Abstract
A driving device for a plasma display panel. The driving device generates rising and falling ramp signals having a respective constant slope regardless of a change in operating temperature. An optimal discharge voltage is maintained at high and low temperatures by the rising and falling ramp signals having a respective constant slope to secure an operation margin, thereby preventing a discharge degradation such as an incorrect discharge from occurring. Accordingly, this can cause the reliability of a plasma display device including the driving device to be enhanced.
