Abstract (en)
The screen includes a cathode (1) with electron emitting points (2) and a grating (3) with holes (4) corresponding to the emitting points. The cathode is placed opposite an anode with photoluminiscent surface on a glass substrate (6). The emitting points are deposited along conductors (7) which are organised in columns. The grating has rows normal to the direction of the columns. An insulating layer is provided between the grating and the cathode. A vacuumed space (11) is provided between the anode and the cathode which are separated by spacers. An electronic circuit (12) controls the cathode and the anode,
Abstract (fr)
L'invention concerne un écran plat à micropointes comportant une cathode (1) pourvue de zones actives de micropointes (2) d'émission électronique ; une anode (5) cathodoluminescente pourvue, au moins en regard desdites zones actives de micropointes, de zones actives d'éléments luminophores (16) ; une grille principale (3) d'extraction d'électrons émis par les micropointes actives (2) en direction des éléments luminophores (16) ; et, côté cathode (1), au moins une zone sacrificielle de micropointes (2') propre à être adressée, hors de périodes de fonctionnement de l'écran et indépendamment desdites zones actives. <IMAGE>
