Abstract

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.

Figure imgaf001
The invention relates to a flat screen with microtips comprising a cathode (1) provided with active areas of electron emission micropoints (2); a cathodoluminescent anode (5) provided, at least opposite said active zones of microtips, with active areas of phosphor elements (16); a main electron extraction grid (3) emitted by the active microtips (2) towards the phosphor elements (16); and, on the cathode side (1), at least one micropoint sacrificial zone (2 ') capable of being addressed, out of periods of operation of the screen and independently of said active zones.
