  • Up to now, one of the most serious problems in AC PDP is low luminous efficiency. One possible candidate for solving such problem is using high density Xe. But an increase of the Xe percentage cause rising of the driving voltage and so even if brightness is being increased, luminous efficiency is decreased. In this study, to solve this problem, we proposed new electrode structure. A test panel fabricated using new electrode shows an improvement of efficiency by 25% and a lowering of sustain voltage by 20% compared with the conventioned structure.

  • This paper proposes a relative lifetime test method of MgO thin film. The suggested test conditions are 5$0^{\circ}C$, 400Torr, 20% over-voltage and 300KHz. The relative lifetime of MgO thin film is significantly affected by the MgO preparing conditions and Xe partial pressure. As result, the lifetime of the AC plasma display panel (PDP) is increased with an MgO thickness of 2000$\AA$ to 8000$\AA$ but is saturated over 5000$\AA$ (up to 9000 $\AA$). In addition, as Xe partial pressure increases, AC PDP lifetime increases.

  • We propose new driving schemes, asymmetry and long gap mode, of PDP having auxiliary electrode between scan and common electrode. For the asymmetric modes, the auxiliary electrode located nearly center of the primary electrodes is connected to the scan of common electrode during all periods of reset, address and sustain. For the long gap mode, it is electrically disconnected or maintained at dc voltage of Vs/2 during sustain period except the first several sustain pulses. The proposed structure and driving method can provide higher luminous efficacy by minimizing consumption energy. The effectiveness of the new driving schemes has been investigated for various Xe partial pressure conditions.
