Abstract
【解決手段】 パネルキャパシタCpの一端子と接地端子との間に,ドレインが電気的に接続されたトランジスタM5と,トランジスタM5のゲートに一端子が接続されたキャパシタC2と,キャパシタC2の他端子とトランジスタM5のドレインとの間に,直列に接続された抵抗R1と,キャパシタC2の他端子とトランジスタM5のドレインとの間に,直列に接続されたダイオードD2と,ダイオードD2及び抵抗R1に,並列に接続されたツェナーダイオードD3と,を備えることにより,キャパシタC2に充電される電圧をツェナーダイオードD3で調節して,Yランプ下降区間の初期電圧を,放電が起こる電圧まで低くする。
【選択図】 図6
Description
最後の維持放電が終わると,X電極にはプラス(+)電荷,Y電極にはマイナス(−)電荷が積もる。この状態で,X電極に,0(V)から+Ve(V)に向かって緩やかに上昇する消去ランプ電圧を印加する。すると,X電極とY電極に形成された壁電荷は次第に消去される。
この区間では,アドレス電極及びX電極を0Vに維持し,Y電極に,電圧Vsから電圧Vsetに向かって緩やかに上昇するランプ電圧を印加する。このランプ電圧が上昇している間に,全ての放電セルでは,Y電極からアドレス電極及びX電極にそれぞれ一番目の微弱なリセット放電が起こる。その結果,Y電極に(−)壁電荷が蓄積され,同時にアドレス電極及びX電極には(+)壁電荷が蓄積される。
ついで,リセット区間の後半には,X電極を定電圧+Veに維持したままで,Y電極に,電圧Vsから0(V)に緩やかに下降するランプ電圧を印加する。このランプ電圧が下降する間に,全ての放電セルでは,さらに二番目の微弱なリセット放電が起こる。
まず,第1の実施の形態によるプラズマディスプレイパネルの駆動装置について,図4〜図6を参照して詳細に説明する。図4は,本実施の形態によるプラズマディスプレイパネル装置を示す説明図である。同図に示すように,本実施の形態によるプラズマディスプレイパネル装置は,プラズマパネル100,アドレス駆動部200,Y電極駆動部320,X電極駆動部340,及び制御部400を含む。
第1の実施の形態においては,ツェナーダイオードD3及び抵抗R2をダイオードD2及び抵抗R1に並列に連結したが,第2の実施の形態においては,これと異なり,ツェナーダイオードD3及び抵抗R2を,キャパシタC2と,並列に接続したダイオードD2及び抵抗(抵抗素子)R1と,の間に直列に連結する。本実施の形態の場合,上記以外の回路構成は,第1の実施の形態によるY電極駆動部320の回路と同一であるので,説明を省略する。
