We investigated the effect of Xe content variation on the luminous efficiency of two different sub-pixel types, i.e., segmented electrode in delta color arrayed enclosed sub-pixel (SDE) and conventional stripe barrier type, in an ac plasma display panel through three-dimensional numerical simulations. The conventional cell type was found to have higher VUV generation efficiency as compared with that of SDE structure, but as the Xe content increased, the SDE type showed higher improvements in efficiency due to the lower plasma loss to the barrier walls.

The address discharge characteristics by the various scan-low and common-bias voltages are investigated based on measured address discharge time lags and $V_t$ close-curve analysis. The scan-low voltages are changed under the same voltage difference between the X and Y electrodes during an address period. As the voltage difference between the scan and address electrodes is increased during an address period, the address discharge time lag is shortened but the background luminance is increased. It is found that the improved address discharge characteristics is caused by the effect of the higher external applied voltage during an address period than the accumulated wall charges during a reset period and the high background luminance can be prevented by applying an address-bias voltage during a rising-ramp period and low reset voltage.

The panels were fabricated to characterize the contamination of Magnesium Oxide (MgO) thin films by phosphors and ion bombardments in AC-PDPs. Forty-six inch WVGA panels of the surface and vertical discharge type were manufactured. The experiment was designed to investigate the relationship between the MgO thin films and phosphor contamination caused by ion bombardments in a plasma environment to produce a life time test. The contamination of MgO thin films by phosphors was investigated by way of X-ray photoelectron spectroscopy (XPS).

The real test panel with the $200{\mu}m$ discharge gap in a coplanar AC plasma display panel was investigated. The auxiliary electrode was placed between two sustain electrodes and used for providing wall charges and prime particle during sustain period. The luminous efficiency had the maximum value when the voltage of the auxiliary pulses was 20 ${\sim}$ 100[V]. The luminous efficiency of coplanar long-gap discharge with auxiliary electrode was 2.6 times as much as that of the conventional structure.

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.

The wall charge is major factor to determine the discharge characteristics. The minimum sustain voltage related to the wall charge decay were investigated as a function of aging time in AC plasma display panel. For the long time scale, the wall charge decay time is dependent on the aging time. The inverse time scale of the wall charge decay has the maximum value at around 3 hours aging time and then fell down.

We investigated the effect of sustain electrode gap variation with high Xe content in an ac Plasma Display Panel through two-dimensional numerical simulation to understand the inherent high luminous efficiency mechanism. For the low Xe content, the optimal sustain electrode gap turned out to be about 200 ${\mu}m$, but with higher Xe content, the VUV generation efficiency increased as the electrode gap increases beyond 200 ${\mu}m$. We found that it is due to higher electron heating efficiency in the cathode sheath under the condition of long electrode gap and high Xe content.
