Description
本揭示文件有關一種顯示面板和畫素電路,尤指一種具有串聯電容結構的液晶畫素電路。
扭曲向列型(twisted nematic,簡稱TN)液晶顯示器、面內轉向(in-plane switchin,簡稱IPS)液晶顯示器以及垂直配向(vertical alignment,簡稱VA)液晶顯示器的畫素電路中,儲存電容和液晶電容通常耦接於不同的電極。因此,當資料訊號傳輸至畫素電路內部,且耦接於儲存電容的電極同時提供交流電壓至儲存電容時,耦接於液晶電容的電極能夠提供直流電壓以穩定液晶電容兩端的電壓差。
然而,對於邊緣電場切換(fringe-field switching,簡稱FFS)液晶顯示器的畫素電路而言,儲存電容和液晶電容是耦接於相同的電極。當資料訊號以及交流電壓同時分別傳輸至液晶電容的兩端時,資料訊號和交流電壓會因為電容耦合效應而互相干擾。因此,液晶電容兩端之間的電壓差便無法精確地控制於預期的數值。
本揭示文件提供一種顯示面板。顯示面板包含多個畫素電路,且每個畫素電路包含第一開關、儲存電路、第二開關以及液晶電容。第一開關包含第一端、第二端和控制端,其中第一開關的第一端用於接收資料訊號,第一開關的第二端耦接於第一節點。儲存電路耦接於第一節點,且用於接收共同電壓。第二開關包含第一端、第二端和控制端,其中第二開關的第一端耦接於儲存電路,第二開關的第二端用於接收極性控制訊號。液晶電容耦接於第一節點與儲存電路之間。當第一開關導通時,第二開關會導通,或者當第二開關導通時,第一開關會導通。畫素矩陣包含多列和多行的畫素電路,多列畫素電路的其中一列包含第一畫素電路和第二畫素電路,第一畫素電路和第二畫素電路分別位於多行畫素電路的相鄰兩行,第一畫素電路接收到的第一極性控制訊號以及第二畫素電路接收到的第二極性控制訊號具有彼此相反的電壓極性。
本揭示文件提供一種畫素電路。畫素電路包含第一開關、儲存電路、第二開關以及液晶電容。第一開關包含第一端、第二端和控制端,其中第一開關的第一端用於接收一資料訊號,第一開關的第二端耦接於第一節點。儲存電路耦接於第一節點,且用於接收共同電壓。第二開關包含第一端、第二端和控制端,其中第二開關的第一端耦接於儲存電路,且第二開關的第二端用於接收極性控制訊號。液晶電
容耦接於第一節點和儲存電路之間。當第一開關導通時,第二開關會導通,或者當第二開關導通時,第一開關會導通。

以下將配合相關圖式來說明本揭示文件的實施例。在圖式中,相同的標號表示相同或類似的元件或方法流程。
第1圖為依據本揭示文件一實施例的顯示面板100簡化後的功能方塊圖。顯示面板100包含多個畫素電路110、閘極驅動器120、源極驅動器130、多個閘極驅動線GL-1~GL-n以及多個源極驅動線SL-1~SL-n。多個畫素電路110用於設置成畫素矩陣PA,其中畫素矩陣PA包含多行與多列的畫素電路110。為使圖面簡潔而易於說明,顯示面板100中的其他元件與連接關係並未繪示於第1圖中。
閘極驅動線GL-1~GL-n分別用於對應地提供第一控制訊號Sc1-1~Sc1-n的其中一者至畫素矩陣PA。源極驅動線SL-1~SL-n分別用於對應地提供資料訊號Sda-1~Sda-n的其中一者至畫素矩陣PA。
本案說明書和圖式中使用的元件編號和訊號編號中的索引1~n,只是為了方便指稱個別的元件和訊號,並非有意將前述元件和訊號的數量侷限在特定數目。在本案說明書和圖式中,若使用某一元件編號或訊號編號時沒有指明該元件編號或訊號編號的索引,則代表該元件編號或
訊號編號是指稱所屬元件群組或訊號群組中不特定的任一元件或訊號。例如,元件編號GL-1指稱的對象是閘極訊號線GL-1,而元件編號GL指稱的對象則是閘極訊號線GL-1~GL-n中不特定的任意閘極訊號線GL。又例如,訊號編號Sc1-1指稱的對象是第一控制訊號Sc1-1,而訊號編號Sc1指稱的對象則是第一控制訊號Sc1-1~Sc1-n中不特定的任意第一控制訊號Sc1。
對畫素矩陣PA的任意一列的畫素電路110而言,該任意一列的畫素電路110會相鄰於兩條閘極驅動線GL。於該任意一列的畫素電路110中,耦接於編號為奇數的源極驅動線SL(例如,源極驅動線SL-1和SL-3等等)的部分畫素電路110,會耦接於前述兩條閘極驅動線GL的其中一者。另一方面,耦接於編號為偶數的源極驅動線SL(例如,源極驅動線SL-2和SL-4等等)的另一部分畫素電路110,會耦接於前述兩條閘極驅動線GL的另一者。
以位於閘極驅動線GL-1和GL-2之間的一列畫素電路110為例,耦接於編號為奇數的源極驅動線SL(例如,源極驅動線SL-1和SL-3等等)的部分畫素電路110,會耦接於閘極驅動線GL-1。另一方面,耦接於編號為偶數的源極驅動線SL(例如,源極驅動線SL-2和SL-4等等)的另一部分畫素電路110,會耦接於閘極驅動線GL-2。
另外,以位於閘極驅動線GL-2和GL-3之間的一列畫素電路110為例,耦接於編號為奇數的源極驅動線SL(例如,源極驅動線SL-3和SL-5等等)的部分畫素電路
110,會耦接於閘極驅動線GL-2。另一方面,耦接於編號為偶數的源極驅動線SL(例如,源極驅動線SL-2和SL-4等等)的另一部分畫素電路110,會耦接於閘極驅動線GL-3。
請參照第2圖,顯示面板100另包含電極矩陣200。電極矩陣200用於提供多個極性控制訊號Sbo-1~Sbo-n至畫素電路110,其中極性控制訊號Sbo-1~Sbo-n用於與資料訊號Sda-1~Sda-n互相配合以驅動液晶進行極性反轉。另外,電極矩陣200包含多列R-1~R-n以及多行C-1~C-n之電極210。
針對行C-1的電極210而言,位於編號為奇數的列R(例如,列R-1和R-3等等)上的部分電極,會彼此耦接且用於提供極性控制訊號Sbo-1。
針對行C-1和C-2的電極210而言,位於行C-1與編號為偶數的列R(例如,列R-2和R-4等等)的交叉點上的部分電極210,會耦接於位於行C-2與編號為奇數的列R(例如,列R-1和R-3等等)的交叉點上的另一部分電極210。並且,位於行C-1與編號為偶數的列R的交叉點上的部分電極210,以及位於行C-2與編號為奇數的列R的交叉點上的另一部分電極210,都用於提供極性控制訊號Sbo-2。
針對行C-2和C-3的電極210而言,位於行C-2與編號為偶數的列R(例如,列R-2和R-4等等)的交叉點上的部分電極210,會耦接於位於行C-3與編號為奇數的列R(例如,列R-1和R-3等等)的交叉點上的另一部分電極
210。並且,位於行C-2與編號為偶數的列R的交叉點上的部分電極210,以及位於行C-3與編號為奇數的列R的交叉點上的另一部分電極210,都用於提供極性控制訊號Sbo-3。電極矩陣200中其餘電極210的連接方式依此類推,為簡潔起見,在此不重複贅述。
電極矩陣200還包含多個畫素區域220,其中每個畫素區域220代表可用於設置一個畫素電路110和一個對應的電極210於其中的區域。亦即,每個畫素區域220會包含一組互相耦接的電極210和畫素電路110。
如第2圖所示,每個電極210具有多個相鄰電極210。若某一電極210與相鄰電極210位於同一列或同一行,則該某一電極210的電壓極性會相反於相鄰電極210的電壓極性。若某一電極210與相鄰電極210位於不同列且不同行,則該某一電極210的電壓極性會相同於相鄰電極210的電壓極性。
以位於列R-2與行C-2的交叉點的電極210為例(為方便說明,下文簡稱為目標電極),目標電極具有八個相鄰電極210。在該八個相鄰電極210中,位於列R-2的兩個相鄰電極210以及位於行C-2的兩個相鄰電極210,會具有與目標電極相同的電壓極性。其餘四個分別位於列R-1與行C-1的交叉點、列R-1與行C-3的交叉點、列R-3與行C-1的交叉點以及列R-3與行C-3的交叉點的相鄰電極210,則具有與目標電極不同的電壓極性。
因此,於畫素矩陣PA的任一列畫素電路110之
中,分別位於相鄰兩行的兩個畫素電路110,會接收到電壓極性相反的極性控制訊號Sbo。亦即,畫素矩陣PA可用點反轉的方式驅動。
第3圖為依據本揭示文件一實施例的畫素電路110簡化後的示意圖。畫素電路110包含第一開關T1、第二開關T2、儲存電路Cst以及液晶電容Clc。
第一開關T1包含第一端、第二端和控制端。第一開關T1的第一端用於接收資料訊號Sda。第一開關T1的第二端耦接於第一節點N1。
儲存電路Cst耦接於第一節點N1,且用於接收共同電壓Vcom。液晶電容Clc耦接於第一節點N1和儲存電路Cst之間。
第二開關T2包含第一端、第二端和控制端。第二開關T2的第一端耦接於儲存電路Cst。第二開關T2的第二端用於接收極性控制訊號Sbo。當第一開關T1和第二開關T2的其中一者導通時,第一開關T1和第二開關T2其中的另一者也會導通,以傳送資料訊號Sda與極性控制訊號Sbo至儲存電路Cst以及液晶電容Clc。
具體而言,儲存電路Cst包含第一電容C1和第二電容C2。第一電容C1包含第一端和第二端。第一電容C1的第一端耦接於第一節點N1。第一電容C1的第二端耦接於第二節點N2,其中第二開關T2的第一端也耦接於第二節點N2。第二電容C2包含第一端和第二端。第二電容C2的第一端耦接於第二節點N2。第二電容C2的第二端用於接收共
同電壓Vcom。
值得一提的是,液晶電容Clc的兩端分別耦接於第一節點N1和第二節點N2。
在本實施例中,第一開關T1的控制端與第二開關T2的控制端互相耦接,且皆用於接收第一控制訊號Sc1。因此,第一開關T1和第二開關T2可同時導通或關斷。
實作上,第一開關T1和第二開關T2可以用N型薄膜電晶體(thin-film transistor)來實現,或是用其他合適種類的N型電晶體來實現。
以下將以第3圖配合第4圖來進一步說明畫素電路110的運作。如第4圖所示,於寫入期間,第一控制訊號Sc1處於致能準位(例如,高電壓準位),使得第一開關T1和第二開關T2都處於導通狀態。在此情況下,資料訊號Sda會經由第一開關T1被傳輸至第一節點N1,且極性控制訊號Sbo會透過第二開關T2傳輸至第二節點N2。
接著,於發光期間,第一控制訊號Sc1會處於禁能準位(例如,低電壓準位),使得第一開關T1和第二開關T2都處於關斷狀態。
在本實施例中,極性控制訊號Sbo的相位與資料訊號Sda的相位會彼此相反。並且,極性控制訊號Sbo的大小的絕對值,會相同於資料訊號Sda的大小的絕對值。
舉例來說,在第一幀畫面的寫入期間,當資料訊號Sda的電壓準位為4V時,極性控制訊號Sbo會具有-4V的電壓準位。因此,液晶電容Clc的兩端之間會具有正電壓
差(例如,8V)。在第一幀畫面之後的第二幀畫面的寫入期間,當資料訊號Sda的電壓準位為-2.2V時,極性控制訊號Sbo會具有2.2V的電壓準位。因此,液晶電容Clc的兩端之間會具有負電壓差(例如,-4.4V)。藉由前述運作,便可以實現液晶的極性反轉。
在某些實施例中,第一開關T1和第二開關T2是用P型電晶體來實現。在此情況下,第一控制訊號Sc1的致能準位為低電壓準位,而第一控制訊號Sc1的禁能準位為高電壓準位。
第5圖為依據本揭示文件一實施例的多個第一控制訊號Sc1-1~Sc1-n、多個資料訊號Sda-1~Sda-n、多個極性控制訊號Sbo-1~Sbo-n以及共同電壓Vcom簡化後的於一幀畫面期間的波形示意圖。如第5圖所示,一幀畫面可細分為n個子時段P-1~P-n,其中n為正整數且等於閘極驅動線GL-1~GL-n的總數。於子時段P-1~P-n之中,第一控制訊號Sc1-1~Sc1-n會依序自禁能準位切換至致能準位。
例如,於子時段P-1,第一控制訊號Sc1-1處於致能準位,而其他的第一控制訊號Sc1-2~Sc1-n則處於禁能準位。於子時段P-1,第一控制訊號Sc1-2處於致能準位,而其他的第一控制訊號Sc1-1和Sc1-3~Sc1-n則處於禁能準位。於子時段P-3,第一控制訊號Sc1-3處於致能準位,而其他的第一控制訊號Sc1-1、Sc1-2和Sc1-4~Sc1-n則處於禁能準位,依此類推。
每當子時段P-1~P-n的其中一者開始時,資料訊號Sda與極性控制訊號Sbo會改變電壓準位,而共同電壓Vcom則會維持於固定電壓準位。亦即,在每一幀畫面中,資料訊號Sda與極性控制訊號Sbo的電壓準位會改變n次。
在另外一些實施例中,如第6圖所示,極性控制訊號Sbo會於多個預設電壓準位之間切換。亦即,極性控制訊號Sbo的大小的絕對值,可以不同於資料訊號Sda的大小的絕對值。
第7圖為依據本揭示文件另一實施例的畫素電路110a簡化後的示意圖。畫素電路110a相似於畫素電路110,差異在於第一開關T1的控制端以及第二開關T2的控制端沒有互相耦接。第一開關T1的控制端用於接收第一控制訊號Sc1,而第二開關T2的控制端則用於接收第二控制訊號Sc2,其中第二控制訊號Sc2是由閘極驅動器120所提供。因此,第一開關T1和第二開關T2可以同時切換,也可以不同時切換。
例如,在某些實施例中,第一控制訊號Sc1會先自禁能準位切換至致能準位,然後第二控制訊號Sc2才自禁能準位切換至致能準位。因此,第一開關T1會先被導通,然後第二開關T2才接著導通。
又例如,在另外一些實施例中,第二控制訊號Sc2會先自禁能準位切換至致能準位,然後第一控制訊號Sc1才自禁能準位切換至致能準位。因此,第二開關T2會先被導通,然後第一開關T1才接著導通。
前述畫素電路110的其餘連接方式、元件、實施方式以及優點,皆適用於畫素電路110a,為簡潔起見,在此不重複贅述。
在某些實施例中,顯示面板100包含多個邊緣電場切換液晶單元(fringe-field switching crystal cell,未繪示於第1圖)。如第8圖所示,每個邊緣電場切換液晶單元包含平坦保護層(over coating,簡稱OC)810、彩色濾光片層820、液晶層830、薄膜電晶體層840以及屏蔽層850。為使圖面簡潔而易於說明,邊緣電場切換液晶單元的其他元件並未繪示於第8圖中。
薄膜電晶體層840包含第一氧化銦錫(first indium tin oxide,簡稱ITO)層842、第二氧化銦錫層844、保護層(passivation layer)846、金屬層848、第一開關T1以及第二開關T2。第一氧化銦錫層842耦接於第一開關T1的第一端,且用於傳輸資料訊號Sda至第一開關T1。金屬層848透過第二氧化銦錫層844耦接於第二開關T2的第二端,且用於透過第二氧化銦錫層844傳輸極性控制訊號Sbo至第二開關T2。
邊緣電場切換液晶單元的第一開關T1和第二開關T2,分別對應於畫素電路110或110a的第一開關T1和第二開關T2。亦即,畫素電路110或110a構成邊緣電場切換液晶單元的一部份。
綜上所述,當資料訊號Sda和極性控制訊號Sbo都傳輸至畫素電路110或110a內部時,共同電壓Vcom以及
第二電容C2能共同使第二節點N2的電壓維持穩定。因此,液晶電容Clc兩端之間的電壓差便能被準確地控制於預期的數值。
在說明書及申請專利範圍中使用了某些詞彙來指稱特定的元件。然而,所屬技術領域中具有通常知識者應可理解,同樣的元件可能會用不同的名詞來稱呼。說明書及申請專利範圍並不以名稱的差異做為區分元件的方式,而是以元件在功能上的差異來做為區分的基準。在說明書及申請專利範圍所提及的「包含」為開放式的用語,故應解釋成「包含但不限定於」。另外,「耦接」在此包含任何直接及間接的連接手段。因此,若文中描述第一元件耦接於第二元件,則代表第一元件可通過電性連接或無線傳輸、光學傳輸等信號連接方式而直接地連接於第二元件,或者通過其他元件或連接手段間接地電性或信號連接至該第二元件。
另外,除非說明書中特別指明,否則任何單數格的用語都同時包含複數格的涵義。
以上僅為本揭示文件的較佳實施例,凡依本揭示文件請求項所做的均等變化與修飾,皆應屬本揭示文件的涵蓋範圍。
