Description

利用重疊式多重掃描驅動之色序法顯示裝置及相關方法
本發明係關於一種重疊式多重掃描驅動之色序法顯示方法以及相關裝置，尤指一種利用插黑技術來消除面板中畫素所殘留之前一顏色的影像資料的重疊式多重掃描驅動之色序法顯示方法以及相關裝置。
顯示器中顯示色彩的混色(color mixture)法，可以分為時間和空間兩種。時間性混色法係利用不同的時間軸讓RGB的光源通過來進行混色，例如繼續加法混色法(color sequential method)，係利用人眼之視覺暫留(photogene)現象，讓人類的視覺系統感知混色的效果。空間性混色，例如同時加法混色法(color concurrent method)、並置加法混色法(strip alignment method)。請參考第1圖，第1圖係為並置加法混色法，同時加法混色法，以及繼續加法混色法之示意圖。目前以採用彩色濾光片之並置加法混色法，為顯示器主要的混色方法，以薄膜電晶體液晶顯示器(Thin Field Transistor Liquid Crystal Display,TFT-LCD)為例，每一顯示畫素均由彩色濾光片上所分佈之紅、綠、藍(RGB)三個子畫素所構成，這些子畫素小於人眼可分辨的視角範圍，讓人類的視覺系統感知混色的效果。但是時間性混色的繼續加法混色法，漸漸有後來居上的趨勢。與並置加法混色法比較起來，繼續加法混色法具有：1.高解析度；2.驅動IC數目可以減少；3.可以進行彩色平衡調整；4.少了彩色濾光片，使液晶穴之構成單純化，並可以減少空間等等的優點，採用繼續加法混色法之顯示器稱為色序法顯示器(Field Sequential Display,FSD)。
請參考第2圖。第2圖係為傳統之FSD 10的系統架構方塊圖。第2圖中包含一視訊源12，一色序法控制器14，一記憶體16，一顯示面板模組18，以及一背光模組20。如第2圖所示，並列之視訊信號RGB以及控制信號由視訊源12輸入色序法控制器14。色序法控制器14包含輸出入暫存器(buffer)F1以及F2，一資料流轉換器141，以及一記憶體控制單元143。輸出入暫存器F1係用來接收由視訊源12所傳來之信號，如前述之並列之視訊信號RGB以及控制信號，資料流轉換器141係用來將並列之視訊信號RGB轉換為序列之視訊信號RGB，輸出入暫存器F2係用來輸出由資料流轉換器141所傳來之序列之視訊信號RGB，而記憶體控制單元143係用來傳輸或接收記憶體16所傳來或接收之信號。接著輸出入暫存器F2輸出由資料流轉換器141所傳來之序列之視訊信號RGB至顯示面板模組18，並輸出色序法(Color Sequential Method)驅動信號至背光模組20。當輸出入暫存器F2輸出色序法驅動信號至背光模組20時，色序法控制器14會同步控制背光模組20，使其配合所欲顯示之不同的RGB信號，點亮相對應背光光源中的發光二極體。
第3圖係為傳統FSD背光模組20之驅動波型示意圖。由第3圖中可看出，當一影像畫面之紅色影像資料完成寫入後，背光模組20中之複數個紅色發光二極體配合著被點亮，接著該影像畫面之綠色影像資料完成寫入後，背光模組20中之複數個綠色發光二極體配合著被點亮，最後當該影像畫面之藍色影像資料完成寫入後，背光模組20中之複數個藍色發光二極體即配合著被點亮。如第3圖所示，背光模組20中一種顏色之發光二極體之開啟係於該種顏色之影像資料完成寫入後進行，因為若該種顏色之影像資料尚未寫入時，畫素的液晶中會殘留有前一種顏色的影像資料，此時若將該種顏色之發光二極體開啟，會產生干擾。然而，因為一畫面之掃描線係由第1條掃描到最後一條，亦即前幾條掃描線和最後幾條掃描線的畫素開啟時間會有時間差，導致前幾條掃描線和最後幾條掃描線的一種顏色的影像資料的寫入完成時間產生時間差；而如前所述，在所有的該種顏色之影像資料全部寫入後，背光模組20中之該種顏色之發光二極體才能被開啟，因此在此種情形下，造成後面幾條掃描線之該種顏色之發光二極體之開啟時間會變得太短而導致液晶的反應時間不足，無法達到所設定之穿透亮度響應，而產生畫面的上下區域色不均的現象。且因色序法之寫入頻率提升，會使得液晶充電時間不足，造成畫面品質不佳，如第4圖所示。第4圖中，當一畫面中不同顏色的場(field)在反轉時，因各顏色的場的充電時間不足，容易造成畫面的對比不足。若在一畫面(frame)反轉時，因為只有某一顏色的場有充電不足的狀況產生，因此會造成液晶無法關閉該顏色的場的光，如第5圖所示，使得畫面產生色偏的現象。有時再加上考慮液晶的充電時間不足的問題，會將發光二極體的亮燈時間進一步縮短，造成畫面的亮度降低，或者需加入更多顆發光二極體以使得畫面回復原來的亮度。因此，要如何針對這些問題提出適當的解決辦法，實為當前色序法顯示器的設計中一項重要的課題。
本發明之一實施例係揭露一種利用重疊式多重掃描驅動之色序法顯示裝置，包含一薄膜電晶體液晶顯示器面板模組，一背光模組，以及一色序法控制器。該薄膜電晶體液晶顯示器面板模組包含複數個以陣列方式排列之畫素，每一畫素包含一畫素控制開關以及一插黑控制開關。該畫素控制開關包含一閘極及一源極。該插黑控制開關包含一閘極。該背光模組包含複數個紅色發光二極體、複數個綠色發光二極體、及複數個藍色發光二極體。該色序法控制器，包含一時序控制單元，一輸出入暫存器，及一背光模組控制單元。該時序控制單元經由一閘極信號線電連接於該畫素控制開關之閘極，及經由一插黑閘極信號線電連接於該插黑控制開關之閘極，用來控制該畫素控制開關及該插黑控制開關之開啟及關閉。該輸出入暫存器經由一資料信號線電連接於該畫素控制開關之源極，用來對該畫素給予資料信號。該背光模組控制單元電連接於該複數個紅色發光二極體、該複數個綠色發光二極體、及該複數個藍色發光二極體，用來控制該複數個紅色發光二極體、該複數個綠色發光二極體、及該複數個藍色發光二極體之開啟及關閉。
本發明之另一實施例係另揭露一種重疊式多重掃描驅動之色序法顯示方法，包含：開啟一背光模組之複數個區塊中之一第一區塊之一種顏色的發光二極體；當該第一區塊之該種顏色的發光二極體開啟時，將該種顏色的影像資料寫入該第一區塊之畫素；當該種顏色的影像資料完成寫入該第一區塊之畫素之儲存電容之後，開啟該背光模組之與該第一區塊相鄰之一第二區塊之該種顏色的發光二極體；當該第二區塊之該種顏色的發光二極體開啟時，將該種顏色的影像資料寫入該第二區塊之畫素；當該種顏色的影像資料完成寫入該第一區塊之畫素之液晶電容之後，將一插黑的電壓準位寫入該第一區塊之畫素；以及當該插黑的電壓準位完成寫入該第一區塊之畫素之後，關閉該第一區塊之該種顏色的發光二極體。
針對前述之先前技術的缺點，本發明提出一透過插黑技術，在色序法顯示面板模組中的每個畫素中加入一顆插黑控制開關，便可以消除面板中畫素所殘留之前一顏色的影像資料，再加上將一背光模組上之發光二極體，分成複數個區塊重疊式地點亮，延長發光二極體的開啟時間，便可以解決因色序法之寫入頻率提升所造成之發光二極體的亮燈時間縮短使得液晶充電時間不足的問題。
在說明書及後續的申請專利範圍當中使用了某些詞彙來指稱特定的元件。所屬領域中具有通常知識者應可理解，製造商可能會用不同的名詞來稱呼同樣的元件。本說明書及後續的申請專利範圍並不以名稱的差異來作為區別元件的方式，而是以元件在功能上的差異來作為區別的基準。在通篇說明書及後續的請求項當中所提及的「包含」係為一開放式的用語，故應解釋成「包含但不限定於」。此外，「電性連接」一詞在此係包含任何直接及間接的電氣連接手段。因此，若文中描述一第一裝置電性連接於一第二裝置，則代表該第一裝置可直接連接於該第二裝置，或透過其他裝置或連接手段間接地連接至該第二裝置。
請參考第6圖以及第7圖，第6圖係為本發明之一實施例之重疊式多重掃描驅動之色序法顯示裝置(FSD)600的系統結構方塊圖，而第7圖係為本發明之重疊式多重掃描色序法顯示面板模組618中一畫素700的結構示意圖。第6圖中包含一視訊源612，一色序法控制器614，一記憶體616，一顯示面板模組618，以及一背光模組620。如第6圖所示，並列之視訊信號RGB以及控制信號由視訊源612輸入色序法控制器614。色序法控制器614包含輸出入暫存器(buffer)F1以及F2，一資料流轉換器641，以及一記憶體控制單元643。輸出入暫存器F1係用來接收由視訊源612所傳來之信號，如前述之並列之視訊信號RGB以及控制信號，資料流轉換器641係用來將並列之視訊信號RGB轉換為序列之視訊信號RGB，輸出入暫存器F2係用來輸出由資料流轉換器641所傳來之序列之視訊信號RGB，而記憶體控制單元643係用來傳輸或接收記憶體616所傳來或接收之信號。顯示面板模組618包含m*n個以陣列方式排列之畫素，每一畫素均與畫素700結構相同，其中m和n均為一正整數。背光模組620包含複數個紅色發光二極體、複數個綠色發光二極體、及複數個藍色發光二極體。色序法控制器614另包含一時序控制單元623以及一背光模組控制單元626。背光模組控制單元626係電連接於背光模組620的複數個紅色發光二極體、複數個綠色發光二極體、及複數個藍色發光二極體，用來控制複數個紅色發光二極體、複數個綠色發光二極體、及複數個藍色發光二極體之開啟及關閉。輸出入暫存器F2輸出由資料流轉換器641所傳來之序列之視訊信號RGB至顯示面板模組618，並輸出色序法驅動信號至背光模組620。當輸出入暫存器F2輸出色序法驅動信號至背光模組620時，色序法控制器614中的背光模組控制單元626會同步控制背光模組620，使其配合所欲顯示之不同的RGB信號，點亮背光光源中相對應的顏色的發光二極體。
第7圖係為本發明之重疊式多重掃描色序法顯示面板模組618中之一畫素700的結構示意圖。第7圖中之畫素700包含一畫素控制開關701，一插黑控制開關703，一液晶電容707及一儲存電容705。畫素控制開關701包含一閘極、一汲極及一源極，時序控制單元623經由一閘極信號線電連接於畫素控制開關701之閘極，及經由一插黑閘極信號線電連接於插黑控制開關703之閘極，控制畫素控制開關701及插黑控制開關703之開啟及關閉。輸出入暫存器F2經由一資料信號線電連接於畫素控制開關701之源極，用來給予畫素資料信號，亦即輸出入暫存器F2輸出由資料流轉換器641所傳來之序列之視訊信號RGB至顯示面板模組618即經由資料信號線輸入視訊信號RGB至每一畫素控制開關之源極。畫素控制開關701及插黑控制開關703另各包含一汲極，電連接於畫素700之液晶電容707及儲存電容705之一端點，液晶電容707及儲存電容705之另一端點係電連接於共同電壓Vcom端點。
至於本發明之重疊式多重掃描驅動之色序法顯示裝置600中的顯示面板模組618，本發明在此揭露一以點反轉(dot inversion)的方式排列畫素之重疊式多重掃描色序法顯示面板模組的實施例，請參考第8圖以及第9圖。第8圖係為本發明之一實施例之點反轉式的重疊式多重掃描色序法之顯示面板模組800之結構示意圖，而第9圖則為顯示面板802之走線示意圖。第8圖中之顯示面板模組800包含一顯示面板802，一插黑閘極IC 806，一閘極IC 804，及源極IC 808。源極IC 808係位於顯示面板802的下方，而插黑閘極IC 806和閘極IC 804係分別位於顯示面板802的兩側。而第9圖則為顯示面板802之走線示意圖，從第9圖中可看出，顯示面板802中以陣列方式排列之m*n個畫素係以點反轉(每相鄰兩畫素之極性相反)之方式排列，此排列方式可降低閃爍(flicker)的現象的產生。而每一個畫素均包含有一畫素控制開關以及一插黑控制開關。顯示面板802中一第p條閘極信號線係電連接於一第(2p-1)列以及一第2p列畫素之畫素控制開關的閘極，例如第1條閘極信號線係電連接於第1列與第2列畫素的畫素控制開關的閘極，第2條閘極信號線係電連接於第3列與第4列畫素的畫素控制開關的閘極。一第q條插黑閘極信號線係電連接於一第(2q-1)列以及一第(2q-2)列畫素之插黑控制開關的閘極，例如第1條插黑閘極信號線係電連接於第1列畫素的插黑控制開關的閘極，第2條插黑閘極信號線係電連接於第2列與第3列畫素的插黑控制開關的閘極。一第(2r-1)行之奇數列畫素之畫素控制開關的源極係電連接於一第(4r-3)條資料信號線，例如第1行之奇數列畫素之畫素控制開關的源極係電連接於第1條資料信號線，第3行之奇數列畫素之畫素控制開關的源極係電連接於第5條資料信號線。一第(2r-1)行之偶數列畫素之畫素控制開關的源極係電連接於一第(4r-2)條資料信號線，例如第1行之偶數列畫素之畫素控制開關的源極係電連接於第2條資料信號線，第3行之偶數列畫素之畫素控制開關的源極係電連接於第6條資料信號線。一第2r行之奇數列畫素之畫素控制開關的源極係電連接於一第4r條資料信號線，例如第2行之奇數列畫素之畫素控制開關的源極係電連接於第4條資料信號線，第4行之奇數列畫素之畫素控制開關的源極係電連接於第8條資料信號線。以及一第2r行之偶數列畫素之畫素控制開關的源極係電連接於一第(4r-1)條資料信號線，例如第2行之偶數列畫素之畫素控制開關的源極係電連接於第3條資料信號線，第4行之偶數列畫素之畫素控制開關的源極係電連接於第7條資料信號線。其中m、n、p、q、r均為一正整數。而所有插黑控制開關的源極均電連接於一條插黑資料信號線，用來接收一插黑的電壓準位。插黑閘極信號線係電連接於插黑閘極IC 806，閘極信號線係電連接於閘極IC 804，及資料信號線係電連接於源極IC 808。
請參看第10圖和第11圖，第10圖係為根據本發明之一實施例之重疊式多重掃描驅動之色序法顯示方法的步驟流程圖，包含：步驟100：開啟背光模組620之複數個區塊中之一第一區塊之一種顏色的發光二極體；
步驟102：當第一區塊之該種顏色的發光二極體開啟時，將該種顏色的影像資料寫入第一區塊之畫素；
步驟104：當該種顏色的影像資料完成寫入第一區塊之畫素之儲存電容之後，開啟背光模組620之與第一區塊相鄰之一第二區塊之該種顏色的發光二極體；
步驟106：當第二區塊之該種顏色的發光二極體開啟時，將該種顏色的影像資料寫入第二區塊之畫素；
步驟108：當該種顏色的影像資料完成寫入第一區塊之畫素之液晶電容之後，將一插黑的電壓準位寫入第一區塊之畫素；
步驟110：當插黑的電壓準位完成寫入第一區塊之畫素之後，關閉第一區塊之該種顏色的發光二極體。
第11圖係為根據本發明之重疊式多重掃描驅動之色序法顯示方法的驅動原理。從第11圖中可看出，背光模組620的發光二極體被分為4個區塊，例如第一區塊、第二區塊、第三區塊及第四區塊。第一區塊的位置係相對於顯示面板模組800中第1條至第i條掃描線的位置，第二區塊的位置係相對於顯示面板模組800中第i+1條至第2i條掃描線的位置，第三區塊的位置係相對於顯示面板模組800中第2i+1條至第3i條掃描線的位置，及第四區塊的位置係相對於顯示面板模組800中第3i+1條至第4i條掃描線的位置，其中i為一正整數，m=4*i。每個區塊中的同一種顏色的發光二極體每間隔一段時間依序重疊式地被開啟。首先，開啟背光模組620之四個區塊中之第一區塊之紅色發光二極體(步驟100)，並且當第一區塊之紅色的發光二極體開啟時，將紅色的影像資料寫入第一區塊之畫素(步驟102)。接著當紅色的影像資料完成寫入第一區塊之畫素之儲存電容之後，開啟背光模組620之第二區塊之紅色的發光二極體(步驟104)，並且當第二區塊之紅色的發光二極體開啟時，將紅色的影像資料寫入第二區塊之畫素(步驟106)。接著當紅色的影像資料完成寫入第一區塊之畫素之液晶電容之後，將一插黑的電壓準位寫入第一區塊之畫素(步驟108)，接著當插黑的電壓準位完成寫入第一區塊之畫素之後，關閉第一區塊之紅色的發光二極體(步驟110)。同樣地，當紅色的影像資料完成寫入第二區塊之畫素之儲存電容之後，開啟背光模組620之第三區塊之紅色的發光二極體，並且當第三區塊之紅色的發光二極體開啟時，將紅色的影像資料寫入第三區塊之畫素。接著同樣地，當紅色的影像資料完成寫入第二區塊之畫素之液晶電容之後，將插黑的電壓準位寫入第二區塊之畫素，並且當插黑的電壓準位完成寫入第二區塊之畫素之後，關閉第二區塊之紅色的發光二極體。依此類推，完成寫入四個區塊之紅色、藍色、及綠色發光二極體的影像資料以及插黑電壓準位，如第11圖所示。請注意：開啟第二區塊之紅色的發光二極體係於紅色的影像資料尚未完成寫入第一區塊之畫素之液晶電容時即開始執行，同樣地，開啟第三區塊之紅色的發光二極體係於紅色的影像資料尚未完成寫入第二區塊之畫素之液晶電容時即開始執行，以此方式依序寫入四個區塊之紅色、藍色、及綠色發光二極體的影像資料。
由於在本發明之重疊式多重掃描驅動之色序法顯示方法中，液晶反應時間與發光二極體的亮燈時間係每一條掃描線均相同，因此可有效地解決液晶反應時間不足所造成的色不均與色偏的問題。並且透過使用多重掃描的驅動原理，提升充電時間，因此不只可實現如第11圖中之每一幀畫面可包含紅藍綠三種顏色之發光二極體各開啟一次的驅動方式(3 fields per frame)，更可以實現每一幀畫面包含紅藍綠三種顏色之發光二極體開啟不只一次，例如4 fields per frame，如第12圖所示。利用每一幀畫面中紅藍綠三種顏色之發光二極體共可開啟4次的方法，彌補某一顏色在該幀畫面中顯示不足的缺點，例如以RGBG或RGBR→GBRG→BRGB的方式，進一步減少色分離現象的產生。除此之外，因為本發明在每個畫素中所插黑之電壓準位均相同，因此在每次寫入影像資料時，每個液晶皆從插黑之黑階開始達到所需之灰階，因此只需調整Gamma電壓便可提升液晶之反應速度，請參考第13圖。第13圖係為根據本發明之重疊式多重掃描驅動之色序法顯示方法之液晶轉態圖。在第13圖中，每個液晶皆從插黑之黑階開始達到所需之灰階，因此只需搭配新的驅動電壓便可提升液晶的反應速度，而不需透過查表等方式，尋求每一畫素所相對應之一新的驅動電壓。
總而言之，本發明提供利用插黑技術來消除面板中畫素所殘留之前一顏色的影像資料的重疊式多重掃描驅動之色序法顯示方法以及相關裝置，不但可解決先前技術中色不均及色偏的問題，更可進一步改善色分離的現象，簡化尋求Gamma驅動電壓的步驟，實為一一舉數得之方法。
