Definitions
- a flat screen consists of two generally rectangular external plates, for example in glass.
- a plate constitutes the surface of the screen, while the other forms the background of the screen, for example, provided with means of emission.
- These two plates are assembled by means of a sealing joint, so as to be spaced from each other.
- FED field effect
- VFD fluorescent vacuum display

Description
Claims (5)
- Connexion électrique entre l'espace interne (8) d'un écran plat et l'extérieur au moyen d'une ligne (10) conductrice de faible épaisseur sous-jacente à un joint périphérique de scellement (7) sensiblement plus épais, caractérisée en ce qu'elle comporte une structure ajourée favorisant sa dilatation, ladite structure ajourée est telle que la connexion électrique est dépourvue de tronçon conducteur rectiligne.
- Grille d'écran plat à micropointes constituée de lignes (10) déposées sur une couche (11) isolante revêtant des conducteurs de cathode (9), caractérisée en ce que chaque ligne de grille est pourvue d'au moins une connexion électrique selon la revendication 1.
- Grille selon la revendication 2, caractérisée en ce qu'elle est constituée de chrome.
- Grille selon la revendication 2, caractérisée en ce que chaque ligne (10) est en niobium dans la zone active de l'écran, chaque connexion électrique (32) étant en chrome.
- Écran plat de visualisation du type comportant une cathode (2) à micropointes (3) de bombardement d'une anode cathodoluminescente (5), caractérisé en ce qu'il comprend une grille (4) conforme à l'une quelconque des revendications 2 à 4.
