Abstract

La présente invention concerne un écran à plasma (1) comportant des premières et des deuxièmes électrodes (X, Y) qui définissent des interruptions de charge de surface (60) correspondant à des lignes d'affichage (L1-L3), s'étendent dans une première direction et sont placées en parallèle selon des lignes impaires (L1, L3) et des lignes paires (L2) disposées dans des ordres différents, ainsi que plusieurs troisièmes électrodes (A) qui s'étendent dans une seconde direction. Les deuxièmes électrodes (Y) et les troisièmes électrodes (A) constituent une matrice d'électrodes conçue pour sélectionner une cellule et plusieurs cellules (51, 52, 53) correspondent à des points d'intersection de la matrice d'électrodes. L'écran à plasma comporte également des cloisons de séparation de type treillis (23) conçues pour attribuer un espace rempli de gaz aux cellules. Les premières et les deuxièmes électrodes (X, Y) recouvrent partiellement des espaces de décharge (31) pour leurs cellules correspondantes et des parties de cloison horizontales (25) des cloisons de séparation (23). Une dimension (Dy) dans la seconde direction d'une partie recouvrant les espaces de décharge (31) dans les deuxièmes électrodes (Y) est supérieure à une dimension (Dx) dans la seconde direction d'une partie recouvrant les espaces de décharge (31) dans les deuxièmes électrodes (Y).
