Description
第2の走査線に関する電流駆動能力を意図的に低下させることによって、発光制御トランジスタの駆動パルスの立ち上がり波形を鈍らせ(すなわち、時間に対する電圧の変化を緩やかとし)、これによって、発光制御トランジスタの寄生容量を介して、大きなピーク電流値をもつ瞬時電流(カップリング電流)が流れるのを抑制することができる。したがって、黒表示時における黒レベルの上昇(黒浮き)が低減され、コントラスト低下による表示画像の画質の低下の心配がなくなる。また、走査線駆動回路における第2の走査線に関する駆動能力を調整することは容易であり、特別の回路を設ける必要がないため、回路構成が複雑化することがなく、実現が容易である。
前記第2の出力バッファを構成するトランジスタのサイズは、前記第1の出力バッファを構成するトランジスタのサイズよりも小さい。
Ileak=n×Igel+d×Ioffp+(1−d)×Ioffn・・・・(1)
ここで、nは、1フレーム内の発光回数であり、dは、発光デューティ(1V期間に対する発光期間の割合であり、0≦d≦1)であり、Igelは、GEL信号のカップリングに起因するカップリング電流であり、Ioffpは、PMOSTFT(駆動トランジスタM13)のオフ時のリーク電流(オフ電流)であり、Ioffnは、NMOSTFT(発光制御トランジスタM14)のオフ時のリーク電流(オフ電流)である。

前記アクティブマトリクス型発光装置は、表示装置として、あるいは、光源として使用されることを特徴とする電子機器。 - 発光素子と、前記発光素子を駆動する駆動トランジスタと、前記駆動トランジスタに一端が接続され、書込みデータに応じた電荷を蓄積する保持コンデンサと、前記保持コンデンサへのデータ書込みに関係する動作を制御する、少なくとも一つの制御トランジスタと、前記発光素子と前記駆動トランジスタとの間に介在する発光制御トランジスタと、を備える画素回路における前記制御トランジスタならびに前記発光制御トランジスタを各々、第1および第2の走査線を経由してオン/オフ駆動する、アクティブマトリクス型発光装置における画素駆動方法であって、
前記第1の走査線を第1のドライバ回路によって駆動し、前記第2の走査線を第2のドライバ回路によって駆動すると共に、前記第2の走査線の電位の変化が生じてから、その変化が収束するまでの時間が、1水平同期期間(1H)以上となるように、前記第2のドライバ回路の電流駆動能力を、前記第1のドライバ回路の電流駆動能力に比べて低く設定し、これによって、前記第2の走査線の電位を変化させて前記発光制御トランジスタをオフからオンに移行させる際に、前記発光制御トランジスタのゲート・ソース間の寄生容量を経由して、前記第2の走査線の電位の変化成分が前記発光素子側に洩れ込むことによって生じるカップリング電流を低減し、黒表示時における前記発光素子の不要な発光を抑制することを特徴とする、アクティブマトリクス型発光装置における画素駆動方法。
