Abstract (en)
The luminophore material is supported on a resistive layer. The flat anode display screen comprises luminophorescent elements (4R, 4G, 4B) which are intended to be excited by electronic bombardment. These elements are arranged on at least one biasing electrode. The elements form a stack consisting of a resistive layer (8), itself deposited on a conductive layer (5B, 5R, 5G) forming a bias layer for the luminophorescent elements. The luminophore elements may either be deposited directly on top of the resistive layer (8) or they may be deposited on a conducting reflective layer which is itself deposited on the resistive layer.
Abstract (fr)
L'invention concerne une anode d'écran plat de visualisation, comportant des éléments luminophores (4R, 4G, 4B) destinés à être excités par un bombardement électronique, ces éléments étant déposés sur au moins une électrode de polarisation constituée, au moins au droit des éléments luminophores, d'un empilement comprenant une couche résistive (8), elle-même déposée sur une couche conductrice (5B, 5R, 5G) de polarisation des éléments luminophores. <IMAGE>
