A high efficacy AC PDP with an auxiliary electrode was investigated with the aim of attaining a better understanding of the discharge mechanism in a display cell. There are three types of discharge modes in an AC PDP with an auxiliary electrode; however, only two discharge modes that can decrease the discharge current are recommended for use in a high efficacy AC PDP. The discharge current decreased as the auxiliary pulse voltage increased because the wall charges on the sustain electrode were erased. However, the IR intensity did not decrease as the auxiliary pulse was applied. It was also found that the auxiliary pulse provides priming particles for the following periodic sustain pulse discharge. Consequently, there is a decrease in the discharge current without a reduction of the luminance and priming particles due to the auxiliary pulse. This can enhance the excitation rate of the discharges generated in the display cell of an AC PDP with an auxiliary electrode.
