Abstract

La présente invention concerne un module intégré intégrant un écran AMOLED doté d'un panneau solaire et un dispositif électronique appliquant un tel module intégré. Le module intégré comprend une partie d'écran AMOLED transparent, une partie de photopile et un substrat transparent partagé. Le dispositif électronique comprend en outre une partie de gestion de courant destine à gérer et à distribuer le courant électrique provenant du module intégré, une batterie principale du dispositif électronique ou une alimentation extérieure du dispositif électronique. Dans le module intégré et le dispositif électronique appliquant un tel module intégré, la partie de photopile et la partie d'écran AMOLED partagent le même substrat, ce qui permet de réduire l'épaisseur totale et la taille du dispositif électronique. La partie d'écran AMOLED présente une caractéristique à auto-émission et ne peut être affectée par la partie de photopile, ce qui permet de garantir la qualité de l'écran.
