Title (EN) CIRCUIT ARRANGEMENT FOR AC DRIVING OF ORGANIC DIODES
(FR) AGENCEMENT DE CIRCUITS DE COMMANDE A COURANT ALTERNATIF DE DIODES ORGANIQUES
Abstract: front page image
(EN)Organic light emitting devices emit light when operated with low dc voltage forward bias. According to the present invention, a space saving circuit arrangement of organic light emitting devices is disclosed, the circuit arrangement emitting light on both the positive and the negative cycle of an ac driving voltage. Furthermore a method is disclosed for producing the circuit arrangement on a substrate. Advantageously, the present invention allows for high voltage ac driving of organic light emitting devices or organic diodes without the need of additional rectifying electronics.
(FR)Les dispositifs électroluminescents organiques émettent de la lumière lorsqu'ils sont exploités avec une polarisation directe d'une faible tension de courant continu. L'invention concerne un agencement compact de circuits de dispositifs électroluminescents organiques qui émet de la lumière pendant les cycles positif et négatif de la tension de commande à courant alternatif. L'invention concerne en outre une méthode de fabrication de l'agencement de circuits sur un substrat. L'invention permet de commander de manière avantageuse avec un courant alternatif de haute tension des dispositifs électroluminescents organiques ou des diodes organiques sans qu'il soit nécessaire d'utiliser des éléments électroniques redresseurs additionnels.
