Abstract

Un dispositif d'affichage à tubes émettant de la lumière plasmatique est formé par un module de tubes émettant de la lumière plasmatique d'une taille plus petite que la taille d'un écran du dispositif d'affichage à tubes émettant de la lumière plasmatique et inclut un récipient pour contenir une pluralité de modules à tubes émettant de la lumière plasmatique et une unité de déplacement pour disposer les modules à tubes émettant de la lumière plasmatique dans le récipient. Les modules à tubes émettant de la lumière plasmatique disposés sur l'unité de déplacement sont reliés les uns aux autres de façon à former un dispositif grand écran à tubes émettant de la lumière plasmatique. En conséquence, lors du transport du dispositif, celui-ci peut être contenu dans une taille correspond au module à tubes émettant de la lumière plasmatique, ce qui facilite le transport et évite les dommages sur l'écran.
