Abstract

L'invention concerne une électrode-grille. Elle comprend une grille 3 en plusieurs parties situées dans un même plan, isolées les unes des autres et fixées à une plaque de support 1 à l'aide d'un composé réfractaire 4 renfermant des particules plus grandes que le pas de la grille. Ces particules servent à espacer la grille de la plaque de support, facilitant ainsi sa fabrication. L'invention trouve son application dans des tubes d'affichage à rayon cathodique.
