Title
(EN) FLAT-PANEL MATRIX-TYPE LIGHT EMISSIVE DISPLAY
(FR) DISPOSITIF D'AFFICHAGE A EMISSION LUMINEUSE DU TYPE A MATRICE ET A ECRAN PLAT
Abstract
(EN)
A flat-panel matrix-type visible light emissive display (10) has an electron source (20) positioned at the back panel (14) for providing electrons. An electron gating grid (30) having a number of conductive filaments (32) is positioned before the front panel (18) and exposed to the electron source. A display array (30) with a number of parallel conductive phosphor stripes (36) for generating visible radiation when bombarded with electrons is arranged between the electron gating grid and the front panel. A control unit (48) applies an accelerating voltage (V3) to the conductive phosphor stripes (36), and another control unit (44) selectively applies a blocking voltage (V2) and a gating voltage (V1) to the conductive filaments (32).

Dispositif d'affichage (10) à émission lumineuse du type à matrice et à écran plat, comportant une source d'électrons (20) située au niveau du panneau arrière (14) et fournissant des électrons. Une grille de porte d'électrons (30) présentant un certain nombre de filaments conducteurs (32) est positionnée devant le panneau avant (18) et exposée à la source d'électrons. Un réseau d'affichage (34) comportant un certain nombre de bandes de phosphore conductrices parallèles (36) générant un rayonnement visible lorsqu'elles sont bombardées par des électrons est agencé entre la grille d'électrons et le panneau avant. Une unité de commande (48) applique une tension accélératrice (V3) aux bandes de phosphore conductrices (36), et une autre unité de commande (44) applique sélectivement une tension de blocage (V2) et une tension de déclenchement (V1) aux filaments conducteurs (32).
