Abstract

The secondary electron emission properties of MgO for liquid crystal display backlighting electrodes were investigated. The breakdown voltages for MgO electrodes were measured under various Ne pressures by the V-Q Lissajous method. To measure the breakdown voltages of MgO, the samples tested were MgO single crystal plates with polished surface and non-polished surface and MgO sintered ceramic plates. The breakdown voltage for MgO single crystal plates with non-polished surface was lower than that with polished surface. The breakdown voltage for MgO sintered ceramic plates was slightly lower than that for MgO single crystal plates with non-polished surface. The secondary electron emission properties were affected by the surface roughness of the MgO plate.
