Abstract :
The wall-voltage loss in PDPs with four different types of protective layers, i.e., undoped MgO, Si-doped MgO, Sc-doped MgO, and MgCaO (15%) plasma, are compared. Using a two-electrode opposed-discharge-type PDP, the change in external panel voltage needed to get a new discharge is measured as a function of the waiting time from 5 μs to 50 ms, the number of sustain cycles (1-1024), and the sustain frequency. The results shows that the wall-voltage loss cannot only be caused by amplified exoemission but that dielectric relaxation effects might also play an important role.
