  • A new low-cost asymmetric current-fed energy-recovery circuit (ERC) for a plasma display panel (PDP) is proposed. LC resonant circuit biased by $V_s/2$ and composed of single switch is used as ERC on both sides of the PDP, slow discharging and fast charging times can be employed, and inductor currents are built up before the PDP is charged and discharged. Therefore, it features a low cost, fully charged/discharged PDP, zero voltage switching (ZVS), low electromagnetic interference (EMI), low current stress, no severe voltage notch, and high energy-recovery capability.

  • Plasma Display Panel(PDP) has been recognized as one of the most competitive display panel. Hence, the importance of PDP driving circuit is getting higher and higher. At the same time, it is strongly required for the driving circuit to be high efficiency, high stability, and cost effective one. In this work, a stable PDP driving circuit is developed by improving the circuit configuration. And the reliability and the productivity of the driving circuit are improved by using the Intelligent Power Module(IPM) technology. Finally operating characteristics of the developed IPM driving circuit are verified by using signal source board developed.

  • 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.

  • Effects of base vacuum level on the electrical and optical characteristics of the plasma display panel (PDP) were investigated. The relationship between efficiency and base vacuum level before filling discharge gas was analyzed. For the base vacuum level of $1{\times}10^{-4}$ torr, firing voltage of a 2-inch diagonal PDP panel was 232 V at the discharge gas pressure of 400 torr and luminous efficiency was 1.5 lm/W at 180V sustaining pulse. On the other hand for $1{\times}10^{-6}$torr, the firing voltage was reduced to 215 V and luminous efficiency was improved considerably to 2.5 lm/W. We successfully demonstrated the smooth operation of tip-less PDP fabricated using vacuum in-line sealing method.

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

  • We have measured the excited Xe atoms density in the $1s_5$ metastable states by laser absorption spectroscopy in accordance with various barrier ribs. In this experiment, the average density of one cell in the panel with stripe barrier rib has been measured to be $1.8{\times}10^{12}cm^{-3}$. The panel with close type barrier rib has been measured to be $5.1{\times}10^{12}cm^{-3}$.

  • Plasma display panel (PDP) televisions are facing to have a new chance to receive attention along with a boom in 3-D software and contents because PDP can provide the comfortable and realistic 3-D images. The PDP has three driving circuit boards such as X, Y and addressing boards. Cost effective driving waveform has already been reported to decrease the number of driving circuit board. Half bridge based sustaining driver can remove a sustaining driver in the X board. However, the biasing circuit in the X driving boards cannot be reduced because there are some drawbacks such as unstable gas discharge condition and unreliability of an address driver IC. In this paper, the half bridge based sustaining driver is considered and a simple address driver is proposed to remove one driving board, X driving board. The stable gas discharge condition, reliability of the address driver IC and the low cost can be obtained by the proposed circuit.

  • Main PDP panel efficacy improvement factors are discussed. A large panel efficacy improvement can be obtained through a combination of discharge efficiency improvement and phosphor improvement. Important design elements are a high Xe-content gas mixture, the application of a $TiO_2-layer$, and a new green phosphor with little saturation at high VUV-load. In a 4-inch color test panel with a conventional stripe-type cell configuration a white efficacy of 4.4 lm/W and a luminance of 5000 $cd/m^2$ is obtained for sustaining at 250V in addressed condition.

  • AC-PDP는 구조적으로 2장의 유리, 유전체, 전극으로 구성된다. AC-PDP의 전기적특성은 유전체의 물성에 크게 좌우된다. AC-PDP의 유전체는 주변 온도와 주파수에 따라 유전율 및 유전손실 특성이 달라지므로 온도와 주파수에 따른 유전물질의 물성변화와 panel의 전기적특성에 대한 연구가 필요하다. 본 논문에서는 온도와 주파수에 따른 AC-PDP내 유전체의 유전율 및 유전손실에 대한 특성에 대해 알아보고 4인치 test 패널을 제작하여 온도와 주파수에 따른 panel의 전기적특성 관계를 살펴보았다.
