To investigate the aging process of AC PDPs manufacturing, Mg-Zr-O protective films were deposited on glass substrates by magnetron sputtering method, and made into macroscopic discharging cells. The aging of discharge cells was accomplished with different time, and discharging voltages (the firing voltage and the minimum sustaining voltage) of them were measured. Results reveal that the firing voltage Vf and the minimum sustain voltage Vs are reduced by about 18 V and 10 V in the initial aging process (0∼20 min) respectively, then tend to be constant as the aging time increases further. The XPS measurement suggests the density of states for valence band rises with the increase of aging time from 0 to 20 min, while valence band edge is slightly shifted to a low binding state. When the aging time exceeds 20 min, the electron structure tends to be in a stable condition gradually. Similar behavior is observed in both the relative intensity of (200) preferred orientation to (220) observed by XRD and surface toughness detected by AFM. The transformation of microstructure was observed.
