Abstract

La présente invention concerne un réfrigérateur comprenant un afficheur transparent et son procédé de commande. Lorsqu'un utilisateur est en contact avec un capteur de contact pour une durée préétablie ou plus, un afficheur devient transparent. Lorsque le contact disparaît ou qu'une porte est ouverte, l'afficheur devient non transparent. Pendant ce temps, même lorsque l'utilisateur effectue une entrée par coulissement ou une entrée par cognement sur le capteur de contact, l'afficheur peut devenir transparent ou non transparent. L'intention d'un utilisateur qui souhaite voir l'intérieur du réfrigérateur peut être discernée de manière précise par le biais d'une action active telle qu'un contact. Ainsi, la présente invention empêche que l'afficheur ne soit inutilement commuté pour être transparent.
