Description
546621 五、發明說明α) 本發明係關於電漿顯示面板定址和驅動方法。 JP10-171399(日立)記載共平面型電漿面板,包括: 一後瓷磚,設有第一行列電極; 一前瓷磚,與後瓷磚平行,設有第二行列成對電極 ,與第一行列電極正交,各對電極在其間留有放電空間, 位於第一行列電極與第二行列成對電極交會處。 此種電漿顯示面板之定址和驅動,一般包括如下步 驟:
一在要作動的各交會區作動放電,利用在後瓷磚電 極和在此區交會的前竟碑一電幾間施以至少一位址電壓脈 波; 一在此區再作動一連串放電,利用在前瓷磚的同樣 電極與此同樣瓷碑的成對電極間,施以一連串的持續電壓 脈波。 按照此法,位址放電在充填放電氣體,把瓷磚分開的 空間内,基本上垂直於瓷磚延伸;相對地,持續放電是沿 前瓷碑基本上平行於瓷碑延伸。
按照習知方法,持續脈波的瞬時頻率一般約1 0 0至3 0 0 仟赫,決定面板的光度;若成對的二電極相對於位址電極 始終為正或零電位,則持續脈波稱為「正」,相反地,若 此電位輪流正、負(同一對的電極之持續信號則偏差半相) ,則稱為「負」或「偶極」。 位址脈波可以組合在一起成為列組,也是很接近在一 起。
第5頁 546621 五、發明說明(2) 為定址和驅動此種面板,jPl〇-171399(日立)亦倡議 使用實質上超過10MHz的很高頻率之脈波。 如該專利的第3圖所示,若第一行列電極包括電極A” Α2· · · A6,且第二行列包括成對(X,γ】),(X,γ2)· · · (X,γη), 於此參見該專利第1圖,則共平面電槳顯示面板的定址和 驅動包括下列步驟: —在施加於電極Ym的信號107和施加於電極Α的信號 1 〇 8之間相差引起位址電壓脈波之際,定址或書寫(階段IV ); 一藉施加信號1 〇 1持績偶極,在電極Ym和成電電極X 之間產生「低頻」持續電壓脈波; 一按照該專利提供的發明,在此持續階段,於用作 陰極的電極Xn或X之一的側面,又施加極高頻率rf信號1〇〇 ;於此應用此信號相當於持績步驟νπ。 按照該專利,施加極高頻率信號之目的是,於習知持 續放電後,一旦在電極間已形成充電,即可防止離子充電 到達陰極,並在電極間振動離子充電,如該專利第4—通圖 簡略表示,參見第5圖,該專利教示: 一在相當於脈波1 〇 1的習知持續放電造成在涵蓋電 極的介質層上充電完全反相之前,必須開始施加RF信號 1 0 0 ;因此,把脈波前端1 〇丨與RF信號第一前端分開的時間 td ’必須實質上比持續放電和充電完全反相的累計時間為 短; 一 RF信號100的半週tw對離子充電要足夠短到,在

546621 五、發明說明(4) 171399所擬之不同方式使用習知共平面式面板,以便能在 低頻穩定放電,而不需提高點引穩定放電所需電壓。 為此目的,本發明標的為共平面式電漿顯示面板之驅 動方法,包括: —第一瓷磚,設有至少第一行列電極; 一第二瓷碑,與第一瓷磚平行,設有至少第二行列 之成對電極,其總體方向與第一行列電極大約正交,各對 電極在其間留有放電區,位於第一行列電和第二行列電極 交會處; 此方法包括:
一應用至少一連串持續電壓脈波,以便在需要持續 放電的各交會區發生持續放電’和 一在該脈波至少其一發生持續放電後,於跨越該區 的一對二電極間,應用足以穩定該放電的高頻脈波列, 其特徵為,該持續電壓脈波係應用於該對之一電極和 跨越該區的第一瓷磚電極之間者。 一般而言,第一瓷磚為「後」瓷磚,而第二瓷磚為面 向顯示影像觀察者之「前」瓷磚;電極交會區形成面板之 放電電池,該電池是否可彼此獨立驅動、作動,視施加於 電極的電壓脈波而定。
由於持續電壓脈波不施加於同樣電極之間,作為放電 穩定脈波列,故可增加前瓷磚穩定電極間之距離,不影響 持續所需電壓;因此可用習知共平面結構,但: 一與習知技藝不同,持續脈波係施加於第一瓷磚的
