摘要： A method for driving a PDP is provided in which addressing having little influence from operating environment changes is realized without increasing withstand voltage of circuit components, so that a display is stabilized. The method comprises the step of keeping a scan electrode in high impedance state to a power source line over a part or the entire period of a selection waiting period before the scan electrode is biased to a selection potential level.

摘要： On a front substrate, a dielectric layer for accumulating the wall charge is formed, and inside the dielectric layer, a first electrode and a second electrode intersecting each other are formed with a predetermined pitch. The dielectric layer is not flat but is convex at the intersection of the first electrode and the second electrode, and the thickness in the direction of the discharge space from the second electrode at the intersection is larger than the thickness in the remaining area. Consequently, since the electric field distribution at the intersection is coarser than that at places apart from the intersection when discharge is sustained by causing an electric field distribution in the discharge space through the dielectric layer, discharge occurs not at the intersection but in four positions at places apart from the intersection, so that the luminous efficiency per discharge cell is improved.

摘要： A method of driving a PDP including alternately-arranged X and Y electrodes and A electrodes crossing the X and Y electrodes provides a recurring cycle of a resetting period, an addressing period, and a sustaining period. The method includes applying a ramp waveform in the resetting period. Discharge starting threshold voltages between the X and Y electrodes and between the A and Y electrodes are denoted by VtXY and VtAY, respectively. Voltages applied between the X and Y electrodes and between the A and Y electrodes at the trailing edge of the ramp waveform are denoted by VXY and VAY, respectively. An offset voltage of the voltage applied between the A and Y electrodes at the end of the sustaining period is denoted by Vaoff. In such a case, the voltage of a driving waveform for each electrode is set so as to satisfy the relational expression “2 VtAY−VtXY>2VAY−VXY−2Vaoff”.
