Abstract
(EN)
Lead is an undesirable element to have present in display panels during the manufacturing process. In addition, the use of lead-bearing glasses presents a potential environmental and personal health problem. A composition for a dielectric ink (50) used in a screening process according to the present invention includes a lead-free glass frit binder, silica and a vehicle. The dielectric composition is particularly suited for use in gas plasma display panels (10). The composition is formulated to provide a multilayer dielectric coating to isolate layers of conductor runs (120) and a mask dielectric coating to provide a low-cost lead-free glass, black insulation layer between conductor runs and the gas plasma.

Le plomb est un élément dont la présence est indésirable dans des panneaux d'affichage pendant le processus de fabrication. En outre, l'utilisation de verres plombifères présente un danger potentiel pour l'environnement et la santé de l'individu. Une composition d'encre diélectrique (50) utilisée au cours d'un procédé de blindage conforme à la présente invention comporte un liant fritté de verre exempt de plomb, de la silice et un véhicule. Cette composition diélectrique est prévue en particulier pour être utilisée dans des panneaux d'affichage (10) à plasma gazeux. Cette composition est élaborée pour offrir un revêtement diélectrique à multicouches afin d'isoler les couches de pistes conductrices (120), ainsi qu'un revêtement diélectrique de masque afin d'obtenir une couche bon marché d'isolation noire en verre exempt de plomb entre les pistes conductrices et le plasma gazeux.
