Title (EN) LUMINOUS PANEL DISPLAY DEVICE
(FR) DISPOSITIF D'AFFICHAGE A PANNEAU LUMINEUX
Abstract:
(EN) A gas discharge display apparatus (10) in the form of an electroluminescent gas filled panel adapted for quickly and inexpensively making a durable and robust luminous sign using image patterns transferred to the panel by painting, silkscreening, stencilling, lithography, or the like. The apparatus generally includes a pair of substantially parallel spaced apart rigid plates, or sheets (12 and 14), enclosing an electroluminescent gas, and having variously located and kinds of conductive elements, such as surface coatings (26 and 28), used as electrodes for energizing the enclosed electroluminescent gas.
(FR) Un appareil d'affichage à décharge de gaz (10) sous forme d'un panneau électroluminescent rempli de gaz est adapté pour réaliser de manière rapide et peu coûteuse une enseigne lumineuse robuste et durable dans laquelle des dessins d'image sont transférés au panneau par les techniques de peinture, sérigraphie, lithographie et analogues. L'appareil comporte en général deux plaques ou feuilles rigides (12, 14) espacées de manière sensiblement parallèle, renfermant un gaz électroluminescent et comportant divers éléments conducteurs disposés à différents endroits, par exemple des couches superficielles (26 et 28), qui servent d'électrodes pour exciter le gaz électroluminescent contenu dans ledit appareil.
