Description

發明背景 本發明係有關驅動電漿顯示器之方法,特別是有關驅 動其中每個顯示訊框均包括多個子訊框且利用發光子訊框 達到漸層顯示的一個電漿顯示器之方法。 電漿顯示器(PD)由於自己會發光,因此具有不錯的可 見性,其相當薄,並可做成大螢幕及高速顯示器,因此廣 受矚目而成為CRT顯示器的一個代替品。 第1圖繪示了 PD裝置的一個基本結構圖。 如第1圖中所示,在一塊電漿顯示器面板(pDp) 1 〇中, 電極(第電極··持續電極)X1、X2、·.·與γ電極(第二電極: 掃瞄電極)依序相鄰排列,而定址電極(第三電極)八卜八2、… 朝…X及Y電極方向垂直之方向排列,有一條顯示線於一對 X電極與Y電極之間形成,亦即介於XI與Y1、X2與Y2、依 此類推’而有-個顯示單元(下文簡稱為單元)於一條顯示 線和一個定址電極交叉點形成。 X電極乃共同接至一個X持續電路14,並傳輸相同之驅 動信號;γ電極則個別接至一個γ掃瞄驅動器12,並有一個 掃猫脈衝於㈣敘述之定址作时連續傳至該處,否則υ 持續電路13會產生相同之驅動信號。定址電極係接至一個 定址驅動器1卜並有-個與定址作用中之掃猫脈衝同步的 定址信號供選擇ON單元及㈣單元,否料有相同之驅動 信號傳至該處。有一個控制電路15輪出一個控制上述各元 件之信號。 第2圖繪不了顯示訊框的一個結構圖,以描述pDp裝置 本紙張尺度適用中國國家標準(CNS) A4^ (210X297^7 ------- 511054 A7 —__B7_ 五、發明説明(2 ) 中的驅動序列。由於電漿顯示器之放電僅有兩種狀態,亦 即ON狀態及OFF狀態,顯示器之漸層可由發光次數表示。 因此,與一顯示器對應之顯示訊框被分割成多個如第2圖中 繪示的子域,每個子域包括有重置週期、定址週期以及持 、、只週期。於重置週期中’不論各單元在前一領域中為ON 或OFF,均會完成將所有單元轉成一致狀態的動作,例如 消除壁電荷或一致形成壁電荷之狀態。於定址週期中,會 完成選擇性放電(定址放電),以根據顯示數據判定一單元 是否為ON或OFF狀態,而導致下一個持續週期中發光放電 所需的壁電荷係在處於ON狀態的一個單元上面形成。於持 續週期中,會重複完成放電,而使定址週期中轉成〇N狀態 之單元發光。持續週期之長度、亦即發光次數,會隨子域 之不同而不同,並可藉將發光次數設定成例如1:2:4:8的一 個比例,呈現出漸層顯示效果,並根據漸層效果將若干子 域合併,而使每個單元能夠發光。 第3圖繪示了驅動電漿顯示器之傳統方法範例的一個 波形圖。如圖所示,於重置週期中,有一個較放電起始電 壓、例如300V大的一個電壓vw脈衝作用於χ電極,此脈衝 之作用會使每個單元不論在先前子域中的狀態為〇N或 OFF,均會發生一次放電,並形成壁電荷。當此脈衝移除 後,由於壁電荷本身之作用,會再度發生一次放電,且由 於電極之間無電位差,放電產生的空間電荷會被抵銷,並 達到一致之狀態而不會產生任何壁電荷。於定址週期中, 有一個掃瞄脈衝連續作用於γ電極,並有一個定址脈衝(定 本紙張尺度適用巾_家_ (請先閲讀背面之注意事項再填寫本頁)
