Abstract
A driving device of a plasma display panel for performing a reset period using a ramp pulse. The driving device changes the lowest potential of the ramp down pulse in response to temperature change in order to prevent or reduce low discharge or over-discharge due to the temperature change. The amount of wall charges in the pixels are maintained substantially constant over a temperature range to provide an optimal discharge condition, making it possible to prevent the discharge error and perform the low voltage address operation, in the address period.
