Abstract

L'invention concerne un circuit de pixel et son procédé d'attaque, ainsi qu'un panneau d'affichage et un appareil d'affichage. Le circuit de pixel comprend un premier circuit d'attaque et un second circuit d'attaque. Le premier circuit d'attaque est conçu pour générer, en fonction d'un signal de données, un premier courant d'attaque qui commande un premier élément électroluminescent pour qu'il émette de la lumière, et le second circuit d'attaque est conçu pour générer, en fonction d'un signal de commande, un second courant d'attaque qui commande un second élément électroluminescent pour qu'il émette de la lumière. Le signal de commande est obtenu en fonction du signal de données et il est différent du signal de données.
