Abstract
【解決手段】表示パネルの駆動装置は、複数の陽極線CLと複数の走査線RLとの各交点にEL素子41が接続された表示パネル40に対して、陽極ドライバ50と陰極ドライバ60が接続されている。選択された陰極線RLに接続されたEL素子41の寄生容量をプリチャージする工程において、「0」検出手段70aにより、複数の陽極線CLの全てのデータがゼロであることを検出すると、この検出結果に基づき、制御手段84aにより、選択された陰極線RLを含め、陰極線RLの走査時間の間、陰極線RLの全てを“H”に切り替える。
【選択図】図1
Description
(1) EL素子11は、駆動電流Iにほぼ比例した輝度Ltで発光する。
(2) EL素子11は、駆動電圧Vが発光閾値電圧Vth以上の場合において、急激に電流Iが流れて発光する。これに対して、駆動電圧Vが発光閾値電圧Vth以下の場合には、EL素子11には電流が殆ど流れず発光しない。輝度特性は、発光閾値電圧Vthより大なる発光可能領域においては、それに印加される駆動電圧Vの値が大きくなるほど、その発光輝度Ltが大きくなる特性を有している。
図1は、本発明の実施例1におけるパッシブ駆動型表示パネルの駆動装置を示す概略の構成図である。
図5は、図1の駆動装置の陰極リセット法における陽極電圧制御の陰極動作を示す模式的なタイムチャートであり、t0はリセット開始時刻、t1はリセット終了後に短時間に行われるプリチャージ開始及び終了付近の時刻である。
本実施例1によれば、陽極データの全データが黒色となる「0」の場合、タイミング制御回路70内の「0」検出手段70aをアサートし、陰極ドライバ制御回路84内の制御手段84aにより、陰極ドライバ60の出力において、当該スキャンラインも含めた全ラインを、当該スキャンライン時間の間、全ラインを“H”に設定する構成にしている。これにより、駆動装置における回路規模の複雑化や回路規模の増大を抑制しつつ、全陽極データ黒時、陰極リセット法やスキャンを未実施にする制御が可能となり、不要な寄生容量のプリチャージを防止でき、擬似発光を無くし、且つ消費電力の削減が可能となる。
本発明は、上記実施例に限定されず、種々の利用形態や変形が可能である。この利用形態や変形例としては、例えば、次の(A)、(B)のようなものがある。
