Description
OLEDを使用して製造されるディスプレイは、LCD及び他のフラットパネル技術に対して多くの利点を提供する。それは、明るく、カラフルであり、立ち上がりが早く(LCDに比較して)、広い視野角を提供し、多様な基板上に容易に安く製造することができるというものである。有機(ここでは有機金属を含む)LEDは、使用される材料に応じた色の範囲において、ポリマー、低分子及びデンドリマーを含む材料を使用して製造することができる。ポリマー系有機LEDの例は、WO90/13148、WO95/06400及びWO99/48160に記載されており、デンドリマー系材料の例は、WO99/21935及びWO02/067343に記載されており、いわゆる低分子系装置の例は、US4,539,507に記載されている。
図1cには、上面発光型アクティブマトリックスOLEDディスプレイ100の鉛直断面図が示されている(例示のために、若干簡略化されている)。
図3aは、電圧制御されたOLEDアクティブマトリックス画素回路150の例を示す。回路150がディスプレイの各画素に供給され、接地152、Vss154、行選択124及び列データ126バスバーが画素を相互接続して供給される。したがって、各画素は電力及び接地接続を有し、各行の画素は共通の行選択ライン124を有し、各列の画素は共通のデータライン126を有する。
