Abstract

　有機ＥＬパッシブマトリックス素子の点灯させない区間をハイインピーダンスにする駆動方法において、輝度低下及び輝度ムラを低減した有機ＥＬパッシブマトリックス素子の駆動装置及びその方法を提供する。カラムドライバ（２１）の各駆動部は、各プッシュプル出力に遅延回路（２２－１～２２－３）、差動回路（２３－１～２３－３）及び電流注入回路（２４－１～２４－３）を加えたものからなる。遅延回路（２２－１～２２－３）は、積分回路で代表されるもので、陽極の電圧を所定時間遅らせて平均化する。差動回路（２３－１～２３－３）は、遅延回路（２２－１～２２－３）の出力と元の陽極の電圧との差分を出力する。電流注入回路（２４－１～２４－３）は、この差分の量に応じた量の補充電流Ｉｃを主電流Ｉに加えて陽極に注入する。
