Characteristics of a micro dielectric barrier discharge ignited by a cold cathode with high ion-induced secondary electron emission for plasma display panel

We present here measurements of plasma display panel PDP ignited by SrO and SrCaO cold cathodes with high yield of ion-induced secondary electron emission high i . SrOand SrCaO-cathode PDPs attain high luminous efficacy at low applied voltage, where the breakdown voltage is 30% lower than that of ordinary MgO-cathode PDP. Current and emission measurement clearly demonstrates that SrOand SrCaO-cathode PDPs operated at low voltage realize a discharge with smaller current flow and lower electron energy, which are considerably appropriate for high luminous efficacy of PDP. Simulation analysis shows the effect of the highi cathode on the luminous efficacy of PDP. A discharge ignited by the highi cathode realizes high electron heating efficiency due to the abundant seed electrons from the highi cathode, resulting in high luminous efficacy of PDP. © 2009 American Institute of Physics. doi:10.1063/1.3253723
