Abstract
A method for aging process in a PDP which is able to determine an ending time of the aging process comprises the steps of: starting the aging process by supplying source voltage to the PDP; and defining the aging ending time through change of current waveform by monitoring the change of current waveform applied to the panel, and thereby problems such that discharge characteristics of the panel become unstable due to the lack of aging time and phosphor is deteriorated and processing tack-time is reduced due to over-aging can be solved.
