Abstract
The invention concerns a method for producing on a plasma panel faceplate, a dielectric coating comprising embossed patterns. The invention is characterized in that a vitreous coat is produced on the plasma panel faceplate; a mould bearing embossed patterns is applied on the vitreous coat, then the faceplate and the mould are heated until a creep effect of the vitreous coat is obtained which causes the latter to match the form of the mould, thereby enabling to produce simultaneously and with improved quality with respect to prior art, a dielectric coating bearing embossed patterns such as for instance barriers. The invention is particularly applicable to alternating plasma panel.
