Abstract
A method for setting an applied voltage in a plasma display panel is provided, in which a driving voltage margin is increased. A charge adjustment is performed by generating a discharge for changing a wall charge quantity without changing a polarity of the charging before addressing. In a coordinates space describing the relationship between the effective voltage between the first electrodes and the effective voltage between the second electrodes, a voltage range (Vt closed curve) that can generate a microdischarge for the charge adjustment is determined, and a waveform of an increasing voltage that is applied to the discharge cell is determined in accordance with a Vt closed curve.
