Abstract (en)

The technique includes formation of all conducting bands in a single layer, with resistances formed in serpentine fashion to provide electrical connections. A series of conducting bands (34R, 34B, 34V) are formed, each carrying the luminophore elements for the three colours. The conducting bands of each of the three sets are connected by interconnecting rails (32R, 32B, 32V), with resistance elements (36R, 36B, 36V) linking each band to its respective rail. The conducting bands and their resistances are formed from the same conductive layer. The bands may be formed in groups, in which case one resistance is provided for the connection of each group. The resistances may be formed by a serpentine conducting track on the substrate, and both the substrate and the resistances are formed of a transparent material. The conducting layer may be an oxide of indium, doped with tin.

Abstract (fr)

Selon l'invention, on forme au moins un ensemble de bandes conductrices (34R, 34B, 34V) portant des bandes d'éléments luminophores et au moins un conducteur d'interconnexion (32R, 32B, 32V) relié aux bandes conductrices par l'intermédiaire de résistances (36R, 36B, 36V). Les bandes conductrices et les résistances sont formées à partir d'une même couche conductrice. L'invention s'applique notamment aux écrans plats à micropointes en couleurs. <IMAGE>
