A new low-cost energy-recovery circuit (ERC) for a plasma display panel (PDP) is proposed. It has two auxiliary switches clamped on a half sustain voltage, 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.

A new energy-recovery- sustain circuit suitable for a Plasma Display Panel(PDP) application is proposed. The proposed circuit features the low device voltage stresses, essential to design a power efficient and low cost PDP driver circuit. The proposed circuit is demonstrated experimentally for driving a 42 inches plasma display panel.

A new driving waveform was proposed to reduce the cost in PDP-TV based on Vt close curve by eliminating the common (X) board under the conventional 42-inch panel structure. Due to the serious misfiring problem during a sustain-period when applying the new driving waveform, the wall voltage was measured and analyzed after the reset-period using Vt close curve. As a result of adopting the proposed driving waveform designed using Vt close curve analysis, the cost of PDP module could reduce compared with the conventional PDP module without any misfiring discharge.

This paper reports the cooling performance of a PDP(plasma display panel) with a heat spreader by means of numerical analysis. Due to the simplifications and assumptions inherent in the analysis, computed results are found to differ those of the experiment by 13%. Calculation shows a maximum temperature of $65^{\circ}C$ for the plasma glass, as opposed to the allowable temperature of $90^{\circ}C$, producing a temperature difference of $25^{\circ}C$ between the upper and lower regions. This is enough to cause cracks in the plasma glass. In order to avoid this, more ventholes are added at the upper center region of the back cover, thereby causing a $3^{\circ}C$ drop in the maximum temperature, which reduces the temperature difference to $12^{\circ}C$. The new design gives more uniform temperature distribution across the plasma glass.

PDP(plasma display panel)is expected to be the standard of the next generation display devices. However, there is a serious problem. That is disturbances are occasionally observed in gray scales and colors when moving images are displayed on PDP. Various methods have been presented to reduce these disturbances. But the picture quality of PDP is not yet sufficient. We developed optimized-modified binary coded light emission scheme. Simulated result show the improving image quality. Also we have simulated and estimated various proposed methods.

Over 5lm/W white luminous efficacy was obtained by 11" color test panel with narrowed discharge electrodes combined with high Xe partial pressure. By using optical spectroscopic methods, it was suggested that the electron heating efficiency is the most significant to improve the plasma efficiency in our experimental conditions.

In this paper, we showed the erosion characteristic of MgO protector layer releated to lifetime of plasma display panel(PDP). We observed MgO erosion characteristic as a functions of deposition conditions, pressure and distance between electrodes. In RIE condition of Xe gas, the lowest erosion rate appears in the conditions of no heating bias voltage -30V and pressure 5mtorr. In general, as deposition rate increases, erosion rate decreases. In real panel, when the gap distance between electrodes is narrow and the pressure is low, the heavy plasma damage appears. Also, the surfaces between electrodes and on the bus electrode are extremely damaged.

We performed a discharge analysis on ac plasma display panel through the numerical simulation of the EF (Energy Fluid) model using the electron's energy equation. When it is compared to the results of commonly used LFA (Local Field Approximation) model, there is a clear difference in the spatiotemporal distribution of Xe excited species. In particular, the experimentally observed striation phenomena in the anode region could be observed in EF model and the occurrence of the striation was attributed to the ionization and excitation instability due to the streaming electrons in the anode region plasma.

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.
