Title
(EN) FLAT DISPLAY SCREEN WITH HIGH VOLTAGE BETWEEN ELECTRODES
(FR) ECRAN PLAT DE VISUALISATION A HAUTE TENSION INTER-ELECTRODES
Abstract
(EN)
Flat display screen of the type comprising a cathode (1) provided with microtips (2) for electron bombardment associated with a grid (3), an anode (5) carrying phosphorescent elements (7) and a space (12) separating the electrodes. The screen comprises an insulating plate (13) defining said space (12) associated with means spacing apart the plate (13) from the anode (5), the plate (13) comprising holes (14) corresponding to the areas (17) provided with microtips (2).
(FR)
L'invention concerne un écran plat de visualisation du type comportant une cathode (1) à micropointes (2) de bombardement électronique associé à une grille (3), une anode (5) portant des éléments luminophores (7), et un espace inter-électrodes (12); écran qui comporte une plaque isolante (13) de définition dudit espace (12) associée à des moyens pour maintenir cette plaque (13) à distance de l'anode (5), ladite plaque (13) étant munie de trous (14) au droit de zones (17) de micropointes (2).
