Abstract: front page image
(EN)Conventionally, it has been difficult to display a favorable image by using an organic EL display panel. An EL display, according to the invention, comprises EL elements (15) arranged in a matrix, driving transistors (11a), and drive circuit means. The drive circuit means has a voltage gradation circuit (1271) for generating a program voltage signal, a current gradation circuit (164) for generating a program current signal, and switches (151a, 151b) for switching between the program voltage and current signals. The drive circuit is adapted to apply signals to the driving transistors (11a).
(FR)Il et généralement difficile d'afficher une image avantageuse au moyen d'un écran EL organique. L'afficheur EL de l'invention comprend des éléments EL (15) disposés en matrice, des transistors d'excitation (11a) et un moyen formant circuit d'excitation. Le circuit d'excitation possède un circuit de gradation de tension (1271) conçu pour générer un signal de tension de programme, un circuit de gradation de courant (164) conçu pour générer un signal de courant de tension, et des commutateurs (151a, 151b) conçus pour assurer la commutation entre des signaux de tension de programme et des signaux de courant. Le circuit d'excitation est conçu pour appliquer des signaux sur les transistors d'excitation (11a).
(JA)有機EL表示パネルを利用して良好な画像表示を得ることが困難であった。マトリックス状に配置されたEL素子15および駆動用トランジスタ11aと、プログラム電圧信号を発生する電圧階調回路1271、プログラム電流信号を発生する電流階調回路164、およびプログラム電圧信号とプログラム電流信号との切り換えを行うスイッチ151a、151bを有する、駆動用トランジスタ11aに信号を印加するドライブ回路手段とを具備した、EL表示装置である。
