Abstract

L'invention concerne un dispositif d'affichage à tube à rayon cathodique 1 d'une image de grande surface et tres lumineuse. Il comprend une grille à segments 7 disposée en avant d'un écran fluorescent d'affichage 3, chaque segment de la grille étant adressable séparément pour commander le passage des électrons à travers eux. L'utilisation de la grille à segments permet à l'information affichée d'être modifiée rapidement par application d'un signal de commande de faible puissance. L'invention trouve son application dans l'affichage d'informations destinées à un public nombreux.The invention relates to a cathode ray tube display device 1 of an image of large area and very bright. It comprises a grid with segments 7 disposed in front of a fluorescent display screen 3, each segment of the grid being separately addressable to control the passage of electrons through them. The use of the segmented grid allows the displayed information to be changed quickly by application of a low power control signal. The invention finds its application in the display of information intended for a large audience.
