Description

顯示裝置及其製造方法
本發明有關於顯示技術領域,特別有關於一種顯示裝置及其製造方法。
近年來,隨著資訊技術、無線移動通訊和資訊家電的快速發展與應用,人們對電子產品的依賴性與日俱增,更帶來各種顯示技術及顯示裝置的蓬勃發展。顯示裝置具有完全平面化、輕、薄、省電等特點,因此得到廣泛的應用。
為了降低顯示裝置的製造成本並藉此實現窄邊框的目的,在製造過程中通常採用GIP(Gate in Panel,閘極面板)技術,直接將閘極驅動電路(即GIP電路)集成於顯示螢幕上。顯示螢幕通常包括用於顯示圖像的顯示區域和圍繞顯示區域的非顯示區域,該顯示區域中設置有多條掃描線和多條資料線,該多條掃描線和資料線交叉限定出多個呈矩陣排列的像素單元,該非顯示區域中設置有GIP電路,該GIP電路藉由掃描線與該像素單元連接。
隨著顯示技術的發展,顯示螢幕的形狀也向多元化方向發展,除了傳統的矩形之外,還有多邊形、圓形等形狀。例如,手錶採用圓形的顯示螢幕。在矩形的顯示螢幕中,每行像素的個數以及每列像素的個數通常是一致的。而在多邊形或圓形的顯示螢幕中,每行像素的個數以及每列像素的個數是不一致的。
由於每列像素個數不一致,因此資料線上的寄生電容不一致,進而造成顯示裝置出現顯示不均現象。為此,需要在顯示裝置中設置補償電容,利用該補償電容對寄生電容進行補償,才能獲得顯示均勻的圖像。然而,現有的顯示裝置中補償電容的佔用面積較大,導致掃描線無法與GIP電路連接,不利於窄邊框的實現。
基此,如何解決現有的顯示裝置由於補償電容的佔用面積過大,導致掃描線無法與GIP電路連接的問題,成了本領域技術人員極待解決的一個技術問題。
本發明的目的在於提供一種顯示裝置及其製造方法,以解決現有技術中顯示裝置由於補償電容的佔用面積過大,導致掃描線無法與GIP電路連接的問題。

以下結合附圖和具體實施例對本發明提出一種顯示裝置及其製造方法作進一步詳細說明。根據下面說明和請求項,本發明的優點和特徵將更清楚。需說明的是,附圖均採用非常簡化的形式且均使用非精準的比例,僅用以方便、清晰地輔助說明本發明實施例的目的。
請結合參考圖1至圖5,該顯示裝置的製造方法包括:步驟一:提供一基板100;步驟二:在該基板100上形成一多晶矽層;步驟三:圖案化該多晶矽層以形成多個多晶矽區塊110; 步驟四:對該多個多晶矽區塊110進行離子注入;步驟五:在該多個多晶矽區塊110上形成一閘極絕緣層(圖中未示出);步驟六:在該閘極絕緣層上形成一第一導電層;步驟七:圖案化該第一導電層以形成多條資料線120,該多條資料線120與該多個多晶矽區塊110部分式交疊以形成補償電容。
具體的,首先,如圖1所示,提供一基板100,該基板100包括顯示區和圍繞於該顯示區的非顯示區,該顯示區用於設置像素陣列,該像素陣列包括多個呈陣列方式排列的像素單元101,每個像素單元101包括像素電容和薄膜電晶體(圖中未示出),該非顯示區用於設置GIP電路140和測試電路150。
接著,如圖2所示,在該基板100上形成多晶矽層,並藉由刻蝕技藝對其進行圖案化,以形成各像素單元101的該像素電容的第一極板(圖中未示出)、該薄膜電晶體的源極、汲極(圖中未示出)和位於像素單元101以外區域上的多個多晶矽區塊110。在圖2所示實施例中,該多個多晶矽區塊110位於像素單元101與測試電路150之間。優選的,該多個多晶矽區塊110全部位於非顯示區。
此後,採用硼離子或磷離子對該像素電容的第一極板和多晶矽區塊110進行離子注入技藝,藉由離子注入技藝使得該第一極板和多晶矽區塊110均摻雜有雜質,由此提高該第一極板和多晶矽區塊110的導電性。
然後,在圖案化的多晶矽層上形成一閘極絕緣層,並圖案化該閘極絕緣層。
之後,如圖3所示,在圖案化的閘極絕緣層上形成第一導電層,並藉由刻蝕技藝對其進行圖案化,以形成該像素電容的第二極板(圖中未示出)、該薄膜電晶體的閘極(圖中未示出)和多條資料線120,該多條資料線120的一端與像素單元101連接,該多條資料線120的另一端與測試電路150連接,且該資料線120與該多晶矽區塊110部分式交疊以形成補償電容。
其中,該補償電容的電容補償值與資料線120與多晶矽區塊110的交疊面積成正比。
本實施例中,資料線120與多晶矽區塊110的交疊面積根據資料線120所連接的像素單元101的數量進行調整。其中,資料線120所連接的像素單元101的數量越少,意味著資料線120上的寄生電容越小,因此資料線120對應的補償電容的電容補償值要求越高,即資料線120與多晶矽區塊110的交疊面積要求越大。反之,資料線120所連接的像素單元101的數量越多,意味著資料線120上的寄生電容越大,因此資料線120對應的補償電容的電容補償值要求越低,即資料線120與多晶矽區塊110的交疊面積要求越小。
在該顯示裝置的製造過程中,若資料線120所連接的像素單元101的數量較少,則增加資料線120與多晶矽區塊110的交疊面積;若資料線所連接的像素單元的數量較多,則減少資料線120與多晶矽區塊110的交疊面積。
此後,如圖4所示,在該多個多晶矽區塊110中進行接觸孔技藝以形成多個接觸孔110a,該多個接觸孔110a為半透孔,即該多個接觸孔110a的深度小於多晶矽區塊110的厚度,使得該 多個接觸孔110a的底部暴露出該多個多晶矽區塊110。
最後,如圖5所示,在圖案化的第一導電層上形成第二導電層,並藉由刻蝕技藝對其進行圖案化,以形成電源線131和像素連線132,該電源線131藉由該多個接觸孔110a與該多個多晶矽區塊110連接,該像素連線132用於連接像素單元與GIP電路140。
其中,該第一導電層和第二導電層採用的材料根據產品的實際要求進行選擇,在此不做限定。該第一導電層和第二導電層可以採用氧化銦錫(ITO)、銦鋅氧化物(IZO)、摻鋯的氧化鋅(ZZO)、摻氟的氧化錫(FTO)或納米銀等透明導電材料,也可以採用銀(Ag)、鋁(Al)、鎢、銀合金、鋁合金等非透明的導電材料。
至此,形成該顯示裝置10。在該顯示裝置10中,補償電容的一側極板由導電層構成,另一側極板由多晶矽區塊110構成。在傳統的顯示裝置中,補償電容的兩側極板通常都是由導電層構成的。
在本實施例提供的顯示裝置的製造方法中,利用該多個多晶矽區塊110構成補償電容的一側極板,不但能夠縮小補償電容佔用的面積,而且製作技藝更加簡單,僅採用2-Metal技藝(即形成兩層金屬層技藝)就能夠完成顯示裝置的製作,因此不必採用3-Metal技藝(即形成三層金屬層技藝)。
相應的,本發明還提供一種顯示裝置。請繼續參考圖5,該顯示裝置10包括:基板100;依序形成於該基板100上的圖案化的多晶矽層、圖案化的閘極絕緣層和圖案化的第一導電層,該圖案化的多晶矽層包括多個多晶矽區塊110,圖案化的第一導電層 包括多條資料線120,該多條資料線120的部分線段與該多個多晶矽區塊110位置交疊而形成補償電容。
具體的,該顯示裝置10包括多條用於提供掃描信號的掃描線(圖中未示出)和多條用於提供資料信號的資料線120,該多條掃描線和資料線120交叉限定出多個呈矩陣排列的像素單元101,每個像素單元101均包括像素電容(圖中未示出)和薄膜電晶體(圖中未示出)。其中,該像素電容的第二極板、該薄膜電晶體的閘極與該多條資料線120在同一技藝中製成(均位於第一導電層中),該像素電容的第一極板、該薄膜電晶體的源極和汲極與該多個多晶矽區塊110在同一技藝中製成(均位於多晶矽層中)。
請繼續參考圖5,圖案化的多晶矽層與圖案化的第一導電層部分位置交疊(即資料線120的部分線段與多晶矽區塊110位置交疊),位於交疊區域的多晶矽層與第一導電層分別構成補償電容的兩側極板,該多晶矽層與第一導電層之間的閘極絕緣層構成該補償電容的絕緣介質層。
本實施例中,該補償電容用於補償資料線120的寄生電容,該補償電容的電容補償值與資料線120與多晶矽區塊110的交疊面積成正比。其中,資料線120與多晶矽區塊110的交疊面積與資料線120所連接的像素單元101的數量相關。資料線120所連接的像素單元101的數量越多,則資料線120與多晶矽區塊110的交疊面積越小,與資料線120相應的補償電容的電容補償值越小。資料線120所連接的像素單元101的數量越少,則資料線120與多晶矽區塊110的交疊面積越大,與資料線120相應的補償電容的電容補償值越大。
當資料線120向該像素單元101提供資料信號時,資料線120傳輸的資料信號同時施加到該補償電容的一側極板上,對資料線120上的寄生電容進行補償。由於,該補償電容的電容補償值是根據資料線120所連接的像素單元101的數量設置的,因此即使該顯示裝置10每列像素單元的個數不一致,也能夠有效地補償資料線120上的寄生電容,不會出現顯示不均現象。
請結合參考圖4和圖5,該顯示裝置10還包括多條電源線131,該多條電源線131的一端與該像素單元101連接,用於向該像素單元101提供電源信號,多晶矽區塊110上設置有多個接觸孔110a,電源線131藉由該多個接觸孔110a與多晶矽區塊110連接。
請繼續參考圖5,該顯示裝置10還包括像素連線132和GIP電路140,該像素連線用於連接該像素單元101和GIP電路140。本實施例中,該多條像素連線132和該多條電源線131在同一技藝中製成(均位於第二導電層中)。
請繼續參考圖5,該顯示裝置10還包括測試電路150,資料線120的一端與該像素單元101連接,資料線120的另一端與該測試電路150連接,該測試電路150用於提供測試信號,該測試信號用於判斷該顯示裝置10是否正常顯示。
本實施例提供的顯示裝置可以是液晶顯示(LCD)裝置、等離子體顯示(PDP)裝置、真空螢光顯示(VFD)裝置、有機發光顯示(OLED)裝置、柔性顯示裝置或者其他類型的顯示裝置,具體類型在此不作限制。
綜上,在本發明實施例提供的顯示裝置及其製造方法中,利用摻雜有雜質的多晶矽層與第一導電層的交疊區域形成資料線的補償電容,以減少該補償電容的佔用面積,從而避免掃描線無法與GIP電路連接的問題。
上述描述僅是對本發明較佳實施例的描述,並非對本發明範圍的任何限定,本發明領域的普通技術人員根據上述揭示內容做的任何變更、修飾,均屬於請求項的保護範圍。
