Plasma display panel aging method
View Patent ↗Disclosed here is a method of aging a plasma display panel. The aging method of the present invention contains a first aging period and a second aging period. In the first aging period, applying voltage Vd 1 to at least any one of the scan electrodes, the sustain electrodes, and the address electrodes suppress self-erase discharge that occurs in the wake of aging voltage generated by application of voltage in which the scan electrodes take a voltage level higher than the sustain electrodes. In the second aging period, applying voltage Vd 2 to at least any one of the scan electrodes, the sustain electrodes, and the address electrodes suppress self-erase discharge that occurs in the wake of aging voltage generated by application of voltage in which the sustain electrodes take a voltage level higher than the scan electrodes. The above aging method offers a power-efficient aging process with the aging time accelerated.
1. A method of aging a plasma display panel having scan electrodes, sustain electrodes, and address electrodes, in which voltage is applied to at least the scan electrodes and the sustain electrodes, said method comprising:
a first aging period in which aging is carried out by applying voltages alternately and continuously to the scan electrodes and the sustain electrodes, and in which at least any one of the scan electrodes, the sustain electrodes, and the address electrodes undergo an application of voltage for suppressing a first self-erase discharge, which is a self-erase discharge that follows an aging discharge, only when the scan electrodes carry a voltage level higher than the sustain electrodes; and
a second aging period in which aging is carried out by applying voltages alternately and continuously to the scan electrodes and the sustain electrodes, and in which at least any one of the scan electrodes, the sustain electrodes, and the address electrodes undergo an application of voltage for suppressing a second self-erase discharge, which is a self-erase discharge that follows an aging discharge, only when the sustain electrodes carry a voltage level higher than the scan electrodes.
2. The method of aging a plasma display panel of claim 1 , wherein the second aging period lasts shorter than the first aging period.
