We successfully have fabricated an operable PDP panel with a 2-inch diagonal size by using the fully vacuum in-line sealing technology for the first time in the world. The sealing temperature of the two plates was around 330℃ which corresponded to a temperature about 120℃ lower than that used in a conventional air environment. The base vacuum level inside the panel before gas filling was about 5x10^-6 Torr at the time of sealing. Then, a Ne-Xe(4%)mixture gas was introduced into the panel-inside through a tubeless hole in the glass plate until 400 Torr. Subsequently, the 'hole-off' process was done by using frit sealing in the vacuum chamber. The hole-off time was negligible. Thus, the total elapsed time for the sealing processes was less than 6 hours, including the gas Flu and the hole-off processes. The panel wasp successfully operated with a starting voltage of 190 V driven by 50- kHz AC mode, giving a sufficiently high and uniform brightness for all the pixels.
