  • This paper describes a new method to decide the margin for the sustain voltage of AC PDPs based on the wall-charge distribution. We model the discharge cell and measure the wall-charge when sustain pulses are applied to the AC PDP. The measured wall-charge distribution informs us of the voltage forming the maximum wall-charge which should be chosen as the sustain voltage.

  • In this study, a new processing route of barrier ribs for the plasma display panels was attempted. A slurry containing ceramic powders for the barrier ribs, binder, hardener, and other additives, was molded into a PDMS mold by capillary infiltration process. The molded slurry was cured prior to mold removal. It was demonstrated that the process can fabricate successfully the cell type barrier ribs of PDP.

  • 본 연구에서는 새로 고안된 DC방전 AND gate를 구성하는 각 방전셀 상호간의 영향을 방전특성 측면에서 규명하였다. 4개의 각 셀은 서로 공간전하와 결합하여 깊은 연관이 있었으며 그 결과 PDP의 address 방전을 도와주기 위한 프라이밍 방전의 동작마진을 얻기가 매우 어렵다는 것을 정성적으로 알았다. 실험결과 각 전극의 최적화된 방전전압을 결정할 수 있었다.

  • Tin doped indium oxide(ITO) and Al doped zinc oxide(ZnO:Al) films, which are widely used as a transparent conductor in optoelectronic devices, were prepared by using the capacitively coupled DC magnetron sputtering method. ITO and ZnO:Al films with the optimum growth conditions showed each resistivity of $1.67{\times}10^{-3}[{\Omega}-cm],\;2.2{\times}10^{-3}[{\Omega}-cm]$ and transmittance of 89.61[%], 90.88[%] in the wavelength range of the visible spectrum. The two types of 5 inch-PDP cells with ZnO:Al and ITO transparent electrodes were made under the same manufacturing conditions. The PDP cell with ZnO:Al film was optimally operated in the mixing gas rate of Ne(base)-Xe(8[%]), and at gas pressure of 400[Torr]. It also shows the average measured brightness of $836[cd/m^2]$ at voltage range of $200{\sim}300$[V]. Luminous efficiency, one of the key parameter for high brightness and low power consumption, ranges from 1.2 to 1.6[lm/W] with increasing frequency of ac power supplier from 10 to 50[Khz]. The brightness and luminous efficiency are lower than those with ITO electrode by about 10[%]. However, these values are considered to be enough for the normal operation of PDP TV.

  • Effects of delay on the discharge time lag and the controllability of weak discharge mode were studied under single cell driving circumstances of ac PDP. It was found that sufficient number of priming particle is necessary for inducing weak discharge in ramp voltage driving. Discharge time lag was reduced dramatically under priming condition. It is speculated that the increasement of strong discharge is related to the reduction of the $Xe^*(^3P_1)$ particles during the after glow.

  • Unstable sustain discharges can occur at the bottom cells of the panel at high temperature. To solve this problem, the wall charge variation during an address period was investigated. A test panel of 7.5 inch XGA level was used and one green cell was measured. In order to realize operating condition equal to that of the bottom cells of 50 inch panel, the addressing stress pulses are applied. It seems that the resultant wall charge loss during address period increased with increase of stress time, temperature, pressure and Xe %. Wall charge loss increases with potential difference between scan electrode and address electrode, therefore wall charge loss can be minimized by the increase of scan voltage during address period.

  • We studied the dependence of the electrical characteristics of MgO protecting layer on temperature in an AC PDP cell. Careful measurements of the surface resistance of MgO were performed for the temperature range from room temperature to $100^{\circ}C$ with and without the VUV illumination. Experimental results show that the resistivity is affected by not only the temperature but also VUV irradiation. The measurement of wall charge distribution and the address discharge delay time as to the temperature show that the resistivity change of MgO may affect the wall voltage and consequently the discharge delay time.
