Lanthanum hexaboride (LaB) thin films were used as protective layers in alternating current plasma display panels (AC-PDPs). The firing voltages and discharge delay time of protective LaB thin films were evaluated and compared with the conventional protective MgO layers in planar-type test panels filled with 5%-15% Ne-Xe. By employing LaB thin films as protective layers, both the firing voltages and discharge delay time decreased drastically. Improvements in the discharge properties of the LaB thin film could be attributed to the lower work function, offering more priming electrons during the discharge process. [ABSTRACT FROM AUTHOR]
