Abstract

画素回路（１０）内のスイッチ用ＴＦＴ（１２，１３）をオン、スイッチ用ＴＦＴ（１４）をオフさせて、駆動用ＴＦＴ（１１）の閾値電圧に応じた電圧（ＶＤＤ＋Ｖｘ）をデータ線（Ｓｊ）に出力し、ソースドライバ回路のスイッチ（２１，２２）をオンさせて、コンデンサ（２６）に、電圧（Ｖｘ）を保持する。次にスイッチ用ＴＦＴ（１３）をオフし、スイッチ（２１～２４）の状態を切り替えて、データ線（Ｓｊ）に電圧（Ｖｄａｔａ＋Ｖｘ）を印加する。さらにスイッチ用ＴＦＴ（１２）をオフ、スイッチ用ＴＦＴ（１４）をオンさせ、有機ＥＬ素子（１５）に駆動用ＴＦＴ（１１）のゲート端子電圧（Ｖｄａｔａ＋Ｖｘ）によって定まる電流を供給する。これにより、画素回路（１０）の規模を増大させずに、データ電圧の振幅を効率よく利用し、駆動用ＴＦＴ（１１）の閾値電圧のばらつきを高い精度で補償する。
