Abstract

La présente invention concerne un substrat d'affichage, un panneau d'affichage, un procédé d'excitation de panneau d'affichage et un dispositif électronique qui appartiennent au domaine technique de l'affichage. Le substrat d'affichage comprend : une base et une couche de définition de pixels disposée sur le substrat, la couche de définition de pixels comprenant une pluralité de parties de définition de pixels, une première électrode, une couche électrochromique et une électrode d'attaque de commande tactile qui sont successivement disposées de manière empilée sur le côté de chaque partie de définition de pixels qui est opposée à la base, et une réaction de changement de couleur pouvant avoir lieu dans la couche électrochromique sous l'action de champs électriques provenant de la première électrode et de l'électrode d'attaque de commande tactile.
