<p>A driving method as well as a circuit of a plasma display panel is provided in which a rate of increasing voltage at start of a discharge is reduced, a reset period is shortened, and an excessive discharge in the reset period is avoided. The plasma display panel 1 comprises plural cells each of which emits light when a discharge is generated between a pair of display electrodes X and Y. Charge quantities of all cells are equalized in a reset period. In a bias period of the reset period, a current is supplied from a constant current circuit 93 to cells so that an increasing voltage is applied to the pair of display electrodes, while a capacitance element C3 is connected in parallel with a cell, so that an output current Ic of the constant current circuit 93 is distributed to the capacitance element C3 and the cell.</p> |
