包含複數個排列於N列與M行的矩陣中的像素單元，其中N與M為自然數。 在操作63，利用N條掃描線來掃描上述矩陣，以選擇一或多個目標像素單元。 在操作65，透過M條資料線將影像資料提供給目標像素單元。 在操作67，透過控制線E_k將控制信號提供給目標像素單元。所述控制線E_k用以控制分別耦接至掃描線S_2k-1及S_2k的緊鄰之像素單元列，其中k為從1到N/2的自然數。 其後，在操作68，上述所選像素單元中的第一像素單元之第一EL裝置與及第二像素單元之第二EL裝置分別根據所述影像資料發出光線。所述第一EL裝置設置於用以控制第二EL裝置之第二像素單元的第二控制器上方，且所述第二EL裝置設置於用以控制第一EL裝置之第一像素單元的第一控制器上方。
