Abstract

Cette invention concerne un dispositif de commande et un procédé de commande pour un rétro-éclairage d'un panneau d'affichage de réfrigérateur. Le dispositif comprend un panneau de commande relié au rétro-éclairage et un capteur de détection de distance pour détecter la distance entre un corps humain pénétrant dans une zone de détection et le réfrigérateur. Le capteur de détection de distance est relié au panneau de commande qui commande la mise en tension/hors tension du rétro-éclairage en fonction des signaux issus du capteur de détection de distance. Le procédé selon l'invention comprend les étapes consistant à : détecter la distance entre le corps humain qui pénètre dans la zone de détection et le réfrigérateur en utilisant le capteur de détection de distance ; commander la mise en tension/hors tension du rétro-éclairage au moyen du panneau de commande en fonction des signaux issus du capteur de détection de distance. L'utilisation du capteur pour détecter la distance entre un corps humain et le réfrigérateur, et pour commander ainsi la mise en tension/hors tension du rétro-éclairage, permet aux utilisateurs d'observer les informations affichées sur le panneau d'affichage sans toucher ou manipuler un panneau écran d'affichage.
