Influence of driving frequency on the system parameters in surface discharge of AC plasma display panels

The influence of the driving frequency on the wall charge and voltage is experimentally investigated for the surface discharge of AC plasma display panels. A square pulse with a rising time of 150 ns and a duty ratio of 40% was used in the experiment. It is found that the capacitance C-o of the surface discharge in a gas-filled region is almost constant and is 0.3 pF/cell, whereas the capacitance C-g in the dielectric region is significantly decreased from 7.5 pF/cell to 0.8 pF/cell, as the driving frequency is increased from 10 kHz to 200 kHz. It is also found that both the wall charge and the wall voltage decrease from 34.5 pC/cell to 15.6 pC/cell and from 104.4 V to 76.5 V, respectively, as the driving frequency increases from 10 kHz to 200 kHz.
