Abstract

Indicateur de charge léger et fiable. Il comprend un substrat transparent 32, une solution de cristaux liquides 34 adhérant à une partie prédéterminée de la surface arrière de ce substrat, cette solution de cristaux liquides pouvant changer de couleur en réponse à des changements de température compris dans une gamme donnée; une couche de fond noir 38 adhérant au moins à l'arrière de cette solution de cristaux liquides, dans la partie prédéterminée du substrat mentionné ci-dessus; et un adhésif 40 adhérant à cette couche de fond noir, et à toutes les parties du substrat non recouvertes par la couche de fond noir. Application aux chargeurs de batterie.
