  • Nowadays, itis inevitable trend to use high Xe gas contents for increase luminous efficiency and luminance in plasma display panel. However, the increase of Xe gas contents causes the driving voltage, although the brightness is increase. In this paper, we study the characteristics of electro optical according to Xe gas contents and gas pressure. Electro-optical characteristics were investigated by the discharge voltage, luminance and luminous efficacy measurements, respectively. With some increasing Xe gas contents and pressure, the electro-optical properties increased. However, the characteristics of electro-optical begin to be saturated, when too high increased Xe gas contents and pressure.

  • 본 논문에서는 방전유지전극사이에 유전체 공극이 존재하는 능선형상의 상판구조를 제안하였다. 이 구조는 상판의 방전 유지 전극사이 강한 전계를 이용하여 동작전압을 감소시킬 수 있고 이로 인한 Xe의 주입비율을 증가시켜 휘도 및 발광효율을 향상시킬 수 있는 구조이다. 실험에서는 6인치 테스트 패널을 사용하였으며 기체 압력을 450 torr로 유지하면서 Xe 함량을 10 %, 15 %, 20 %, 30 %, 50 %로 변화하여 실험하였다. 실험결과, 10 %의 동일한 Xe 기체를 주입한 결과, 제안된 구조를 적용할 경우, 방전개시전압과 방전유지전압이 각각 79 V, 74 V 감소하였으며 10 %의 Xe을 주입한 일반적인 구조와 50 %의 Xe을 주입한 제안된 구조의 휘도와 발광효율 비교에서 본 논문에서 제안한 구조가 비슷한 구동전압 범위에서 일반적인 구조에 비하여 효율은 50.9 % 향상되었고, 휘도는 33 % 향상됨을 알 수 있었다.

  • We reported an AC PDP structure with grooved front panel dielectric layer. The structure exhibits low breakdown voltage, better luminance, and better endurance to crosstalk in high Xe contents. It also shows less luminous efficacy then conventional structure because of the thinner dielectric layer, but we can apply the higher Xe contents to the grooved dielectric structure, which results in the higher luminous efficacy. We made experiments with the Xe contents from 4 to16% and total gas pressure from 400 to 600Torr. The grooved dielectric structure shows the improvement of 20% luminous efficacy and 17% luminance. The firing voltages lower about 40V at 600Torr and Xe 12, 16%. The discharge characteristics of grooved dielectric structure are verified also with 2D simulation.

  • To increase the luminance and luminous efficacy in the discharge for alternating current plasma display panel (ac PDP), the increment of Xe contents and long discharge gap are necessary. However, the driving voltage and the cost of driving circuit increases in the high Xe contents and long discharge path condition. In this paper, a long gap ITO hump electrode (LGH) model for discharge cells of ac PDP is evaluated in the various Xe contents($5{\sim}20%$). The discharge voltage of LGH structure is lower about 30V than that of ITa reference structure with same main discharge gap. The LGH structure has lower power consumption and higher luminance than those of reference structure, respectively. Also, the luminous efficacy of LGH structure is higher about 20% than that of ITO reference structure in the 20% Xe contents.

  • 휘도와 효율을 증가시키기 위해 Xe의 함유량을 높이는 연구가 계속해서 수행되고 있지만, Xe이 증가함에 따라 방전전압 또한 높아지는 문제는 여전히 해결하지 못하고 있는 실정이다. 본 논문 에서는 Xe gas 가 첨가됨에 따른 기체 방전의 특성을 실험 및 이차원 시뮬레이션을 통해 분석해 보았다. 방전 셀 내부에 Xe 가스가 첨가됨에 따라 방전의 휘도와 효율이 증가하게 되는 메커니즘을 분석하고 그에 따라 야기되는 방전전압의 증가 원인들을 고찰해 보았다.

  • AC-PDPs have recently achieved good performance and their image quality can sufficiently compete with the LCD TV. However, it is necessary more effort to improve the luminance and luminous efficacy in the PDP technology. The gas mixture ratio plays a very important role in discharge characteristics, but the mechanism of gas discharge is complex and complicated. In this paper, we investigate the mechanism of gas discharge with Ne+Xe miture ratio through zero and two dimensional fluid simulation.

  • In this paper, we investigate the characteristics of luminous efficacy as a function of Xe partial pressure in AC PDP. SDR structure has shown much larger increment of luminous efficacy compared with the conventional one especially below 10% Xe contents. The luminous efficacy around 4.0 lm/W is achieved with Ne-Xe10%, 400Torr in Monochrome green phosphor test panel under 10kHz continuous sustaining frequency.

  • The gas mixture ratio of PDP discharges plays a very important role in the discharge characteristics of a plasma display panel. The increase of Xe contents results in the increases of luminance and luminous efficiency while it also results in the increase of the breakdown voltage. The addition of He gas increases the brightness and the luminous efficiency. Especially, the luminance and the luminous efficiency have a maximum value when the partial pressure of He is about 10% of the total pressure for a standard plasma display panel with Xe fraction of $10\sim30%$.

  • Experimental measurements are reported and compared with the results of a two-dimensional fluid simulation for the investigation of the discharge characteristics regarding the change of the mixture ratio of Ne-Xe-He noble gases. The increase of Xe contents results in the increases of luminance and luminous efficiency while it also results in the increase of the breakdown voltage and the discharge time lag. The addition of He gas increases the brightness and the luminance efficiency. When Xe partial pressure is low, the luminance efficiency increases with the amount of He at the same total pressure. When Xe partial pressure is high, however, the luminance efficiency has a maximum value when the partial pressure of He is about 10% of the total pressure for a standard AC PDP cell with Xe fraction of $10{\sim}30%$.

  • The temporal dark- and bright-image sticking phenomena were examined relative to the He contents under 11% Xe content in the 50-in HD and FHD AC-PDPs with a ternary gas mixture (Xe-He-Ne). To compare the temporal dark- and bright-image sticking phenomena under various He contents, the differences in the disappearing time, display luminance, perceived luminance, infrared emission, color coordinate, color temperature, and discharge current before and after discharge were measured under 0, 35, 50, and 70% He contents. It was found that temporal dark- and bright-image sticking were reduced in proportion to the increase in He %. Thus, a high He content contributes to the reduction of temporal dark- and bright-image sticking.
