In this paper, we showed the erosion characteristics of MgO protector layer releated to lifetime of plasma display panel(PDP). We observed MgO erosion characteristic as a functions of deposition conditions. 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.

A new high-speed drive method for the plasma display panel is proposed. In this method, the address period is inserted for the rest period of the sustain pulses and the priming pulse is applied on the entire panel at the same time overlapping with the sustain period. The ramp shaped priming pulse can be made with a simple drive circuit in this technology and the stable sustain discharge can be induced even by a narrow scan pulse in help of the space charge generated from the address discharge. From the experiments, it is ascertained that the priming pulse hardly influences the sustain discharge. Moreover, the voltage margin of the sustain discharge is almost constant though that of the address discharge broadens with narrowing the scan pulse width. And, if the time interval between the scan pulse and the sustain pulse is within $6{\mu}s$, the voltage margin of the address and the sustain discharges are unaffected though the applied position of the scan pulse is changed. High-speed driving with the address pulse of $0.7{\mu}s$ width was achieved and the address voltage margin of 20V and the sustain voltage margin of 10V were obtained.

This study uses neon, xenon, and helium gas mixture microdischarge to determine the effects of priming particles on the neon emission characteristics in an alternate current plasma display panel (AC PDP). The infrared (823 nm) and neon emission (585 nm) intensities are measured and compared in the blue cells in the case of new discharge with priming particles or conventional discharge without priming particles, respectively. It is found that the priming particles can produce a plasma discharge effectively even under the weak electric field condition, thereby resulting in reducing the neon emission intensity remarkably without sacrificing the IR emission intensity. As a result, it is found that the Ne emission intensity is reduced by about 46.4 % but the blue visible emission intensity is increased by about 15.2 % when compared with the conventional discharge without priming particles.

플라즈마 디스플레이 패널은 양극과 음극사이의 방전공간을 가진 많은 방전 셀로 구성되어 있다. 네온과 제논가스로 채워진 이 방전공간에서 전기방전이 일어난다. 전자온도가 방전조건에 의하여 정해지며 이온도를 통하여 제논의 함량에 따른 방전전압을 이론적으로 계산할 수 있다. 방전 셀 내의 플라즈마가 147 nm와 173 nm의 극자외선을 방출하고 이 자외선들은 형광물질을 여기하여 가시광선을 방출한다. 이러한 모든 과정에 대한 물리적인 메커니즘의 모델을 만들고 실험에서 측정된 데이터와 모델이 예시하는 결과를 비교한다. 실험 데이터는 이론 결과와 비교적 잘 일치하는 것을 관찰할 수 있다. PDP의 방전과 동작을 더욱 개선하기 위하여 새로운 물질이 필요하고 더 좋은 셀 구조가 요구된다.

A highly efficient sustaining driver is proposed for plasma display panels (PDPs). When the PDP is charged and discharged, the proposed sustaining driver employs an address voltage source used in an addressing period. A voltage source is used for fully charging the panel to the sustaining voltage, and an initial inductor current helps the panel discharge to 0 V. The resonance between the panel and an inductor is made by shifting the voltage and current bias level when charging and discharging the panel. As a result, the proposed circuit can reduce power consumption, switching loss, heat dissipation, and production cost. Experimental results of a 42-inch PDP are provided to verify the operation and features of the proposed circuit.

Comparison of one two-path single energy recovery circuit for plasma display panel (PDP) is shown in this paper. A single energy recovery circuit (SERC) is proposed to reduce cost for manufacturing PDP and there are two ways, one and two-path, in driving this circuit. Compared with one-path SERC, there are low power consumption, low surge current and high performance in two-path SERC. The results will be shown with 42-inch HD panel.

Nano-porous alumina was investigated as a protecting layer in an AC Plasma Display Panel. A 2 ${\mu}m$ thick nano-porous $Al_2O_3$ layer inserted with MgO was formed on the dielectric layer instead of the conventional 500 nm-thick MgO thin film. Both nano-porous $Al_2O_3$layer and inserted MgO were prepared by wet process. The luminance and luminous efficiency of 3-inch test panel adopting nano-porous $Al_2O_3$ was higher than that of the conventional PDP.

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.

The contact resistivity of the black interlayer which has been introduced between BUS and ITO electrodes in a plasma display panel was evaluated using two kinds of specially designed test electrode patterns. Of the two, type 2 pattern was able to evaluate the contact resistivity more successfully, which was calculated as about $250{\Omega}$ in the suggested test pattern structure.

A new electrode structure is proposed in this paper which can increase the discharge efficiency of plasma display panels and also decrease the panel capacitance by decreasing the electrode area effectively. Even with the decreased electrode area, the proposed structure could suppress the requirement for increasing the voltage and improve efficiency by limiting the discharge current.
