Abstract

L'invention concerne un dispositif d'affichage. Le dispositif d'affichage comprend : un boîtier ayant une surface et présentant un espace interne ; un cadre faisant face à la surface et divisant l'espace interne en un premier espace et un second espace ; un module d'affichage situé dans le premier espace et faisant face à la surface ; une plaque faisant face au cadre, divisant le second espace en un premier sous-espace et un second sous-espace, et comportant une pluralité de trous qui permettent une communication entre le premier sous-espace et le second sous-espace ; et un ventilateur servant à faire circuler de l'air vers ce premier sous-espace et ce second sous-espace.
