    • A plasma display having a transparent front panel (622) spaced from a back panel (610) which is a metal core (612) having layers of a dielectric material (614) extending over and bonded to the core. Conductive electrodes (620) are on the surface of or embedded 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 (TCE) compatible with that of the front panel. The dielectric material is made from a green ceramic tape which is bonded to the core and cofired with the core to form the back panel. Barrier ribs (616) are formed on the back panel by embossing or scribing the green tape before cofiring the bonded assembly. Slight differences in the TCEs of the front and back panels may be compensated for by heating the panel having the lower TCE to a temperature hotter than the panel having the higher TCE during the frit seal process. Alternatively, the materials for the dieletric (614) may be chosen such that the composite TCE of the cofired assembly (610) matches the TCE of the front panel.
    • 一种等离子体显示器,其具有与背板(610)间隔开的透明前面板(622),所述后面板是金属芯(612),其具有延伸并结合到所述芯的电介质材料层(614)。 导电电极(620)位于背板的介质层的表面或嵌入其中。 选择制造后面板的材料以形成具有与前面板的热膨胀系数(TCE)兼容的热膨胀系数(TCE)的后面板。 介电材料由绿色陶瓷带制成,其粘结到芯并与核共烧以形成后面板。 阻挡肋(616)通过在烧结粘结组件之前对生带进行压花或划线而形成在后面板上。 在玻璃料密封过程中,通过将具有较低TCE的面板加热至比具有较高TCE的面板的温度更高的温度,可以补偿前面板和后面板的TCE的微小差异。 或者,可以选择用于模具(614)的材料,使得共烧组件(610)的复合材料TCE与前面板的TCE匹配。
