Abstract

L'invention concerne un affichage flexible, une unité anti-contrefaçon et un dispositif associé. L'affichage flexible comprend une nano-alimentation de génération électrique (61) et un panneau d'affichage flexible (63). La nano-alimentation de génération électrique (61) est connectée au panneau d'affichage flexible (63) pour fournir l'énergie au panneau d'affichage flexible (63) en transformant l'énergie mécanique en énergie électrique. La nano-alimentation de génération électrique (61) comprend un nano-générateur (611). Le panneau d'affichage flexible (63) procède à l'affichage au moyen de l'énergie électrique de la nano-alimentation de génération électrique (61). Du fait que la nano-alimentation de génération électrique (61) fournit l'énergie à l'affichage, l'affichage peut fournir lui-même l'énergie sans avoir besoin de connecter d'alimentation électrique externe ni de batterie, ce qui permet de produire un affichage entièrement flexible. L'affichage flexible peut s'appliquer à un sac à main, une capsule de bouteille, une carte à puce, une unité anti-contrefaçon et un dispositif utilisant l'unité anti-contrefaçon, etc.
