Abstract

Une pluralité d'unités consistant chacune en trois diodes électroluminescentes de couleur rouge, vert jaunâtre et bleu, par exemple, sont disposées en les serrant les unes contre les autres de manière à former un treillis, et une impulsion électrique sérielle d'intensité et de largeur variables est appliquée à chaque diode électroluminescente de manière à réguler l'intensité de l'émission lumineuse et à faire varier les couleurs émises. Dans ce dispositif les diodes peuvent être disposées en les serrant les unes contre les autres sur un côté et une interconnexion multicouche peut être formée sur un substrat isolant flexible par dépôt sous vide ou par placage. Cet agencement permet d'enrouler la surface d'affichage, ce qui est impossible avec les dispositifs d'affichage conventionnels.
