  • Influences of sustain voltage on wall charges and wall voltages are experimentally investigated in surface AC plasma display panels(AC-PDPs), in which electrode gap and width are $80\;{\mu}m$ and $270\;{\mu}m$, respectively. The filling gas is Ne-Xe gas mixture, and total pressures 300 Torr. Also it is found that the more amount of Xe mixing ratio makes the less wall charge and voltage for sustain voltage ranged from 140 V to 222 V. The response time has been delayed by adding a small amount of Xe to Ne in comparison with that without Xe. It is also found that the wall charge and voltage are reduced by adding a small amount of Xe to Ne in comparison with those without Xe.

  • Influence of sustain pulse-width on electro-luminous efficiency is experimentally investigated for surface discharge of AC-PDP. It is found that the firing voltage is decreased as the pulse-width is increased from $2\;{\mu}s$ to $8\;{\mu}s$ with sweeping frequency range of 10 kHz to 50 kHz. It has been found that the optimal sustain pulse-width is in the range of $3{\sim}4\;{\mu}s$ under driving frequency range of 30 kHz and 50 kHz, based on observations of memory coefficient, wall charge, and wall voltage as well as luminous efficiency.

  • One of the most important issues in AC PDP is the improvement of luminous efficiency. One possible method for achieving this aim is by increasing Xe partial pressure in discharge gas mixture. The increase of Xe ratio, however, causes the driving voltage to rise, even if brightness is increased. In this study, a new electrode shape is proposed. A test panel fabricated by using a new electrode shows that efficacy has improved by 25 % and sustain voltage has decreased by 20 % compared with the conventional structure.

  • 본 논문에서는 AC Plasma display panel(AC-PDP) 구동을 위한 Six-switch를 적용한 Three-level PDP Sustain 회로를 제안한다. 제안 회로는 기존 회로의 Sustain 스위치와 Clamp 다이오드의 내압이 절반이 되어 특성이 우수한 반도체 소자의 채택이 가능하며, 환류 전류가 저감되어 높은 전력 효율을 가지는 장점을 가지므로 AC-PDP 구동 회로 설계에 매우 적합하다. 본 논문에서는 기존 회로와 제안 회로의 전도 손실 계산 및 시뮬레이션과 실험 결과를 보였다.

  • Misfiring is usually observed at high ambient temperature in plasma display panel (PDP). This leads to bad image quality and limits the productivity of PDP industry. In this paper, experimental observations and improvement on the misfiring at high ambient temperature have been studied. In order to reduce the high ambient temperature misfiring different slope of ramp erase pulse corresponding to the temperature are applied. The experimental results show that the suggested method is quite effective for reducing the high temperature misfiring phenomena.

  • To replace the dual scan system by single scan in large ac plasma display(PDP), the addressing time should be reduced by modifying cell structure and driving circuits. Moreover. the luminance of the PDP can be also increased with the decrease in the addressing time. In this paper, various shapes of bus and address electrode have been investigated to reduce the addressing time in ADS driving method. The experimental results show that the addressing time can be reduced more than 30% compared to the conventional type by modifying the electrodes without reducing the luminance of the PDP.

  • Plasma display panel(PDP) have gained great attention due to their potential application to large-area display including HDTV. The luminance and luminous efficiency of PDP, however, should be improved to realize this goal. In this study, we examined experimentally the effects of phosphor thickness and discharge gap on the luminance and luminous efficiency of ac PDP. For the rib height of 110 ${\mu}m$, whereas the optimum phosphor thickness was about 30 ${\mu}m$. The optimum thickness of green phosphor was about 50 ${\mu}m$ for the rib height of $120{\sim}160\;{\mu}m$.

  • In AC-PDP, it is necessary to achieve high luminance efficiency, high luminance and high definition by adopting technologies such as high xenon concentration and long gap. However, it is very difficult to apply above technologies because they make many problems such as mis-discharge and high driving voltage. Especially, the reactive power of PDP must be reduced for satisfaction in international standard IEC62087. In this paper, we proposed CLHS driving method which is half sustain driver without energy recovery capacitor. In the experimental results, CLHS driving method reduced reactive power consumption about 10%. Also, CLHS driving method improved the luminance efficiency in all discharge loads. Therefor, the more the discharge load decreases, the more the luminance efficiency improves. When the discharge load is 20%, CLHS driving method improved 5.35%.

  • 보통의 AC PDP에서는 Ne, Xe 혼합가스를 사용한다. Xe %가 높아짐에 따라 PDP의 효율은 올라가지만 그와 함께 최초의 방전을 일으키는 방전 개시 전압 또한 올라간다. 이러한 이유로 실제 PDP에서 무한정 Xe %를 올릴 수는 없다. 그래서 우리는 Xe gas보다 원자번호가 낮은 불활성기체인 Kr gas를 첨가시킴으로써 동일한 효율에서 방전개시전압이 낮은 최적의 3원 가스 조성비를 찾아보았다.
