Discharge Characteristics of MgO in Ne for Liquid Crystal Display Back-lighting Electrode

Abstract

Application of MgO to electrodes of the liquid crystal display back-lighting source was investigated. The breakdown voltages in the case of MgO electrodes were measured under various Ne pressures with a V-Q Lissajous method. In order to measure the breakdown voltages in Ne, the samples tested were MgO single crystal plates of polished surface and non-polished surface, and MgO sintered ceramic plates. The breakdown voltage in the case of MgO single crystal plates of non-polished surface was lower than that in the case of MgO single crystal plates of polished surface. The breakdown voltage in the case of MgO sintered ceramic plates was slightly lower than that in the case of MgO single crystal plates of non-polished surface.
