  • The MgO protective layer provides protection from the discharge, lowers the discharge voltage and prolongs the AC-PDP lifetime. We have investigated the characteristics of degradation of MgO protective layer, which correlates to the image-sticking[1] and the lifetime in AC-PDP. The degraded MgO have been changed the surface morphology of MgO. It was found that panel lifetime depended on degradation of MgO protective.

  • The improvement of luminance and luminous efficiency is the one of the most important parts in AC-PDPs. To achieve high luminance and luminous efficiency, high VUV emission efficiency is needed. We measured the emission spectra of the vacuum ultraviolet(VUV) rays in surface discharge AC-PDP with ternary gas mixture of He-Ne-Xe. The influence of He-Ne-Xe gas-mixture ratio on excited $Xe^{\ast}$ resonant atoms and $Xe_2\;^{\ast}$ dimers has been investigated. It is found that luminous efficiency of ternary gas mixture, He-Ne-Xe, is shown to be much higher than that of binary gas mixture of Ne-Xe. For improving discharge luminous efficiency, we have studied VUV emission characteristics of ternary gas mixture, He(50%)-Ne-Xe and He(70%)-Ne-Xe with Xe concentration and filling gas pressure.

  • A new AC-PDP driving method was proposed to reduce the address period. The overlapped scan method can reduce the address period. However, this method has a narrow address voltage margin compared with conventional scan method in this paper, Slope overlapped scan method is presented. The proposed new overlapped scan method allows wider address voltage margin than conventional overlapped scan method.

  • Transparent ac-PDP test panel was prepared via a combination of materials including ITO sustaining electrodes, thin film dielectric layer and nano-sized phosphor powders. The thin film dielectric layer was prepared by E-beam evaporation process and phosphor layer was deposited on metal mesh pattern by electrophoretic deposition process. The optical transmittance and luminance of the panel indicated that full color transparent ac-PDP is feasible with the approach.

  • The relationship between the discharge aging time and the superficial layer thickness of MgO thin film was investigated in an AC PDP. The discharge characteristics of an AC PDP with the various aging time were evaluated by discharge aging experiments. We find the presence of a superficial lay which is related to the discharge characteristics during aging process. The superficial layer of MgO thin film was observed by Transmission Electron Microscope (TEM). It was found that the superficial layer thickness of MgO was dependent on discharge aging time.

  • AC-PDP의 구동은 인가되는 Pulse의 파형에 의하여 결정된다. 이번 실험은 AC-PDP의 Subfield 파형중 Sustain 부분 첫 번째 Pulse의 폭(Width)에 변화를 주어 다음 Suatain Pulse 기간동안의 전기 광학적 특성을 구속 카메라와 전류의 변화를 통하여 측정하였으며 Sustain Pulse의 Rising Time을 변화 시켜 방전특성을 측정하였다. 이를 통하여 적합한 Sustain 구간의 초기조건을 예측하였으며, 적합한 Sustain Pulse를 찾아가는 실험 방법을 찾고자 하였다.

  • We applied the Atmospheric Pressure Plasma (AP-plasma) to the MgO film to try to control the Aging-time on the PDP production-line. The MgO film surface and the discharge characteristics of AC-PDPs were investigated, using the plasma-treated MgO film. The Aging-time change can be achieved by treating the MgO film with plasma. This method can be adapted to the mass production-line.
