Abstract

La présente invention porte sur un panneau (100) d'affichage, comprenant une zone (10a) d'affichage et une zone (10b) de non affichage ; et au moins une puce (40) électroluminescente et un circuit (100) de commande qui sont agencés dans la zone (10b) de non affichage. Le circuit (30) de commande est connecté à ladite puce (40) électroluminescente et est utilisé pour la commande de la luminance ou de la non luminance de ladite puce (40) électroluminescente. Du fait qu'une source lumineuse comprend le panneau (100) d'affichage, l'aide d'une source lumineuse externe n'est pas nécessaire, de telle sorte que le volume d'un module de rétroéclairage peut être réduit.
