Description
図1は、図9との対比により本発明の実施例1の表示装置を示すブロック図である。この表示装置31において、上述した表示装置1、11、21と同一の構成は対応する符号を付して示し、重複した説明は省略する。
以上の構成において、この実施例の表示装置31では(図1)、水平駆動回路35及び垂直駆動回路34による信号線SIG及び走査線SCNの駆動により順次ライン単位で表示部32の画素23に信号線SIGの信号レベルVsigが設定されると共に、この設定された信号レベルVsigにより各画素33の有機EL素子8が発光し(図9参照)、所望の画像が表示部32で表示される。
以上の構成によれば、事前に、表示に供する階調が増大するに従って電圧が降下する可変基準電圧により信号レベル保持用コンデンサの他端の電圧を設定した後、表示に供する階調に対応して階調が増大するに従って電圧が増加する階調電圧を信号レベル保持用コンデンサの一端に設定することにより、信号線をダイナミックレンジの小さな駆動信号で駆動して、高い輝度を確保することができる。
