P‐70: New Long Gap Discharge Mode Driven by Low Sustain Voltage for Highly Efficient Plasma Displays

This paper proposes a new long gap discharge mode with a long gap of 400 μm driven by a low sustain voltage (< 200 V) for a highly efficient three‐electrode alternate current plasma display panel (ac‐PDP). Two different types of long‐gap discharge modes can be created depending on the voltage distribution among the three electrodes: a forward long gap discharge mode (FLGDM) with a high sustain voltage where the discharge is initiated from the voltage‐supplied electrode, and a reverse long gap discharge mode (RLGDM) with a low sustain voltage where the discharge is initiated from the ground electrode. As such, in the current study, a highly efficient discharge mode in a long gap was efficiently constructed under a low sustain voltage by properly controlling the amplitude and width of the auxiliary short pulse applied to the address electrode, resulting in a reverse long gap discharge mode with a high efficiency of 2.5 lm/W at a sustain voltage of 170 V.
