Title (EN) AN ELECTROLUMINESCENT DISPLAY DEVICE
(FR) AFFICHEUR ELECTROLUMINESCENT
Abstract:
(EN) A drive of a display device based on polymer LEDs, for example pixels arranged in the form of a matrix, in which the lifetime is increased by writing the information from an interlaced signal each time into two successive rows. The driving may be based on voltage control at which voltages across the pixels define the picture to be displayed, but may alternatively be based on current control.
(FR) L'invention a trait à une commande d'afficheur dans laquelle on utilise des diodes polymères luminescentes, par exemple, des pixels disposés en matrice, dont on accroît la durée utile en écrivant à chaque fois dans deux rangées successives les informations provenant d'un signal entrelacé. Cette commande, qui peut s'articuler autour d'une commande de tension dans laquelle des tensions appliquées aux bornes des pixels définissent l'image à afficher, peut également dépendre d'une commande d'intensité de courant.
