— A new driving method for dc plasma display panels is proposed which is characterized by the application of non‐discharge pulses applied to the auxiliary anode. The role of these pulses is to affect the main discharge. This new method shows an enlarged stable operating region and decreased delay time of the sustain pulse compared to a method with no pulses applied to the auxiliary anode. The luminance is increased by 42% and the luminous efficacy by 33%. Non‐discharge pulses with frequencies in the range from 1 kHz to 1 MHz improve the luminance and the luminous efficacy of the display cell. It is found that the optimum distance between the auxiliary anode and the main anode is about 200 μm.
