摘要： PROBLEM TO BE SOLVED: To provide techniques for reducing inefficiency of reset operation by a conventional interlaced driving system in a PDP device of a BOX-ALIS configuration.
SOLUTION: An interlaced driving system which handles two adjacent display lines (L) as one control unit (U) is employed for a PDP driving method of the PDP device of BOX-ALIS constitution, and odd-numbered and even-numbered Us (Uo, Ue) are driven for display alternately in display units (G1, G2) of fields and subfields. A reset discharge is generated only by the L and C of a U as an object of driving and display (plus side) to reduce unnecessary light emission. With a voltage waveform applied to the L and C of the plus-side U, a reset discharge is generated by a display electrode pair (X-Y) and with a voltage waveform applied to the L and C of the opposite-side U, a scanning electrode (Y) is held at 0V.
