The present invention relates to a plasma display apparatus and driving method thereof, in which an afterimage occurring when the plasma display panel is turned on can be obviated and an erroneous discharge phenomenon and damage to elements can be prevented. A plasma display apparatus according to an aspect of the present invention comprises a plasma display panel including a scan electrode and a sustain electrode, and a controller for applying a sustain pulse, which is the first applied pulse, to the scan electrode and the sustain electrode for a predetermined time after the plasma display panel is turned on. The present invention is advantageous in that it can obviate an afterimage occurring when a plasma display panel is turned on and can prevent an erroneous discharge phenomenon and damage to elements by improving a driving apparatus of the plasma display panel.

Plasma display apparatus and driving method thereof

The present invention relates to a plasma display apparatus. The plasma display apparatus according to the present invention comprises a plasma display panel comprising a scan electrode, a set-up driver that applies a rising pulse to the scan electrode during a reset period, a set-down driver that applies a first ramp-down pulse before the rising pulse is applied to the scan electrode and applies a second ramp-down pulse after the rising pulse is applied to the scan electrode, and a scan pulse driver that applies a scan pulse having an amount, which is substantially the same as that of the rising pulse, to the scan electrode during an address period subsequent to the reset period.
