脈衝時,將一同步脈衝施加至沒有施加該壁電荷增強脈 衝之其他掃描電極線和維持電極線,使得該同步脈衝和 該由壁電荷所增強的脈衝同步化。 該同步脈衝為一方波。 該同步脈衝被設定爲具有和該第一維持脈衝相同 的電壓值。 該壁電荷增強脈衝具有一負極性電壓。 該壁電荷增強脈衝為一傾斜下降的斜面脈衝。 該壁電荷增強脈衝下降到從-80V至-60V的電壓範 圍。 該壁電荷增強脈衝下降到從-72V至-68V的電壓範 圍。 該壁電荷增強脈衝之應用時間被設定為於2// s和 3 // s之間的範圍中内。 該壁電荷增強脈衝,於一畫面中包含的所有子圖場 之維持周期内施加。 13 1259429 除了最後一個以外的剩餘子圖場,該壁電荷增強脈 衝,係於一晝面中包含的複數個子圖場之維持周期内施 加。 該壁電荷增強脈衝僅於以低溫環境驅動該面板時 施加。 第六圖為顯示於一選擇性消除子圖場的周期内提 供之一驅動脈衝,其用以解釋根據本發明第一實施例的 驅動電漿顯示面板之方法。 請參閱第六圖,一選擇性消除模式的第一子圖場包 含一重設周期、整個寫入周期、一消除定址周期和一維 持周期,而該選擇性消除模式的剩餘子圖場僅包含一消 除定址周期和一維持周期。 亦即,在一晝面的第一子圖場中,在整個放電單元 中産生整個寫入放電。而且在剩餘子圖場中循序關閉非 必需的放電單元,顯示相對應於資料的一影像。 在第一子圖場的重設周期和整個寫入周期,可供應 多種形狀的脈衝。爲了方便解釋,將以均為普遍使用的 斜面脈衝(Ramp Pulse,RP)和整個寫入脈衝(Writing Pulse, WP),來描述該重設周期和該整個寫入周期的運作。 於該第一子圖場的重設周期内,將該斜面脈衝RP 供應至該掃描電極線Y。如果將該斜面脈衝RP供應至該 掃描電極線Y,則在所有放電單元中産生一斜面放電並 且由該斜面放電形成預定的壁電荷。在這時,在該掃描 電極線Y形成負(-)極性的壁電荷,並且在該維持電極 14 1259429 線z形成土( + )極性的壁電荷。 於該第+圖場的整個寫入周期内 =W P供應至該維持電極線z和該掃插=餐個寫入脈 打,百先將整個寫入脈衝WP供應至該^ ^線γ。在這 得它和在重設周期㈣成的壁電荷之=持電極線Z使 地,如果將整個寫入脈衝WP供應至敦疊。同樣 該掃描電極線γ,則在放電單S中形成、切電極線2和 的足夠壁電荷。 維持放電所需 Η之後,於該消除定址周期内,將-消Μ 供應至該定址料線X,並且將_脈衝咖 供應至該掃描電極線Υ。於是,在脈衝sescn f脈衝SED和該消除掃描脈衝SESC二:了該消除數 壁電荷。電,因而消除於整個寫c :維持周期的啟始點,將一啟始 應至該維持電極績 μ哥脈衝WISIJS供

生一南的電壓差值,使得產生一強烈的增強放電。另外, 因爲該第一壁電荷增強脈衝SRi被以一斜面脈衝作供 應’所以由增強的放電在該開啟單元中形成如第七b ^ 所示的大量壁電荷。在本發明中,將該第一壁電荷增= 脈衝SR1的電壓值設定為在-8〇v和-6〇v之間,較^為 在-72V和-68V之間,使得在該開啟單元中形成足夠二^ 量壁電荷。而且,將该第二壁電荷增強脈衝SR2的電壓

時供應。換句話說,當在高於該低溫的溫度下驅動面板 時,可以不供應該第一和第二壁電荷增強脈衝SR1、 SR2,而只在低溫驅動面板時,供應該第一第二壁電荷 增強脈衝SRI、SR2。如此,如果在低溫環境供應該第一 和第二壁電荷增強脈衝SR1、SR2,則其可以在低溫以穩 定的方式驅動面板。 第二實施例 根據本發明之第二實施例,其提供一種驅動電漿顯 示面板之方法,其一晝面中包含複數個選擇性寫入子圖

該方法進一步包含以下步驟:當施加一壁電荷增強 脈衝時,將一同步脈衝施加至沒有施加該壁電荷增強脈 衝之其他掃描電極線和維持電極線,使得該同步脈衝和 18 1259429 該壁電荷增強脈衝同步化。 該同步脈衝為一方波。 電壓ί同步脈衝被設定爲具有和該第—維持脈衝相同的 $由壁電荷所增強的脈衝具有—負極性電壓。 衝。該由壁電荷所增強的脈衝為一傾斜下降的斜面脈 電壓I:壁電荷所增強的脈衝下降到從撕至猶的

一大於0的正整數)子圖場SF1到SFm。除了該第m個 子圖場SFm以外的每一個第一個到第m-Ι個子圖場SF1 到SFm-1,經由將其分爲用於在整個螢幕的單元中均勻 形成一定量壁電荷之一重設周期,用於使用一寫入放電 以選擇開啟單元之一寫入定址周期,用於在所選的開啟 單元中産生一維持放電之一維持周期,以及用於在該維 持放電之後以消除在單元中的壁電荷之一消除周期而驅 動。 該第m個子圖場SFm為選擇性寫入子圖場WSF的 最後一個子圖場,其被.分爲一重設周期、一寫入定址周 期和一維持周期。該選擇性寫入子圖場WSF的重設周 期、寫入定址周期和消除周期被設定為每個子圖場SF1 到SFm具有相同的亮度加權,但是其維持周期被設定為 具有相同或不同的亮度加權。 該選擇性消除子圖場ESF包含n-m個(其中,η是 一大於m的正整數)子圖場SFm+1到SFn。其第m+1 到第η個子圖場SFm+1到SFn中的每一個被分爲用於使 用一消除放電以選擇關閉單元之一消除定址周期,以及 用於在開啟單元中産生一維持放電之一維持周期。在該 20 1259429 選擇性消除子圖場ESF的子圖場SFm+l到SFn中,其 消除定址周期被設定爲相同,並且根據一相對亮度比率 設定該維持周期為相同或不同。 第九圖為顯示於一選擇性消除子圖場和一選擇性寫

除放電,因而消除一些多餘地形成的壁電荷。同時,當 將該斜面下降脈衝RPSD供應至該掃描電極線Y時,一 正極性的直流電(DC)電壓(Va)被供應至該維持電極線 Z。 於一寫入定址周期内,當將一負極性的寫入掃描脈 衝SWSCN被依序供應至該掃描電極線Y時,同時將一 寫入資料脈衝SWD供應至該定址電極線X,使得它與該 寫入掃描脈衝SWSCN同步。然後,當該寫入掃描脈衝
