200905653 九、發明說明: 【發明所屬之技術領域】 本發明係關於一種平面顯示裝置、晝素結構及晝素驅 動方法。 【先前技術】 隨著數位時代的來臨,液晶顯示裝置之技術亦快速成 長,已成為不可或缺的電子產品,故對於液晶顯示裝置之 技術及功能要求亦越來越高。 一般而言,液晶顯示裝置主要係包含一液晶面板以及 一背光模組。其中,液晶面板主要係具有彩色濾光基板、 薄膜電晶體基板以及一夾設於兩基板間的液晶層。而背光 模組係作為背光源使用,其係可將來自一光源的光線均勻 地分佈在液晶面板之表面。 一般而言,人眼所看到的影像,通常係由複數個晝素 所組成,而其中係包含紅色、綠色與藍色畫素。每個晝素 藉由液晶分子依據不同的驅動電壓而旋轉或傾斜時,因旋 轉的角度不同,光線通過液晶所產生的亮度亦不同,因此 可產生不同色階。 當使用者於側視液晶顯示裝置時,通常會造成顏色的 偏移,即色差(color shift)問題。目前的改善方式為,藉由 輸入一驅動電壓至一晝素,並對畫素中之兩個不同電容值 之液晶電容充電,而產生兩種不同晝素電壓,例如一高電 壓及一低電壓,使每個晝素呈現亮區及暗區兩個區域,以 200905653 減少色偏的現象,讓使用者於每個視角所見之色彩亮度皆 較為平均。 一此外,每個畫素都會連接至一個相同的共同電極,故 當使用上述改善方式時,畫素的亮區及暗區亦共同使用一 個/、同電壓。然' 而’當停止送人驅動電壓至晝素時,則因 寄生電容效應,岐晝素電壓之電壓值係分別下降,而其 電壓下降量(feed thi;〇Ug_兩個液晶電容之值不同而不相 同’因而導致亮區及暗區的共同電壓難以控制於相同的準 位故雖改善了色偏的問題,但仍會造成晝面閃燦現象。 因此,如何提供一種能夠避免因寄生電容效應所造成 之電壓下降量,以改善晝面閃爍現象之平面顯示裝置、畫 素結構及晝素驅動方法,正是當前的重要課題之一。 【發明内容】 因卑上述課題,本發明之目的為提供—種能夠改. 產生的電壓下降量,以改善晝面閃爍現象: 千面顯不裝置、晝素結構及晝素驅動方法。 緣是’為達上述目的,佑摅士欢nn ^ ^ ^ 依據本發明之晝素結構係分) 補仏迴路及一資料線驅動支 路電性連接,並包含一第—笼 容、一 $相電晶體、-第-等效1

請同時參照圖i二,及晝素驅動方法。 圖所示,本發明第-實施例之平 11 200905653 面顯示裝置1係具有一平面顯示面板11,而平面顯示面板 11則具有複數個晝素結構111。各晝素結構m係分別與 第一掃描線驅動迴路SL、一補償迴路CL及一資料線驅動 迴路DL電性連接。本實施例之平面顯示裝置1,於實施 上係為一液晶顯示裝置,故平面顯示面板11係為一液晶 顯示面板。 於本實施例中,如圖2所示,畫素結構111係包含一 第一薄膜電晶體Q1、一第一等效電容CA、一第一補償電 容C7、一第二薄膜電晶體Q2、一第二等效電容CB及一 第二補償電容C8。 第一薄膜電晶體Q1係具有一第一閘極G1、一第一汲 極D1及一第一源極S1。而第一閘極G1係與第一掃描線 驅動迴路SL電性連接,第一源極S1與資料線驅動迴路 DL電性連接。 第一等效電容CA係與第一薄膜電晶體Q1之第一汲 極D1電性連接,並具有一第一寄生電容C1、一第一液晶 電容C2以及一第一儲存電容C3。而第一寄生電容C1係 分別與第一薄膜電晶體Q1之第一汲極D1及第一閘極G1 電性連接,第一液晶電容C2及第一儲存電容C3係相互電 性連接,並分別與第一薄膜電晶體Q1之第一汲極D1電性 連接,且第一液晶電容C2係接收一共同電壓VC,而第一 儲存電容C3則接收一儲存電壓VS1。 第一補償電容C7係分別與第一等效電容CA及補償 迴路CL電性連接。 12 200905653 第二薄膜電晶體Q2係具有一第二閘極G2、一第二汲 極D2及一第二源極S2。而第二閘極G2係與第一掃描線 驅動迴路SL電性連接,第二源極S2與資料線驅動迴路 DL電性連接。 第二等效電容CB係分別與第二薄膜電晶體Q2之第 二汲極D2及第二閘極G2電性連接,並具有一第二寄生電 容C4、一第二液晶電容C5及一第二儲存電容C6。而第二 寄生電容C4係分別與第二薄膜電晶體Q2之第二閘極G2 及第二汲極D2電性連接,第二液晶電容C5及第二儲存電 容C6係相互電性連接,並分別與第二薄膜電晶體Q2之第 二汲極D2電性連接,且第二液晶電容C5係接收共同電壓 VC,而第二儲存電容C6則接收一儲存電壓VS2。 第二補償電容C8係分別與第二等效電容CB及補償迴 路CL電性連接。 於本實施例中,第一等效電容CA與第二等效電容CB 於實施上係可為相同或相異之值,在此係以相異之值為 例。 請參照圖3所示,本實施例之第一掃描線驅動迴路SL 係傳送第一掃描訊號SS,而第一掃描訊號SS係具有一第 一子掃描訊號SS1及一第二子掃描訊號SS2。於本實施 中,第一掃描線訊號SS係為一脈波訊號。 本實施例之資料線驅動迴路D.L,係傳送資料訊號(圖 未示),且資料訊號於實施上係為一電壓訊號。 請再參照圖3所示,補償迴路CL係產生補償訊號 13 200905653 cs,而補償訊號CS係具有一第一子補償訊號CS1及一第 二子補償訊號CS2。本實施例之補償迴路CL於實施上係 為一第二掃描線驅動迴路,故補償訊號CS係為一第二掃 描訊號,而第二掃描線驅動迴路係作為驅動另一個晝素結 構111之用。 於本實施例中,第一子掃描訊號SS1及第一子補償訊 號CS1係分別為一低準位,第二子掃描訊號SS2及第二子 補償訊號CS2係分別為一高準位,而且第二子掃描訊號 SS2之相位與第一子補償訊號CS1之相位係相反。 請再同時參照圖2與圖3所示,本實施例之平面顯示 裝置1,其畫素驅動方法如下:晝素結構111係分別與第 一掃描線驅動迴路SL、資料線驅動迴路DL及補償迴路 CL電性連接。 於一第一時間T1,第一薄膜電晶體Q1之第一閘極 G1及第二薄膜電晶體Q2之第二閘極G2係分別接收第一 子掃描訊號SS1,此時,因第一子掃描訊號SS1為低準位, 故第一薄膜電晶體Q1及第二薄膜電晶體Q2皆未導通。 於一第二時間T2,第一薄膜電晶體Q1之第一閘極 G1及第二薄膜電晶體Q2之第二閘極G2係分別接收及依 據第二子掃描訊號SS2為高準位而導通,以使第一薄膜電 晶體Q1之第一源極S1及第二薄膜電晶體Q2之第二源極 S2分別接收資料訊號,此時,第一薄膜電晶體Q1之第一 汲極D1及第二薄膜電晶體Q2之第二汲極D2為相同電 壓。同時,第一補償電容C7及第二補償電容C8係分別接 14 200905653 收第一子補償訊號CS1。 於一第三時間T3,第一補償電容C7及第二補償電容 C8係分別接收第二子補償訊號CS2,而同時,在第一掃描 線驅動迴路SL停止將第一掃描訊號SS的第二子掃描訊號 SS2送入第一薄膜電晶體Q1及第二薄膜電晶體Q2的瞬 間,意即第一子補償訊號CS1轉換到第二子補償訊號CS2 時,係因第一等效電容CA及第二等效電容CB已藉由第 一子補償訊號CS1轉換到第二子補償訊號CS2的改變而得 到補償,故不會產生寄生電容效應,且同時也消除了晝素 結構111的第一晝素電壓VI及第二晝素電壓V2有電壓值 下降(feed through)的問題。 於本實施例中,亦可依據不同需求而藉由第二子補償 訊號CS2分別與第一等效電容CA及第二等效電容CB相 配合,而補償使得晝素結構111的第一晝素電壓VI及第 二晝素電壓V2的改變量相同或不相同,在此即以第一晝 素電壓VI之值大於第二晝素電壓V2之值為例。而此時, 畫素結構111係透過第一晝素電壓VI及第二晝素電壓V2 以呈現一亮區及一暗區。 於一第四時間T4,第一補償電容C7及第二補償電容 C8係分別接收第三子補償訊號CS3,而此時第一補償電容 C7及第二補償電容C8係受到第二子補償訊號CS2轉換到 第三子補償訊號CS3的影響,而分別使第一晝素電壓VI 及第二畫素電壓V2之值拉降至適當的準位。 由於平面顯示裝置1係的晝素結構111,其第一薄膜 15 200905653 電晶體Q1及第二薄膜電晶體Q2分別與第一掃描線驅動迴 路SL及資料線驅動迴路DL電性連接,第一等效電容CA 係分別與第一薄膜電晶體Q1之第一閘極G1、第一汲極 D1及第一補償電容C7電性連接,第二等效電容CB係分 別與第二薄膜電晶體Q2之第二閘極G2、第二汲極D2及 第二補償電容C8電性連接,第一補償電容C7及第二補償 電容C8係分別與補償迴路CL電性連接。晝素結構111係 藉由補償迴路CL之第一子補償訊號CS1轉換為第二子補 償訊號CS2的改變,而透過第一補償電容C7及第二補償 電容C8對第一等效電容CA及第二等效電容CB做補償。 此種方式,即使在停止送入第二子掃描訊號SS2時,第一 等效電容CA及第二等效電容CB因已得到補償,故不僅 不會產生寄生電容效應,更可消除晝素結構111之第一晝 素電壓VI及第二晝素電壓V2有電壓下降的問題,進而改 善晝面閃爍現象。 以下,請參照圖4所示,本發明較佳實施例之一種晝 素驅動方法係應用於上述第一較佳實施例之平面顯示裝 置1

Description of the Invention: [Technical Field] The present invention relates to a flat display device, a halogen structure, and a halogen driving method. [Prior Art] With the advent of the digital age, the technology of liquid crystal display devices has also grown rapidly and has become an indispensable electronic product, so the technical and functional requirements for liquid crystal display devices are also increasing. In general, a liquid crystal display device mainly includes a liquid crystal panel and a backlight module. The liquid crystal panel mainly has a color filter substrate, a thin film transistor substrate, and a liquid crystal layer interposed between the two substrates. The backlight module is used as a backlight to uniformly distribute light from a light source on the surface of the liquid crystal panel. In general, the images seen by the human eye are usually composed of a plurality of elements, including red, green and blue pixels. When the liquid crystal molecules are rotated or tilted according to different driving voltages, the brightness of the light passing through the liquid crystal is different depending on the angle of rotation, and thus different color gradations can be produced. When the user views the liquid crystal display device sideways, it usually causes a color shift, that is, a color shift problem. The current improvement method is to generate two different pixel voltages, such as a high voltage and a low voltage, by inputting a driving voltage to a halogen and charging two liquid crystal capacitors of different capacitance values in the pixel. In order to make each element appear in the bright area and the dark area, the phenomenon of color shift is reduced by 200905653, so that the brightness of the color seen by the user at each viewing angle is relatively average. In addition, each pixel is connected to the same common electrode, so when using the above improvement method, the bright and dark areas of the pixel also use a /, the same voltage. However, when the voltage of the driving voltage is stopped to the halogen, the voltage value of the halogen voltage is decreased by the parasitic capacitance effect, and the voltage drop amount (feed thi; 〇 Ug_ the value of the two liquid crystal capacitors) Different and not the same 'thus, the common voltage of the bright area and the dark area is difficult to control at the same level. Although the problem of color shift is improved, the phenomenon of flashing on the surface is still caused. Therefore, how to provide a kind of parasitic phenomenon can be avoided. The amount of voltage drop caused by the capacitance effect, the planar display device, the pixel structure, and the pixel driving method for improving the flickering phenomenon of the facet are one of the current important topics. [Summary of the Invention] The purpose is to provide a kind of voltage drop that can be changed. In order to improve the flickering phenomenon of the kneading surface: the surface of the device, the structure of the alizarin and the driving method of the alizarin.
