  • A relationship between discharge delay time and the aging method were investigated: A-Y (Address electrode - Scan electrode) aging and conventional X-Y(Common electrode - Scan electrode) aging with the variation of sustain voltage beyond self-erasing discharge. Although A-Y aging decreases discharge delay time, it has several drawbacks like non-uniformity of discharge, degradation of luminous efficiency and a color temperature. In a conventional aging condition which is carried out near the mid-margin voltage, discharge delay time is short in low voltage and high frequency condition. As an alternative to conventional voltage aging, high voltage aging is suggested which is carried out at self-erasing sustain voltage region. High voltage aging shows lower discharge delay time and fast aging speed than conventional voltage aging.

  • 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.

  • In order to achieve high efficiency and low cost, new high-speed addressing method is suggested. This can be achieved by reducing the address discharge delay time through the priming effect. This paper suggests a new ADR (Address During Reset) driving method which provides priming particles by using a separated driving method without adding auxiliary electrode or auxiliary discharge. The experimental results show an approximately loons reduction in the formative delay time of address discharge and a reduction in jitter of over 200ns. Also, due to enough time being available for reset, there was a reduction in light emitted during reset of about 29% which improved the dark contrast ratio considerably.

  • The effects of the MgO fabrication process on the properties of AC-PDPs were examined. MgO films were deposited by e-beam evaporation with various substrate temperatures and oxygen flow rates. MgO films were analyzed by XRD, CL and ellipsometer. Panel properties such as luminance, efficiency, discharge voltage and discharge delay time were measured with test panels. MgO films with higher temperature, smaller oxygen flow rate showed shorter discharge delay time. Also they showed smaller XRD peak intensity. These results revealed that the discharge delay time was strongly influenced by temperature and oxygen flow rate of the MgO fabrication process.

  • The characteristics of write discharge were investigated when the conventional driving method with the unipolar sustain voltages, and the single sustain driving method applying the bipolar sustain voltage were applied in an AC plasma display. In the case of having a single sustain waveform, the strength of the write discharge is weakened compared to the conventional driving method during the address period, because the wall charge inside the panel is more dissipated by the lower scanning voltage. In the driving method with a single sustain waveform, the bias voltage of the other electrodes was changed to improve the write discharge characteristics. As a result, the intensity of the discharge was enhanced by 32% and the delay time was shortened by 60 ㎲.

  • The most of faults in gas insulation of power facilities are caused by partial discharge. Therefore we simulated partial discharge and measured the radiated electromagnetic wave emitted from partial discharge in the $SF_6$ gas by biconical antenna. This paper describes time delay characteristics of radiated electromagnetic waves with distance between antenna and discharge source.

  • This paper is concerned with an accurate delay time modling of the ED MOS logic gates and its application to the multiple delay logic simulator. The proposed delay model of the ED MOS logic gate takes account of the effects of not only the loading conditions but also the slope of the input waveform. Defining delay as the time spent by the current imbalance of the active inverter to charge and discharge the output load, with respect to physical reference levels, rise and fall model delay times are obtained in an explicit formulation, using optimally weighted imbalance currents at the end points of the voltage transition. A logic simulator which uses multiple rise/fall delays based on the model as decribed in the above has been developed. The new delay model and timing verification method are evaluated with repect to delay accuracy and execution time.

  • The effects of addition of $D_2$ to conventional gases [Ne-Xe and He-Ne-Xe] on the discharge characteristics were investigated in this work with the aim of improving the voltage margin, the wall charge and the jitter. The addition of an extremely small gas-inlet amounts of $D_2$ increased the number of electrons which improves. the $Xe^*$ density and $Xe_2^*$ density. As a result, the voltage margin, the jitter and the wall charge increased.

  • In this paper, we suggest a new driving waveform for stable address discharge in AC PDP without the reduction of contrast ratio. To analyze the influence of cross-talk between discharge and non-discharge cells and verify that proposed waveform shows a stable address discharge, we measured the address discharge delay time. The proposed waveform shows the reduction of the cross-talk and concurrently the improvement of address voltage margin compared with those of selective reset waveform having one reset period in 1TV-Field..

  • 본 연구에서는 기체방전관의 과전압 보호 성능과 수명에 미치는 절연파괴 특성을 알아보기 위하여 황동전극을 이용하여 기체방전관을 제조하였다. 황동전극을 이용한 기체방전관의 절연파괴 특성은 인가전압의 기울기와 방전관 내부의 질소기체 압력을 통하여 알아보았다. 방전관 인가전압의 기울기가 증가할수록 절연파괴 전압과 방전 시 소비되는 에너지량이 크게 상승되었고, 절연파괴 시간은 감소되었다. 방전관 내부 질소기체의 압력이 감소할수록 절연파괴 전압과 절연파괴 소요시간, 방전 소비에너지량이 크게 감소되었다. 결과적으로, 방전관의 과전압 보호 성능 및 수명을 증진시키기 위해서는 절연파괴 전압과 절연파괴 소요시간, 방전 시 소비되는 에너지량이 감소되어야 함을 알 수 있었다. 한편, 방전관 내부 질소기체 압력이 방전관의 자체 수명 및 과전압 보호 성능에 영향을 미침을 알 수 있었다.
