The relationships between wall charges and driving voltage at each electrode in selective writing ADS method of AC-PDPs

摘要

The relationships between the driving voltage and wall charge distribution in the address period of surface discharge type AC Plasma Display Panel have been investigated. The quantity of wall charge on each electrode was detected simultaneously from the electrode current after applying only one addressing discharge pulse. The wall charge Qy on the scan electrode Y is nearly the sum of Qx on the address electrode X and Qz on the sustain electrode Z. The Qy was increased with increasing the driving voltage regardless of the kind of electrode, whereas the address time Td was decresed. The Qz and Qy were increased considerably with increasing the blocking voltage Vz, whereas Qx was decreased. The increase rate of Qx, Qy and Zq for increase in Vz were -13x 10~(-2) (pc/Vz), and 60x 10~(-2) (Pc/Vz) and 70x 10~(-2) (pc/Vz), respectively.
