Abstract

L'invention concerne un spot plat possédant des électrodes à inhibition diélectrique, à savoir des cathodes (12, 15) et des anodes (8; 9a) qui se présentent sous forme de bandes et sont alternées sur la paroi de l'enceinte à décharge (14). Ce spot plat présente entre les cathodes (12; 12, 15) voisines respectivement une anode (9b) supplémentaire, c'est-à-dire qu'une paire d'anodes (9) est respectivement placée entre les cathodes (12; 12, 15). Les cathodes (15) possèdent des protubérances (28) en forme de lobes, qui font face respectivement aux anodes (8) voisines. Ces protubérances sont de plus en plus rapprochées vers les bords (26, 27) du spot plat. En variante ou de façon complémentaire, les deux bandes anodes (9a; 9b) de chaque paire d'anodes sont élargies d'un côté, celui faisant face à la bande correspondante (9b ou 9b). Grâce à ces mesures, la luminance surfacique du spot plat (13) est largement constante jusqu'aux bords (26, 27, 29, 30).
