CA 2256240

A plasma display having a transparent front panel spaced from a back panel which is a metal core having layers of a dielectric material extending over and bonded to the core. Conductive electrodes are on the surface of or imbedded in the dielectric layer of the back panel. The materials of which the back panel is made are chosen to form a back panel having a thermal coefficient of expansion compatible with that of the front panel. Barrier ribs are formed on the back panel by embossing the green tape before cofiring the bonded assembly. The green tape is embossed using pulsed pressure and an embossing tool that is formed by assembling embossing members and spacing members in compression. The embossing tool further includes elastic spacers mounted outside of the embossing tool and in a position such that the elastic spacers are held in compression during the embossing operation to aid in releasing the embossed green tape from the embossing tool after the embossing operation.
